Fuselage

Van's Aircraft offers a "QuickBuild" option for the fuselage. I decided that in order to have the airplane flying in the quickest time it would be nice to have the fuselage quick built by Van's quick build team called "Famous Secret" located in the Phillipines. We also ordered the quickbuild wings at the same time.

RV14A Empennage KitIt took 8 months, almost to the day, from the time we ordered the quickbuild kits until we received them at our hangar.

A QuickBuild fuselage is approximately 75% complete. The majority of the aluminum structure is riveted together. All parts are primed before assembly.

Delivery Day!

RV14A Quickbuild Delivery

We made arrangements to have our quickbuild kits delivered by Tony Partain. They did a great job and they really know what they are doing!

RV14A Quickbuilds On The Truck

Here you can see our kits loaded on the truck. We were the fourth delivery that they made on this trip.

RV14A Quickbuilds Unloading From The Truck

There is a hoist system built into the roof of the freight trailer.

The fuselage was offloaded using the hoist to set it down on a large dolly and we pushed it into the hangar...easy!

There were only three of us at the hangar to do the unloading: the driver, my wife, and myself. We had no problems.

*I wouldn't want less than three because the wings are unloaded by hand without the hoist and it would be very tricky to unload with only two present.

RV14A Quickbuilds Fuselage Firewall

The fuselage was placed on a dolly that they had on the truck and we pushed it into the hangar.

RV14A Quickbuild Fuselage Stuffed With Parts

The Van's packagers take every advantage of space as you can see they stuffed the fuselage with parts wrapped in paper!

There was another large box offloaded which contained smaller parts, hardware, and of course the builder's manuals.

RV14A Quickbuild Fuselage Side View

*You can see the box I was referring to in the upper right hand corner of this photograph leaning against the hangar wall.

RV14A Quickbuild Fuselage Packing Paper

Now the unwrapping and inventory can begin!

This is one of the three mounds of paper that all of the parts were wrapped in.

RV14A Quickbuild Fuselage Side View

This is what was in the box...

*Make sure to check every scrap of paper!

RV14A Quickbuild Fuselage Parts

This was in the box too!

Better get more shelves...

RV14A Quickbuild Fuselage Empty View

This is the fuselage after it was emptied from all of those parts

*The RV14 fuselage kit is only the forward half of the entire fuselage. The aft half or "tailcone" is built in the empennage kit.

According to Van's Aircraft these "Quick Build" kits are built so that they are universal and it is up to each individual builder to do (or undo) the items that pertain to tri-gear or taildragger models so be sure to go through the builder's manaul and check each step to see what is left to be done in order to complete the front fuselage section.


Shoulder Harness Clips

As I am getting the aft tailcone section (located in our garage) ready to join to the front fuselage section (located in our hangar), I began to work on some of the small individual parts that will be attached along with the tailcone when it finally arrives at the hangar location.... they are 24 miles apart from each other.

If you have been following along with the build process some of these parts are described in the end of the tailcone section.

These are the shoulder harness lug clips (F-01406D). They need to be separated from each other.

*The reference page for this is on page 30-05, step 3 of the builder's manual.

Shoulder Harness Clips

Reference lines were drawn for guiding me when I do the cuts on the bandsaw.

Separating Shoulder Harness Clips

Here I am making the cuts on the bandsaw to separate the shoulder harness lug clips (F-01406D).

Separated Shoulder Harness Clips

Here are the separated shoulder harness lug clips (F-01406D). The holes and edges still need to be deburred.

Shoulder Harness Lugs

Since I had the bandsaw out I decided to separate the shoulder harness lugs (F-01406E).

Shoulder Harness Lugs

Again, I drew guide lines so that I could make the cuts on the bandsaw.

Separating Shoulder Harness Lugs

Separating the shoulder harness lugs (F-01406E) on the bandsaw.

Separated Shoulder Harness Lugs

Let there be two!

The shoulder harness lugs (F-01406E) still have to be deburred.

Rudder Pedal Pads

Might as well separate the brake pedal pads (CS-00018A) as long as I have the bandsaw out....I think there's a pattern here!

Page 33-02, step 1 in the bulder's manual is where they talk about the brake pedal pads.

Separate The Rudder Pads

I drew reference lines to guide me on the bandsaw.

Separating The Rudder Pedal Pads

Here I am separating the brake pedal pads (CS-00018A) on the bandsaw.

Separated Rudder Pedal Pads

Now there are four!

Debur Shoulder Harness Clips

Back to the shoulder harness lug clips (F-01406D), I final reamed the holes and deburred the edges and I scuffed the surfaces with ultrafine gray ScotchBrite pads in preparation for priming.

Debur Shoulder Harness Lugs

These are the shoulder harness lugs (F-01406E), the holes have been final reamed but the edges have to be deburred and part of the lug needs to have a 1/16" wide chamfer.


Chamfer Lines For Shoulder Harness Lugs

Here are the layout lines for the chamfer on the shoulder harness lugs (F-01406E).

According to step 5 on page 30-05 of the builder's manual there needs to be a 1/16" wide by 1/32" deep chamfer on the upper edges aft of the bends.

*I used a fine file to make the chamfer, it doesn't take too long to do.

Chamfered Shoulder Harness Lugs

This is what the chamfer looks like. I also scuffed the surfaces with ultrafine ScotchBrite pads in preparation for priming.

Machine Countersink Shoulder Harness Lugs

Next, the seven aft holes in the shoulder harness lugs (F-01406E) have to be machine countersunk to accept a .025" dimpled skin.

*Make sure to look on page 30-07 to see that there will be AN426AD4-4 rivets attaching these lugs to the aft fuselage assembly so use a #30 dimpled hole for your machine countersink reference.

Countersunk Shoulder Harness Lugs

Now the shoulder harness lugs (F-01406E) have been countersunk to accept a #30, .025" dimpled skin.

Primed Shoulder Harness Pieces

I washed all of the shoulder harness parts with acetone and then primed them with DupliColor DAP 1690 self etching green primer.


ELT Bracket

The ELT antenna bracket (F-14117) was the next item I worked on.

Deburred ELT Bracket

I final reamed the holes and deburred all of the edges of the ELT antenna bracket (F-14117) and scuffed the surfaces with an ultrafine ScotchBrite pad in preparation for priming.

Primed ELT Bracket

After washing the ELT antenna bracket (F-14117) with acetone, I primed it with DupliColor DAP1690 Self Etching green primer.

Riveted Shoulder Harness Brackets

After the shoulder harness parts (F-01406D and F-01406E) had dried for a day, I riveted them together with AN470AD4-5 rivets which were set using our pneumatic rivet squeezer.

Referencing page 30-06, steps 2 and 3 of the builder's manual, an AN4 .25" bolt was inserted into the large hole so that alignment between the two parts could be maintained while the rivets were being set by the pneumatic squeezer.


Fuselage Things To Do

Now that the empennage kit has been completed we are "shifting gears" to focus on what needs to be done to our "Quick Build" fuselage kit to get it ready to join the two halves.

Beginning in section 26-01 of the builder's manual we begin to go through all of the construction steps to see what needs to be completed.

We got to page 26-10 and see in steps 4-18 we need to do some work to make this "unibuild" into a tri-gear RV14A. The arrows point to some of the to do lists.

The number 1 needs to have a square hole cut out for the main landing gear.

Number two needs to have the hole match drilled to #22 and then enlarged with a unibit to 11/16".

Numbers 3-5 need to have the center holes final drilled to #27.

*These steps have to be done on both the left and right sides.

Fuselage Step Cover To Remove

There are step plate covers temporarily installed with pop rivets that need to be drilled out, these are for taildraggers and in tri-gear models is where the step plates go.

Fuselage Step Cover To Remove

This is the (F-01484A-L and F-0148A-R) tail dragger cover plates that need to be removed.

There are several more items that need to be done, not many and we got to section 29 so far but still have more steps to review.

*From what we have seen so far, the construction and quality of workmanship has been excellent.


Baggage Bin Bulkhead To Rivet

The left baggage bin bulkhead (F-01406A-L) needs to have eight K1000-08D nutplates installed.

The nutplates have been clecoed into place.

Baggage Bin Bulkhead To Rivet

I clamped the bulkhead to the bench so that the riveting process can proceed.

Hand Squeezing Nutplates In Baggage Bin Bulkhead

I am using our hand squeezer to rivet the K1000-08D nutplates to the left baggage bin bulkhead (F-01406A-L).

*The plans call for AN426AD3-3 rivets to be used which is okay, but I found that AN426AD3-3.5 rivets to be much better.

I used these size rivets for the installation of the nutplates on the rest of the baggage bin bulkheads too.

Hand Squeezer Setup

This is the setup that I used with the hand squeezer.

Nutplates In Place

The eight nutplates have been installed on the left baggage bin bulkhead (F-01406A-L).

Nutplate

Here's a closeup, the rivets are AN426AD3-3.5

Nutplates Clecoed To Baggage Bin Bulkhead

The K1000-08D nutplates have been clecoed to the right baggage bin bulkhead (F-01406A-R).

Baggage Bin Clamped To Table

Just like before, I clamped the bulkhead to the bench.

Nutplates In Place

The eight K1000-08D nutplates have been riveted to the right baggage bin bulkhead using AN426AD3-3.5 rivets.

Nutplates Clecoed In Place

K1000-08D nutplates have been clecoed to the center baggage bin bulkhead (F-01406C).

Riveting Nutplates

Here I am riveting the K1000-08D nutplates to the center baggage bin bulkhead (F-01406C).

Nutplates In Place

The K1000-08D nutplates are in place.

Nutplates In Place

The center baggage bin bulkhead (F-01406C) as viewed from the other side.

You may have noticed that one side of the bulkheads are primed and the other sides aren't. That is because when I prime the cockpit interior I intend to use a water based painting system and just want to have a different primer recommended to go under the topcoat paint.


Fluting Baggage Bin Bulkhead

Now the fluting process begins on the baggage bin bulkheads (F-01406A-L and F-01406A-R) so that proper hole alignment around the perimeters of the bulkheads can be maintained.

* This is called for in step 6, page 30-02 of the builder's manual.

Along with the fluting pliers I also had my "smooth jawed" duckbill pliers and my breaking pliers in case I needed them. I didn't need the breaking pliers but the duckbill pliers came in handy around the small tabs at the bottom of the bulkheads.

Fluting Baggage Bin Bulkhead

The left baggage bin bulkhead (F-01406A-L) was clecoed into position to check for fit first.

*You'll find that if you have primed anything that during the fluting process some of the primer will get scratched up so get ready for touch ups!

Adjusting Baggage Bin Bulkhead Tab

There isn't a lot of fluting that needs to be done as you can see here but make sure to check the fit in the area of where the baggage bin bulkhead tab meets the top longeron.

The left side didn't need to be adjusted any but the right side did on ours.

*Don't start cutting and filing yet, wait until all of the bulkheads are clecoed into place before you make any adjustments to the area where these tabs intersect the longerons.

Fluting Baggage Bin Bulkhead

Here I am fluting the left baggage bin bulkhead (F-01406A-L).

Fluting Baggage Bin Bulkhead

Next I clecoed the right baggage bin bulkhead (F-01406A-R) into place to check for fit.

Baggage Bin Bulkheads

All of the baggage bin bulkheads (F-01406A-L, F-01406A-R, and F-01406C) are clecoed into place.

*This is a good time to check the fit in the area I was talking about earlier where the baggage bin bulkhead tabs intersect the top longeron.

Adjusting Baggage Bin Bulkhead

This is the right baggage bin bulkhead (F-01406A-R) and I had to open up the gap around the tab where it intersected the right top longeron (F-01418B-R) outside edges. It wasn't off by much but just enough that it was rubbing against the longeron and would have caused some problems later.


Touch Up Paint

Here is one of the places I had to lightly sand (600 grit sand paper) and prime. There were only a few minor scratches but might as well take care of them now.

Bend Tabs

Step 8, on page 30-02 of the builder's manual instructs that these tabs on both the right and left fuselage skins (F-01473-L and F-01473-R) be bent outboard 3/32".

*I gently did this with my "smooth jawed" duckbill pliers using a line I drew as my reference.


Brake Pedal C Channels

Back to the brake pedal pads, there are several parts that make up the rudder pedals and brakes. These are the brake pedal "C" channels (CS-00018B) and the small tab at the right is the bearing block template which will be used later as a guide when drilling holes to mount the rudder system.

Step 2, on page 33-02 instructs that these parts need to be separated so I used our bandsaw to do that.

Brake Pedal C Channels

First I marked my cut lines.

Separating Brake Pedal C Channels

Now I am using the bandsaw to separate the parts.

There are four brake pedal "C" channels (CS-00018B) plus the bearing block template.

NACA Vent Brackets

Since I had the bandsaw out I decided to separate the two NACA vent brackets (F-14186-L and F-14186-R) as well.

*This is step 3, on page 29-21 of the builder' manual.

Separating NACA Vent Brackets

Here I am separating the NACA vent brackets using our bandsaw.

NACA Vent Brackets Ready For Priming

I deburred the edges and scuffed the surfaces with a ScotchBrite ultrafine gray pad in preparation for priming, which I will do later because I still need to do some work on these so that the flow vent can be installed with screws.

*The (SV-5) "Whisper Flow Vent" was not included in our kit and I asked another RV14 builder if it was in his kit and he said it wasn't in his either.

Apparently they are no longer available so I guess the (SV-6) aluminum vents from Van's Aircraft will have to be purchased separately. They are available in black or clear aluminum and are supposed to be a direct replacement for the (Plastic SV-5's) but they are expensive.

Brake Pedal C Channels Separated

Back to the four brake pedal "C" channels (CS-00018B) which have been separated on the bandsaw, now everything has to be deburred.


Brake Pedal C Channels

All of the brake pedal "C" channels (CS-00018B) have been deburred, the #30 holes have been final reamed and deburred, and the surfaces have been scuffed with gray ultrafine ScotchBrite pads in preparation for priming.

*With all of those lightening holes to debur and all the edges to do, these took a couple of work sessions so I will prime them later.


Brake Pedal Pads

Now it is time to "tackle" the brake pedal pads (CS-00018A).

These are going to take awhile to debur, there are a lot of lightening holes plus the machining process that was used to bend the sides left some marks that will have to be addressed; I think you can see the lines the tooling made on the top surfaces of these pads and there are additional lines along the sides. The good thing is, they are plenty beefy!


Jilson Shears

You might have noticed that I have been jumping from one section of the builder's plans to another and that is because part of our project is in our hangar 24 miles away and part of it is in our home garage. In order to save some mileage on the vehicles I work on smaller projects at the home garage and then go out to the hangar to work on the forward "QuickBuilt" fuselage to finish the several items that need to be completed before we join the front fuselage to the tailcone section.

The next task I want to do is cut out the areas (step 7, page 26-10) for the landing gear to be "slid" into on the front fuselage. This is going to be kind of tricky because most of the front fuselage is already together and the working space, if you are trying to make the cut from above looking down towards the bottom skin, is very limited so in order to cut out the rectangles for the landing gear I am going to have to make my cuts from underneath looking up....oh boy!

Luckily I saw a guy using Jilson Monodex Shears to cut inside holes so I bought a pair to do the cutouts for the landing gear. *These cost $31.95 and are part number JS12 from Aircraft Tool Supply.

Layout Hole In Scrap Aluminum

I have never used Jilson Shears before so I thought I would get a piece of aluminum and set it up like I would if I were doing the actual cutout on the front fuselage before I did it for real.

First, I drilled #40 holes in each of the four corners so that I would have reference points for the rectangle. Then I took a fine line Sharpie and connected the dots to get the outline of the rectangle that was going to be cut. The blade that does the cutting on the shears is about 1/16" wide but you need to drill additional 9/32" holes inboard of the four #40 corner holes already drilled to manuever with. Then insert the cutting blade and make the straight cuts.

Rectangle Cutout

Here is my first go at it, not bad, not great, just remember to stay within the lines!

Final Filing On Rectangle Cutout

I got better on the second attempt.

Gear Cutout In Bottom Skins

Now for the real cut....you can see the space that I have to work in, it couldn't be done from above, it's too tight for my comfort level.

First I drilled the four #40 holes from above just like I did on the practice piece, then I drew lines underneath to connect the "dots" for my rectangle outline. The 9/32" holes were drilled for the cutter blade access and then back underneath I went to cut out the inner rectangle making sure to stay a safe distance from the edge marks. File work is next in order to finish the cutout.

Step 4, on the same page 26-10 of the builder's manual also instructs the builder to use a #22 drill to open up the large hole at the corner of the rectangle area (in the F-01483-L and F-01483-R bottom skins) and after that is done, for RV14A models, the #22 hole is then enlarged to 11/16" using a step drill and then the hole was deburred. *I did this also from below looking up!

If you look closely, you can see where some nutplates will be added later but before you add the nutplates the center holes have to be drilled larger with a #27 bit.

*There are five points that need to have #27 holes drilled. They are indicated in figure 1, and are step 12, on page 26-10 of the builder's manual. The holes were final drilled and all deburred for both the left and right side of the front fuselage.

Gear Cutout In Bottom Skins

Just like the left side, this is the right side and steps 7, 4, and 12 on page 26-10 of the builder's manual were completed.

File work will be done in a later section.

Cover Plate

Van's temporarily "pop" riveted (F-01484A) cover plates to the fuselage but since this is going to be a tri-cycle geared airplane I needed to remove them. This is where the step to get up over the wing into the cockpit will be located.

There were also more temporary "pop" rivets added to keep the rear skins in place during shipment so I drilled them out and replaced them with 3/32" clecos to hold everything together temporarily.

Cover Plate

The cover was removed from the left side too.


Deburring Brake Pedal Pad

Back to deburring the brake pedal pads....As you can see the metal is pretty thick...about 3/16" I am using flat and round files to do the edges, the surfaces will have to be sanded.

Deburring Brake Pedal Pad

In this photograph you can see the machining line that I mentioned earlier. The lines run from one hole to the other, I'm not sure if this could be a stress riser but I intend to sand them out.

These brake pedal pads have a lot of work to get them ready for priming and it took several work sessions to complete the task.

Deburring Brake Pedal Pad

The machining line (indicated by the red arrows) is a little deeper on the sides and they definitely have to be removed.


Deburring Brake Pedal Pad

Here I am final reaming the #30 holes and will debur them.

Step 3, on page 33-03 of the builder's manual instructs that the attach points for the hinge and master cylinders be final drilled to #12 size in each of the brake pedal pads (CS-00018A) and those were drilled and deburred at this time as well.

Primed Brake Pedal C Channels

Remember the brake pedal "C" channels (CS-00018B)? I washed them with acetone and then primed them with Dupli•Color DAP 1690 self etching green primer.


Final Sized Gear Left Side Cutout

Back out to the hangar...my wife final sized and deburred the left gear opening in the left bottom skin(F-01483-L). She used a combination of flat files to complete the task.

Enlarge The Mounting Holes

Step 6, on page 26-11 of the builder's manual instructs to enlarge a #40 hole, indicated in figure one to 9/16" using a step drill, the other two holes are to be final drilled to #19 size as per step 7, on page 26-11. The holes were deburred also.

Countersink Cowling Attachment Plates

Step 3, on page 28-07 of the builder's manual instructs that all of the #40 holes in the two cowl attach plates (F-14133-1) need to be machine countersunk to accept an AN426AD3 type rivet head.

*You have to make sure that the countersink will be flush from the bottom side so since the front fuselage is sitting on a stand and the cowl attach plates are already attached to it, I had to do the countersinking from below looking up!

Countersink Cowling Attachment Plates

Nice!


Deburred And Sanded Brake Pedal Pads

Finally, the brake pedal pads (CS-00018A) are finished being deburred and sanded!

I washed all of them with acetone in preparation for sanding.

Primed Brake Pedal Pads

I primed the brake pedal pads with Tempo A702 green zinc phosphate primer.

Brake Pedal Z Channels

Step 3, page 33-02 in the builder's manual instructs that the brake pedal "Z" channels (CS-00018C) be separated into eight parts.

Separating Brake Pedal Z Channels

Here I am separating the brake pedal "Z" channels (CS-00018C) using our bandsaw.

Separated Brake Pedal Z Channels

All of the brake pedal "Z" channels (CS-00018C) have been separated and I have begun the deburring process.


K1000-6 Nutplates

As per step 4, page 26-11 of the builder's manual, ten (K1000-06) nutplates need to be dimpled so that they can be installed later onto the (F-01483-L and F-01483-R) fuselage center bottom skins around the area of the lower gear brace.

*I used a #40 reduced diameter female die set so that the body of the die did not damage the center portion of the nutplate.

Dimple Nutplates

Here is what it looks like dimpling the (K1000-06) nutplates on our DRDT2 dimpler.

Dimpled Nutplates

These are the (K1000-06) nutplates after they have been dimpled.

Final Sizing Landing Gear Slot

Meanwhile, my wife continued to final size and debur the opening on the the (F-01483-R) right bottom forward fuselage skin where the landing gear is attached as per step 8, page 26-10 of the builder's manual.

Break Edge On Center Skin

Step 8, on page 26-11 of the builder's manual instructs that the aft edge of the (F-01484) bottom center skin be broken upwards so I used our hand seamers and broke the edge accordingly.

Break Edge On Center Skin

Here you can see both sides of the aft edges of the (F-01484) center bottom skin have an edge break.

Cowl Attach Nutplates

As per step 4, page 28-07 of the builder's manual I riveted (K1000-08D) nutplates to the (F-14133-1) cowl attach plates using a hand squeezer.

*I substituted AN426AD3-4 rivets because the AN426AD3-3.5 rivets called for didn't seem to be long enough.

Cowl Attach Nutplates Installed

These are the (K1000-08D) nutplates installed onto the (F-14133-1) cowl attach plates.

Cowl Attach Nutplates Installed

Here's what they look like from the bottom looking up.
(This is the left side.)

Cowl Attach Nutplates Installed

Here's another view.
(This is the right side.)


Installed Center Bottom Skin Nutplates

As per step 10, page 26-11 of the builder's manual, the (K1000-06) nutplates that we dimpled earlier were riveted to the (F-01484) center bottom skin using AN426AD3-4 rivets which we set using our 3x rivet gun equipped with a swivel head mushroom set and a long bucking bar.
(This is the left fuselage side.)

The (K1000-06) nutplate called to be attached in step 11, page 29-04 of the builder's manual was also installed at this time as well. We set these nutplates with AN426AD3-5 rivets in substitution for the AN426AD3-4 rivets called for in the plans (detail A) on page 29-04 because as before the -4 sized rivets didn't seem to be long enough.

Installed Center Bottom Skin Nutplates

*This is the right fuselage side. Everything that we did above was done to this side as well.


Ream Holes In Z Channels

Here I am final reaming all of the #30 holes in the (CS-00018C) brake pedal "Z" channels and then each hole was deburred.

Ream Holes In Z Channels

There are eight (CS-00018C) brake pedal "Z" channels that need to be final reamed, deburred, and then the surfaces scuffed in preparation for priming.


Brake Pedal Side Plates

These are the (F-1052B) brake pedal side plates.

Final Drill #12 Holes

All of the #30 holes were final reamed and deburred. Step 3, page 33-03 of the builder's manual instructs that all of the brake pedal hinge points and the master cylinder attach points be final sized with a #12 drill bit so that was done at this time and the holes were deburred.

#12 Drill Bit

#12 Drill bit.

Brake Pedal Side Plates Deburring

Now all of the edges need to be deburred.

Brake Pedal Side Plates Edges

The edges are kind of rough.

Brake Pedal Side Plates Gouges

Two of our side plates had some long scratches that needed to be addressed as well.


Prime Z Channels

Back to the (CS-00018C) brake pedal "Z" channels, after they all have been deburred, and the surfaces scuffed, I washed them with acetone in preparation for priming.

Prime Z Channels

I primed the (CS-00018C) brake pedal "Z" channels with DupliColor DAP 1690 self etching green primer.

Paint Brake Pedal Pads

It was a good day for painting so I painted the four (CS-00018A) brake pedal pads with DupliColor DA 1600 gloss black acrylic enamel.

Painted Brake Pedal Pads

Nice!

Paint Brake Pedal C Channels

I also painted the four (CS-00018B) brake pedal "C" channels with DupliColor DA 1600 gloss black acrylic enamel.

Painted Brake Pedal C Channels

Nice!


Polished Brake Pedal Side Plates

After the (F-1052B) brake pedal side plates were deburred, I decided that I wanted them to have some "bling" so I polished them with the buffing wheel and will later coat them with clear finish.

I also fabricated four (F-1097) spacers from AT6-058x5/16 6061- T6 aluminum tubing as instructed in step 1, page 33-03 of the builder's manual.

Might as well polish them too!

Polished Spacers

Nice!


Painting Brake Pedal Z Channels

I painted the eight (CS-00018C) brake pedal "Z" channels with DupliColor DA 1600 gloss black acrylic enamel.

ProtectaClear

This is the "brush-on" Everbrite "ProtectaClear" coating that I used to finish the four (F-1097) spacers and two of the (F-1052B) brake pedal side plates with.

*I have used this product before on smaller parts that I have polished and it worked really well.
It is self leveling and smoothes out with no brushmarks but I wasn't sure if it would work as well on a larger part like the side plates. That is why I only coated two of the side plates at this time.
There is an aerosol version of ProtectaClear, I want to try it on the remaining two side plates.....right now I am waiting for it to arrive from the shipper.... stay tuned!


Aerosol ProtectaClear

This is the aerosol version of Everbite's ProtectClear.

I painted the remaining two (F-1052B) brake pedal side plates with this.

*I did not like the aerosol ProtectaClear, it left "air bubbles" in the finish coat that was unacceptable so I ended up having to go back and sand the bubbles out with 1000 grit sand paper and recoat the side plates.
I did not have to do this with the "brush-on" version which ended up giving me much better results.

Of course this could all be a result of user error but I would have to recommend the "brush-on" ProtectaClear.


Clocking Lower Gear Brace

As per step 2, page 29-03 of the builder's manual, (F69-F-04x02) brass elbows need to be installed onto the (U-01402) lower gear braces.
If you look at figure 2 on that same page you will see that these brass elbows need to be clocked to a 6.9° angle. In order to do that I put a piece of masking tape opposite to where the brass fitting attaches to the lower gear brace, then, using a protractor I drew index lines corresponding to the desired angle so that when the brass elbows are tightened into position the centers of the retaining nut will line up with the mark.

Installed Elbows On Lower Gear Brace

Using some Loctite 567 thread sealant applied to the (F69-F-04x02) brass elbow, I finger tightened the elbow onto the (U-01402) lower gear brace and then using a crescent wrench tightened the elbow further about (three quarters to one full turn further) to line up my index marks ensuring a 6.9° offset angle.

*This essentially makes the (U-01402) lower gear braces left and right direction specific now.

It is important not to overtighten these fittings by more than two turns past finger tight.
This area will need to be inspected periodically in the future for hydraulic leaks since the brake lines will be attached to these fittings.


I will probably change these elbow fittings in a later session because I have heard that the standard plastic brake line hoses can leak. There is a better brake line hose system made by Aircraft Specialty Flight Lines, they are a little pricey, I need to research this a little more....Click here to see what the leaking plastic brake lines look like.

Loctite 567

This is the Loctite product that I used. I had to order it on the web because none of the local stores in our area had it in stock.

Trim SV-10 Air Vent

Next, I switched my focus on trimming the (SV-10) NACA fresh air vents. According to steps 5-10, page 29-21 of the builder's manual they each need to be trimmed to final size.
The first step is to trim 3/4" from the forward part of the vent.
I drew a reference line and used a stationary disc sander to remove the material.

Trim Line On SV-10 Air Vents

The next step you have to be careful to how you orient the (SV-10) NACA fresh air vents because 1/4" has to be trimmed from the top of the vent.

*To this point orientation was not important but now you are essentially creating a left and right "direction specific" NACA vent so be careful! You don't want two left or two right vents!

Trimmed SV-10 Air Vents

I marked each (SV-10) NACA fresh air vents being careful to note orientation and using the stationary disc sander trimmed away the extra 1/4" of material.

Remove AN6 Bolts

There are two sets of AN6 bolts that need to be removed at this time so that the (U-01402) lower gear braces can be installed.

(You can see the heads of these bolts in the highlighted section of this photograph.)

The outboard bolts were extracted without much effort but the inboard bolts were a different story....we needed a different strategy because they were not going to come out easy at this point!

These are AN6-46A bolts, and according to Van's Aircraft they are not close tolerance bolts but they sure are acting like they are!


Brass Drift Punches

Van's Aicraft recommended using brass drift punches to help drive the AN6-46A bolts out so I got a set but still was unable to remove the bolts.....something else needed to be done! I'll take a break and think about this for awhile.


Tailcone Plug

I want to make a rotisserie to hold the fuselage and still be able to work on it and not be standing on my head while doing it so today I cut out a "tailcone" plug so that I can mount this to an engine stand in the back, I still have to make a front support to attach the front end to a second engine stand....this is a work in progress so stay tuned!

Cable Links

Step 3, page 33-12 of the builder's manual, instructs that the four (CS-00015) cable links be separated.
These are the cable links, they are used to attach the rudder pedals to the rudder cables.

Separating Cable Links

I separated the (CS-00015) cable links using the bandsaw.

Separating Cable Links

They aren't very big.

Separated Cable Links

They are separated now, next they will have to be deburred and painted.

Fuel Line Brackets

Since I had the bandsaw out I might as well separate the eight (F-01498) fuel line brackets as indicated in step 1, page 31-02 of the builder's manual.

This is what they look like before separation, they are all on one sheet of black plastic like material.

Layout Lines To Separate Fuel Line Brackets

I laid the cutout lines with a silver Sharpie so I could see where to make the cuts.

Separating Fuel Line Brackets

Now for the cuts...

Separated Fuel Line Brackets

There are eight fuel line units. They will need to have the edges filed to further remove the "tabs". The plastic material is super tuff.


Deburred Cable Links

The (CS-00015) cable links are made out of steel so they have to be edge deburred, the holes deburred, and then the surfaces sanded lightly in preparation for priming.

These surfaces have been washed with acetone, the next step priming...

Primed Cable Links

I primed the four (CS-00015) cable links with DupliColor DAP 1690 self etching green primer as indicated in step 2, page 33-12 of the builder's manual.


Painted Cable Links

I painted the four (CS-00015) cable links with DupliColor DA 1600 gloss black acrylic enamel.

*Step 3, page 33-12 of the builder's manual also says to final drill the eight holes in each of the (CS-00015) four cable links, this is to insure that excess primer and paint is removed.


Fuel Line Brackets Final Sized

The eight sets of the (F-01498) fuel line brackets have had all of the edges deburred.


Preparing Brake Pedal Pads For Tread Material

I want to put some wing walk material on the treads of the (CS-00018A) brake pedal pads so I masked off where I want to prepare the surfaces with light sanding before applying the wing walk "brush on" paint.

*I used 320 grit sandpaper here.

Brake Pedal Pads Ready For Tread Material

The four (CS-00018A) brake pedal pads are now ready to apply the wing walk material.

Brake Pedal Pads With Tread Material

I painted the treads with Randolph's X-1567 black wing walk compound.

*I am really disappointed with how this turned out.
I have used Randolph's
wing walk compound in the past with much success.
This was a new can of paint and the texture wasn't near as gritty, nor did the paint self level like it did in my previous experiences so maybe Randolph's changed the formula....who knows....but I am going to sand out what I just did and repaint the treads with something else.

So disappointed with Randolph's X-1567 would not recommend it!


Empennage Transport To Hangar

After several days of windy conditions we finally had a break so we moved the empennage section to our hangar.

We're all loaded up and ready to go!

Empennage At Hangar

Waiting to be joined to the front half!

Empennage Waiting Joining With Front Fuselage

Nice!


Removing AN6 Bolts

Remember those stubborn AN6-46A bolts that needed to be removed in order to install the (U-01402) lower gear braces?

I got to thinking that maybe the top of the center section carry through was spreading ever so slightly that it was pinching the bolts and not letting them to be extracted so I put a clamp on the top of the center section and snugged it up.

That did the "trick", we were able to remove the bolts without much trouble!

I ordered new AN6-46A bolts to replace the ones we took out just for safety though...can't hurt, right?

Left AN6 Bolts Removed

Left side AN6 bolts out.

Right AN6 Bolts Removed

Right side AN6 bolts out.


Clean Up SV-10 Air Vent

There is excess glue that I want to remove from the (SV-10-L and SV-10-R) NACA fresh air vents before I prime them.
You can see the black glue lines here.

Clean Up SV-10 Air Vent

Got to clean up this excess black glue.

Clean Up SV-10 Air Vent

I started on the (SV-10-L) NACA fresh air vent and got the excess glue cleaned up then I sanded the surfaces with 320 grit sand paper, followed with 400 grit sand paper, and then a final scuff with gray ultra fine ScotchBrite pads.


Cleaned Up Excess Glue From NACA Air Vents

Both of the (SV-10-L and SV-10-R) NACA fresh air vents are ready for priming but I still have to wait for the two (SV-6) eyeball vents that I ordered from Van's Aircraft and that UPS lost....it's been 30 days now.

*I need the "eyeball" vents so that I can complete the final assembly instructions found on pages 29-21,22 of the builder's manual.

Rudder Bearing Blocks

In step 1, page 33-05 of the builder's manual, a bearing block template needs to be aligned and clamped to the top of two (F-1039A) bearing blocks so that a #12 hole can be drilled.

These blocks secure the rudder pedal assembly to the sides of the fuselage so the holes have to be accurate and drilled with a drill press.

Rudder Bearing Block Ready For Final Drilling

The bearing block template has been taped into position which was aligned with center marks I drew with a silver Sharpie pen and then everything clamped to the drill press.

I set the drill press depth guide to 1/8" and as a back up put a piece of masking tape on the drill bit for reference and drilled the #12 holes in the tops of the bearing blocks (F-1039A).

Drilling Rudder Bearing Block

Drill away!

*Now I have to wait for a #10 drill bit to arrive to finish drilling the bearing blocks as described in part two of step 1, page 33-05.

The #10 drill bit will be used to drill a #10 hole completely through the block (from the bottom.)

Outboard Flap Bushing

Now I am on page 32-02 of the builder's manual and I laid the cut lines in order to remove excess material in the fabrication of two (F-1030) UHMW outboard bushings.

*I used a silver Sharpie so that the edge lines can be seen.

Inboard Flap Bushing Layout Lines

Back on page 32-02 of the builder's manual and I laid the cut lines in order to remove excess material in the fabrication of two (F-1030) UHMW inboard bushings.

*I used a silver Sharpie so that the edge lines can be seen.
I still have to draw the radius lines yet.

One Inch Radius

One radius is a 1" line drawn with a compass measured from the center of the large hole in the bushing.

Smaller Radii

The remaining two holes have a 3/8" radius drawn around them.


F-14104 Support Angle

According to step 3, page 33-05 in the builder's manual, the (F-6115) rudder pedal bearing block needs to be aligned with the edges of the (F-14104) support angle, which is located under the instrument panel.

*The red arrow shows the support angle that they are talking about, but you can also figure it out by referring to page 33-06 in figure one but also take a look at page 33-01 to get a better idea, it shows a more "zoomed out" view of the angle.

F-14104 Support Angle

Here is a closer view of the (F-14104) support angle.

The edges of the (F-6115) rudder pedal bearing block are supposed to be aligned with the edges of the support angle and then the locations of holes one and four are to be marked so that they can be final drilled using a drill press.

I used some masking tape to hold the (F-6115) bearing block in place while I marked the positions of the holes.

F-6115 Rudder Pedal Bearing Block

This is the (F-6115) rudder pedal bearing block with the one and four hole locations of the (F-14104) support angle that I marked.

*I used a silver "Sharpie" to make the marks easier to see against the black color of the bearing.

I also drew some "witness" marks so that after drilling the block to final size and cutting it in half with a bandsaw it could be reassembled in the original orientation.

Left Lower Landing Gear Brace

We installed the (U-01402) lower gear braces and initially left the nuts loose because Van's only gave us one AN6-46A bolt for each of the foward attach points but there are supposed to be two bolts per side so we had to wait for the bolts to arrive and then we torqued the bolts tight.

*This is a quick build fuselage and the wrong sized bolt that had been installed was the right diameter but the wrong length and we didn't discover this until the time the lower gear braces were installed.

Left Lower Landing Gear Brace

This photograph shows the bolts of the (U-01402) lower gear braces as they protrude throught the wing spar. Both bolts are AN6-46A bolts.

Right Lower Landing Gear Brace

This is the right fuselage side showing the installation of the (U-01402) lower gear brace.

Right Lower Landing Gear Brace

The red arrows show the AN6-46A bolts of the (U-01402) lower landing gear brace as they protrude through the wing spar on the right side of the fuselage.


Final Drilling Bearing Blocks

As I mentioned earlier I had to wait for a #10 drill bit to arrive in the mail and now I finally have it!

As per step 1, page 33-05 of the builder's manual, #10 holes were drilled through the (F-1039A) rudder bearing blocks using the drill press.

I also drilled #10 holes completely through the (F-6115) rudder bearing block using the previously marked holes as guides. (Step 3, page 33-05 of the builder's manual).

The top of the (F-6115) rudder bearing block has a #12 hole drilled 1/8" deep drilled into it also done on the drill press.

Separated Bearing Block

As per step 4, page 33-05 of the builder's manual, the (F-6115) bearing block was cut in half using the bandsaw.

F-1030 UHMW Bushings

As per steps 1 and 2, page 32-02 of the builder's manual, excess material was trimmed from the (F-1030) UHMW inboard and outboard bushings using our bandsaw.

Idler Arms

Since I had the bandsaw out I might as well separate some more parts.

I started out with the (CS-00011) Idler Arms.

Idler Arms

As per step 1, page 36-02 of the builder's manual I drew cutout lines onto the (CS-00011) idler arms as indicated in figure 1 and separated them with the bandsaw.

Separated Idler Arms

Here are the separated (CS-00011) idler arms, I'll debur these later.

Bellcrank Parts

Moving along to the next parts to be separated are the (F-00067) bellcrank, it has to be separated into three parts.

Bellcrank Parts

The two big pieces will be called (F-00067A) and the smaller piece will be called (F-00067D).

Separated Bellcrank parts

As per step 3, page 36-05 of the builder's manual, the three parts have been separated as indicated in figure three using the bandsaw.

*Two (F-00067A's) and one (F-00067D) small spacer.

Bellcrank Spacers

The next item to be separated is the (F-00067BC) bellcrank spacers.

Bellcrank Spacer

These are fairly small spacers so for now I labeled them because they are different. One piece will be (F-00067B) and the other will be (F-00067C).

Separated Bellcrank Spacers

As per step 4, page 36-05 of the builder's manual, I separated the two parts using the bandsaw.

Bellcrank Assembly parts

As per figure 1, page 36-06 of the builder's manual, this is how the individual parts will be laid out to prepare for final drilling but before I do that I want to deburred the edges of the (F-00067A) bellcrank halves.

Cleco Bellcrank Assembly Together

As per step 1, page 36-06 of the builder's manual, I clecoed the (F-00067A), (F-00067B), (F-00067C), (F-00067D), and (VA-146) bearing together as indicated in preparation for final drilling.

Final Drilling Bellcrank Parts

I final drilled the #30 and #12 holes through the bellcrank assembly.

Disassemble Bellcrank Assembly

After final drilling the #30 and #12 holes, everything was disassembled so that I could deburr the edges and holes.

*I marked the position of the (VA-146) bearing so that it would be able to be placed back into the same position before riveting.


Bellcrank Halves

The (F-00067A) bellcrank halves were deburred and then scuffed with ScotchBrite ultrafine gray pads and then washed with acetone in preparation for priming.

Primed Bellcrank Halves

The two (F-00067A) bellcrank halves were primed with Tempo A702 green zinc phosphate primer.

Bellcrank Spacers

The bellcrank spacers (F-00067B, F-00067C, and F-00067D) were deburred and scuffed with the ScotchBrite pad and then washed with acetone in preparation for priming.

Primed Bellcrank Spacers

The bellcrank spacers (F-00067B, F-00067C, and F-00067D) were primed with Tempo A702 zinc phosphate primer.

Bellcrank Mount

The (F-14139) bellcrank mount was the next part to be deburred and scuffed but in addition to that, the #40 holes need to be machine countersunk to accept the head of a AN426AD3 type rivet. This is done so that K1000-3 nutplates can be installed later.

Bellcrank Mount Deburring

I started out by deburring the final sized holes with the hand debur tool.
After deburring the holes I scuffed the surface of the bellcrank mount with a gray ScotchBrite pad.


Countersink Bellcrank Mount

It's time to machine countersink the sixteen #40 holes on the top side of the (F-14139) bellcrank mount where the nutplates will be installed and the AN426AD3-4 rivet heads will set flush.

*Be sure to take note of the orientation of the (F-14139) bellcrank mount as shown in figure 4, on page 36-06 of the builder's manual, because you don't want to countersink the wrong side of the mount!

I like to use our hand debur tool equipped with a #40 countersink bit installed when doing small jobs like this. I made a small drill guide with two #40 holes drilled in it spaced the same distance as the holes are on a nutplate. The drill guide is then clecoed into position so that when I'm using the hand debur tool it keeps the countersink bit oriented 90° to the surface of the part being countersunk. It also helps to eliminate "wobble" as the bit gets deeper into the countersink operation because the nipple on the countersink bit is riding in the deep hole of the guide beneath the surface of the part.

Countersink Guide

Here is what the guide looks like on the back side of the countersink operation.

Countersink Bit

This is the #40 Countersink bit.

Countersinking Bellcrank Mount

Here I am countersinking the sixteen #40 holes into the (F-14139) bellcrank mount.

Bellcrank Ready For Priming

Nice!

I then washed the (F-14139) bellcrank mount with acetone in preparation for priming.

Autopilot Servo Bracket

We are installing an autopilot in our airplane so I ordered the Garmin autopilot servo kit from Van's Aircraft.

This is the (F-14184) autopilot pitch servo bracket that comes with the fuselage kit.

*Don't worry, the (F-14184) autopilot pitch servo bracket is included in the fuselage kit, it is used to mount any autopilot servo.
The Garmin autopilot servo kit has extra parts and electronics specifically used for a Garmin AP servo.

Autopilot Servo Bracket

This is how the (F-14184) autopilot pitch servo bracket will sit when mounted atop of the (F-14139) bellcrank mount (see figure 1, page 36-08 in the builder's manual, or figure 1, page 56-03 of the Garmin autopilot servos instruction sheet).

Deburring Autopilot Servo Bracket

As always the bracket will need to be deburred and there is some modification to be done to the bracket as well.

Our bracket had some tooling marks that had to be removed so make sure that you check the bracket for marks.

Garmin Autopilot Pitch Servo

This is the Garmin autopilot pitch servo and how it will be oriented when attached to the bracket.

Excess Material Guides On Autopilot Servo Bracket

As per step 6, on page 36-06 of the builder's manual, some excess material has to be removed from the (F-14184) autopilot pitch servo bracket.

I marked out the guide line as indicated in figure 3, on page 36-06 so that the excess material can be removed from the bracket using our bandsaw.

There is an option to create an additional lightening hole in the bracket if you want, I have chosen to add a 3/4" hole, 1 1/4" seems to be too big for my comfort zone!

Removing Excess Material From Bracket

I removed the excess material with the bandsaw.

Removing Excess Material From Servo Bracket

I had to use some support blocks to keep the bracket side tab from scraping the table on the bandsaw.

Autopilot Servo Bracket

Here is what it looks like with the excess material removed, I still have to final drill all of the holes and add a 3/4" lightening hole and then debur everything.


Autopilot Servo Bracket Cleanup

I deburred all of the edges, and final drilled the #10 holes that the AN3-4A bolts used to attach the servo to the (F-14184) autopilot servo bracket with and deburred them.

A 3/4" lightening hole was added to the bracket and then deburred. The surfaces were scuffed with a gray ScotchBrite pad and then washed with acetone in preparation for priming.

*Don't forget to get the tooling marks out, they definitely need to be removed with some sandpaper.

Autopilot Ready For Priming

Ready for priming!

Deburring Idler Arms

The (CS-00011) idler arms where edge deburred and the surfaces scuffed with a gray ScotchBrite pad.

All of the holes were final sized and deburred as well. The parts were washed in acetone in preparation for priming.


Priming Parts

The (F-14184) autopilot pitch servo bracket was primed with Tempo A702 green primer.

Primed Autopilot Servo Bracket

Primed Idler Arms

The two (CS-00011) idler arms were primed with DupliColor DAP1690 green primer.

*Some have asked, why two types of primer? The answer is simply that I want all of the parts in the aft empennage to match the green color of the Tempo A702 that I originally used from the beginning of the project. All of the parts forward of the bulkheads will recieve DupliColor DAP1690 since I like using that primer better and they won't be seen.

Cleco Bellcrank Assembly For Riveting

As per step 3, on page 36-06 of the builder's manual, all of the parts for bellcrank assembly are to be clecoed together and then riveted.

The parts are: (F-00067A, F-00067B, F-00067C, F-00067D, and VA-146).

Bellcrank Assembly

Everything is ready to go but the AN6-46A bolts have arrived for the final installation of the (U-01402) lower gear braces so I'm off to the hangar to install them.


Lower Gear Brace

The front AN6-46A bolts have been installed on the (U-01402) lower gear braces and final torqued according to the values published on page 5-18 of the builder's manual and adjusted for friction drag. *I used 14 foot/pounds for the front two bolts and applied torque seal.

The aft two AN5-10A bolts installed were final torqued according to the values published on page 5-18 of the builder's manual and adjusted for friction drag. *I used 144 inch/pounds for the aft two bolts and applied torque seal.

Lower Gear Brace

These are the installed and torque sealed bolts for the right side (U-01402) lower gear brace.


Rivet install for QBF-2

As per QBF fuselage instructions page QBF-2, step 4, there are four holes that were left open for cover plates (they assumed that this was to be a "tail dragger"....all QB kits are made this way), but since this is a tricycle geared aircraft, the holes now have to be filled with AN426AD3-3.5 rivets.

*The holes that the plans are referring to are found in figure 1, page 26-14 of the builder's manual.
The two holes can be seen in this photograph, they are the top two holes just forward of the horizontal rib.

Rivet Install for QBF-2

This is another view of the two holes that need to be riveted. They are the two holes shown aft of the horizontal rib in this photograph.

We were able to set two of the four rivets but because there is a seam along the edge of one of the holes we need to get a small flat set for our 3x rivet gun in order to clear the seam and still set the remaining two rivets.

Aft Fuselage Attachment To Forward Fuselage

Now for the exciting part! We are ready to cleco the aft fuselage assembly to the forward fuselage assembly.

First we aligned the two assemblies close to each other as described in steps 1-3, page 30-03 of the builder's manual.

In step 4, you have to lift the aft fuselage slightly higher than the front, as seen here, in order to get everything aligned.

Aft Fuselage Attachment To Forward Fuselage

In steps 5-13, on page 30-03 of the builder's manual the tail then has to be elevated so that the forward section pivots in a downward fashion and then you just start clecoing everything into position!

*Looking back it did take a few "read throughs" of the directions but in reality everything went together fairly easily, you just have to constantly watch the two long "arms" in the front of the empennage section so they don't move to the inside of the front fuselage.

Aft Fuselage Attachment To Forward Fuselage

Here is what it looks like on the inside.

Aft Fuselage Attachment To Forward Fuselage

Another view of the inside intersection of the two halves.

Aft Fuselage Attachment To Forward Fuselage

The baggage bin bulkheads, shoulder harness lugs, and the ELT antenna bracket are the next items to be clecoed into position as described in steps 1-5, on page 30-04, steps 1-2, page 30-05, and steps 5-6, page 30-06 of the builder's manual.

Aft Fuselage Attachment To Forward Fuselage

Here it is all ready to be riveted together!

*There are some areas that do not get riveted right away so they will have to be marked and there is a certain order to do the riveting so take note of these.


Bellcrank Riveting Together

Back to the bellcrank assembly, it needs to be riveted together as directed in step 3, on page 36-06 figure 1 of the builder's manual.

I used our pneumatic squeezer to rivet everything together.
I substituted AN470AD4-6.5 rivets for the AN470AD4-6 rivets called for in the plans....the 4-6 rivets seemed a little too short.

Bellcrank Assembled

Here it is!

Bellcrank Assembled

Nice!

Drill Bellcrank Angles

#12 holes were final drilled and deburred in the two (F-1037A) bellcrank angles as per step 4, on page 36-06 of the builder's manual. (There are eight holes to be final sized.)

Attach Bellcrank Assembly To Bellcrank Angles

As per step 5, 0n page 36-06 of the builder's manual, the elevator bellcrank assembly was aligned between the two (F-1037A) bellcrank angles making sure that the longer portion of the bellcrank assembly was "pointing" up. Using the hardware called for in figure 2, on page 36-06, the parts were attached to one another.

*Be sure not to final torque the MS21042-4 locking nut yet because when this assembly is mounted to the (F-14139) bellcrank mount it is easier and lays flatter when the parts have freedom to move.

Bellcrank Assembly

Install Nutplates To Bellcrank Mount

Eight K1000-3 nutplates were attached to the (F-14139) bellcrank mount using the pneumatic squeezer. I used AN426AD3-4 rivets here, again, the AN426AD3-3.5 rivets called for in figure 4, on page 36-06 seemed too short.

Nutplates Installed

Nutplates Installed!

Nutplates Installed

Bellcrank Assembly Installed to Bellcrank Mount

These are the bolts and washers needed to install the bellcrank assembly to the bellcrank mount (F-14139).

*These are AN3-4A bolts as per figure 1, on page 36-07 of the builder's manual.

Bellcrank Assembly Installed Onto Bellcrank Mount

*Note that the washers are placed under the head of the AN3-4A bolt.

Bellcrank Assembly Installed Onto Bellcrank Mount

Final Torque Bellcrank Nut

Now is a good time to final torque the MS21042-4 locking nut. I torqued the nut according to the values published on page 5-18 of the builder's manual and adjusted for friction drag.
*I used 99 inch/pounds. There were 5 threads showing which is allowed according to page 5-18 of the builder's manual.

Sanded Brake Pedal Treads

As I mentioned earlier in this section, I was not happy with the way that the treads looked on the four (CS-00018A) brake pedal pads so I sanded the Randolph's Wingwalk Compound off with 320 grit sandpaper so that they could be repainted with truck liner paint.


Brake Pedal Treads Waiting For Paint

After sanding the four (CS-00018A) brake pedal pads, I washed them with alcohol in preparation for paint.

The temperatures are too hot to paint anything in the afternoon here so I have to wait until early morning to paint the treads.

Wood Plugs

I laid out four wood plugs so that I can cap off the ends of the aileron torque tubes so that primer can be "sloshed" around the inside of the tubes. They need to be primered soon.

Wood Plugs

I bevel ground the four plugs on the disc sander for the upcoming torque tube priming session....hope they work!

Air Vent Assembly

Back to airplane parts!
These are the air vent assembly parts that need to be clamped together as per step 11, on page 29-21 of the builder's manual. Some of the parts need excess material removed and there are some holes to drill.

The parts are: SV-10 vents, SV-6 flo vents, and F-14186 vent brackets.

Air Vent Assembly

First, all the parts were clamped together with spring clamps as shown in figure 4, page 29-21 of the builder's manual.

*Be sure to keep the parts oriented correctly, remember there are right hand and left hand parts here!

Match Drill Air Vent Holes

Using the #40 holes in the (F-14186) vent bracket as guides, I match drilled #40 holes into the (SV-10) NACA fresh air vent clecoing each hole as the drilling progressed.

Match Drill Air Vent Holes

After the #40 holes were drilled, they needed to be enlarged to 9/64" as indicated in step 3, page 29-22 of the builder's manual. I enlarged each hole, one at a time, through the (F-14186 vent bracket, SV-6 flo vent, and SV-10 NACA vent) but reclamped everything with the spring clamps and then used a 1/8" cleco in each hole as the drilling progressed.

*The 1/8" cleco will hold but it is not tight so don't rely heavily on their holding power at this point.

After drilling the 9/64" holes, I outlined the border line of the (F-14186) vent bracket onto the (SV-6) flo vent so that excess material can be removed by the bandsaw as per step 4 and figure 2, on page 29-22 of the builder's manual.

Trimming SV-6 Flo Vents

The (SV-6) flo vents are thick aluminum and need to be trimmed on the bandsaw.

Trimmed SV-6 Flo Vent

I cut close to the line but will final size the flo vent with a file...they are expen$ive and I don't want to mess anything up!


Painted Brake Pedal Pad Treads

This morning it's cool enough to paint so I painted the four (CS-00018A) brake pedal pads with DupliColor BAA2010 Bed Armor paint. They turned out great!

Trimming SV-6 Flo Vents

After final trimming the (SV-6) flo vents I sanded the forward sides with 100 grit aluminum oxide sandpaper because these sides will eventually be adhered to the (SV-10) NACA air vents with silicone adhesive.

Trimmed SV-6 Flo Vents

This is what the front sides of the (SV-6) flo vents look like after final trimming.

Everything has to be reclamped together because the outlines of the (SV-6) flo vents have to drawn onto the (SV-10) NACA vents so that they can have excess material removed from them as per step 4, figure 2, on page 29-22 of the builder's manual.

Trimmed SV-10 NACA Vents

I used a stationary disc sander to trim the (SV-10) NACA vents to their final size.

Trimmed F-1030 UHMW Bushings

Since I had the stationary disc sander out I final sized the (F-1030) UHMW inboard and outboard bushings.


Primed Air Flow Vent Brackets

I washed the (F-14186-L and F-14186-R) NACA vent brackets with acetone in preparation for priming.
The surfaces of the vents that should not be painted were masked off because they will eventually be adhered to the fuselage side skins with adhesive.

The vents were primed with DupliColor DAP1690 self etching green primer.

Primed NACA Air Vents

The (SV-10-L and SV-10-R) NACA fresh air vents were washed with alcohol and then masked off in preparation for priming.
These NACA vents will be adhered to the fuselage side skins and also the (SV-6-L and SV-6-R) flo vents with adhesive and that is why they need to be masked off.

The vents were primed with Krylon MAXX 9188 primer.

*Be careful not to wash any plastic parts with acetone, it will harm the plastic.


Assembling Rudder Pedals

As per step 7, page 33-03 of the builder's manual, the (CS-00018A) brake pedal pads, (CS-00018B) "C" channels, and (F-1052B) brake pedal side plates need to be clecoed together for riveting.

*Be careful to pay attention to the orientation of the parts and refer to figure 2, on page 33-03 to help you out because there are right and left pedals being created here!

Assembling Rudder Pedals

All clecoed up and ready for riveting.

*There are several different rivet call outs here so be careful.

Pneumatic Squeezer Set Up For Rudder Pedal Riveting

I am using our pneumatic squeezer to set the rivets in the rudder pedal assembly. I have a shallow 1/8" cupped set installed on the ram side of the squeezer and a mid sized flat set installed on the 4" squeezer yoke.

Riveting Rudder Pedals Together

Here I am riveting the pieces together with the pneumatic squeezer using the rivet callouts described in figure 2, on page 33-03 of the builder's manual.

Rivets that will be used are: AN470AD4-8, AN470AD4-7, and AN470AD4-6.

Riveted Rudder Pedals

First phase of the rudder pedal assembly is done, next comes the "Z" channel installation.

Riveting Z Channels To Rudder Pedals

The (CS-00018C) brake pedal "Z" channels were clecoed to the rudder pedal assemblies.

The top and bottom edges of the "Z" channels will have AN470AD4-6 rivets set with our pneumatic squeezer, but the middle holes will recieve LP4-3 rivets that will be set with our CherryMax G-27 hand rivet gun.

Rudder pedals Completed

All of the rivets have been set, the rudder pedals are complete!

Rudder Pedals Completed

Priming Elevator Pushrods

The elevator pushrods (CS-00001, CS-00002, and CS-00003) have had the ends deburred and are ready to have the insides primed. The ends have the wooden plugs installed and ducted taped to help manage the messy priming process.

Priming Elevator Pushrods

This is what the wood plug looks like before the duct tape appication.

Priming Elevator Pushrods

The inside walls of the pushrods were primed with PTI camouflage gray zinc phosphate primer using the slosh method. Just pour some paint down the inside of the pushrod and shake! *It's pretty messy!

Priming Elevator Pushrods

I hung the pushrods vertically and let them drip dry into a baking pan.

Priming Elevator Pushrods

After the primer dried in the elevator mid pushrods (CS-00002 and CS-00001) they were scuffed with red ScotchBrite pads in preparation for priming.

Priming Elevator Pushrods


Aft Elevator Pushrods

I deburred the ends of the (CS-00003) aft elevator pushrod as per step 1, page 36-04 of the builder's manual and then scuffed the surfaces with red ScotchBrite pads to make things a little easier later when it comes time to prime the pushrod.

Pushrod End Alignment Template

I reproduced the forward, mid, and aft pushrod drill templates found on page 36-17, of the builder's manual out of manilla folder material so that I wouldn't have to reuse the cutout from the manual over and over again. It saved some time because I could just tape the template on the pushrod ends and not have to worry about being careful to tape and then un-tape the template as the center punching process progressed.

*Be sure to double check the accuracy of the printed scale on the page for your dimensions before you use the templates.

Template Secured To CS-00001

As per step 1, on page 36-03 of the builder's manual, I aligned the pushrod drill template with the ends of the (CS-00001) forward elevator pushrod and then secured it with clear tape.

Template Secured To CS-00002

I did the same thing with the (CS-00002) mid elevator pushrod.

Template Secured To CS-00003

Yep, the (CS-00003) aft elevator pushrod got the drill template secured to it's ends as well!

Center Punch Pilot Holes

With six pushrod drill templates taped to the ends of all of the elevator pushrods it was a simple matter to center punch the "crosshairs" in a timely fashion.

There are six holes per end that need to be center punched. (36 holes in all.)


Aft Elevator Pushrod Paint Stand

On a side project, I was wondering how I was going to prime the outside of the (CS-00003) aft elevator pushrod so I built this simple stand so that the pushrod could be painted without having to move it around much...Happy Festivus!

Center Punched CS-00001

All of the crosshairs have been center punched.

Drilling Pilot Holes Into Elevator Pushrods

As per steps 2-5, on page 36-03 of the builder's manual, #40 pilot holes were drilled into each of the ends of the (CS-00001 and CS-00002) elevator pushrods, making sure to keep the drill lined up with the "crosshairs" of the drilling template.

Template Drill Or Center punch Drilling

On the onset I debated whether to leave the template in place as I drilled the pilot holes, so I took the template off and just used the center punch holes as guides on the first set of holes.
I quickly decided that it was much easier to see where I was drilling if I left the templates in place plus the tape and paper of the template kept my drill bit from wandering so for the rest of the pilot hole drilling step, I just left the templates attached.

#40 Pilot Holes

The holes are all drilled for the (CS-00001 and CS-00002) elevator pushrods.

All of the holes and edges were deburred after drilling.

Drilling CS-00003 Pilot Holes

Now time to drill the (CS-00003) aft elevator pushrod.

#40 Pilot Holes In CS-00003

As per step 3, on page 36-04 of the builder's manual, six #40 pilot holes were drilled into the ends of the (CS-00003) aft elevator pushrod.


Elevator Pushrod Ends

Each of the elevator pushrods will receive a rod end fitting which is supposed to be inserted into the ends of the pushrod and have six #30 holes drilled into them; before I do that I want to debur each one and scuff the surfaces so that they can be primed later.

There are four (CS-00016) rod end fittings and two (VA-101) rod end fittings. These are the four (CS-00016) rod end fittings. They will be attached to the (CS-00001 and CS-00002) foward and mid elevator pushrods which are 1" in diameter.

CS-00003 Elevator Pushrod Ends

After the deburring and scuffing process was done I used a sharpie to mark reference lines on the rod end fittings where the elevator pushrod end should line up with the fitting.

*Step 3 and figure 2, on page 36-03 of the builder's manual, show that the proper engagement is when the end of the pushrod coincides with the edge of the taper in the rod end fitting (which is 1/2").

Index Marks On Elevator Pushrod Ends

These are the (VA-101) rod end fittings that will be placed at the ends of the (CS-00003) aft elevator pushrod, which is 1 1/2" in diameter. I deburred and scuffed these also.

Elevator Pushrod Ends Index Marked

The rod end fittings have been deburred and scuffed and I have the reference lines marked on each so that it will be easier to keep proper alignment during the match drilling operation.

Elevator Pushrod End Alignment

According to figure 2, on page 36-03 and figure 2, on page 36-04 of the builder's manual, this is what the proper alignment should look like. The taper of the rod end fitting coincides with the end of the elevator pushrod.

Now it's time to match drill #30 holes into the rod end fittings using the previously drilled #40 holes as guides.

Cleco After Drilling Pilot Hole Upsizing

Clecos were inserted into each new hole as the drilling progressed around the circumference of the pushrod.

Clecoed Pushrod Ends

I used a tube cutting jig clamped to the table to help support the pieces as I match drilled the #30 holes.

Six Clecoed Pushrod Ends

Six holes drilled, 30 more to go!

Six Pushrod Ends Clecoed On CS-00002

Match Drilled Elevator Pushrod Ends

All of the elevator pushrods and rod end fittings have the #30 holes match drilled now.

*Don't forget to mark the ends of the pushrods and the rod end fittings so that everything can be diassembled, deburred, and reassembled in the correct order!

After I disassembled all of the parts and deburred everything, I washed all of the parts with acetone in preparation for priming.


Priming Elevator Pushrods

This morning I am priming the (CS-00001, CS-00002, CS-00003) elevator pushrods and the (CS-00016 and VA-101) rod end fittings with DupliColor DAP 1690 self etching green primer.

Primed Elevator Pushrods

Nice!


Stick Link Pushrod

This is the (CS-00004) stick link pushrod. It connects the two (CS-00007-L and CS-00007-R) flight sticks together which is described later in step 1, on page 36-12 of the builder's manual.

For now it needs to be deburred and scuffed so that it can be primed.

Stick Link Pushrod

The (CS-00004) stick link pushrod was deburred and the surfaces scuffed with a red ScotchBrite pad in preparation for priming as per step 3, on page 36-02 of the builder's manual.

Stick Link Pushrod Hardware

This is the hardware called out to be attached to the stick link pushrod assembly.

Figure 3, on page 36-02 of the builder's manual shows the hardware to be used. The parts are: (2)-AN316-4R jamb nuts, and (2)-M3414M rod end bearings.
I had to attach these so that I could hold them while I was priming the pushrod. They will have to be properly adjusted and tightened later.

Stick Link Pushrod

The (CS-00004) stick link pushrod was washed with acetone in preparation for priming.


Primed Stick Link Pushrod

I primed the (CS-00004) stick link pushrod with DupliColor DAP 1690 self etching green primer.


MSP-42 Rivets

The hardware callout in figure three, page 36-03 says that the (CS-00001) forward elevator pushrod, (CS-00002) mid elevator pushrod, and the (CS-00003) aft elevator pushrod need to be assembled using MSP-42 rivets, depending which bag you pull them from this is what they look like.

Elevator Pushrods Clecoed For Assembly

I clecoed the rod end fittings onto the ends of each elevator pushrod making sure to match the previously marked end to it's corresponding torque tube.

(CS-00001 and CS-00002) forward and mid elevator pushrods each receive (CS-00016) rod end fittings while the aft elevator pushrod (CS-00003) receives a (VA-101) rod end fitting.

CS-00001 Assembly

This is the forward elevator pushrod (CS-00001) ready to receive attachment of the (CS-00016) rod end fitting.

*You can see the markings I used so that when I reassembled the piece after priming I could put everything back in the right order.

Setting MSP-42 Rivets

I used our CherryMax G-27 hand rivet gun to set the MSP-42 rivets.

Foward Elevator Pushrod

Two rivets set, 34 more to go! Each end receives six rivets.

Foward Elevator Pushrod End Assembly

Nice!

All Elevator Pushrod Ends Attached

The rod end fittings have been attached to each of the three elevator pushrods (CS-00001, CS-00002, and CS-00003).

Install Pushrod Rod End Bearings

The rod end bearings are next to be installed onto each of the elevator pushrods. There are two jam nuts and two rod end bearings per pushrod to be assembled; the hardware callouts are shown in figure 3, page 36-03 for the forward and mid elevator pushrods and in figure 3, page 36-04 for the aft elevator pushrod.

Basically, the (CS-00001) forward elevator pushrod and the (CS-00002) mid elevator pushrod receive two AN316-4R jam nuts and two M3414M rod end bearings each. The (CS-00003) aft elevator pushrod receives two AN316-6R jam nuts and two MD3616M end bearings.

*Be sure to take note of the warning that states that "in the final installation both pushrod ends must have over half of the threads engaged making it impossible for a bearing to back off the pushrod if both ends are pinned."

CS-00001 Forward Elevator Pushrod  Length

Once the jam nuts and the rod end bearings have been installed, the overall lengths must be adjusted.
Figure 4, page 36-03 of the builder's manual shows the bearing-to-center bearing lengths that each of the forward and mid elevator pushrods should theoretically be.

This is the (CS-00001) forward elevator pushrod and I adjusted it so that it had a bearing-to-center bearing length of 31 11/16". I tightened the jam nut, for now, only finger tight because most likely there will be further adjustments needed upon actual installment at which time the jam nut will be torqued and safety sealed into place.

*Keep in mind that as you adjust the pushrods to their final length you must adjust each end evenly until final length is achieved.

CS-00002 Mid Elevator Pushrod Length

This is the (CS-00002) mid elevator pushrod and I adjusted it to a bearing-to-bearing center length of 44 15/16" with the jam nut tightened only finger tight until final installation at which time it will be final torqued and safety sealed.

CS-00003 Aft Elevator Pushrod Bearing End Installment

The (CS-00003) aft elevator pushrod receives two AN316-6R jam nuts and two MD3616M rod end bearings as called for referencing figure 4, page 36-04 of the builder's manual.

*The same note warning that "in the final installation both pushrod ends must have over half of the threads engaged making it impossible for a bearing to back off the pushrod if both ends are pinned applies here too."

CS-00003 Aft Elevator Pushrod Length Adjustment

According to the dimensions given in figure 4, page 36-04 of the builder's manual, the bearing-to-bearing center length should theoretically be 72 29/32" so I adjusted it accordingly and then finger tightened the jam nut in place.

*The jam nut will be final torqued and sealed after final installation.

Elevator Pushrod Installed And Length Adjusted

All of the elevator pushrods have their jam nuts and rod end bearings installed and have been adjusted for proper length.

Stick Link Pushrod Assembly CS-00004

The stick link pushrod assembly (CS-00004) connects the two flight control sticks together and is assembled in a somewhat similar fashion as the elevator pushrods.
In step 4, page 36-02 of the builder's manual, the assembly process begins. Figure three gives the hardware callouts which consist of two AN316-4R jam nuts and two M3414M rod end bearings.

The bearing-to-bearing center length was adjusted to 21 1/2" according to the measurements given on the same page. The jam nuts were tightened finger tight but will be final torqued and sealed when installed.

Fabricating Autopilot Pushrod Tubes

We are installing an autopilot on our RV14A and I ordered the optional Garmin autopilot servo install kit from Van's Aircraft. Step one, on page 56-02 of the builder's manual instructs that two pushrods and one roll standoff be fabricated from a (AT6-058x5/16) aluminum tube.

AP Pushrods Cut To Length

The two push rods created are 3 1/4" in length and will be labled (CS-00017) for the pitch control rod, (CS-00019) for the roll control rod, and (CS-00020) for the roll servo standoff, (which is 15/32" long).
I cut these out using the bandsaw and then squared the ends using a stationary disc sander. The ends were deburred as well.

Drilling The Autopilot Pushrods

Now the fun begins...

Figure one, page 56-02 of the builder's manual, gives additional information in the construction of the two (CS-00017 and CS-00019) autopilot pitch and roll pushrods.
A #3 hole is to be drilled through the center of each end of each tube to a depth of 1 1/4". Obviously this needs to be centered as much as possible so I constructed a simple jig by drilling a 5/8" hole in a scrap piece of 2"x4" lumber with the drill press in order to hold the tube vertically. This made it easy to keep the tube centered while drilling the #3 hole down the center of the tube with our drill press.

*Make sure you don't drill the 5/8" hole all the way through the 2"x4" wood because you need the tube to be able to rest on the bottom flat area of the wood, plus the extra friction helps keep the tube from spinning as the #3 hole is being drilled in the tube.

1/4x28 Tap

After the 1 1/4" #3 hole has been drilled in both ends of the tubes they need to be threaded using a 1/4-28 tap to a depth of 1 inch.

Hand Tap Set

I will be using a hand set and this 1/4-28 tap to thread both ends of the (CS-00017 and CS-00019) autopilot pitch and roll servo pushrods.


Hand Tapping AP Servo Pushrods

It takes awhile to thread these autopilot pitch and roll servo pushrods, don't forget to use some cutting oil to help the process.

Threaded AP Servo Pushrods

One end threaded three more to go...

Preparing AP Servo Pushrods For Priming

After the tapping process was finished I soaked the parts in acetone to get any residual oil off then scuffed, sanded, and deburred everything and rewashed the parts in acetone in preparation for priming.

Primed AP Servo Parts

I primed the (CS-00017 and CS-00019) autopilot pitch and roll servo pushrods with DupliColor DAP1690 self etching green primer.

Primed AP Servo Parts

I primed the (CS-00020) roll servo standoff with Duplicolor DAP 1690 self etching green primer.

Painted AP Servo Parts

I painted the (CS-00017, CS-00019, and CS-00020) elevator pitch servo, aileron roll servo, and roll servo standoff with Duplicolor DA 1600 gloss black acrylic enamel.


Wrong Bearings

I was going to final assemble the autopilot pitch and roll servo pushrods but Van's sent the wrong rod end bearings with the install kit.
These are four MD3616M bearings but they are supposed to be MD3414M bearings. I called them up and the switch is in progress....


Baggage Bin Floor

I started the debur process on the right baggage bin floor (F-01447-R). Time to peel off all the protective blue vinyl.

Baggage Bin Floor

The baggage bin floors are part of section 32 of the builder's manual.

Baggage Bin Floor

I'm deburring the edges of the right baggage bin floor (F-01447-R) using mostly a flat file at this point....


CS-00017 Rod End Bearings

Figure two, on page 56-02 of the builder's manual, shows the hardware needed to complete the assembly of the (CS-00017) auto pilot pitch servo pushrod assembly.

There are two (AN316-4R) jam nuts and two (M3414M) rod end bearings that need to be installed.

Adjusting CS-00017 Length

After the (AN316-4R) jam nuts and the (MD3414M) rod end bearings were installed, the center-to-bearing-center length of the (CS-00017) auto pilot pitch servo pushrod was adjusted to 4 7/8" long.
Final adjustments will be made once installed onto the airplane and the jam nuts will be final torqued.

AN257-P3 Hinge

Seatback hinges need to be fabricated and referencing figure two, page 32-03 of the bulder's manual, they need to be fabricated from a six foot length of (AN257-P3) hinge.

AN257-P3 Hinge

Here's a closer look at the (AN257-P3) hinge.

Remove AN257-P3 Hinge Pin

As per step three, on page 32-02 of the builder's manual, the center hinge pin was removed.

F-01447B Seatback Hinges

Six (F-01447B) seatback hinges need to be fabricated from this hinge material. Each hinge needs to be 10 1/2" long.

*There is a cautionary note at the top of page 32-03 that says to be sure that when cutting lengths of (F-01447B) seatback hinges from the (AN257-P3) hinge material to allow enough material to fabricate the seat hinges in section 39.

As long as you are careful, there are only two 10 1/2" long seatback hinges (F-1237H) that will be cut from this hinge stock, the other hinges that will need to be made use a different (AN257-P2) hinge.

Cutting F-01447B Seatback Hinges

The hinge stock is too long to cut with my bandsaw so I had to go the "old fashioned" way and make the initial cuts with a hacksaw....haha!

Cutting F-01447B Seatback Hinges

It's not too bad...

Cutting F-01447B Seatback Hinges

I'll make the cuts a little closer to the lines on the bandsaw next.

Cutting F-01447B Seatback Hinges

Just a bit closer and then I'll "fine tune" the cuts later with our stationary disc sander.

F-01447B Seatback Hinges Cut

Six (F-0147B) seatback hinges cut to size, still have to final size them using the stationary disc sander and there are two center "eyelets" that need to removed from these.

F-1237H Seatback Hinges Cut

Since I have the bandsaw out, I might as well cut the two (F-1237H) seatback hinges as per step five, figure four, of page 39-02 of the builder's manual.
These are 10 1/2" long and are fabricated from the same (AN257-P3) hinge material.

F-01447B Seatback Hinges Eyelet Removal

Time to start cutting out the center "eyelets" too.

F-01447B Seatback Hinges Eyelets Removal

These are the two center "eyelets" of the (F-01447B) seatback hinges that need to be removed as per step four of page 32-03 of the builder's manual.

F-01447B Seatback Hinges Eyelets Removed

The center "eyelets" have been removed, now everything has to be final sized and deburred.

F-01447B Seatback Hinges Deburred

Six deburred (f-01447B) seatback hinges!


Draw Center Line On F-01447B Seatback Hinges

I drew a line along the lengths of each of each of the six (F-01447B) seatback hinges as per instructions in step five, page 32-03.

*The line is supposed to be drawn on the flush side of each hinge.

Locating Hole For F-01447B Seatback Hinges

A #30 locating hole is supposed to be drilled into each of the six (F-01447B) seatback hinges.
This hole is supposed to be 1/4" from the end and 1/4" from the top edge of the (F-01447B) seatback hinge.

*The small "tick" mark is the 1/4" by 1/4" mark from the edge but I found that if I lined up all of the (F-01447B) seatback hinges and then aligned the mating half of the hinge, (F-1237H) the part that attaches to the back of the seat backrest, it matches the alignment of all of the "eyelets" better if I measured 1/4" from the square of the "eyelet" so that's why there is a larger "tick" mark that I will be using for my drill centerpoint.
Remember, this is what I did, doesn't mean you should do the same!

F-01447B Seatback Hinges Locating Holes Drilled

All of the #30 locating holes have been drilled into each of the six (F-01447B) seatback hinges.

Mark Center Eyelet On F-1237H Seatback Hinge

The center "eyelets" of the two (F-1237H) seatback hinges have been marked so that they can be removed on the bandsaw.


Seatback Hinge

As per step five, on page 39-02 of the builder's manual, the center "eyelet" of the (F-1237H) seatback hinge was removed from the hinge using our bandsaw.

It's kinda of rough so it needs to be filed smooth and deburred.

Seatback Hinge

The (F-1237H) seatback hinge has the "eyelet" cutout filed and deburred and now according to step six, on page 39-02 the end needs to have a #30 drill guide hole marked and drilled.

Seatback Hinge

I drilled the #30 guide holes in the two (F-1237H) seatback hinges with our drill press and deburred the holes.

Autopilot Roll Servo Pushrod

In step three, page 56-02 of the builder's manual, the (CS-00019) autopilot roll servo needs to be assembled.

There are five parts that go into the assembly: the servo pushrod tube, two (AN316-4R) jam nuts, and two (M3414M) rod end bearings.

Autopilot Roll Servo Pushrod

The center-to-center bearing length of the (CS-00019) autopilot roll servo pushrod needs to be adjusted to a length of five inches.

I set the length to five inches for now but there may need to be some final adjustments made once the assembly is installed and the jam nuts will be final torqued and marked with torque seal.

*The two nuts need to be torqued to a value between 14-20 inch/pounds.

Autopilot Roll Servo Pushrod

I labled the (CS-00019) autopilot roll servo pushrod with the number "19".


Marking No Rivet Zones In Fuselage

There are several holes that do not get riveted yet in the fuselage joining process.

In step four, figure three, on page 30-06 of the builder's manual, there are five sections that need to be taped over so they aren't accidentally riveted.

*I marked them with the black electrician's tape that you see in this photograph.

Marking No Rivet Zones In Fuselage

There are additional holes that need to be marked on the sides of the fuselage so they don't accidentally get riveted yet. I taped over them as per step two, figure one, on page 30-07 of the builder's manual.

*The "hatched area" illustrated in figure one was marked with the black electrician's tape.


Left Floor Skin

Back to working on the baggage bin floor skins.

As usual the first step is to peel off the protective blue vinyl and start the edge deburr process.

Peel Off The Vinyl

Off comes the vinyl!

Left Baggage Bin Floor Skin

Nice and shiny!

Deburring The Floor Skin

It is easier for me to place the piece on it's side when doing the edge debur process.

This is the left (F-01447-L) baggage bin floor skin.

After I get done with the edge deburring I'll final ream and deburr all of the #30 and #40 holes.


Yaw Damper Servo Mount Kit Inventory

I just received the optional (14 G3X Yaw Servo Install Kit) yaw damper servo mount kit from Van's Aircraft. I am not sure if I will actually put a yaw damper servo in at this time but I wanted to at least have the mount in place just in case I want to install one later.

It is easier to install the yaw servo mount now than wait to install it later.

Yaw Damper Servo Mount Kit

Here are all of the parts in the (14 G3X Yaw Servo Install Kit).

Parts of this mount gets installed under the pitch servo mount so if I wanted to install this later I would have to uninstall the pitch servo mount, fit this into place, and then reassemble everything....what a mess that would be!


Locating The Seatback Hinges

The (F-01447B) seatback hinges were clecoed to the (F-01447-L and F-01447-R) baggage bin floors individually.

I used a piece of duck tape to hold the hinge over the center of the pre-punched holes in the floor skins.

Locating The Seatback Hinges

*Make sure that the centerline that was previously drawn down the center of the (F-01447B) seatback hinge remains in the center of the pre-punched holes in the floor skins before moving on to the match drilling process.

Match Drilling The Seatback Hinges

As per step two, on page 32-04 of the builder's manual, #30 holes were match drilled into the (F-01447B) seatback hinges.

The holes were all deburred after drilling.

Match Drilling The Seatback Hinges

One more row to go on this skin...

Match Drilling The Seatback Hinges

The #30 holes in the (F-01447B) seatback hinges have been matched drilled in the right (F-01447-R) baggage bin floor skin.

Match Drilling The Seatback Hinges

The #30 holes in the (F-01447B) seatback hinges have been match drilled in the left (F-01447-L) baggage bin floor skin.

Seatback Hinge Preparation For Priming

I scuffed each (F-01447B) seatback hinge with a red ScotchBrite pad, washed it with acetone, and marked it (so it could be placed back into it's original position) in preparation for priming.

Title

I scuffed the individual holes on the bottom side of the (F-01447-R) right baggage bin floor in preparation for priming after the dimpling process is done.


Primed The Seatback Hinges

The six (F-01447B) seatback hinges were primed with DupliColor DAP 1690 self etching green primer.

Primed Seatback Hinges
Preparation Of Floor For Priming

I finished scuffing around the holes on the bottom side of the (F-01447-R) baggage bin floor, they will be primed later.

Preparation Of Floor For Priming

I scuffed the top surface of the (F-01447-R) baggage bin floor which will be primed later after installation.

Preparation Of Floor For Priming

I scuffed the top surface and around the holes on the bottom side of the (F-01447-L) baggage bin floor.


Riveted Two Open Holes In Fuselage Bottom

As per step four, on page QBF-2 of the Quick Build instructions, the two remaining open holes referenced in figure one, on page 26-14 of the builder's manual, were riveted with two AN426AD3-3.5 rivets.

This is the right side of the fuselage.

Riveted Two Open Holes In Fuselage Bottom

As per step four, on page QBF-2 of the Quick Build instructions, the two remaining open holes referenced in figure one, on page 26-14 of the builder's manual, were riveted with two AN426AD3-3.5 rivets.

This is the left side of the fuselage.

Riveting Shoulder Harness Lug Assembly

As per step six, on page 30-06, figure two, of the builder's manual the shoulder harness lug assembly was riveted to the (F-01446A-L, F01406A-R, and F-01406C) bulkheads using the rivets called out in figure two except the top-most rivets in the "tang" area of the lug.

The tolerances under the "tang" area is pretty tight so I've got to figure out a way to put a rivet in here.


Riveting Shoulder Harness Lug Assembly

In order to finish up step six, on page 30-06 of the builder's manual, where the shoulder harness lug assembly is attached to the (F-01406A-L and F-01406A-R) bulkheads I asked Van's Aircraft if I could substitute a CherryMax rivet in the top-most hole under the "tang" of the assembly and they said it would be okay since a CherryMax rivet is superior in torsion strength to that of a solid rivet.

I measured the depth of the material that the rivet would be sitting in with our CherryMax grip gauge and found that a CR3213-4-2 rivet would be the proper substitution for the AN470AD4-5 called for in figure two on page 30-06 of the builder's manual.

Riveting Shoulder Harness Lug Assembly

We used a CR3213-4-2 rivet to finish up securing the shoulder harness lug assemblies to the (F-01406A-L and F-01406A-R) bulkheads.

This is the left fuselage side.

Riveting Shoulder Harness Lug Assembly

This is the right fuselage side.

Riveting Shoulder Harness Lug Assembly

Now we have to rivet the aft portion of the shoulder harness lug assembly to the (F-01474-L and F-01474-R) aft fuselage top side skins. We are using AN426AD4-4 rivets here.

Riveting Bulkheads To Aft Fuselage

Step seven, on page 30-06 of the builder's manual also says to rivet the (F-01406C) bulkhead to the (F-01474-L and F-01474-R) aft fuselage top side skins, the (F-01475) aft fuselage top skin, the (F-01475A) skin doubler, and the (F-14131) upper aft fuselage rib so we'll go ahead and start that at this time as well.

*We've got to make sure we don't rivet the holes that we marked off earlier as indicated in figure three on page 30-06 of the manual.

Riveting Bulkhead To Aft Fuselage

One set six more to go on this side!

Riveting Bulkhead To Aft Fuselage

Nice!

Riveting Bulkhead To Aft Fuselage

As we are riveting the (F-01406C) bulkhead to the aft skins we started at the corners and worked our way upward and downwards in order to prevent "pillowing" of the skins, we also alternated evenly from the left to right sides of the fuselage as well.

We substituted AN426AD3-3.5 rivets for the AN426AD3-3 rivets that were called for...the -3 rivets seemed just a little too short.

Riveting Bulkheads To Aft Fuselage

We continued to work our way downwards and riveted the (F-01406A-L and F-01406A-R) bulkeads to the (F-01474-L and F-01474-R) aft fuselage side skins.


Joining Fuselage Halves

Here's a look from the inside...

In step four, on page 30-07 of the builder's manual, the (F-01473-L and F-01473-R) aft fuselage side skins need to be riveted to the (F-01418B-L and F-01418B-R) longerons and the (F-01474-L and F-01474-R) aft fuselage top side skins.

The area that I am refering to is in the center of this photograph just behind the bulkhead.

*We found that AN426AD3-4.5 rivets seemed a better length than the AN426AD3-4 rivets called for in figure three, page 30-07.

Joining Fuselage Halves

This is a closer view of the longerons and top and side skins we are riveting together.

We started at the aft-most section and worked our way forward but as you get closer and closer to the bulkheads it gets harder to see the tails of the rivets and harder and harder to get your arm around the bulkhead in order to hold the bucking bar squarely on the rivet tails.....something's got to be done, my arm is too short!

Joining Fuselage Halves

This is the left fuselage side.

Joining Fuselage Halves

This is a left fuselage view from the outside.


Joining Fuselage Halves

This is a right fuselage view from the outside.

Joining Fuselage Halves

We continue to work our way forward as much as we can reach and rivet the remaining fuselage (F-01418B-L and F-01418B-R) longeron substructures and the left side (F-14117) ELT mount to the (F-01474-L and F01474-R) aft fuselage top side skins.

There were four places where we had to use AN426AD4-4 "oops" rivets....the angles and spaces are kind of tight.

We are going to save the six rivets in the triangle area just aft of the vertical seam until we add additional support under the fuselage to allow us access to reach the tight spots by getting inside the baggage area.

Joining Fuselage Halves

This is the same area on the right fuselage side.

*We have to remember not to rivet anything in the area marked by the black tape yet.


Fuselage Support

I made two supports to be placed under the fuselage, one goes under the baggage bin and the other goes just aft of the vertical bulkhead seam.

We used this blue workout mat to help cushion the weight and avoid any unnecessary scratches.

Fuselage Support

This is the second support, it has a mat too but I didn't cut it yet.

Fuselage Support

This is what the supports look like when installed.


Joining Fuselage Halves

We riveted the three rivets on the left and right fuselage sides that are common to the (F-14145-L and F-14145-R) step attach angles to the (F-01484) center bottom skin using AN426AD3-3.5 rivets.

Next, we are attaching the (F-01426_L, F-01426-R, F-01427-L, and F-01427-R) baggage bin ribs bottom-most holes to the (F-01406B) bulkhead with LP4-3 rivets as per figure one, on page 30-04 of the builder's manual.

This photograph shows a plywood floor that I made so that we can get inside the baggage bin to gain access to hard to reach rivets.

Joining Fuselage Halves

We completed attaching the (F-01473-L and F-01473-R) aft fuselage side skins and the (F-01418B-L and F-01418B-R) longerons, and the (F-14117) ELT antenna mount, and the (F-01474-L and F-01474-R) aft fuselage top side skins to one another.

Joining Fuselage Halves

This is the left fuselage side....there is still more substructures to rivet yet.


Joining Fuselage Halves

We need remove two misplaced LP4-3 rivets that were set at the bottom edges of bulkheads (F-01406A-L, F-01406A-R, and F-01406B).

I have to use a special "pop" rivet removal tool to get these types of rivets out.

Joining Fuselage Halves

The bottom "blind" rivet needs to be removed here too.

*Both of these rivets will be replaced with AN470AD4-4 rivets.

Joining Fuselage Halves

My wife handles the rivet gun!

Joining Fuselage Halves

We attached the (F-01406C) bulkhead to the upper aft fuselage rib (F-14131).

*Don't forget to leave the second hole from the top open for now!

Joining Fuselage Halves

As per step two, on page 30-08 of the builder's manual, we are attaching the (F-01406A-L and F-01406A-R) bulkheads to the (F-01406B) bulkhead with rivets as called out in figure one, on page 30-04 of the builder's manual.

*Make sure not to rivet the third hole down, that will be done later when installing the baggage bin floors.

Joining Fuselage Halves

The right fuselage side.

Joining Fuselage Halves

We removed the plywood temporary floor in order to rivet the floor ribs to the bottom skin.

We riveted the baggage bin ribs (F-01425-L, F-01425-R, F-01426-L, F-01426-R, F-01427-L, and F-01427-R) to the (F-01484) center bottom skin.

Joining Fuselage Halves

Here is what it looks like from underneath.


Riveting Baggage Bin Ribs To Bulkhead

When we were attaching the (F-01425-L, F-01425-R, F-01426-L, F-01426-R, F-01427-L, and F-01427-R) baggage bin floor rib ends to the (F-01406B) bulkhead we found that some of the areas were pretty hard to get a rivet gun in so we checked with Van's Aircraft to see if we could use LP4-3 rivets when necessary. They said yes, so we substituted 12 AN470AD4-4 rivets with LP4-3 rivets.

Riveting Baggage Bin Ribs to Bulkhead

Here is what it looks like.

We still had to use an offset wedge to get a proper angle on the LP4-3 rivets set with our CherryMax G-27 hand rivet gun.

Joining Fuselage Halves

As per step four, on page 30-08 of the builder's manual, the (F-01470-L and F-01470-R) fuselage side skins were riveted to the fuselage "side horizontal" substructures using AN426AD3-4.5 rivets.

*We substituted AN426AD3-4.5 rivets for the AN426AD3-4 rivets called for because as before the -4 rivets seemed too short.

The next step is to start on the vertical lap joints...

Joining Fuselage Halves

In step five, on page 30-08 of the builder's manual, the (F-01470-L and F-01470-R) fuselage side skins and the (F-01473-L and F-01473-R) aft fuselage side skins were attached to the (F-01406A-L and F-01406A-R) bulkheads along the vertical lap joint with AN426AD3-4.5 rivets.

Here is what it looks like along the bottom....corners are the last to be riveted.


Dimple Baggage Bin Floors

As per step three, on page 32-04 of the builder's manual, the #30 and #40 holes along the inboard and forward edges of the (F-01447-L and F-01477-R) baggage bin floors were dimpled.

*I placed masking tape over, or near, the holes that don't get dimpled in order not to accidentally dimple them. This includes the nutplate center holes and where the (F-14141) baggage bin floor splice will go, and some of the holes around the inspection cover plates.

Figure one, on page 32-04 shows what holes do not get dimpled.

Make sure to dimple the correct side...flush top surface!


This is the bottom side of the right (F-01447-R) baggage bin floor.

Dimple Baggage Bin Floors

This is the bottom side of the left (F-01447-L) baggage bin floor.

Let the dimpling begin...

I used a combination of hand squeezers and our DRDT2 dimpling machine. In both cases the male dimple die is placed in the bottom of the tools and the female dimple die is in the top.

*The top surface of the baggage bin floor is the side against the table. The bottom surface is facing up.

I am using the hand squeezers to dimple the #40 holes.

This is the left (F-01447-L) baggage bin floor.

Baggage Bin Floor Splice

The baggage bin (F-14141) floor splice is the next piece to work on so after the protective blue vinyl was removed I edge deburred the part.


Attaching Nutplates To Baggage Bin Floor

As per step four, on page 32-04 of the builder's manual, I am riveting the K1000-08D nutplates to the forward edges of the (F-01447-L and F-001447-R) baggage bin floors.

*There are eight nutplates per side in this area.

Attaching Nutplates To Baggage Bin Floor

Step five, on page 32-04 of the builder's manual, also instructs that the two K1000-08D nutplates be installed to the forward edges of the access holes in the (F-01447-L and F-01447-R) baggage bin floor as well.

Final Drilling Center Hole In Baggage Bin Floor Nutplates

Step four, on page 32-05 builder's manual, instructs that the nutplate center holes of the forward inboard edges of the (F-01447-L and F-01447-R) baggage bin floors be final #19 drilled.

Final Drilling Center Hole In Baggage Bin Floor Nutplates

I am final #19 drilling the nutplate center holes of the (F-01447-L and F-01447-R) baggage bin floors foward inboard edges.

Van's Aircraft pre-punching holes is very good and all these holes were virtually all #19 sized! Just a couple needed minor touch ups.

Baggage Bin Tiedown Ring Installation

#19 final sizing complete.

*I will have to repeat this step at the hangar on the floor ribs....they turned out to be just as accurately pre-punched as these were!

Baggage Bin Tiedown Ring Installation

We have chosen to install four Van's Aircraft optional (CA BAGGAGE TIE DOWN) tie down rings in the baggage bin.

There are virtually no instructions on how or where to install these so you're pretty much on your own.

I started out by looking at the baggage bin area to see where all of the ribs were because the screws that secure these mounts to the floor are quite large and will require K1000-04 nutplates to accept a 14-28 countersunk screw and you certainly can't put that size screw into a rib flange! Doublers are going to have to be made, but what size?

I know the size of the tie down ring mount which is 1 3/4" in diameter so basically I had to work backwards in order to determine what size the doubler had to be. I used the "Standard Aircraft Handbook For Mechanics And Technicians" to help me figure out what size rivets, distances, and edge clearances needed to be met.

On page 136 of the handbook it states that the material thickness of the doubler must be as thick or thicker than the original structure so that means .0250" which is what thickness the floor is. Next what thickness of rivets should I use? The handbook (on page 140, figure 5-43) also states that for materials of .0320" or less that 1/8" rivets should be used. What will be the rivet edge distances? For 1/8" flush rivets (because the tie down ring mount must sit flat against the floor) the rule is 2 1/2 times the diameter so in this case 5/16". How far apart should the rivets be? The rivets should be at least 1" apart and if there are more than one row the rivets should be staggered from the first row and be at least 1/2" apart.

Baggage Bin Tiedown Ring Installation

Ultimately this is the doubler shape and size that I made. It is 2 3/4" in diameter and has two rows of 1/8" AN426AD4-4 rivets, not counting the AN426AD3-4 rivets that will be used to attach the two K1000-04 nutplates that will be used to screw the tie down mount to.

This is the approximate location of the front two tie down rings.

Baggage Bin Tiedown Ring Installation

This is the approimate location of the aft two tie down rings.

Baggage Bin Floor Splice

Back to easier things...I final reamed all of the #30 and #40 holes in the (F-14141) baggage bin floor splice and deburred the holes.

As per step one, on page 32-06 of the builder's manual, and referring to figure one, the four #40 holes were machine countersunk to accept a head of a AN426AD3 type rivet.

The two additional #30 holes were machine countersunk to accept the head of a AN426AD4-5 rivet.

Baggage Bin Floor Splice

I scuffed the (F-14141) baggage bin floor splice in preparation for priming.


Flap Motor Channel

The (F-14141) baggage bin floor splice was washed with acetone and primed with DupliColor DAP 1690 self etching green primer.

The (F-01405G) flap motor channel is next and after taking off the protective blue vinyl I edge deburred it.

Flap Motor Channel

I final reamed all of the #30, #40, and #19 holes on the (F-1405G) flap motor channel and deburred them and then scuffed all surfaces with a ScotchBrite pad in preparation for priming.

The #40 holes, where the nutplates will be attached, were dimpled as per step 4, figure three, on page 32-06 of the builder's manual.

Flap Motor Bracket

The (F-01466-L and F-01466-R) flap motor brackets need to be worked on next.

These are the two small brackets that will be attached to the mid fuselage brace and the (F-1405G) flap motor channel.

Flap Motor Bracket

The first thing that needs to be done is trim the excess (small tab) from the left (F-01466-L) flap motor bracket.

I cut the tab off with a bandsaw.

Flap Motor Bracket

There is a small tab on the right (F-01466-R) flap motor bracket that needs to be trimmed off too.

Flap Motor Bracket

As you can see the edge is rough and so it needs to be filed even with the rest of the (F-01466-L) flap motor bracket edge and then all the edges deburred.

You can also see the machining mark left from the bend angling done at the factory that will have to be removed.

Flap Motor Bracket

That machining line is on this side of the bracket too.

Nutplates On Baggage Bin Floor Splice

As per step two, on page 32-06 of the builder's manual, K1000-08 nutplates were riveted onto the (F-14141) baggage bin floor splice.

*Figure three, on page 32-06 shows the rivet call outs.

Baggage Bin Side Covers

There are four baggage bin side covers that will be installed in the baggage bin. They are: (F-01481-L, F-01481-R, F-01482-L, and F-01482-R).

They are here to protect the fuselage sides from denting in the advent of cargo shifting.

*Before I remove the protective blue vinyl I want to final ream and deburr all of the #30 holes and then use the edge break tool to put edge breaks on the forward and aft edges of (F-01481-L and F-01481-R) forward baggage bin side covers and on aft flanges of the (F-01482-L and F-01482-R) aft baggage side covers. If you use the edge break tool while the vinyl is still on it is less likely to develop any scratches.

Break Edges On Baggage Bin Side Covers

You can see the edge break in this photograph.

Baggage Bin Side Covers

Now for the edge deburring process!


Baggage Bin Side Covers

I scuffed the surfaces of the (F-01481-L, F-01481-R, F-01482-L, and F-01482-R). baggage bin side covers in preparation for priming.


Prime Baggage Bin Side Covers

After washing the (F-01481-L, F-01481-R, F-01482-L, and F-01482-R). baggage bin side covers with acetone they were primed with DupliColor DAP 1690 self etching green primer.

Primed Baggage Bin Side Covers

I only primed the back sides of the baggage bin side covers, the other sides will be primed after installation.

Tie Down Ring Doubler Fabrication

I am fabricating the four doublers that I will be using for the tie down rings that will be installed to the baggage bin floors.

I made a jig so that after rough cutting the doublers with the bandsaw I could final size them to a perfect circle at the stationary vertical sander.


Tie Down Doubler

I started out by drilling #40 guide holes in a template doubler and then match drilled the holes into each of these four doublers (labeling each according to where it will be located on the floor). The center hole is a #40 hole, it can be used as a guide hole for each of the individual doublers to locate the correct position needed in the (F-01447-L and F-01447-R) baggage bin floors.

*The chrome part that you see to the right is the actual tie down mount that will be screwed into the floor, it's the part that you will see.

These doublers will be physically located under the baggage bin floor.

This photograph shows all the doublers after the holes have been match drilled into the baggage bin floors (and also therefore the doublers) and are final sized.

Tie Down Doubler

This is a locator hole that I drilled into the baggage bin floor, there are a total of four of these (two per side).

Tie Down Doubler

This is the locator hole in the aft portion of the baggage bin floor near the access hole.

Tie Down Doubler Located

As you can see in this photograph, the doubler is clecoed into position but all the holes are still #40 holes, they will be match drilled and final sized in the following steps.

Everything is deburred after drilling.

Tie Down Doubler Drilling Holes In Floors

As you can see here all of the holes have been final sized and are still clecoed to the floor.

Tie Down Doubler Drilling Holes In Floors

The holes are final sized and deburred.

The holes around the edges have been final sized, nutplate holes still to go...

Tie Down Doubler Drilling Holes In Floor

This is what it looks like before drilling the larger holes for the center screw.

Tie Down Doubler Drilling Holes In Floor

To make sure that the center screw hole is acurately placed, the K1000-04 nutplate is clecoed into position.

I use a smaller than final size drill bit to start the center hole (don't want to mess up the nutplate threads) and then later enlarge the hole to final size to fit a 14-28 screw.

Joining Fuselage Halves

As per step six, on page 30-08 of the builder's manual, we joined the (F-01484) center bottom fuselage skin and the (F-01478) aft fuselage bottom skin together along the horizontal lap joint.

*We substituted AN426AD3-4.5 rivets for the places calling for the shorter AN426AD3-4 rivets and AN426AD3-5 rivets for the places calling for the shorter AN426AD3-4.5 rivets.

Joining Fuselage Halves

Now we are getting into some of the fuselage joining tightest spots. We are riveting the (F-01423B-L and F-01423B-R) baggage bin floor ribs to the (F-01406A-L and F-01406A-R) bulkheads, the (F-01470-L and F-01470-R) fuselage side skins, and the (F-01484) center bottom fuselage skin.

Some of the rivet callouts are found in figure one, on page 30-04, and the rest in figure two, page 30-08 of the builder's manual.

The rivet callouts for attaching the rib ends to the bulkheads are found on page 30-04. They are attached with a combination of AN470AD4-4 rivets and LP4-3 rivets...we used mostly LP4-3 rivets.

Fastening the (F-01423B-L and F-01423B-R) baggage bin ribs lower flanges to the (F-01470-L and F-01470-R) fuselage side skins and the (F-01484) center bottom skin callouts are found in figure two, page 30-08. They are attached with a combination of AN426AD3-4 rivets, AN426AD3-4.5 rivets, and MK-319-BS rivets for the really tight spots.

We found that there were three additional spots where we had to use MK-319-BS rivets.

Joined Fuselage Halves

Fuselage halves joined!

Joined Fuselage Halves

Nice!


Joined Fuselage Halves

It feels really good to finally have to two halves joined together.

Joined Fuselage Halves

It definitely takes two people to do this task.


Countersink Mid Fuselage Brace

There are eight holes on the forward side of the (F-01405F) fuselage center brace that need to be countersunk. Most were already done on the quickbuild fuselage but there were two that still needed to be machine countersunk to accept the head of a AN426AD3-4 rivet.

Figure two, on page 29-19 of the builder's manual shows which holes need to be countersunk. (They are the holes in the bottom row between the larger holes in this photograph.)

Countersink Mid Fuselage Brace

The two holes have been machine countersunk to accept the head of a AN426AD3-4 rivet.

Dimpled Holes In Baggage Bin Floor Ribs

As you may or may not recall, in step one, on page 32-05 of the builder's manual the (F-01447-L and F-01447-R) baggage bin floor skins needed to have two holes dimpled in order to receive two CS4-4 rivets near the area where the seatback hinges are. That was done but now I have to dimple these holes in the (F-01417-L and F-01417-R) seat ribs to accept the CS4-4 rivet as well.

*The red arrows in this photograph show the #30 holes that were dimpled, the right side of the fuselage floor ribs were dimpled as well.

Outboard Bushing Install

As per step three, on page 32-02 of the builder's manual the two (F-1030) outboard bushings were bolted to the (F-01433-L and F-01433-R) flap block brackets using hardware called out in figure three.

This is the left fuselage (F-01433-L) flap block bracket.

*Take note of the warning not to tighten the bolts to tight, there should only be enough friction on the bolts to be able to turn them slightly in the blocks.

DO NOT use standard torque values here!

The (F-1030) inboard bushing was bolted to the outboard side of the (F-01417-L) baggage bin floor rib using the hardware callout shown in figure one on page 32-03 of the builder's manual.

*Make sure that the previously drawn arrow is pointing up when installing the bushing.

*Make sure that the previously drawn arrow is pointing up when installing the bushing.

Clecoing Baggage Bin Floor Skins To Ribs

As per step five, on page 32-05 of the builder's manual, the (F-01447-L and F-01447-R) baggage bin floors were clecoed to the fuselage substructures, the (F-01406A-L and F-01406A-R) bulkheads, the (F-01406B) bulkhead, and the (F-01428-L and F-01428-R) side frames.

Clecoing Baggage Bin Floors To Ribs

While I was at it, I clecoed K1000-08D nutplates along the floor edge as well.

*Make sure you have plenty of clecos on hand!


Attaching Baggage Bin Floors To FuselageLots of Clecos!
Attaching Baggage Bin Floors To FuselageOkay, Let's start riveting!
Attaching Baggage Bin Floors To Fuselage

As per step six, on page 32-05 of the builder's manual, I started the process of riveting the (F-01447-L and F-01447-R) baggage bin floors to the fuselage substructures.

*The rivet callouts are found in figure one on page 32-05.

I used our G-27 CherryMax hand rivet gun to set the LP4-3 rivets.


Attaching Baggage Bin Floors To Fuselage

I put masking tape over the #30 holes that don't get riveted yet. These holes are where the (F-01481-L, F-01481-R, F-01482-L, F-01482-R, and F-14141) side panels and the baggage bin floor splice will be attached to the fuselage.

Attaching Baggage Bin Floors To Fuselage

Things are moving along, there are alot of rivets!

Attaching Baggage Bin Floors To Fuselage

It's pretty cool to see the floor going in.

Attaching Baggage Bin Floors To Fuselage

This is a tight spot. There are two LP4-3 rivets used to attach the (F-01447-L and F-01447-R) baggage bin floors to the (F-01428-L and F-01428-R) side frames on each side of the fuselage but space is limited.

*An offset wedge really is helpful here so that the rivet gun head can squarely set the LP4-3 rivet while still being at an angle to clear the fuselage side skin.

You can see the wedge just below the rivet gun head in this photograph.

Attaching Baggage Bin Floors To Fuselage

The left side rivets are set.

The right side rivets are set.

Clecoing Seatback Hinges To Baggage Bin Floors

Now it is time to cleco the six (F-01447B) seatback hinges to the (F-01447-L and F-01447-R) baggage bin floors.

*Make sure that you have the CS4-4 rivets in the floor set before clecoing the seatback hinges in because the second row of hinges sits pretty close to where these holes are and it would be tough to set them after everything is clecoed in place.

Attaching Seatback Hinges To Baggage Bin Floors

The seatback hinges will be attached using LP4-3 rivets.

Attaching Seatback Hinges To Baggage Bin Floors

The seatback hinges have been riveted to the baggage bin floors.

Priming Baggage Bin Floors

Before I rivet the (F-01481-L, F-01481-R, F-01482-L, and F-01482-R) baggage bin side covers in place I want to prime the parts of the pre-scuffed floors so that they will be protected from corrosion. I masked the areas off, cleaned them with acetone and primed them with DupliColor DAP 1690 self etching green primer.

Priming Baggage Bin Floors

The quickbuild kit came primed but this is just extra protection for the areas on the floors that I scuffed before installing them.

Primed Baggage Bin Floors

I removed the masking paper after I got done priming the floors.


Finishing Floor Installation

I riveted the K1000-08D nutplates along the length of baggage bin floor to the substructures. The next step is to rivet the (F-01447-L and F-01447-R) baggage bin floors to the (F-01406A-L, F-01406-R, and F-01406B) bulkheads.

*The rivet callouts for this is found in figure two, on page 32-05 of the builder's manual.

Finishing Floor Installation

The nutplates have been installed and the floor has been installed to the bulkheads.

I used mostly the 3x rivet gun and a short tungsten bucking bar to set the rivets, a few places I was able to use the hand squeezer as well.

The instructions never mentioned it, but the (F-01491-L and F01491-R) side frame ribs need to be riveted to the (F-01406A-L and F-01406A-R) bulkheads, there isn't even a mention as to what rivets that should be used. I elected to attach them now and I used AN470AD3-3.5 rivets.

The red arrows are pointing to the side frames I am refering to and there are two rivets per side that need to be set.

The rivet callouts for this area are found in figure two, on page 32-05 of the builder's manual.


Access Cover Nutplate Install

The K1000-08D nutplates were installed in the access cover areas with AN426AD3-3.5 rivets and in the really tight areas AAC32 Cherry rivets were used.

Access Cover Nutplate Install

The same rivets were used here as well.

If you look close you can see the two AN470AD3-3.5 rivets that I used to attach the (F-01491-R) side frame to the (F-01406A-R) bulkhead.

Cleco Baggage Bin Floor Splice To Floors

As per step three, on page 32-06 of the builder's manual, the (F-14141) baggage bin floor splice was clecoed onto the (F-01447-L and F-01447-R) bin floors. I put masking tape on the eight holes that do not receive LP4-3 rivets so we didn't have any "boo boos".

Baggage Bin Floor Splice Riveted In Place

I riveted the (F-14141) baggage bin floor splice into place using the rivet callouts specified in figures one and two on page 32-06 of the builder's manual.

Clecoed Flap Motor Channel Into Place

The (F-01405G) flap motor channel was clecoed into place on the (F-01405F) mid fuselage brace.

*Make sure to take note that the flap motor channel forward side, at the bottom of the channel, is supposed to mate towards the aft side of the (F-01405L) doubler at the bottom.

Figure one, on page 32-07 of the builder's manual depicts the orientation.


Baggage Bin Side Covers Clecoed Into Place

The (F-01482-R) aft baggage bin side cover and then the (F-01481-R) forward baggage bin side cover were clecoed into place to the fuselage.

*Make sure that the side cover flanges lay under the (F-01491-R, and F-01422-R) fuselage ribs.

Baggage Bin Side Covers Clecoed Into Place

The (F-01482-L) aft baggage bin side cover and then the (F-01481-L) forward baggage bin side cover were clecoed into place to the fuselage.

*Make sure that the side cover flanges lay under the (F-01491-L, and F-01422-L) fuselage ribs.

Riveted Baggage Bin Side Covers To Fuselage

The (F-01482-R) aft baggage bin side cover and the (F-01481-R) forward baggage bin side cover were riveted into place using the rivet callouts specified in figure one on page 32-08 of the builder's manual.

Riveted Baggage Bin Side Covers To Fuselage

The (F-01482-L) aft baggage bin side cover and the (F-01481-L) forward baggage bin side cover were riveted into place using the rivet callouts specified in figure one on page 32-08 of the builder's manual.

Riveted Baggage Bin Side Covers To Fuselage

These baggage bin side covers are a very nice feature, I'm sure they add a great deal of strength too.


Riveting Flap Motor Channel In Place

As per step seven, on page 32-07 of the builder's manual, the upper flange of the (F-01405G) flap motor channel was rivet to the (F-01405F) mid fuselage brace using the rivet callouts specified in figure one (AN470AD4-4) rivets.

Riveting Flap Motor Channel In Place

Working on anything in the interior baggage bin and cockpit areas is a bit of a chore, then again I guess that's "par for the course" when working on airplanes!

Riveting Flap Motor Brackets In Place

As per step three, on page 32-07 of the builder's manual, the two (F-01466-L and F-01466-R) flap motor brackets were clecoed and then riveted to the (F-01405G) flap motor channel using the rivets specified in figure two of the manual.

The space is pretty tight here so go easy!

Riveting Flap Motor Channel In Place

In step 4, on page 32-07, the lower end of the (F-01405G) flap motor channel is riveted to the (F-01405L) bulkhead doubler with AN470AD4-4 rivets.

This is what it looks like on the other side.


Scuffing Air Vent Attach Points

I traced around the cockpit NACA air flow vent assembly so that the area where they will eventually be attached to wouldn't be painted over.
They are supposed to be bonded into place according to steps five through seven on page 29-22 of the builder's manual.
This is the right fuselage side.

This is the left fuselage side.


Preparations For Painting

It's time to start masking off areas and preparing the cockpit and baggage bin areas for painting.

Our forward cockit is a quickbuild and the upper deck of the forward cockpit has been installed. I didn't want to paint the stainless steel firewall so I decided to mask it off. I also didn't want to paint in the bays where the fuel lines and electrical lines would go so I am masking them off as well.


Preparations For Painting

The empennage and flight control bays were masked off too.

Preparations For Painting

Priming the interior is near, just about everything is masked off.


Assembling The Air Vents

As per step five, on page 29-22 of the builder's manual, the NACA air vent assemblies were put together using figure three as a reference.

Assembling The Air Vents

The (SV-10-L and SV-10-R) vents are bonded to the (SV-6) aluminum "whisper flow" eyebal vents with a thin bead of clear RTV silicone adhesive. The (F-14186-L and F-14186-R) NACA vent brackets are then bolted to the rest of the assembly.

Adhesive Used For Air Vent Assembly.

This is the RTV silicone adhesive that I used.


Primed Bare Metal Areas In Baggage BinThe outside of the fuselage was masked off in preparation for priming.

This is a temporary setup, when the outside of the airplane is painted, it will be done in a paint booth.
Primed Bare Metal Areas In Baggage BinThe bare metal areas in the baggage area that were previously scuffed were washed with acetone.
Primed Bare Metal Areas In Baggage BinThe bare metal areas in the baggage area were primed with DupliColor DAP 1690 self etching green primer.

Preparations for Priming

The primed surfaces were lightly sanded in preparation for the entire inner fuselage area to be primed with Stewart Systems smoke gray primer. As you can see some of the rivet heads needed additional primer.


Painted The Air Vent Assemblies

The air vent assemblies were primed with Stewart Systems E7510 white primer and then after drying fully painted with EkoCrylic E5301 smoke gray topcoat paint.


Priming Inner Fuselage

The inner fuselage was primed with Stewart Systems E7520 smoke gray primer.

Prime NACA Vents

The inner spaces on the (F-01470-L and F-01470-R) fuselage skins where the (SV-10-L and SV-10-R) NACA vent assemblies will be attached needs to be primed in order to prevent corrosion.
I laid up two paper templates of the "lip" areas of the vent assemblies and then traced the inner line onto the skin so I knew where to apply the primer, and where not to apply the primer, since these assemblies are supposed to be glued into place with silicone adhesive.

This is the left fuselage side.

Clecoed Fuel Line Brackets

There are eight (F-01498A) fuel line brackets that need to be clecoed into position to be attached to the (F-01438-L and F-01438-R) cover ribs.

*Figure two on page 31-02 of the builder's manual shows how the brackets should be oriented, make sure that the larger slot of each bracket is on the bottom!

This is the left side of the fuselage.

Clecoed Fuel Line Brackets

This is the right side of the fuselage.

Washers Used For Riveting Fuel LIne Brackets

*Step 3, on page 31-02 of the builder's manual, also tells you which side of the bracket the LP4-3 rivet heads should be placed.
In some spots they suggest using these NAS1149FN432P washers to protect the plastic (F-01438-L and F-01438-R) fuel line brackets.

Bolt Obstructing Riveting Of Fuel LIne Bracket

I used our G-27 CherryMax hand rivet gun to set the LP4-3 rivets.

*You will definitely need a wedge tool to properly set some of these rivets because the space is limited.
There are four rivet holes that are blocked by the bolt heads in the spar channel that will require special attention in order to properly set the rivet without removing the bolt.....the normal wedge just doesn't work, I'll show you what I did later but first I have to go make the special wedge to do the job....


Andair Fuel Selector

An Andair FUEL-FS20X2-T fuel pump is used in the RV14A kit.
This is the box it came in....

Andair Fuel Selector Valve Body

This is the FUEL-FS20X2-T fuel pump and as per step two, page 31-03 of the builder's manual, the lever is supposed to be removed in order to proceed to the next steps.

*Don't forget to read the instructions and take note of the requirement to use Loctite 648 when resetting the screws.

DON'T FINAL SET THE SCREWS UNTIL YOU ATTACH THE NUTPLATES THOUGH!

Disassemble Fuel Selector Valve Lever

Got the lever off, that's fairly easy, they supply an allen wrench to do the job.

Reposition Fuel Selector Valve Elbows

Step three, figure one, on page 31-03 of the builder's manual, has you reposition each of the three elbow fittings.
At this point you might be tempted to reset the screws using the Loctite 648 retaining compound but don't do it until step four is completed!

Install Fuel Valve Nutplates

There are three K1000-3 nutplates that need to be attached to the fuel selector valve body.

I used our hand squeezer to attach the nutplates with AN426AD3-4 rivets and had to temporarily remove an elbow so that the squeezer head would not contact it.....this is why you don't want to final set the screws until the nutplates are attached!

Installed Fuel Valve Nutplates

The K1000-3 nutplates have been installed, the individual elbows positioned correctly, and the screws set with Loctite 648 as per the manufacturer's recommendation.

Loctite 648

Loctite 648

Screws For Fuel Valve Plate Cover

The Andair fuel selector valve faceplate needs to be machine countersunk to accept these three MS24693-C273 screws.

Machine Countersinking Fuel Valve Plate Cover

I used a #12, 100° countersink bit in our deburring tool to hand countersink each screw hole.


3003 Aluminum Fuel Line

Aluminum tubing (AT0-035x3/8) is supplied with the kit to make fuel lines out of and it comes in an eight foot coil like this.

*Unless you have made fuel lines from aluminum before it might be a good idea to buy extra aluminum tubing to practice on to get the technique right....it's pretty cheap and is well worth the trouble!

It is also known as soft aluminum 3003 and is 3/8" outside diameter and .035" thick.

3003 Aluminum Tubing

Soft Aluminum tubing3003.

Unwind Fuel Line Stock

Back to making fuel lines....you have to carefully unwind the coil and straighten it out as best that you can.

Main Fuel Lines Cut

As per step two, on page 31-06 of the builder's manual, two 27" sections need to be cut which will eventually become the (F-14109A-L and F-14109A-R) fuselage side-valve fuel lines.

I used an Imperial (TC 1000) tubing cutter to make the cuts in the tubing.

Andair Fuel Pump

The RV14A standard fuel pump is an Andair (EX-PX375-TC) pump.

This is the box that it came in.

Andair Fuel Pump

This is the Andair (EX-PX375-TC) fuel pump.

Fuel Pump Wiring

Step one, on page 31-04 calls for the Andair (EX-PX375-TC) black wire to be trimmed to 4".

A (ES-31890) ring terminal is to be attached to the black wire and a (ES-421-0108) female spade connector is to be attached to the red wire.

Fuel Pump Wiring

I double crimped each connector to the respective wires as per step two, figure two, on page 31-04 of the builder's manual.

*In case you're curious, these are 22 gauge wires.

Brake Hydraulic Reservoir

I started to work on the (VA-107) brake fluid hydraulic reservoir. I want to clean it and get it ready for painting....


Removed Firewall Masking Tape

I'm back at the hangar and wanted to get the last few little pieces of masking tape removed from the firewall from when I painted it, so before I did anything I crawled into the space under the instrument panel and picked them out....better!

After that, I checked the fit of the (VA-107) brake hydraulic reservoir to see if the holes in the attachment tabs lined up with the pre-drilled holes in the forward side of the (F-1401B-R) firewall as per step two on page 33-06 of the builder's manual....everything lined up great!

Bolt Interfering With Fuel Bracket Riveting

Remember those holes that were being blocked by a bolt in the spar channel that made it difficult to rivet the (F-01498A) fuel line bracket to the (F-01438-L and F-01438-R) cover ribs?

I made a wedge tool that made it easy to set the LP4-3 rivets.

Ferrule To Become Rivet Wedge Tool

First go get a 3/32" ferrule and stop set at your favorite hardware store, you're going to want to use the cylindrical ferrule for this wedge tool.

Rivet Cylinder Wedge Tool

Next grind an angle on one end of the ferrule. (About the same angle that you find on the trailing edge wedge for the rudder (R-916-1 or VA-140) it's only a few degrees.

Riveting Fuel Line Brackets In Place

Now you're ready to go! The rivet stem slides right into the ferrule, the cylinder of the ferrule is thin enough to get past the bolt head, and the rivet gun head sits squarely on the rivet head and sets the rivet easy peasy!

Riveting Fuel Line Brackets In Place

All of the (F-01498A) fuel line brackets are attached to the (F-01438-L and F-01438-R) covers ribs.

Brake Hydraulic Reservoir

I scuffed the (VA-107) brake fluid reservoir with a red ScotchBrite pad and washed it with acetone and then primed it with Tempo A702 green primer.

This part is going to receive several coats of paint and I will show the final version later on in the blog page.

Flaring Tool

I want to start practicing on fuel line fabrication so I ordered some extra 3003 soft 3/8" diameter aluminum tubing to practice flaring and bending on.

This is a heavy duty Parker Hannifin 37° flaring tool (212FB) that I will be using.

Flaring Tool

As you can see there are several different sized tubes that this tool can flare but I want to make sure that the 3/8" dies are selected.

Flaring Tool

On this side of the flaring tool there is a stop that you use when you insert the tubing. When the tubing touches this stop it indicates that you will have enough material to make an acceptable flare.

They recommend that a small bit of oil or grease be placed on the conical flarer so that you don't get any gauling or stretching of the aluminum during the process.

Fluted Aluminum Tubing

Not bad for the first time! This is a 37° flare and I found that when tightening the clamps and the flare cone that you don't have to use a lot of force to make good flares don't use gorilla force!

Fuel Line Centerline Marking Jig

Before I make any bends on the aluminum tubing I like to draw the centerline of the tubing so that when measuring or lining things up at least I can be somewhat accurate in what I am doing.

I made this simple little centering jig out of wood which has a 3/8" hole drilled into it and lines drawn 90° from each other. I slip the jig over the tube and use a sharpie to transfer the marks onto the tubing.

Fuel Line Centers Lay Out

Next, I lay the tube on an aluminum angle and using a ruler I make centerline marks along the length of the tube to the other end and connect the lines.....I know it's kinda labor intensive but....

Fuel Line Centers Marked

This is what it looks like after the lines have been drawn.

Fuel Lines Cut To Length

I cut three lengths that will be used in fuel lines later on. The 6" tube will become the (F-14109B) valve-filter fuel line.
The 11 1/8" tube will become the (F-14109C) pump-firewall fuel line.
The 27" tube will become one of the two (F-14109A-L or F-14109A-R) fuselage side valve fuel lines.

Bending Fuel Line

I flared one end of each of the four fuel line tubes.

Flared Fuel Line Ends

Here is what they look like after flaring.

*Be sure to inspect each flare to make sure there isn't any cracks, splits, gauling, or excessive stretch marks.

Tubing Bender

This is a General (NO. 153) compound tube bender that I will be using in the bending operations.

Tubing Bender

I found in my practice runs that the 3/8" tube openings were too tight and left unacceptable gouges in the aluminum tubing material so I took a round file and opened up the leading edges of the passage ways somewhat and polished the metal so that this would not happen in the future use of the tool.
The index marks, on the side scale, that are used to start and keep track of the bends weren't able to meet each other easily before I opened up the passage ways as well.

Tubing Bender

This is the other edge that I filed and polished.

Right Angle Fuel Line Bend

Now the bending tool makes nice smooth bends.


Ream Wing Root Fuel Line Hole

The holes in our quickbuild (F-01470-L and F-01470-R) fuselage side skins are not large enough to install the AN833-6D elbows so they need to be final reamed and deburred.

This is the left side of the fuselage and shows the holes after they were final reamed and deburred.

Ream Wing Root Fuel Line Hole

This is the right side of the fuselage and shows the holes after they were final reamed and deburred.

*The hole is 9/16" in diameter.

Install Fuel Line Elbow

As per step three, page 31-05 of the builder's manual, the AN833-6D elbows were installed and clocked vertically and the AN924-6D nuts secured finger tight at this time.

Install Fuel Line Elbow

This is what it looks like on the inside.

Install Fuel Line Elbow

The AN833-6D elbow and AN924-6D nut was installed on the right side as well.


Installed Fuel Selector Valve

As per step six, figure two, on page 31-03 of the builder's manual, the Andair (FUEL-FS20X2-T) fuel selector valve was attached to the (F-14102) fuel selector valve bracket with three MS24693-C273 screws.

*The lever will be attached after I install the fuel filter and fuel pump.

Andair Fuel Filter

This is the Andair (FUEL-FX375-MK) fuel filter.
It comes standard with the RV14A kit.

Fuel Filter Direction Arrow

*Take note of the arrow that shows the direction of fuel flow.

Loctite 567 Thread Sealant

As per step three, on page 31-04 of the builder's manual, thread sealant is to be applied to the threads of the fuel filter. I chose Loctite 567 for this and applied it to the fuel filter 1/4" NPT threads.

Installed Fuel Filter

The Andair (FUEL-FX375-MK) fuel filter was attached to the Andair (ES-PX375-TC) fuel pump.


Installed Fuel Pump And Filter

The Andair (ES-PX375-TC) fuel pump/ (FUEL-FX375-MK) fuel filter assembly was attached to the (F-14108A and F-14108B) fuel pump brackets making sure that the black wire (ES-31890) ring terminal fuel ground wire was between the fuel pump bracket and the AN515-8R8 screw head as per figure three, on page 31-04 of the builder's manual.

Installed Fuel Selector Lever

I reattached the Andair (FUEL-FS20X2-T) fuel selector lever to the fuel valve body.

Left Fuel LIne Template Wire

Time to fabricate fuel lines.

I first made an aluminum rod template of the fuel line according to the specifications given on pages 31-06 and 31-07. This helps when trying to figure out which way to orient the fuel line in the tubing bender when making the bends...don't want any mistakes, plus it's just it little bit easier to visualize what the part will look like. This is the left fuel line wire template.

Fuel Line Flare Nut And Sleeve

The fuel line will be made from a 27" piece of (AT0-035X3/8) aluminum tubing and use two (AN819-6D) sleeves and two (AN818-6D) coupling nuts (the blue hardware shown in this photograph).

Flared Fuel Line End

The one end of the tube has already been flared.

*Don't forget to inspect the flares.

First Bend Line Marked

The next step is to make the first bend mark which is 1 1/2" from the end of the flare.

Flare Nut And Sleeve

Install a (AN819-6D) sleeve and a (AN818-6D) coupling nut by sliding them into position from the unflared end to the flared end.

*Make sure to get the sleeve and nut put on in the proper direction!

First Bend In Fuel Line

The first bend is a 28.3° bend and you can either refer to figure two on page 31-06 and figure one on 31-07 to get the angle right, or you can do as I did, and used a digital protractor and draw reference angles on a flat piece of plywood to refer to.

*The curved pages of the manual makes it hard to get a good reference angles, that's why I draw them out on flat plywood.

One bend down, two more to go!

Right Angle Fuel Line Bend

The second bend is a 90° bend to the left. If you hold the fuel line over the right side view in figure two, on page 31-06 of the builder's manual, you can make the second bend mark line.

Here is where the wire template really came in handy, I drew the line on the wire, which was was held over the right side view, and then used this to double check the line that I drew onto the actual aluminum tube that I was bending....both came out the same so now the bend is good to go.

It was also handy to use the wire template to figure out how I should orient the tubing into the bender to make the bend in the right direction, it's not as easy as it seems!

Fuel Line Bends

Two bends down, one more to go.

*I think the last 90° bend is the hardest to make because it is a compound bend and yes, it is a downward 90° bend, but it also has to be bent slightly rearward as well....I didn't realize this because I made my first left fuel line at the home shop but should have made it at the hangar, in the presence of the fuselage, so I could adjust the wire template that I had to reflect this slight rearward angle in order to bend accordingly.

Third Fuel Line Bend Marked

The mark for the third bend line is 19 1/4" as measured from the centerline of the flared end of the aluminum tube.

The third bend is 90° downward but is also slightly aft so make sure you reference your fuselage in order to know how far aft that angle is....it isn't much but it's there!

Left Fuel Line

This is the second (f-14109A-L) fuselage left side fuel line that I made at the hangar and it fit well after I learned from my first attempt....glad I had extra aluminum tubing!

After the third bend was made the end of the tubing needs to be trimmed slightly. The tubing can be held over the front view illustration in figure two on page 31-06 of the builder's manual to get the final dimension.

After the final cut is made and the end has been deburred a flare has to be done. Make sure that the remaining AN819-6D sleeve and AN818-6D coupling nut are installed and in the proper direction before making the flare!

Left Fuel Line Installed

I inspected the flare and then cleaned out the line with compressed air and then temporarily installed the line with the coupling nuts only "drawn" finger tight.

Right Fuel Line Template Wire

The (F-14109A-R) fuselage right side valve fuel line is pretty much a mirror to the left one. I started out by making a wire template to help me out in the orientation and fabrication of the right fuel line.

First Bend In Right Fuel Line Marked

Just like before, the first bend is 28.3° but this time to the right.

*Make sure to slide at least the AN819-6D sleeve from the open end of the tube before you make the first bend and make sure that it is installed in the proper direction because once you make the bend you won't be able to install the sleeve.

Two more bends to go!

Right Fuel Line Installed

The (F-14109A-R) fuselage right side fuel line is fabricated, cleaned with compressed air, and temporarily installed with the coupling nuts only "drawn" finger tight.


Fuel Filter Line And Hardware

The (F-14109B) valve-filter fuel line is the next fuel line to fabricate. It is fabricated from a 6" piece of (AT0-035X3/8) soft aluminum tubing.

As per step three, figure one, on page 31-09 of the builder's manual, the end is flared and inspected first. A AN819-6D sleeve is installed by sliding it from the unflared end of the tube to the flared end. (Make sure the sleeve is oriented in the proper direction.)

A bend mark is made onto the tubing 2.924" (2- 59/64") from the end of the flared part of the tubing. (Use the illustration in figure one, page 31-09 to make the mark.) Bend the tubing 76° checking the angle against the illustration on page 31-09.

Fuel Filter Line

After I made the bend, I trimmed the (F-14109B) valve-filter fuel line to final length and deburred it. Two AN818-6D coupling nuts and a AN819-6D sleeve were slid into position and the end was flared.

The flare was inspected and then the line was cleaned with compressed air.

Fuel Filter Line Installed

The (F-14109B) valve-filter fuel line was temporarily installed between the (FUEL-FS20X2-T) fuel selector valve and the (FUEL-FX375-MK) fuel filter as per figure two, on page 31-09 of the builder's manual, and the coupling nuts were only tightened "finger tight".


Yaw Damper Servo Mount Parts

I am working on the autopilot yaw servo mounts today. There are three pieces that need to be edge deburred and prepared for priming. They are: (F-14189A) yaw servo plate, (F-14189B) yaw servo support, and (F-14189C) yaw servo spacer.

Yaw Damper Servo Mount Plate

The (F-14189A) yaw servo plate has been edge deburred, all the holes final reamed and deburred, and the surface scuffed in preparation for priming.

Yaw Damper Servo Mount Support

The (F-14189B) yaw servo support is next to be edge deburred.


Yaw Damper Servo Mount Support

The (F-14189B) yaw servo support has been edge deburred, all of the holes have been final reamed and deburred, and the surface scuffed in preparation for priming.

Cleco Yaw Damper Servo Mount Parts Together

I clecoed the (F-14189A) yaw servo plate and the (F-14189B) yaw servo support together because there are four #40 holes on the top of the yaw servo plate that need to be machine countersunk in order to receive the head of a AN426AD3-4.5 rivet as per indicated in figure two, step two, on page 58-02 of the builder's manual.

Machine Countersinking Yaw Damper Servo Mount Plate

Clecoing the parts together helps to guide the pilot in the countersink bit that I am using in the debur tool.

Machined Countersunk Yaw Damper Servo Mount Hole

Two done, two more to go.

Yaw Damper Servo Mount Spacer

The (F-14189C) yaw servo spacer is the next to be deburred.


Yaw Damper Servo Mount Spacer

The (F-14189C) yaw servo spacer has been edge deburred, the holes final reamed and deburred, and the surface scuffed in preparation for priming.

All of the parts were washed with acetone and primed with Tempo A702 green primer.

Yaw Damper Servo Mount Parts Primed

(F-14189A, F-14189B, and F-14189C) have been primed.

Brake Hydraulic Reservoir Painted

The (VA-107) brake hydraulic reservoir has been painted VHT high temperature engine enamel.


Yaw Servo Plate Clecoed To Yaw Servo Support

We have elected to install an autopilot yaw servo mount in the airplane because it is easier to do it now than it would be later as it is located under the elevator bellcrank and autopilot pitch servos back in the rear empennage (At the F-01407-L and F-01407-R side frames).

Section 58 deals with the installation process of the yaw servo mount system.

As per step three, on page 58-02 of the builder's manual, and refering to figure two, the (F-14189A) yaw servo plate was clecoed to the (F-14189B) yaw servo support.

Yaw Servo Assembly Riveted

The (F-14189A) yaw servo plate was riveted to the (F-14189B) yaw servo support with AN426AD3-4.5 rivets, making sure that the flush manufactured head was located on the top side of the (F-14189A) yaw servo plate.

Yaw Servo Assembly Riveted

Here's another angle of the riveted yaw servo mount assembly.

Template

I am working on this project in two locations and on my next trip to the airport I intend to install a fuel fitting to the forward firewall. It is to be clocked at 40° from vertical so in order to get the angle right I made a template so that the AN833-6D elbow can be easily set on the front left side of the (F-01401B-L) forward firewall.


AN833-6D Elbow Fitting

Now I am at the airport...

This is what the AN833-6D elbow fitting looks like.

Fuel tank sealant is supposed to be applied to the flange of this AN833-6D elbow fitting and then it is to be installed onto the left side of the (F-01401B-L) forward fuselage firewall and clocked at an angle of 40° from vertical.

*The plans are kind of confusing on page 31-05 and later on page 31-11. On page 31-05 they say to set the fitting at 25° (for nosegear aircraft) but on page 31-11 they say to set the angle at 40°...so which is it?

I called Van's Aircraft and they said to use the 40° angle from vertical.

Clocking Marks For Fuel Fitting

Remember the template that I made? Here are the marks on the firewall that I used so that I could get the 40° angle right.

I am using a 5 minute tank sealant to set the elbow fitting and also the brake fluid reservoir in place so there isn't any time to waste getting these two items set.

Firewall Fuel Fitting Installed

As per Van's Aircraft builder support instructions, as to the correct angle, and per figure three, on page 31-11 of the builder's manual, and using hardware as per figure one, on page 31-05 of the builder's manual, I installed the AN833-6D elbow fitting.

Brake Reservoir Installed



As per step three, on page 33-06 of the builder's manual, tank sealant was applied to the outer diameter of the (VA-107) brake fluid reservoir nipple and the reservoir was attached to the right foward side of the (F-01401B-R firewall using the hardware specified in figure two.

Firewall Parts Installed Section 33

Nice!

F-14109C Fuel Line

As per the instructions on page 31-10 of the builder's manual, the (F-14109C) pump-firewall fuel line was fabricated.

F-14109C Fuel Line Installed

The (F-14109C) pump-firewall fuel line was temporarily installed between the Andair (ES-PX375-TC) fuel pump and the AN833-6D elbow fitting on the firewall.


Retouch Painting Needed

There is a small area on the (SV-10-R) air vent assembly that needs paint touch up. When I was the removing masking tape after painting, I accidently pulled a 1/4" x 1/4" chip of paint from the top coat.

Paint Touch Up On Air Vent Assembly

I touched up the paint chip on the right (SV-10-R) air vent assembly with Stewart Systems E-5465 EkoCrylic royal blue paint.

Paint Touch Up On Air Vent Assembly

Not too bad, I might block sand this with 1200 grit sandpaper later before I install it.


Roll Over Structure Parts

These are the parts that make up the roll over structure described in section 37 of the builder's manual.

*All of the metal in this structure is pretty thick so while it looks simple to get these pieces edge deburred and ready to go, it took me awhile to get it all done.

Roll Bar Brace Brackets

Using the bandsaw, I separated the (F-01432B-L and F-01432B-R) roll bar brace brackets.

Roll Bar Brace Brackets Separation

One piece becomes two.

Roll Bar Bushing Doublers

I separated the (C-01432) bushing doublers into four parts.

Roll Bar Bushing Doublers Separation

One piece becomes four.

Roll Bar Bushing Covers

I separated the (C-01433) bushing doublers into four parts.

Roll Bar Bushing Covers Separation

One piece becomes four.

Skin Stiffeners F-14125

I separated the (F-14125) skin stiffeners into two parts.

Skin Stiffeners F-14125 Separation

One piece becomes two.

These (F-14125) skin stiffeners will need some extra material removed later so this won't be their first trip to the bandsaw!

Roll Bar Parts Separated

All the parts are separated now.

Deburring F-01432B-R Roll Bar Brace Bracket

Time to start deburring all of the individual parts.

I started with the first of two (F-01432B) roll bar brace brackets. First I'll debur the edges.

Now that the roll bar brace brackets are separated they get a new number. This one is now called (F-01432B-R) and you have to pay attention because there is a left and right one so be sure to study figure two, on page 37-02 of the builder's manual!


Deburred F-01432B-R Roll Bar Brace Bracket

After I edge deburred the (F-01432B-R) right roll bar bracket I scuffed the surfaces with a red ScotchBrite pad.

Deburred F-01432B-L and F-01432B-R Roll Bar Brace Brackets

Both of the (F-01432B-R and F-01432B-L) roll bar brackets have been edge deburred and all holes have been final reamed and deburred.

Scuffed all surfaces with a red ScotchBrite pad.

Deburring F-1231E Roll Bar Brace Splice

There are two (F-1231E) roll bar splice plates that need to be deburred next, these plates are used to connect the two roll bar frame assemblies together at the top.

Deburred F-1231E Roll Bar Brace Splice

I edge deburred the first of the two (F-1231E) roll bar splice plates.

Scuffed F-1231E Roll Bar Brace Splice

I reamed and deburred all of the #30 holes and scuffed the surface with a red ScotchBrite pad.


Deburring Second F-1231E Roll Bar Brace Splice

Did I mention there were two of these?

This is the second of the two (F-1231E) roll bar splice plates.

*These plates are pretty thick, they average about .0595" thick each!

Deburred F-1231E Roll Bar Brace Splices

I edge deburred the second of the two (F-1231E) roll bar splice plates.

Reamed and deburred all the #30 holes and scuffed all surfaces with a red ScotchBrite pad.

Deburring F-01432A Roll Bar Brace

This is the (F-01432A) roll bar brace, it is the piece that supports the main roll bar frame back towards the aft bulkhead assembly.

Deburring F-01432A Roll Bar Brace

I edge deburred the (F-01432A) roll bar brace.

This is what the bottom side looks like.

Deburring F-01432A Roll Bar Brace

This is what the top side looks like.


Scuffed F-01432A Roll Bar Brace

I final reamed and deburred all of the holes in the (F-01432A) roll bar brace and then scuffed all surfaces with a red ScotchBrite pad.

As per step two, on page 37-02 of the builder's manual, there are six #30 holes on the forward tab of the (F-01432A) roll bar brace that need to be dimpled. These holes are indicated in figure two.

Dimpling F-01432A Roll Bar Brace

These are the six #30 holes that I am referring to. I dimpled them using our DRDT2 dimple machine.

Dimpled F-01432A Roll Bar Brace

Here is a better view of where the tab is located, it is shown on the right end of this photograph of the roll bar brace.

*Make sure that you dimple the holes so that the flush side is on the upper surface of the (F-01432A) roll bar brace.

Dimpling F-01432B-L and F-01432B-R Roll Bar Brace Brackets



As per step two, on page 37-02 of the builder's manual, I dimpled the #30 holes on the upper tabs of the (F-01432B-L and F-01432B-R) roll bar brace brackets as indicated in figure two.

I used the hand squeezer to dimple these.

Dimpling F-01432B-L and F-01432B-R Roll Bar Brace Brackets

This is a simple "mock up" of where these (F-01432B-L and F-01432B-R) roll bar brace brackets will be located at the end of the (F-01432A) roll bar brace.

Dimpling F-01432B-L and F-01432B-R Roll Bar Brace Brackets

*Don't forget, the dimples are supposed to be flush side up at the top of these roll bar brace brackets!

Dimpled F-01432B-L and F-01432B-R Roll Bar Brace Brackets

The (F-01432B-L and F-01432B-R) roll bar brace brackets were scuffed with a red ScotchBrite pad.

Deburring C-01433 Roll Bar Bushing Covers

There are four (C-01433) bushing covers. Time to start the debur process again.

Deburring C-01433 Roll Bar Bushing Covers

As you can see, the edges of these (C-01433) bushing covers are a little bit rough.


Deburred C-01433 Roll Bar Bushing Covers

It took a little while but the edge debur is complete on all four (C-01433) bushing covers as well as reaming and deburring all holes.

I scuffed all surfaces with a red ScotchBrite pad.

Cut Out Extra Material From F-14125 Skin Stiffeners

As per step one, figure one, on page 37-08 of the builder's manual, the excess material on the "tails" of the (F-14125) skin stiffeners needs to be removed.

The first thing to do is lay out the lines where the extra material needs to be removed from.

*If you take a close look at these skin stiffeners you will notice that one of them has a single hole drilled in the surface, this one will end up being the left (F-14125-L) skin stiffener...just a way to keep everything "straight" once the two pieces are separated.

Cut Out Extra Material From F-14125 Skin Stiffeners

I removed the excess material using the bandsaw.

Now it's time to start edge deburring. I started on the (F-14125-R) skin stiffener, (it's the one without the single hole on one side that I was talking about earlier), and then I final reamed and deburred all #40 holes.

F-14125-L and F-14125-R Skin Stiffeners

Here's another look at the (F-14125-L and F-14125-R) skin stiffeners. They have a slight curve to them.

*On page 37-08 of the builder's manual in step three and also in figure one there is a note that this curvature may need to be fluted as required in order to get a good alignment against the (F-01474-L and F-01474-R) side skins.


Scuffing F-14125-L and F-14125-R Skin Stiffeners

I scuffed all surfaces on the (F-14125-R) skin stiffener with a red ScotchBrite pad.

I edge deburred the (F-14125-L) skin stiffener, final reamed and deburred all #40 holes, and then scuffed all surfaces with a red ScotchBrite pad.

Dimpled F-14125-L and F-14125-R Skin Stiffeners

As per step two, figure one, on page 37-08 of the builder's manual, the #40 holes were dimpled on both (F-14125-L and F-14125-R) skin stiffeners.

*Be sure to pay attention to the note in figure one, on page 37-08 because it shows that the dimpled flush side of each of the skin stiffeners is to be on the side with all of the #40 holes in such a fashion that the flanges will be able to have the fuselage skin dimples nest inside of these dimples.

Deburring F-01431A-FR Roll Bar Frame

I edge deburred the (F-01431A-FR) roll bar frame.

This is thick material, .0580", so it's going to take awhile for each section of roll bar frame.


Scuffed F-01431A-FR Roll Bar Frame

I started to scuff the inner surface of the (F-01431A-FR) roll bar frame with 320 grit sandpaper after reaming and deburring all of the #30 and #40 holes.

*These surfaces seemed to have some sort of film on them and originally I thought it was that clear vinyl film that they talk about but it wasn't, I think it was just some slight oxidation or perhaps some lubricant from the bending and forming process that is why I start out with the 320 grit sandpaper, I follow up after sanding with a light scuffing with a red ScotchBrite pad.


Deburred F-01431A-FR Roll Bar Frame

This is the finished scuffed surface of the (F-01431A-FR) roll bar frame.

Deburring F-01431A-FL Roll Bar Frame

I started the edge deburring process next on the left forward (F-01431A-FL) roll bar frame.

You can see how rough the edges are on these frames. You can also see the film I was talking about.

Deburring F-01431A-FL Roll Bar Frame

This is the (F-01431A-FL) roll bar frame. First, I reamed and deburred all #30 and #40 holes.

Scuffing F-01431A-FL Roll Bar Frame

I usually start scuffing the inner surface of the roll bar frames, it just seems like it's the harder side to do and I want get it done first. This is the (F-01431A-FL) roll bar frame.
I start out with 320 grit sandpaper and finish up with a light scuffing with a red ScotchBrite pad.


Scuffing F-01431A-FL Roll Bar Frame

This is the front side of that same roll bar frame. I finished scuffing the (F-01431A-FL) roll bar frame.


Scuffing F-01431A-FL Roll Bar Frame

Hard work! Doesn't look too bad! Now there are two more roll bar frames to go...


Scuffed F-01431A-FL Roll Bar Frame

Work begins on the right side, (F-01431A-AR) aft roll bar frame. I reamed and deburred all #30 and #40 holes.

*Eventually all of the #40 holes are going to be resized to #30 during the inboard and outboard roll bar strap fitting process. (See step six, on page 37-03 of the builder's manual.)

Deburring F-01431A-AR Roll Bar Frame

The part number stickers are kind of tough to remove but I found that if you wet them down with acetone and then scrape them off with a wooden wedge they come right off and cleanly without any scratches.


Scuffing F-01431A-AR Roll Bar Frame

Just like usual, I started scuffing the inner surface of the right, aft (F-01431A-AR) roll bar frame with 320 grit sandpaper and finish up with a light scuffing with a red ScotchBrite pad.

Scuffing F-01431A-AR Roll Bar Frame

This is the outer side of the right, aft (F-01431A-AR) roll bar frame.

Deburring F-01431A-AL Roll Bar Frame

This is the left, aft (F-01431A-AL) roll bar frame and although I reamed and deburred the #30 and #40 holes, I noticed that there may be a problem with this piece...

Deburring F-01431A-AL Roll Bar Frame

Yep, it's definitely the (F-01431A-AL) roll bar frame but there is a problem.


Problems With F-01431A-AR Roll Bar Frame

There are four indentations on the inner side of the aft, left (F-01431A-AL) roll bar frame and four dents on the outer surface of the frame.

Dents

The first two indentations aren't too bad and were 1/16" in diameter and about .0025" deep.

The third indentation, which you see on the left, in this photograph is about 1/8" with an oval shape about .0025" deep, but the indentation on the right side of this photograph is the largest, about 5/32", oval shaped and .0058" deep.

*This last indentation is within the maximum 10% depth of the material thickness allowed.
I am going to ask Van's Aircraft about this...

Dents

This is a closeup of one of the first two smaller indentations that I was describing earlier.

Van's Aircraft was great about handling this problem, they said that I could have the part replaced and the new (F-01431A-AL) is on it's way!

Way to go Van's!!

Deburring C-01432 Bushing Doublers

While I am waiting for the (F-01431A-AL) roll bar frame to arrive from Van's I am going to start on the (C-01432) bushing doublers.

Deburring C-01432 Bushing Doublers

The edges are kind of rough.

Deburred C-01432 Bushing Doublers

I edge deburred the four (C-01432) bushing doublers.

I also final reamed and deburred all #30 holes.


Scuffed C-01432 Bushing Doublers

I scuffed all the surfaces of the (C-01432) bushing doublers with a red ScotchBrite pad.

Deburring F-01431D Window Shims

Time to start on the two (F-01431D) window shims.

These are thin strips and will eventually be located on the top outer surface of the aft roll bar assembly. One window shim strip runs along the left side of the aft roll bar assembly up to the center and the other window shim strip runs along the right side of the aft roll bar assembly up to the center. The rear window will eventually be attached to these shims.

Deburring F-01431D Window Shims

I edge deburred one of the two (F-01431D) window shims.

I reamed and deburred all holes on both (F-01431D) window shims.

Scuffed all surfaces on the first window shim with a red ScotchBrite pad.


Deburred F-01431D Window Shims

I scuffed all surfaces on the first window shim with a red ScotchBrite pad.

Next, I started on the edge deburring of the second of the two (F-01431D) window shims.

I scuffed all surfaces with a red ScotchBrite pad.

Deburring Inner And Outboard Roll Bar Straps

I am working on the (F-01431B and F-01431C) outboard and inboard roll bar straps next.

I started out by reaming and deburring all #40 holes of the (F-01431B) outboard roll bar strap and the (F-01431C) inboard roll bar strap.

Deburring Inboard And Outboard Roll Bar Straps

The (F-01431B) outboard roll bar strap is the longer of the two parts, it is 75 3/8" long. The (F-01431C) inboard roll bar strap is shorter and is 66 1/8" long.

These two straps are used to join the individual roll bar frames together.

Deburring Inboard F-01431C Roll Bar Strap

I began edge debur on the shorter (F-01431C) inboard roll bar strap.

*I like to set up a jig that I can clamp the straps to so that the edges will remain rigid while I am filing the edges, it also allows me to use both hands. These straps are long and would just "flop around" if you didn't have some way to hold them upright while working on them.
I just use a piece of aluminum angle to clamp the pieces to.

Deburring Inboard F-01431C Roll Bar Strap

Nice!

Rough Edges

This is what the edge of the roll bar strap looks like up close.


Deburring Inboard F-01431C Roll Bar Strap

I finished the edge debur of the (F-01431C) inboard roll bar strap.

I also scuffed all surfaces with a red ScotchBrite pad.

Smooth Edge

Smoooth!


Deburred And Scuffed Outboard F-01431B Roll Bar Strap

Same treatment for the outboard roll bar strap.
I edge deburred the (F-01431B) outboard roll bar strap and scuffed all surfaces with a red ScotchBrite pad.


Replacement Roll Bar Frame

The replacement (F-01431A-AL) roll bar frame arrived today..."cudos" to Van's Aircraft for replacing the defective one so quickly.

F-01431A-AL Roll Bar Frame

As you may recall, the original had some indentations and dents in it but this one looks okay!

4027 Aluminum

I reamed and deburred all of the holes and began the edge deburring process.

Can you see the AMS 4027 stamped on the outer surface of the aluminum? This is tempered T6 material and it is tough!
I don't know what they use to paint this on with or if there is a clear coating, but it won't come off with acetone, lacquer thinner, alcohol, or with a heat gun so it's just going to have to come off with light sanding and red ScotchBrite pads.

Reamed Deburred Scuffed Inner Roll Bar Frame

I usually start the scuffing process on the inner half of the roll bar frame.


Scuffed Outer Roll Bar Frame

The outer part of the (F-01431A-AL) roll bar frame gets scuffed last.


Torqued Fuel Lines

I final installed the individual fuel lines in the inner fuselage section and torque set them at 75 inch/pounds when I was able to get at them with a torque wrench and a crow's foot attachment, and when the torque wrench was too long I used a stubby open end wrench and the 1/4 flat method to torque them.

This is the (F-14109C) pump-firewall fuel line.

After final torque setting, I marked the fittings with yellow torque seal.

*You will find that most of the fittings will require using a 11/16" stubby wrench.

Don't use any thread sealant or loctite on these joints!

Quarter Flat Chart

Here is the 1/4 flat chart in case you can't find it on the Van's Aircraft website.

Torqued Fuel Lines

This is where the (F-14109C) pump-firewall fuel line and the (F-14109B) valve-filter fuel line connect to the (FUEL-FX375-MK) fuel filter and the (ES-PX375-TC) fuel pump.

Torqued Fuel Lines

This is where the (F-14109B) valve-filter fuel line connects to the (FUEL-FS20X2-T) fuel selector valve.

Torqued Fuel Lines

This is where the (F-14109A-L) fuselage side-valve fuel line and the (F-14109A-R) fuselage side-valve fuel line connects to the (FUEL-FS20X2-T) fuel selector valve.

Torqued Fuel Lines

This is where the (F-14109A-L) fuselage-side valve fuel line connects to the (AN833-6D) fuel fitting elbow.

Torqued Fuel Lines

This is where the (F-14109A-R) fuselage-side valve fuel line connects to the (AN833-6D) fuel fitting elbow.

Torqued Fuel Lines

After I got the fuel lines attached and torqued I started to install the outer half of the individual (F-01498B) fuel line brackets. I ran into a problem because a standard length phillips screw driver will not fit in between the spaces of the (F-01438) cover ribs. I am going to have to get a shorter screw driver to finish the job.


Scuffed Inner Roll Bar Frame

After I finished scuffing the (F-01431A-AL) roll bar frame, I cleaned all of the roll over structure parts with acetone in preparation for priming.

Cleaned Roll Bar Parts

These are all of the individual parts waiting to be primed: (F-01431A-AL, F-01431A-AR, F-01431A-FL, F-01431A-FR, two F-1231E, F-14125-R, F-14125-L, F-01432B-R, F-01432B-L, four C-01432, four C-01433, and F-01432A).

Primed Roll Bar Parts

I primed the parts with DupliColor self etching DAP 1690 green primer but only in the locations that they will be touching each other during the assembly process. Final priming will be done after everything is assembled.


Masked Roll Bar Frame For Priming

I just masked off the area on the (F-01432A) roll bar brace where the (F-01432B-L and F-01432B-R) roll bar brace brackets were going to be riveted together.

Clecoed Brace Brackets To Roll Bar Brace

After the paint had dried, I clecoed the (F-01432B-L and F-01432B-R) roll bar brace brackets to the (F-01432A) roll bar brace in preparation for riveting.

Clecoed Brace Brackets To Roll Bar Brace

Here's another view.

*Be careful how you orient the brace brackets because there is a right one and a left one....don't want to get these backwards!

Riveted Brace Brackets To Roll Bar Brace

I used our pnuematic squeezer to set the twenty four AN470AD4-4 rivets called for in figure two, on page 33-04 of the builder's manual.

Riveted Brace Brackets To Roll Bar Brace

Here is what it looks like when riveted.

Riveted Brace Brackets To Roll Bar Brace

The squeezer does a nice job.

Primed Roll Bar Frame Joint Areas

The (F-01431A-AL, F-01431A-AR, F-01431A-FL, and F-01431A-FR) roll bar frames got primed at the tops where the two (F-1231E) roll bar splice plates will be attached.

Number 12 Drill Bit

Step one, on page 33-04 of the builder's manual, calls for all of the holes in the rudder pedal bars to be final drilled with a #12 drill bit.

Final Drill Holes In Rudder Pedal Bars

These are the (WD-655-L and WD-655-R) rudder pedals that they are referring to, they are powder coated in white.

WD-655-R And WD-655-L Rudder Pedal Bars

Rudder pedal bars.

Final Drilling Holes In Rudder Pedal Bars

I final drilled and deburred the eight holes, per rudder pedal bar, with a #12 drill bit.

*Don't forget to drill out the holes in the small tabs at the top of the rudder pedals, they are easy to overlook!

After I drilled the holes I removed the parts stickers and labeled each rudder pedal with a "L" or "R".


Deburr Edges Of Rudder Pedal Bars

As per step five, on page 33-05 of the builder's manual, the end faces of the (WD-655-L and WD-655-R) rudder pedals need to be deburred and lightly sanded.

Polished Ends Of Rudder Pedal Bars

Since these areas are going to be bearing surfaces I also polished the ends.

Polished Ends Of Rudder Pedal Bars

The ends will receive some Aeroshell #5 grease, or equivalent, later on when they are attached to the fuselage.

Polished Ends Of Rudder Pedal Bars

This is the (WD-655-L) left rudder pedal, the right side will get the same treatment.


Standard Plastic Brake Lines Can Leak

This is a photograph of someone's leaking plastic brake lines, this is on a RV6.

*If you landed here from where I first installed the standard brass elbows on the landing gear braces, click here to return to where you were.

Aircraft Specialty Flight Lines makes pre-fabricated brake line hoses and fuel lines for the RV14A and RV14....and other RV models as well. I decided that it was well worth the extra cost to have brake lines that weren't prone to leak so I purchased the standard brake line kit to install on our airplane.

Unboxed Aircraft Specialty Brake Hose Kit

This is what comes in the Cabin Hose Kit it has a 10 year free replacement warranty.

Fittings For Brake Lines

For the RV14A there are:
(10)- 90°-3 sized AN fittings
(1)- -3 sized AN Tee
(12)- (SB-500-6) snap bushings

Brake Lines

The stainless braided, pressure tested, conductive teflon hoses, with a clear vinyl protective cover contents are:
(1)- (F14116B-L) line labeled (R1 H4)
(1)- (F14116B-R) line labeled (R1 H3)
(1)- (F14116C-L) line labeled (R1 H6)
(1)- (F14116C-R) line labeled (R1 H5)
(1)- (F14116A-L) line labeled (R1 H1)
(1)- (F14116A-R) line labeled (R1 H2)

Parts Bags

These are the bags that you will find the hardware to assemble the (CS-00018-L and CS-00018-R) brake pedal assemblies to the (WD-655-L and WD-655-R) rudder pedals.

Parts To attach Brake Pedals To Rudder Pedal Bar

As per steps two and three, on page 33-04 of the builder's manual, Aeroshell #5 grease is applied to the bearing surfaces of the bolts that will be connecting the brake assembly to the bottom of the rudder pedal.

*Figure one on page 33-04 shows the forward, or firewall side, of the rudder pedal.
The hardware that is called out in figure one is shown in this photograph at the bottom and is where the brake assembly will be attached.

Be sure to take note that you may need to use different mixes of thin or thick washers to correctly install the brake assembly...I found this to be true.


*Make sure that you take note of the caution, on page 33-04, that the nuts and bolts are only to be tightened "finger tight" and NOT to use standard torque values here!

Top Attachment Brake Pedal To Rudder Pedal Bar

I also found that I had to slightly adjust the mounting tabs that the bolts go through, but only slightly, so don't use a rubber hammer! I used a piece of inner tube and a large cresent wrench to adjust them.

The construction is pretty good so you really won't have to adjust the tabs much.

This is the pilot's left rudder side, three more to go!

Brake Pedals Attached To Rudder Pedal Bars

All of the (CS-00018-L and CS-00018-R) brake pedal assemblies have been attached to the (WD-655-L and WD-655-R) rudder pedals.

Brake Master Cylinders

These are four Matco brake master cylinders (MC-4F) that will be attached to the brake pedal and rudder pedal assemblies.

Brake Master Cylinders Labeled

I labeled each of the Matco (MC-4F) master brake cylinders "L-1" or "R-1" so that I could keep the orientation of each one correct. (They will be either right or left depending on which rudder pedal you place them on.)

I marked reference lines on each of the master brake cylinders so that the individual -3 sized 90° AN fittings could be "clocked" to the proper position as illustrated in figure three, on page 33-04 of the builder's manual.

*The top -3 sized 90° elbows face up and are vertical and the bottom -3 sized 90° elbows are clocked 8° from vertical and face up to either the right or left, which is dictated by which pedal you place them on.


Loctite 567 Thread Sealant

As per step four, on page 33-04 of the builder's manual, thread sealant is to be applied to the NPT side of the 90° elbow fitting before you insert them into the master brake cylinders. I used Loctite 567 thread sealant.

Clocked Elbow Fitting

This shows how the elbows should be "clocked".

This Matco (MC-4F) master brake cylinder will be attached to the left rudder pedal and the (F-1052B) side plate with the hardware shown and as described in figure two, on page 33-04.

*I tightened each elbow fitting to "finger tight" and then an additional 3/4 to a maximum of one turn past "finger tight".

If you look closely you can see the sharpie index marks that I used to keep the "clocking" correct.

Close Up Brake Pedal Attachment

Aeroshell #5 grease was applied to the bearing surface of the AN3-7 bolt I used to fasten the top of the Matco (MC-4F) brake master cylinder to the tab on the rudder pedal.

Close Up Brake Pedal Attachment

Here's a closer look, make sure to put the thin washers in the correct place.


Split Bushing

Just like when routing the wiring and the control cables in the empennage section, the snap bushings have to be split so that they can be slipped around the stainless steel end connectors, (which on these hoses are about 30/64" in diameter), and the hoses are 9/32" in diameter.

There are two different snap bushings that will be used when routing the hose lines through the inner fusealge areas, one is a (SB-750-10) and the others are the smaller (SB-500-6).

It looks like the standard pre-punched holes in the mid fuselage section will need to be enlarged from the original 3/8" openings to 1/2" but more on that later on when it comes time to install the hoses.


Master Cylinder Attached To Bottom Brake Pedal

Back to installing the bottom halves of the Matco (MC-4F) brake master cylinders to the (F-1052B) brake pedal side plates....

The hardware to be used is listed in figure two, on page 33-04 of the builder's manual.

Master Cylinder Attached To Bottom Brake Pedal

Aeroshell #5 grease was applied to the bearing surface of the AN3-12 bolt before assembly and then everything was assembled as directed.

*Don't forget to pay attention to where the thin and thick washers go.

I also had to snug up the castle nuts on this part of the install somewhat because if they are too loose you can see a lot of "wobbling" when the pedal is deflected but if they are too tight there can be some binding. It's pretty intuitive, but make sure that you watch this area.


This is a left rudder pedal/brake pedal installation.

Master Cylinder Attached To Bottom Brake Pedal

Same technique goes for the right side.

Master Cylinder Attached To Bottom Brake Pedal

This is a closeup of the right rudder pedal/brake pedal installation.


Flap Actuation Parts

These are the parts that will be used to make up the flap actuation system. There is one (WD-1013A) flap crank, two (CS-00010) torque arms, and a (W-00026) alignment template.

Flap Crank

The (WD-1013A) flap crank is powder coated and needs to have the ends deburred before anything begins.

Drilling Attach Points

As per step one, on page 34-02 of the builder's manual, the attachment points of the (CS-00010) torque arms and the (WD-1013A) flap crank need to be opened up with a 1/4" drill bit to clear excess powder coating.

CS-00010 Torque Arm

This is the (CS-00010) torque arm and the attachment point that needs opened with the 1/4" drill.

WD-01013A Flap Crank

This is the (WD-1013A) flap crank and the attachment point that needs opened with the 1/4" drill.

While I was at it, I also reamed the #30 holes because they had some powder coating in them too.

File Flap Crank Tubes

As you can see, the flap crank tubes need to be filed to smooth out the powder coating.

Filed Flap Crank Tubes

The flap torque arms will be attached here so it's nice to have these edges smoothed and also there will need to be some sanding inside the tube for a nice fit of those flap arm torque tubes.

Flap Torque Arm Tube Ends

The ends of the (CS-00010) flap torque arm tubes will fit better if they have the edges "dressed up".

Sand Edges Of The Flap Torque Arm

As per step three, on page 34-03 of the builder's manual, the (CS-00010-L and CS-00010-R) inboard powder coated edges need to be "feather edge sanded".

Since this area is going to be "riding" in a bearing block, I think I might even polish these somewhat a little later....


Flap Position Sensor

Since I am working on the (WD-1013A) flap crank and I have also received the 14 FLAP POSITION KIT, now would be a good time to drill a #30 hole in the left side of the flap crank as per the instructions in step three, on page 54-02 of the builder's manual.
The hole was drilled 3 21/32" from the edge of the attachment hole as shown in figure two and then deburred.

*If you don't drill this hole now and wait until after the flap actuation parts are installed in the fuselage you will have to tear everything apart in order to get back at the (WD-1013A) flap crank in order to drill the #30 which is where the (F-14127) flap position pushrod is attached.

Flap Position Pushrod Hole

I wouldn't want to have to tear everything apart to get this #30 hole drilled.....probably would just have to look out the window to see where the flaps were at!

Rigging The Flap Actuator Torque Arms

As per step two, page 34-02, and referring to figure one in the builder's manual, the (WD-1013A) flap crank was clamped to our long flat back rivet plate.
The (CS-00010) flap torque arm was inserted into the (W-00026) alignment template and secured with the hardware called out in figure one.

Alignment Template

This is the (W-00026) alignment template

Hardware For Alignment Template

I found the hardware to attach the (W-00026) alignment template in bag 3352.

Rigging The Flap Actuation System

The (CS-00010) flap torque arm was then inserted into the (WD-1013A) flap crank with the (W-00026) alignment template sitting flat against the back rivet plate per figure one, on page 34-02 of the builder's manual.

*Make sure that the (CS-00010) flap torque arm is positioned 23 5/16" laterally from the edges of the flanges of the (WD-1013A) flap crank and the (CS-00010) flap torque arm as shown in figure two, on page 34-02 of the builder's manual!

Match Drilling CS-00010 Flap Torque Arms

As per step six, on page 34-02 of the builder's manual, #30 holes were match drilled into the (CS-00010) flap torque arm using the pre-drilled holes in the (WD-1013A) flap crank as guides, as shown in figure one, with clecos inserted into the holes as drilling progressed.

Match Drilling CS-00010 Flap Torque Arms

A hole on the opposite side of the assembly was #30 match drilled and a cleco inserted.

*With at least two holes match drilled and clecoed together it is now possible to remove the clamps holding the assembly together in order to match drill #30 the remaining two holes as per step eight, page 34-02, figure three, of the builder's manual.

Match Drilling CS-00010 Flap Torque Arms

The remaining two holes were match drilled with a #30 bit and clecos were inserted.

As per step nine, on page 34-02 of the builder's manual a #12 hole was final drilled all the way through the holes on both sides of the (WD-1013A) flap crank and the (CS-00010) flap torque arm and a AN3-14A bolt was inserted in order to final #12 drill the last two holes remaining.

Match Drilling CS-00010 Flap Torque Arms

The #12 hole was drilled all the way through.

Labeled Flap Torque Arm

After the (WD-1013A) flap crank and the (CS-00010) flap torque arm were completely final #12 drilled, I disassembled the assembly and deburred all of the holes.

The flap torque arm was labeled "C10L" for the (CS-00010-L) left flap torque arm.


Match Drilling The CS-00010-R Flap Torque Arm

The (CS-00010-R) right flap torque arm is a mirror image of the (CS-00010-L) left flap torque arm.

Steps 1-11, on page 34-02 of the builder's manual, need to be completed in order to fabricate the right flap torque arm.

Fabricating The Right Flap Torque Arm

Everything has been clamped in place, the (W-00026) alignment template is attached to the (CS-00010) flap torque arm and is sitting flat against the back rivet plate, time to start #30 match drilling!.....

Fabricating The Right Flap Torque Arm

Cleco each hole as you go....don't forget about the lateral spacing, 23 5/16" laterally from the flanges of the (WD-1013A) flap crank and the (CS-00010) flap torque arm...

Fabricating The Right Flap Torque Arm

Once the first two #30 holes have been drilled and clecoed, the assembly can be unclamped from the back rivet plate and the remaining #30 holes are match drilled and clecoed.

Fabricating The Right Flap Torque Arm

An AN3-14A bolt is inserted into the two opposite holes of the (WD-1013A) flap crank and the (CS-00010) flap torque arm after they have been final #12 drilled.

Final Drilled CS-00010-R Flap Torque Arm

The remaining two holes of the (WD-1013A) flap crank and the (CS-00010) flap torque arm have been #12 final drilled.

The assembly is disassembled and all the holes are deburred.

Label The Right CS-00010-R Right Flap Torque Arm

The right flap torque arm has been labeled "C10R" for (CS-00010-R).


Makeshift Chair

I made a "makeshift" chair so that I can get an idea how far forward or aft I want to set the rudder pedals, (there are three positions)...I haven't ordered the finish kit yet so this chair will have to do for now!

Installing Fuel Line Brackets

I still have to install the remaining halves of the (F-01498B) fuel line brackets, there are four brackets per aircraft side and some of the spaces are really tight to get to but I found this offset screw driver set from Harbor Freight so let's give it a try. It has a ratchet built in and different sized hex bits.

Turns out that this screw driver set worked out great and it's super cheap!

Fuel Line Brackets

These are the four (F-01498B) fuel line brackets that were attached on the left fuselage side.

Fuel Line Brackets

These are the four (F-01498B) fuel line brackets that were attached on the right fuselage side.

Brake Lines

As per step one, on page 33-07 of the builder's manual, a tee fitting needs to be attached to the cockpit side of the (VA-107) brake fluid reservoir.

We are substituting all of the brake lines in our airplane with Aircraft Specialty components and so I am installing the -3 sized AN tee supplied with the kit.

Brake Line Tee

This is the -3 sized AN tee fitting supplied by Aircraft Specialty.

Brake Line Tee

Loctite 567 thread sealant was applied to the NPT side of the -3 Sized AN tee and then it was attached to the (VA-107) brake fluid reservoir.

Brake Lines

Aircraft Specialty labeled the replacement for (F-14116A-L) as R1 H1, it is the brake line with a 90° fitting on the end. I attached it "finger tight" for now.

The replacement for (F-14116A-R) is labeled R1 H2, I attached it to the end of the -3 sized AN tee "finger tight" for now.


Polished Flap Torque Arms

I polished the surfaces of the (CS-00010-L and CS-00010-R) flap torque tube arms that will be sitting inside of inboard (F-1030 INBD) blocks.

Rubber Stopper

The insides of the flap torque arms need to be primed so I got these 7/8" rubber stoppers to plug up the ends of the tubes while I swirl primer inside them....don't forget to tape over the #12 holes!

Priming CS-00010 Flap Torque Arms

This how I primed the insides of the (CS-00010-L and CS-00010-R) flap torque arms.

I used PTI GPHOS enamel camouflage gray primer.

Primed CS-00010 Flap Torque Arms

Watching paint dry!


Flap Linear Actuator

As per step three, on page 34-04 of the builder's manual, the ES 85615-10 linear actuator extension shaft needs to have a .063" (#52 drill bit) hole drilled at an angle through the lip of the shaft and near the jamb nut so that safety wire can be threaded through it.

Safety Wire Hole

This is figure two on page 33-04 that shows the angle that the drilled hole needs to be.

*Be sure to take note that the removal of the jamb nut and the rod end needs to be avoided because the length and setting has been set at the factory.

Number 52 Drill Bit

This is the drill bit size to accomplish the task.

Safety Wire Hole

This is where the hole will be drilled.

Drilling Safety Wire Hole

Start out by drilling vertically down at the lip but slowly start to angle the drill to the approximate angle.

Safety Wire Hole Drilled

This is the hole after being drilled, I lightly deburred it.

Safety Wire

I plan on using .032" stainless steel safety wire to secure this joint (.041" safety wire will fit in the hole too). Six to eight twists per inch with a "pigtail" at the end of the wire.

Safety Wire

This is what the .032" safety wire looks like when threaded through the hole.

Flap Position Pushrod

As per step two, page 54-02 of the builder's manual, it's time to fabricate the (F-14127) flap position pushrod.

The pushrod is attached on the left side of the (WD-1013A) flap crank and also to an arm on the (ES MSTS POS-12) position sensor.

*The (ES MSTS POS-12) position sensor sends a signal to the Pilot Flight Display which gives visual reference as to flap position.

Flap Position Pushrod

Figure one, page 54-02 of the builder's manual, shows the dimensions that the (F-14127) flap position pushrod should meet. Basically there are two 90° bends at each end of the supplied (SSP-063) rod which will have an overall eight inch length.


Flap Position Sensor Electrical

Now to my favorite subject....electrical...NOT!

As per step one, on page 54-03 of the builder's manual, (ES-00047) micro molex pins need to be placed on the ends of the wires exiting the (ES MSTS POS-12) flap position sensor.

Stripping Tool

The wires are fairly lightly gauged so make sure you have a wire stripper capable of stripping wires lighter than 20 gauge.
I got this stripper at HD.

*I think the wires are 24 gauge. The Klein tool stripper can strip wires as thin as 32 gauge.

Flap Position Sensor Electrical

I strip the wire about 1/4", just enough to go through the (ES-00047) micro molex pin base.

Crimped Micro Molex Pin

I used a SteinAir SAT-018 Molex type/open barreled pin crimper to connect the (ES-00047) micro molex pins.

Here is where you can buy the SteinAir SAT-018

Label Flap Position Sensor Wires

I used some shrink wrap in our Dymo Label Manager to print and place a label on the wires before connecting the (ES-00047) micro molex pins.

Here is where you can buy the Dymo LabelManager 160

Connecting The Flap Position Sensor Wires to the Molex Plug

As per step two, on page 54-03 of the builder's manual, I inserted the micro molex pins into the (ES-00144) molex plug using figures one and two as a reference.

Shrink Wrap Wire Bundle

The last step was to use my heat gun to shrink wrap the label into place.

Cable Guides

In step seven, on page 33-12 of the builder's manual, there are four cable guides that need to be machine countersunk before they are riveted into place.

These cable guides are: (F-01497A) and (F-01479B).

Countersink Cable Guides

They need to be machine countersunk so that a 1/8" dimpled skin can fit inside. I use this #30 dimpled test piece as my depth gauge.

Countersunk Cable Guides

The (F-01497A) and (F-01479B) have been countersunk, they will be attach later to the (F-01451-L and F-01451-R) tunnel sides with AACQ4-3 rivets.


Rudder Pedal Bearing Blocks

These are the parts and hardware that will be used to attach the rudder pedal assemblies to the fuselage.

The two solid blocks are (F-1039A) bearing blocks and the split block is the (F-6115) bearing block.

The solid (F-1039A) bearing blocks use AN3-22A bolts to attach the (WD-655-L and WD-655-R) rudder pedal assemblies to the (F-01419-L and F-01419-R) stiffeners.

The split (F-6115) bearing block uses AN3-21A bolts to attach the (WD-655-L and WD-655-R) rudder pedal assemblies to the center (F-14104) support angle.

Dry Fit Rudder Pedal Assemblies To Fuselage

I "dry fitted" the (WD-655-L and WD-655-R) rudder assemblies and rudder pedal blocks to the fuselage to check for proper alignment as per figures four, on page 33-05, and figure one, on page 33-06 of the builder's manual.

I found that the top half of the (F-6115) bearing block was too thick to fit under the (F-14104) support angle as seen in figure one, on page 33-06 of the builder's manual.
I marked the proper height required on the bearing block with a silver sharpie so that it can be trimmed for a proper fit.

I will trim the upper half of the (F-6115) bearing block with our stationary sander.

Enlarge Brake Line Passage Holes

The holes that the new Aircraft Specialty brake lines pass through in the seat ribs and through the forward and aft center section bulkheads need to be enlarged from .375" to .50" due to the size of the brake line end fittings.

The red arrows show the passage ways that I am referring to.
I enlarged all of the holes using a 1/8"-1/2" hex-end unibit in a 90° flex shaft adapter for my hand drill.
The process is easy to do and doesn't take much time. After enlarging the holes I deburred them.

Unibit

This is the unibit that I used, you might need an extension as well. I got both of these at HF for less than $10!

Enlarge Brake Line Passage Holes

Here is another view of the enlarged holes through the seat ribs.

Because the holes are larger (SB-500-6) snap bushings will have to be used to protect the brake lines where they pass through the structure but they are included in the Aircraft Specialty brake line conversion kit.

Enlarge Brake Line Passage Holes

The holes that passes through the (F-01403) forward center section bulkhead and the (F-01404) aft center section bulkhead have to be enlarged. Only the bottom hole on each side of the center section bulkheads are to be enlarged so that means there will be a brake line running along the left and right side of the center tunnel until they join further forward near the rudder pedal assemblies.

This is the (F-01404) aft center section bulkhead.

Enlarge Brake Line Passage Holes

These are the two holes I was talking about. This is the (F-01403) forward center section bulkhead assembly.

Enlarge Brake Line Passage Holes

The space between the forward and aft center section bulkheads is narrow, that is why you might need the hex bit extension for the hex bit unibit.

Installing Brake Lines

Time to install the brake lines!

The new left center brake line was installed from the (U-01402) lower landing gear brace, through the seat ribs, through the aft and forward center section bulkheads, over the (F-14101) routing channel (in the center tunnel) up to the master cylinders.

Snap bushings (SB-500-6) were installed where the brake line passes through the structures.

This is the left fuselage brake line (R1 H6) it replaces the original (F-14116C-L) brake line.

Installing Brake Lines

Here you can see where the two brake lines (R1 H6 and R1 H5) meet forward just aft of the master cylinders.

Installing Brake Lines

The new right center brake line was installed from the (U-01402) lower landing gear brace, through the seat ribs, through the aft and forward center section bulkheads, over the (F-14101) routing channel (in the center tunnel) up to the master cylinders.

Snap bushings (SB-500-6) were installed where the brake line passes through the structures.

This is the right fuselage brake line (R1 H5) it replaces the original (F-14116C-R) brake line.

Left Brake Line Tag

This is the tag on the left center brake line (R1 H6).

Right Brake Line Tag

This is the tag on the right center brake line (R1 H5).


Trim Bearing Block

The (F-6115) upper center bearing block doesn't fit under the (F-14104) support angle as it should so I marked it with a silver sharpie when it was temporarily installed in the fuselage.

Now it is time to trim the excess material from the block in order to achieve a proper fit. I trimmed about 5/32" off the top surface using our stationary sander so that it will fit under the (F-14104) support angle.

Trim Bearing Block

Here you can see the difference in thicknesses between the upper and lower bearing blocks.

Trim Bearing Block

Everything fits as before except with a lower profile.

*When I reinstalled the (WD-655-L and WD-655-R) rudder pedal assemblies the center (F-6115) bearing block fits perfectly under the (F-14104) support angle!


Cheezy Photo Op

Just couldn't help it, a cheezy photo op!

Cheezy Photo Op

Another cheezy photo op; we were sitting in the cockpit to determine which one of the three positions available for the rudder assembly installment that would suit us the best.
We chose the middle position.

AeroShell 5 Grease

As per step six, on page 33-05 of the builder's manual, AeroShell #5 grease (or equivalent) is to be applied to the bearing surfaces of the (WD-655-L and WD-655-R) rudder pedal assemblies before they are installed.

Rudder Pedal Installation

I put some AeroShell #5 grease into the (F-6115) bearing blocks too.

Rudder pedal Installation

The (WD-655-L and WD-655-R) rudder pedal assemblies were installed into the middle position choice as per step six through eight, on page 33-05 of the builders manual, and step one, on page 33-06 of the builder's manual, using the hardware called out in each of those sections.

*Be careful not to use standard torque values when tightening the nuts and bolts.


Control Stick

It's time to work on the control sticks for the airplane.
There are two (CS-00008) powder coated control sticks, they are alike but will eventually be created into a left and right control stick in the next steps.

Control Stick

As per step one, on page 36-10 of the builder's manual, an insertion point is marked at the lower end of what will become the left (CS-00008-L) control stick.

A mark is made 1/4" above the unpowder coated end, (which is 2 3/4" from the edge), as shown in figure one.

Control Stick

As per step two, on page 36-10 of the builder's manual, a 1/4" hole was drilled only on one side of the (CS-00008-L) control stick.
The hole was deburred after drilling.

*This is thick steel, especially when drilling through the control stick and the control stick base later, it might be a good idea to have several extra #12 and #19 bits handy; I broke three #12 drill bit tips on this part of the project.

The (CS-00008-R) right control stick is a mirror of the (CS-00008-L) left control stick.
I repeated steps one and two above, on page 36-10 of the builder's manual, to fabricate the right control stick.
As shown in figure two, on page 36-10, a 1/4" hole was drilled on one side and deburred on the (CS-00008-R) right control stick.

Control Stick Base

The (CS-00007-L and CS00007-R) control stick bases need to have the ends deburred, plus the pivot tube ends need to be smoothed.

Control Stick Base

As you can see, the ends need to have some powder coating filed off and the inner diameter needs to have powder coating sanded away from the pre-drilled holes so that the control sticks slide into the sockets easier.

Did I mention that this was thick steel?

Control Stick Base

There is some powder coating that need to be removed from the larger hole on the lugs too.


Control Stick Base

The edges of the (CS-00007-L and CS-00007-R) left and right control stick bases were deburred.
The pivot tubes of the (CS-00007-L and CS-00007-R) control stick bases have been filed smooth and polished.

*It's not necessary to polish the pivot tube ends, I just thought that since this is going to be a pivot point, it might have a smoother "action" if it were polished.

Control Stick Base
Control Stick Base
Control Stick Base

I labeled each control stick base with a sharpie in order to keep the correct orientation.

Control Stick Base

Control Stick Assembly

As per step four, on page 36-10, referencing figure three of the builder's manual, the (CS-00007-8-L) left control stick was inserted into the (CS-00008-L) left control stick base up to the 2 1/2" insertion mark.

The control stick assembly was laid onto a level, flat, and long back rivet plate with the (CS-00007-L) left control stick base sitting beyond the edge.

The (CS-00007-L) control stick base was rotated until it was level, as shown in figure three, on page 36-10.

A small dab of super glue was applied to temporarily hold the pieces in alignment in preparation for match drilling.

Control Stick Assembly

This is the super glue that I used.

*I'm not a fan of using the super glue alone. It does keep things aligned temporarily but as soon as the match drilling commences, the control stick base can rotate because the pressures are too great for the glue to hold anything steady.....there's got to be a better way!

Control Stick Assembly

I marked the two pieces with a sharpie so I could keep track of alignment and orientation.

Control Stick Assembly

I sliced a piece of inner tube about a 1 1/4" wide and about 10" long, then I wrapped it around the (CS-00008-L) control stick and (CS-00007-L) control stick base and then secured the inner tube tightly with a hose clamp.
I also used a dowel rod secured to a block of wood to further keep the control stick base from rotating.

A #19 hole was match drilled into the (CS-00008-L) control stick as per step six and then a #8 screw was inserted into the hole to further help hold parts in alignment.

The lower two holes were #19 match drilled into the (CS-00008-L) control stick and then #12 final drilled all the way through after which I inserted a AN3-14A bolt.

If I had to make control stick assemblies all day long, I would definitely want to build a proper jig to assure nothing moves but the inner tube/hose clamp solution worked pretty well and it was quick and easy to use...just use the super glue to hold everything in place while securing the inner tube.


Install HW-00008 Nylon Clamp

There is a (HW-00008) nylon clamp that snaps into a hole in the right side of the (F-14101) routing channel, in the center tunnel section of the fuselage. It was installed and the (R1 H5) right brake line was routed through it.

There was only one included in the original fuselage kit so I ordered another one from Van's Aircraft and will install it on the left side of the (F-14101) routing channel with the (R1 H6) brake line routed through it.

Removing Brass Elbow Fittings

I need to remove the brass (F69-F-04x02) elbows installed onto the (U-1402) lower landing gear braces in step two, on page 29-03 of the builder's manual.

I need to remove them in order to install the new -3 sized AN 90° elbow fittings from Aircraft Specialty.

Removing Brass Elbow Fittings

I removed the brass (F69-F-04x02) elbows.

The old thread sealant must be removed from the threads and around the edge of the hole.

Clean Thread Sealant

I used acetone to remove the old thread sealant.

Installed Brake Line Elbow

The new -3 sized AN 90° elbow fitting to attach the Aircraft Specialty (R1 H6) brake line was installed onto the left (U-1402-L) lower landing gear brace.

The fitting was final torqued using the 1/4 flat method.

*Do not use thread sealant on the flared side of the brake fitting elbows!

Installed Brake Line Elbow

The new -3 sized AN 90° elbow fitting to attach the Aircraft Specialty (R1 H5) brake line was installed onto the right (U-1402-R) lower landing gear brace.

The fitting was final torqued using the 1/4 flat method.

*Do not use thread sealant on the flared side of the brake fitting elbows!

Installing Brake Lines

As per figure one, on page 33-07 of the builder's manual, the (R1 H1 and R1 H2) brake lines were attached to the upper -3 sized AN 90° elbow fittings on the right fuselage side master brake cylinders.

The fittings were final torqued using the 1/4 flat method.

*Do not use thread sealant on the flared side of the brake fitting elbows!

Installing Brake Lines

Aircraft Specialty brake lines labeled (R1 H3 and R1 H4) replace the original brake lines (F-14116B-L and F-14116B-R), these are cross over brake lines and they are being installed next.

Before installing the brake lines however, the (F-14104) support angle middle hole was enlarged enough to accept a second (SB-750-10) snap bushing, this is where the cross over brake lines will be routed through.

(R1 H3) brake line runs from the right fuselage, right brake master cylinder, lower -3 sized AN 90° elbow fitting, through the middle hole on the (F-14104) support angle to the left fuselage, right brake master cylinder, upper -3 sized AN 90° elbow fitting.

The fittings were final torqued using the 1/4 flat method.

*Do not use thread sealant on the flared side of the brake fitting elbows!

Installing Brake Lines

(R1 H4) brake line runs from the right fuselage, left brake master cylinder, lower -3 sized AN 90° elbow fitting, through the middle hole on the (F-14104) support angle to the left fuselage, left brake master cylinder, upper -3 sized AN 90° elbow fitting.

The fittings were final torqued using the 1/4 flat method.

*Do not use thread sealant on the flared side of the brake fitting elbows!

Installing Brake Lines

This is the routing of the cross over brake lines.

*For those of you with sharp eyes, you might notice that where the brake lines cross through the center (F-14104) support angle, they are in the aft most hole, this was before I opened up the middle hole of the support angle so the next photographs will show the cross over lines running through the middle hole.

Installing Brake Lines

The (R1 H5) brake line runs from the left fuselage, right brake master cylinder, lower -3 sized AN 90° elbow fitting, through the aft most hole of the (F-14104) support angle, through the right center tunnel, over the (F-14101) routing channel, through the forward and aft center section bulkheads, through the right fuselage seat ribs to the -3 sized AN 90° elbow fitting on the (U-01402-R) right lower landing gear brace.

The (R1 H6) brake line runs from the left fuselage, left brake master cylinder, lower -3 sized AN 90° elbow fitting, through the aft most hole of the (F-14104) support angle, through the left center tunnel, over the (F-14101) routing channel, through the forward and aft center section bulkheads, through the left fuselage seat ribs to the -3 sized AN 90° elbow fitting on the (U-01402-L) left lower landing gear brace.

The fittings were final torqued using the 1/4 flat method.

*Do not use thread sealant on the flared side of the brake fitting elbows!


Control Stick

As per step seven, on page 36-10 of the builder's manual, the remaining hole in the (CS-00007-L) left control stick base was #19 match drilled into the (CS-00008-L) left control stick.

The #19 hole was then #12 final drilled all the way through the top two set of holes and a AN3-14A bolt was temporarily attached.

Control Stick

The (CS-00008-R) right control stick is a mirror of the (CS-00008-L) left control stick so I am fabricating it next.

*There is a note that says that the (CS-00008-R) right control stick is only attached with one (AN3-14A) bolt so that it can be removed easier if you decide to remove the stick when carrying passengers, hardware to attach it is not included in the kit....I ordered the hardware because I intend to keep the stick in place.

Fabricating the (CS-00008-R) right control stick is done by repeating steps one through seven, on page 36-10 of the builder's manual. Keep in mind that everything is reversed and the insertion hole is drilled on the inboard side of the stick.

All holes were #19 match drilled into the (CS-00008-R) right control stick after making sure that the (CS-00007-R) right control stick base was level and secured.

Control Stick

This is what the setup looks like after securing the (CS-00007-R) in place with the super glue, inner tube and hose clamp, and dowel rod.

Control Stick

I'm match drilling the #19 holes using the pre-drilled holes in the (CS-00007-R) right control stick base as guides to drill holes into the (CS-00008-R) right control stick.

Control Stick

After the first hole has been #19 match drilled into the (CS-00008-R) right control stick, a #8 screw is inserted to help maintain alignment.


Control Stick

As per step eight, on page 36-10 of the builder's manual, one set of holes were #12 final drilled all the way through and then a AN3-14A bolt was inserted. The second set of holes were #12 final drilled and the second AN3-14A bolt was inserted.

Control Stick

As per step one, on page 36-11 of the builders's manual, the lugs on the (CS-00007-L and CS-00007-R) control stick bases were #12 final drilled as seen in figure one.

Both control stick assemblies were marked then disassembled and all the holes were deburred.

The bare metal that is exposed on the control stick assemblies was primed with Krylon MAXX 9188 white primer.
*The pivot tube ends on the (CS-00007-L and CS-00007-R) control stick bases were not primed.

Control Stick

Here are both of the (CS-00007-L and CS-00008-L) and (CS-00008-L and CS-00008-R) control stick assemblies.


Reprime Landing Gear Brace

Acetone dissolved the primer surrounding the area where the original brass brake line fittings were. I changed the old fittings to the new Aircraft Specialty elbow fittings and when I did that I had to clean off all of the thread sealant which exposed some of the metal around the fittings. It's time to re-prime the bare metal.

Reprime Landing Gear Brace

I primed the area around the brake line fittings with DupliColor DAP1690 self etching green primer. I used a brush to touch up the surface.

This is the left (U-01402-L) lower landing gear brace.

Reprime Landing Gear Brace

This is the re-primed area around the right (U-01402-R) lower landing gear brace.

Tie Wrap Brake Lines

As per step eight, page 33-08 of the builder's manual, tie wraps were attached to the left and right brake lines using figure one as a reference.

Power Module Install

In section 59, which is an optional modification of the circuit breaker panel, the builder has an option that positions the circuit breaker panel at an angle, which makes it easier to see the fuses or breakers.

Van's Aircraft sells the kit under the parts code: (14 Power Mod Install Kit).

I unpacked the Power Module Install Kit and here are the parts.

Power Module Install brackets

As with any other kit or part that is used on the airplane, after inventory comes the deburring process.

The edges of the (F-14188B-L and F-14188B-R) brackets were deburred and the #40 holes were final reamed.


Scuffed Power Module Brackets

The surfaces of the (F-14188B-L and F-14188B-R) brackets were scuffed with a red ScotchBrite pad in preparation for priming.

Deburr The Sub Panel Mount

The edges of the (F-14188A) sub panel were deburred and all of the holes in the sub panel were checked for size and deburred.

All of the surfaces of the (F-14188A) sub panel mount were scuffed with a red ScotchBrite pad in preparation for priming.

Nutplate Install On Power Module Brackets

There are three nutplates that need to be installed on each (F-14188B-L and F-14188B-R) bracket.
As per step one, on page OP 59-02 of the builder's manual, the #40 nutplate rivet holes were dimpled in order to receive AN426AD3-3.5 rivets.

Each power module bracket will recieve two K1000-06 nutplates and one MS21051-L06 nutplate; these were dimpled also.

*I used our hand squeezer equipped with a reduced diameter female dimple die to make the dimples and to avoid the center post on the nutplate.

Nutplate Install On power Module Brackets

The space is a bit limited at the corners where the MS21051-L06 nutplate goes, but I was easily able to get the hand squeezers into the corner in order to set the rivets.

Nutplate Install On Power Module Brackets

Let's set some rivets!

Nutplate Install On Power Module Brackets

The cleco clamp works well in this situation where the MS21051-L06 nutplate only has one hole to rivet, it easily held the nutplate in position while the rivet was set.


Splice Plate Riveted To Roll Bar Frames

Today we are working in our hangar at the airport.

As per step four, on page 37-02 of the builder's manual, the (F-01431A-FL and F-01431A-FR) roll bar frames were clecoed to the (F-01231D) roll bar bases and the (F-1231E) roll bar splices as shown in figure three.

The (F-1231E) roll bar splices get riveted to the roll bar frames with AN470AD4-5 rivets. I am using our pneumatic rivet squeezer to set the rivets.

Splice Riveted To Roll Bar Frame

The forward roll bar frame splice receives 24 AN470AD4-5 rivets.

Forward Roll Bar Frame

Now that the forward roll bar frame has received the roll bar splice and is riveted, the assembly is removed from the roll bar bases so that the aft roll bar frames can be put together.

Forward Roll Bar Frame

The Forward roll bar assembly.

Aft Roll Bar Frame Construction

As per step five, on page 37-02 of the builder's manual, the (F-01431A-AL and F-01431A-AR) roll bar frames were clecoed to the (F-01231D) roll bar bases and the (F-1231E) roll bar splice plate as shown in figure four of the manual.

*It's interesting to note here that since there is nowhere to cleco this frame to the aft of the (F-01231D) roll bar bases this assembly is being built in reverse. The right side of the assembly will actually be on the left fuselage side, when completed, and the left side of the assembly will be on the right fuselage side.

This whole assembly will be rotated laterally 180° when it gets joined later to the front roll bar half.

There are four holes that do not get riveted at this time.

Aft Roll Bar Frame Construction

*Take note here that the (F-01431A-AL and F-01431A-AR) roll bar frames are only clecoed to the top row of holes on the (F-01231D) roll bar bases.

Splice Plate Riveted To Aft Roll Bar Frame

There will only be 20 AN470AD4-5 rivets set at this time in this (F-1231E) roll bar splice plate.

Splice Plate Riveted To Aft Roll Bar Frame

I am using our pneumatic rivet squeezer to set these AN470AD4-5 rivets.

Setting Rivets In Roll Bar Splice Plate

All of the AN470AD4-5 rivets have been set.

Aft Roll Bar Assembly

If you look closely at the top corners of the center splice joint you can see the four rivet holes that don't receive rivets at this time.

This is where the sides of the (F-01432A) roll bar brace gets attached to the aft roll bar frame assembly later on.


Primed Power Module Parts

The (F-14188B-L and F-14188B-R) power module brackets and the (F-14188A) power module sub panel were cleaned with acetone and primed with DupliColor DAP 1690 self etching green primer.

Attaching Straps To Forward Roll Bar Frame Assembly

As per step three, on page 37-03 of the builder's manual, the (F-01431B) outboard strap was clecoed to the outboard flanges of the forward roll bar frame assembly as shown in figure one.

Attaching Straps To Forward Roll Bar Frame Assembly

*The (F-01431B) outboard strap nests below the outboard flanges but above the short center flange of the forward roll bar frame assembly as shown in figure one on page 37-03 of the manual.

Attaching Straps To Forward Roll Bar Frame Assembly

As per step four, on page 37-03 of the builder's manual, the (F-01431C) inboard roll bar strap was clecoed to the inside of the inboard flange of the forward roll bar frame assembly as shown in figure one.

Attaching Aft Roll Bar Frame Assembly To Forward Roll Bar Frame Assembly

The aft roll bar frame assembly was then fitted onto the forward roll bar frame assembly with the (F-01431C) inboard roll bar strap nesting inside the flanges of the aft roll bar frame assembly and clecoed in place.

*Make sure that the (F-01431B) outboard strap of the forward roll bar frame assembly is above the center flange "tab" of the aft roll bar frame assembly and put some clecos here to keep everything in alignment because the (F-01431D) window shims are going to be attached next.

Attaching Window Shims To Aft Roll Bar Frame Assembly

As per step five, on page 37-03 of the builder's manual, the (F-01431D) window shims were clecoed to the outer surfaces of the aft roll bar frame assembly and to the (F-01431B) outboard roll bar strap of the forward roll bar frame assembly.

Roll Bar Frame Assemblies Clecoed Together

This is what it looks like all clecoed together....there are at least a couple hundred clecos here!

Roll Bar Frame Assemblies Clecoed Together

Another view, I had enough #40 clecos but ended up having to order more #30 clecos because all of these #40 holes will have to be final drilled to #30 size!


Final #30 Drilling Roll Bar Frame Assembly Holes

Before I started final sizing all of the #40 holes in the roll bar frame assemblies, I got a fresh new 3/4"x 2'x 4' piece of MDF so that I was sure that I would be working on a flat surface, I also clamped the assembly to the MDF...don't want any twist in this roll bar!

As per step six, on page 37-03 of the builder's manual, I began to final #30 drill all of the #40 holes in the roll bar frame assembly, clecoing each hole as the final drilling progressed.

Final Drilling Roll Bar Frame Assembly

I used a 12" #30 drill bit to final drill the #40 holes, it came in handy and also prevented the chuck of the drill from hitting the clecos.

I had enough #30 clecos to do the outer half of the roll bar assembly but had to order more to finish up the inside half, I think I had to order 92 more to do the job...that's alot of clecos!


Routing Rudder Cables

While I was waiting for the #30 clecos to arrive I went out to our hangar to route the rudder cables and attach them to the rudder pedals.

This is the hardware called out in figure two, on page 33-12 of the builder's manual, that will be used to attach the (CS-00014) rudder cable ends to the tabs on the rudder pedals.

As per step one, on page 33-11 of the builder's manual, I installed (SB750-10) snap bushings in the (F-01430) baggage floor stiffener, (F-01405A) bulkhead bottom channel, forward flange of the (F-01447-L) baggage floor, and (F-01404A) aft center section bulkhead on the left side of the fuselage.

Sorry that I don't have any pictures of the snap bushing locations, they are all under the baggage bin floor and you have to feel around with your hand in order to find where to place them...kinda know where to put them but have to use "braille" to insert them!

After installing the snap bushings into place, the (CS-00014) rudder pedal was routed through the snap bushings just installed along the left fuselage side, through the (F-01403A) forward center section bulkhead and out through the slots in the (F-01451-L) left tunnel side.

Routing Rudder Cables

Sometimes things don't work out like you had planned.

This is the hardware called out in figure two, on page 33-12 of the builder's manual, to install as cable guides for the (CS-00014) rudder cable as it exits the (F-01451-L and F-01451-R) tunnel sides.....I thought I was going to be able to install it in this work session but nope, not today!

The polyethylene sleeve of the (CS-00014) rudder cable needs to be secured to the side of the (F-01451-L and F-01451-R) center tunnel with clamps and hardware shown in figure one, on page 33-11 of the manual.
The space available is extremely tight and I am going to have to figure out some kind of tool to help me get the nuts inserted because I can't get my fingers in far enough to start the lock nut onto the end of the bolt....it's a known "trouble spot" but I haven't found anyone's solution yet.

While I was in the (F-01451-L) left tunnel area I was able to insert a second (HW-00008) nylon clamp to the left side of the (F-14101) routing channel and routed the (R1 H6) brake line through it.


Routing Rudder Cables

As per step one, on page 33-11 of the builder's manual, I installed (SB750-10) snap bushings in the (F-01430) baggage floor stiffener, (F-01405A) bulkhead bottom channel, forward flange of the (F-01447-R) baggage floor, and (F-01404A) aft center section bulkhead on the right side of the fuselage.

After installing the snap bushings into place, the (CS-00014) rudder pedal was routed through the snap bushings just installed along the right fuselage side, through the (F-01403A) forward center section bulkhead and out through the slots in the (F-01451-R) right tunnel side.

Routing Rudder Cables

Here is where the (CS-00014) rudder cables exit the (F-01451-L and F-01451-R) left and right tunnel side slots.

I am still trying to figure out some kind of tool to help me install the hardware that clamps the polyethylene sleeves of the rudder cables to the center tunnel sides....I think I have an idea, now I have to fabricate the tool, stay tuned!


Final Drilling Roll Bar Frame Assembly

The #30 clecos arrived so now back to final drilling the roll bar frame assembly.

As per step six, on page 37-03 of the builder's manual, all of the #40 holes have been final #30 drilled and clecoed.


Fabricate Lock Nut Tool

As you may recall I need to fabricate a tool so that I can insert a MS21042-3 lock nut onto the end of an AN3-3A bolt in a very tight space.
The space is too tight to get your fingers in plus it is hard to even see the end of the bolt.

I am refering to the space between the side of the (F-01451-L and F-01451-R) center tunnel, under the tops of the(F-01438-L and F-01438-R) cover ribs, and the face of the (F-01435-L and F-01435-R) cover panels.

I thought that if I could create a pocket in a plastic dinner knife large enough to hold the MS21042-3 lock nut in place at the end of the AN3-3A bolt, I might be able to at least get the nut started and then finish the job with stubby wrenches. I hope that this will work, I have yet to try it out.

This idea did not work, the space is still too tight and there is no way to see what you are doing to get this properly lined up with the end of the bolt......Click here if you want to see what finally did work!

Fabricate Lock Nut Tool

I made the tool by heating up a clear plastic dinner knife with a heat gun and then placing the knife over the MS21042-3 lock nut, which is clamped in a vise. While the plastic is still hot I held a 3/8" box end wrench over the nut to create the "pocket" to hold it in. The plastic cools off and retains the shape of the lock nut and is quite rigid.
I hope it works!

This idea did not work, the space is still too tight and there is no way to see what you are doing to get this properly lined up with the end of the bolt......

Countersinking Holes In Roll Bar Frame

As per step two, on page 37-04 of the builder's manual, I machine countersunk the #30 holes in the outboard flanges of the forward roll bar frame assembly to accept the head of an AN426AD4-5 rivet.

*Be careful not to machine countersink the holes indicated in figure one and two on page 37-04. These holes are the six holes at the base of each side of the roll bar frame assembly where they attach to the (F-01231D) roll bar bases and the aft four holes at the top center of the assembly where they attach to the (F-01432A) roll bar brace.

Countersinking Holes In Roll Bar Frame

As per step three, on page 37-04 of the builder's manual, the top six holes in the (F-01431B) outboard roll bar strap need to be countersunk to accept the #30 dimpled skin of the (F-01432A) roll bar brace as shown in figure two.

*Remember, the aft four holes do not get countersunk.

#30 Dimpled Skin gauge

I used this #30 dimpled skin as my gauge.

Six Countersunk Holes In Top Roll Bar Frame Assembly

These are the six holes in the (F-01431B) outboard roll bar strap that were countersunk to accept a #30 dimpled skin.


Countersinking Roll Bar Frame Assembly

As per Step two, on page 37-04 of the builder's manual, I finished machine countersinking the #30 holes on the outboard flange of the forward roll bar frame assembly.

I used the long extension on our hand deburr tool and used a #30 piloted countersink bit to complete the task; I feel I have more control using the hand countersink tool especially in areas like this roll bar where there are uneven surfaces like you have with the window shims clecoed in place next to the holes that are being countersunk.


Countersinking Roll Bar Frame Assembly

I must have misread the plans because I machine countersunk the #30 holes in the inboard flange of the forward roll bar frame assembly to accept the head of an AN426AD4-5 rivet.
If you look carefully at figure one, on page 37-04 of the manual, an AN470AD4-5 rivet is supposed to be used in this area.

Countersinking Roll Bar Frame Assembly

I machine countersunk the #30 holes in the inboard flange of the forward roll bar frame assembly in the same manner as I did the #30 holes in the outboard flange of the forward roll bar frame assembly.

Countersinking Window Shims In Aft Roll Bar Assembly

The (F-01432D) window shims are attached to the aft roll bar assembly with CS4-4 blind rivets.
These rivets require a countersink because they will be flush to the surface when installed.

Countersinking Window Shims In Aft Roll Bar Assembly

As per step four, on page 37-04 of the builder's manual, I am machine countersinking all of the #30 holes in the (F-01432D) window shims to accept the head of a CS4-4 rivet.

I flipped the roll bar assembly over so that the window shims are on the top to make it a little easier to access each #30 hole.

Countersinking Window Shims In Aft Roll Bar Assembly

The CS4-4 rivet head sits flush when seated properly in the countersunk hole.

There is a small .063" hole between each set of #30 holes, this will be used later to install the canopy and hold it in place with screws, nothing is done with it at this time.

Countersinking Window Shims In Aft Roll Bar Assembly

The countersink is almost as deep as that of a solid rivet.


Label Roll Bar Parts

As with any drilling holes the next thing to be done is deburring them.
Before taking everything apart I label the parts so that they can be put back together in their original orientation.

This is the (F-01431B) right bottom half of the outboard roll bar strap.

Label Roll Bar Parts

This is the (F-01431C) left bottom half of the inboard roll bar strap.

Label Roll Bar Parts

This is the (F-01431B) top center portion of the outboard roll bar strap.

Label Roll Bar Parts

This is the (F-01431C) top center portion of the inner roll bar strap.

Label Roll Bar Parts

This is the (F-01431B) left bottom half of the outboard roll bar strap.

This is the (F-01431D) left bottom half of the window shim.

Label Roll Bar Parts

This is the (F-01431D) top center half of the left window shim.

Label Roll Bar Parts

This is the (F-01431D) right bottom half of the right window shim.

Clean Roll Bar Parts For Painting

All of the parts were disassembled, the holes deburred, and the surfaces cleaned with acetone in preparation for priming.


Priming Window Shims

I masked the outer halves of the (F-01431D) window shims and primed the inner halves with DupliColor DAP 1690 self etching green primer.

I shortened the labeling to "ARB" which stands for Aft Right Bottom.

Primed Window Shims

Both (F-01431D) window shims have been primed.


Priming Roll Bar Parts

The aft roll bar frame assembly is cleaned with acetone and ready for priming.

I am only going to prime the inner half of the roll bar because I intend to prime the entire outer structure after everything has been riveted together.

Priming Roll Bar Parts

I primed the inner aft roll bar frame assembly with DupliColor DAP 1690 self etching green primer.

Priming Roll Bar Parts

I primed the inner forward roll bar frame assembly with DupliColor DAP 1690 self etching green primer.

Priming Roll Bar Parts

The (F-01431B) outboard roll bar strap and (F-01431C) inboard roll bar strap have been cleaned with acetone in preparation for priming.


Primed Roll Bar Straps

The inner halves of the (F-01431B) outboard roll bar strap and (F-01431C) inboard roll bar strap have been primed with DupliColor DAP 1690 self etching green primer.

Primed Bushing Doublers

I primed sections of the (F-01432) bushing doublers that will be in direct contact with the (F-01433) bushing covers with DupliColor DAP 1690 self etching green primer.


Assembling Roll Bar Structure

As per step five, on page 37-04 of the builder's manual, the (F-01431B and F-01431C) roll bar straps were clecoed to the forward roll bar frame assembly.

Assembling Roll Bar Structure

There are certain holes that do not receive rivets yet as shown in figures one and two on page 37-04 of the manual, so I marked them with masking tape so that I didn't accidentally rivet them.

The top center rows do not get riveted yet.

Assembling Roll Bar Structure

The bases don't get riveted yet either.

Riveting Roll Bar Structure

I started out near the top outer center of the forward roll bar frame structure and used our pneumatic rivet squeezer to attach the (F-01431B) outboard roll bar strap to the frame assembly with AN426AD4-5 rivets.

My riveting "plan of attack" is to alternately rivet from outer to inner and from left to right of center radiating outwards towards the bottoms of the forward roll bar frame assembly.

Riveting Roll Bar Structure

Riveting progressed smoothly but I ran out of AN426AD4-5 rivets, so I have to order more and wait for them to arrive before continuing.


Riveting Roll Bar Structure

The new order of AN426AD4-5 rivets arrived within 24 hours so on with the riveting!

As per step five, on page 37-04 of the builder's manual, I continued to rivet the (F-01431B) outboard roll bar strap and the (F-01431C) inboard roll bar strap to the forward roll bar frame assembly with AN426AD4-5 rivets set with our pneumatic rivet squeezer.

Riveting Roll Bar Structure

The outboard and inboard roll bar straps have been riveted to the forward roll bar frame assembly.

Riveting Roll Bar Structure

All of the rivets used so far are AN426AD4-5 rivets.

Riveting Roll Bar Structure

As per step six, on page 37-04 of the builder's manual, the (C-01432) bushing doublers were clecoed onto the aft roll bar frame assembly to be riveted with AN470AD4-5 rivets.

Four rivets will be installed per side.

Riveting Roll Bar Structure

I clamped the aft roll bar frame assembly to the edge of the bench to make it easier to rivet the bushing doublers to it.

Riveting Roll Bar Structure

It's just easier for me to see both sides of the rivet when the piece is upright.

Riveting Roll Bar Structure

A bronze oilite (BUSHBZ.502x.377x.375) bushing is next inserted into the center hole of the (F-01432) bushing doubler.

*Take note that in the plans the bushing is listed as (BUSHFBZ.502x.377x.375) but in the parts list it is listed as (BUSHBZ.502x.377x.375).

Riveting Roll Bar Structure

The (F-01433) bushing cover is then clecoed over top of the bushing and then riveted into place with four AN470AD4-6 rivets which I set with our pneumatic rivet squeezer.

Riveting Roll Bar Structure

As per step seven, on page 37-04 of the builder's manual, the aft roll bar frame assembly was set onto the forward roll bar frame assembly and the two halves, as well as the the two (F-01431D) window shims, were clecoed together.

Riveting Roll Bar Structure

Here's another view.

I am going to rivet these two roll bar frame assemblies together at the airport with the roll bar clecoed into position on the airframe.


Riveting Roll Bar Structure

As per step two, on page 37-05 of the builder's manual, the roll bar assembly was slid over the (F-01231D) roll bar bases and clecoed into position.

Riveting Roll Bar Structure

There are alot of clecos here so it helps to have two put the roll bar in place.

Riveting Roll Bar Structure

As per step three, on page 37-05, the (F-01432A) roll bar brace was clecoed into position to the (F-01406C) bulkhead.

Riveting Roll Bar Structure

The (F-01432A) roll bar brace was also clecoed into position on the top of the roll bar assembly to establish final alignment as per figure one, on page 37-05 and also referencing page 37-07 of the builder's manual.

Riveting Roll Bar Structure

I used our G-27 CherryMax hand rivet gun to set the CS4-4 and LP4-3 blind rivets.

Riveting Roll Bar Structure

With everything in alignment, the two roll bar frame assembly halves were riveted together using CS4-4 and LP4-3 rivets where indicated in figure one, on page 37-04 of the builder's manual.

Just as before, my riveting "plan of attack" was to alternately rivet from outer to inner and from left to right of center radiating outwards towards the bottoms of the roll bar frame assembly.

Riveting Roll Bar Structure

Nice!

Riveting Roll Bar Structure

Here's a view from underneath, these are all LP4-3 rivets on the aft roll bar frame assembly side.

Match Drilling Attachment Holes Into Roll Bar Base

Since everything is clecoed into position, might as well move on to step four, on page 37-05 of the builder's manual, where #30 holes are match drilled into the (F-01231D) roll bar bases as indicated in figure three.

The outboard six holes of the roll bar frame assembly are used as guides to #30 match drill holes into the outboard (F-01231D) roll bar base.

Match Drilling Attachment Holes Into Roll Bar Base

The inboard six holes of the roll bar frame assembly are used as guides to #30 match drill holes into the inboard (F-01231D) roll bar base.

*You really will need a 12" #30 drill bit to drill these inner #30 holes.
The longer bit allows the chuck of the drill to avoid hitting the (F-01405F) mid fuselage brace, especially when drilling the lower two holes.

Match Drilling Attachment Holes Into Roll Bar Base

As per step one, on page 37-06 of the builder's manual, the (C-01432) bushing doublers were clecoed into position on the forward roll bar frame assembly as shown in figure one.

The top two middle holes need to be #30 match drilled into the (F-01231D) roll bar bases.

After I #30 match drilled the (C-01432) bushing doublers, I labeled them so that they could be reassembled in the original position when it comes time to permanently install the roll bar assembly.

Fluting Skin Stiffeners

As per step three, on page 37-08 of the builder's manual, the (F-14125) skin stiffeners flanges were fluted as required per figure one to achieve good hole alignment.

*The skin stiffener with the hole in the top flange is the (F-14125-L) skin stiffener.

All parts were disassembled and the new #30 match drilled holes in the (F-01231D) roll bar bases were deburred.


Countersink Hole On Roll Bar Assembly

As per step four, on page 37-06 of the builder's manual, the center hole, on each front side of the roll bar assembly base, was machine countersunk to accept a CS4-4 rivet.

*Figure one on page 37-06 shows the location of which hole the plans want you to countersink.

Countersink Hole On Roll Bar Assembly

The hole is countersunk so that when the (C-01432) bushing doublers are riveted in place to the (C-01431D) roll bar bases, they will be able to lay flat against the roll bar assembly.

Location Of CS4-4 Rivet At Roll Bar Base

This is where the CS4-4 rivet will go when you get to step seven on page 37-06.

Countersink Hole On Roll Bar Assembly

Both bases of the roll bar assembly have a center hole that needs to be countersunk.

Paint Stand For Roll Bar Assembly

I want to paint the roll bar frame assembly and the roll bar brace before I install them into the airplane so I needed to build some sort of stand to sit the roll bar frame assembly on while it is being painted.
This is what I came up with; it has a dowel rod in the center so that I can rotate it while I paint.

Paint Stand For Roll Bar Assembly

Here is what it looks like when the roll bar frame assembly is placed into position for painting.


Preparing Roll Bar Assemblies For Priming

I scuffed all of the surfaces of the roll bar frame assembly with red ScotchBrite pads and washed everything down with acetone in preparation for priming.

Preparing Roll Bar Assemblies For Priming

I also scuffed the surfaces of the (F-01432A) roll bar brace with red ScotchBrite pads and washed everything down with acetone to prepare it for priming.

I made a separate stand out of PVC pipes to hang the (F-01432A) roll bar brace from while painting it as well, I'll show a picture of it later on in the blog; it uses a portion of the roll bar frame assembly paint stand to operate it.


Priming Roll Bar Brace

I primed the (F-01432A) roll bar brace with DupliColor DAP1690 self etching green primer.

If you want to see the PVC stand that I used to hold the roll bar brace while I painted it, click here to see what it looks like.

Primed Roll Bar Frame Assembly

I primed the roll bar frame assembly with DupliColor DAP1690 self etching green primer.

Primed Power Module Parts

The (F-14188B-L and F-14188B-R) power module brackets, (F-14188A) sub panel power module mount, and the (F-14125-L and F-14125-R) skin stiffeners were also primed with DupliColor DAP1690 self etching green primer.

Polished Bushing Covers

I wanted to have a little "bling" at the base of the roll bar frame assembly so I polished the (C-01433) bushing covers.


Primed Bushing Doublers

The (C-01432) bushing doublers were primed with DupliColor self etching green primer and then marked with a sharpie.

*Make sure to identify these bushing covers so that the orientation can be maintained, remember these were match drilled in step two, on page 37-06 of the builder's manual, you don't want to mix them up!

Roll Bar Brace Readied For Topcoat Paint

I prepared the (F-01432A) roll bar brace for topcoat painting by lightly scuffing the surfaces with a gray ScotchBrite pad and tacking the dust off with a Gerson tack cloth which is approved safe for waterbourne paints.

Roll Bar Frame Readied For Topcoat

The roll bar frame assembly was prepared for topcoat painting by lightly scuffing the surfaces with gray ScotchBrite pads.

*I did paint these parts with Stewart Systems Royal Blue EkoCrylic paint but I didn't like how they turned out so I am going to repaint them.


Topcoated Power Module Parts

After preparing the surfaces of the power module parts (F-14188B-L and F-14188B-R) brackets, (F-14188A) sub panel mount, and the (F-14125) skin stiffeners with ScotchBrite pads and tacking them off, I topcoated them with Stewart Systems Smoke Gray E5301 EkoCrylic paint.


Attaching Rudder Cable Sleeves

Each (CS-00014) rudder cable has a polyethylene sleeve pre-installed on them and the rudder cables need to be installed on each side of the (F-01451-L and F-01451-R) center tunnel sides with four MS21919DG6 adel clamps....sounds easy right? Wrong!!

This is the hole where the forward adel clamp attaches the (CS00014) rudder cable to the center tunnel side, the space is extremely tight and it is hard to place the NAS1149F0363P washer and the MS21042-3 locking nut onto the AN3-3A bolt as depicted in the detailed expanded view of figure one, on page 33-11 of the builder's manual.

You are going to have to use the "braille" method on these forward clamps, the aft ones aren't too bad because there is more room to get your hand in and you can also see what you are doing.

Attaching Washer With A Tool

This is how I slid the washer over the AN3-3A bolt, pretty simple, just a loop of electrical tape on the end of a popcycle stick.

Be patient, it may take a few trys to get it on the bolt!

*Be sure to have a magnet when doing this because when the washer or nut drops off of the bolt it's tough to get your hand down to the bottom of the space to retrieve the parts!

Attaching A Lock Nut In A Tight Place

As you know I tried to use an improvised tool to get this MS21042-3 locking nut onto the AN3-3A bolt. That idea didn't work but this is how I finally got the lock nuts installed.

It's pretty simple, just a double sided piece of carpet tape wrapped around your finger so that you can blindly reach into where the end of the bolt is.
The hard part is that on the inside of the side tunnel you have to apply a lot of pressure on the head of the AN3-3A bolt while simultaneously clockwise twisting the bolt to get the lock nut to thread on from the outside.

*If you landed here from where I first talked about a tool to possibly help install these locking nuts, click here to return to where you were.

Rudder Polyethylene Sleeve Attach Points

Finally! The polyethelene cables on the (CS-00014) rudder cables have been installed on each side of the (F-01451-L and F-01451-R) center tunnel sides as per step four and five, on page 33-11 of the builder's manual.

This is what the forward attachment looks like from the outside of the tunnel.

Rudder Cable Sleeves Attached To Center Tunnel

This is a view of the two attach points for the rudder cables to the center tunnel sides.

View Of Rudder Cable Sleeves On Left Outside Of Tunnel

This is what the attachment looks like on the inside of the center tunnel.

This is the inside view of the left center tunnel side.

Rudder Cable Sleeves View On Inner Tunnel

This is the view of the right center tunnel side.

Attaching Rudder Cable Brackets

As per step four, on page 33-12 of the builder's manual, the (CS-00014) rudder cables were attached to the (CS-00015) cable links using the hardware specified in figure two.

This is the left cockpit side.

As per step five, on page 33-12 of the builder's manual, the (CS-00015) cable links were attached to the (WD-655-L and WD-655-R) rudder pedals using the hardware specified in figure two.

*The nuts and bolts were only tightened "finger tight" as no standard torque value is to be used here.

Attaching Rudder Cable Brackets

This is the right cockpit side.

Attaching Rudder Cable Guides

As per step eight, on page 33-12 of the builder's manual, the (F-01497A and F-01497B) cable guides were clecoed into position to the (F-01451-L and F-01451-R) center tunnel sides so that they can be riveted into place using the hardware specified in figure two.

This is the right cockpit side.

Attaching Rudder Cable Guides

This is the left cockpit side.

Rudder Cable Guides Riveted In Place

Basically the (F-01497A and F-01497B) cable guides are some sort of nylon or teflon material which is riveted to the tunnel sides with AACQ4-3 and AACQ4-6 blind rivets backed up with NAS1149FN432P washers.

This is the left cockpit side looking towards the right side, you can see the "milky white" plastic rudder guide material I'm talking about on the inner side of the center tunnel.

Rudder Cable Guides Riveted In Place

This is the right cockpit side looking towards the left side.


Attaching Wiring Channel Assembly

As per step five, on page 35-10 of the builder's manual, the (F-14106) wiring channel assembly was clecoed to the (F-01455) instrument sub panel and the inboard sides of the (F-01451-L and F-01451-R) center tunnel sides.

The bottom two tabs of the wiring channel assembly were attached by using LP4-3 rivets.

Attaching Wiring Channel Assembly

Our forward fuselage is a quickbuild option from Van's Aircraft and the space at the top of where the (F-14106) wiring channel assembly attaches to the (F-01455) instrument sub panel was so tight that we were unable to rivet the wiring channel assembly with the AN470AD4-4 rivets called for in figure two, on page 35-10 of the builder's manual, so we used LP4-3 rivets as a substitute.

Attaching Grommet Strip With JB Weld

In step one, on page 59-03 of the builder's manual, a 12" grommet strip, (MS21266-N1), is to be secured around the bottom and sides of the (F-14106) wiring channel as indicated in figure one.

The strip won't stay in place without being glued in so I am using JB Weld Plastic Bonder as an adhesive to hold it in place.

Clamping Grommet Strip To Wiring Channel Assembly

I used sliced up bicycle inner tubing held in place with safety wire as clamps while the JB Weld cured.

Removed Clamps On Grommet Strip

Here is what the grommet looks like after the clamps have been removed and the JB Weld has fully cured, it worked pretty well!

Installing Flap Torque Arm Tubes

As per step four, on page 34-03 of the builder's manual, #5 Aeroshell wheel bearing grease was applied to the areas of the (CS-00010-L and CS-00010-R) flap torque arm tubes before they were slid through the (F-1030) outboard bushings and into the fuselage, under the (CS-00014) rudder cables, and into the (F-1030) inboard bushings until the ends of the torque tubes were flush with the inboard bushing's inboard face.

*Make sure to check that the torque tube sits under the rudder cables as shown in figure four, on page 34-03.

Installing Flap Torque Arm Tubes

The right (CS-00010-R) flap torque arm tube is installed the same as the left side.

Installing Flap Torque Arm Tubes

This is what the flap torque tube arm looks like when it is flush with the inboard face of the (F-1030) inboard bushing.

Sizing The Flap Crank

As per step one, on page 34-04 of the builder's manual, the (WD-1013A) flap crank joins the two (CS-00010) flap torque arm tubes in the center tunnel but I found that this flap torque arm needed to be trimmed in width because it would not fit into the center tunnel as it should.

As you can see it needed less than 1/16" trimmed off in order to fit into the center tunnel and be able to be joined with the two flap torque arm tubes.


Trimming The Flap Crank

Here is a better view of the (WD-1013A) flap crank.

Trimming The Flap Crank

I used our stationary disc sander to remove the excess material from each end of the (WD-1013A) flap crank.

Resized Flap Crank

Here is the (WD-1013A) flap crank after the excess material has been trimmed off.


Flap Crank Installation

As per step one, on page 34-04 of the builder's manual, the (WD-1013A) flap crank was inserted into the center tunnel in line with the axis of the (CS-00010-L and CS-00010-R) flap torque arm tubes as shown in figure one.

*At this point the plans don't mention very much about how the ends of the (CS-00010-L and CS00010-R) flap torque arm tubes and the (WD-1013A) flap crank should be "clocked" relative to each other so be sure to reference the illustrations on page 34-01 and on 34-04 to get the geometry right....you can get it backwards!

Flap Crank Installation

Here is another view, the (WD-1013A) flap crank should be standing up and slightly forward.

Flap System Clocking

Check the position of the end of the (CS-00010-R) flap torque arm tube. It should be facing forward.

Once the geometry looks right then attach the parts together with the hardware called out in figure one, on page 34-04.

Flap System Clocking

This is the left fuselage side. The (WD-1013A) flap crank is standing up and slightly forward and the end of the (CS-00010-L) flap torque arm tube is facing forward.

Flap Crank Connections

The bolts called for to join the flap torque tube assembly together are AN3-14A secured with MS21042-3 lock nuts. The lock nuts were torque set at 42"/pounds, (28"/pound for AN3 bolt + 14"/pound for my torque wrench friction drag).

The lock nuts were then sealed with torque sealant.

Flap Crank Connections

There are four bolts securing the flap crank to the flap torque arm tubes, be sure to secure them all properly.

*After everything is connected and secured, don't forget to test the flap mechanism manually for freedom of movement, they must not bind. Ours worked freely and smoothly!

Air Vent Install

As per step six, on page 29-22 of the builder's manual, it's time to attach the fresh air vents.

A thin bead of (MC-236-B1/2) tank sealant was applied to the outboard faces of the (SV-10-L and SV-10-R) NACA fresh air vents and (F-14186-L and F-14186-R) NACA vent brackets and as per step seven the units placed into position and clamped using neodynmium magnets to hold them in position while the tank sealant cured.

A fellow RV14 builder told me about the magnet trick....it really works great!

Air Vent Install

Here is what it looks like from the inside.

I used eight magnets per side so make sure you get enough magnets if you are going to use this clamping method.

Air Vent Install

Here's a better view of the other side.

Air Vent Install

Again, four magnets on the outside and four on the inside. Don't worry, the magnets are really strong and they hold the assembly well, even through the aluminum skins!


Air Vent Installed

After the tank sealant fully cured for a few days I removed the magnets.

This is the right fuselage side.

Air Vent Installed

This is the left fuselage side.

I elected to install the optional Flap Position Sensor onto our airplane. It is kit part number 14 Flap Position Kit.

As per step one, on page 54-04 of the builder's manual, a 1/4" piece was cut from the 1 1/4" (PT-PU-.066x.125) flexible plastic tubing.

Flap Position Sensor Install

This 1/4" of tubing will act as a bushing when inserted into a #30 hole drilled into the (WD-1013A) flap crank.

Flap Position Sensor Install

The 1/4" tubing was inserted into position on the (WD-1013A) flap crank.
It is a bushing for the (F-14127) flap position pushrod.

Flap Position Sensor Install

As per step two, on page 54-04 of the builder's manual, the (F-14127) flap position pushrod was inserted through the plastic tubing as seen in figure one.

The (F-14127) flap position pushrod is also connected to the (ES MSTS POS-12) position sensor arm.

Flap Motor Install

As per step five, on page 54-04, and step four, on page 34-04 of the builder's manual, the hardware seen on this page was used to connect the (ES 85615-10) linear actuator lug to the (F-01466L and F-01466R) flap motor brackets.

*The AN4-12 bolt was lightly greased with #5 Aeroshell wheel bearing grease before installation.

It is important not to overtighten the bolt and nut because this is supposed to be a freely moving joint.

Flap Motor Install

Here is what it looks like installed.

Painting Roll Bar Brace

I stated earlier that I wasn't happy with the way the (F-01432A) roll bar brace turned out so here I am painting it again with Stewart Systems E5465 royal blue EkoCrylic topcoat paint.
I am using the PVC stand I made to hold the part while I paint.

*If you landed here from where I first talked about a PVC stand to prime the roll bar brace with, click here to return to where you were.

Painted Roll Bar Brace

The (F-01432A) roll bar brace turned out a lot better this time.

*I must admit that the Stewart System paint is tricky to use and very "finicky", I may be rethinking my decision to paint the rest of the airplane with it.


Safety Wire Pliers

These are the reversible safety wire pliers/twisters that I use, I will be using them later after I connect the flap actuator motor to the flap crank.

Attaching Flap Motor To Flap Crank

As per step four, on page 54-04 of the builder's manual, the (ES 85615-10) flap linear actuator was run to full extension and then the rod end bearing was bolted to the (WD-1013A) flap crank using the hardware specified in figure one, on page 34-05.

A fellow RVer told me how to use my cordless drill battery to extend the flap motor to the full extension, it worked great! Just reverse the wires on the flap motor when you want to reverse the direction of travel.

Attaching Flap Motor To Flap Crank

As per step two, on page 34-05 of the builder's manual, .032 safety wire was routed through the pre-drilled hole on the (ES 85615-10) linear actuator shaft, around the (AL.259x.375x.168) bushings and back to the actuator shaft, twisted and secured into place with the safety wire pliers.

Attaching Flap Sensor And Securing

Here's another view.

Attached Flap Sensor And Securing

As per step six, on page 54-04 of the builder's manual, the (ES MSTS POS-12) position arm was fully extended by hand and per step seven, the (F-14127) flap position pushrod was attached to it.

As per step eight, the (ES MSTS POS-12) flap position sensor, which was bolted to the (F-01405G) flap motor channel, was fully secured using the hardware called for in figure two on page 54-04.

Trimming Idler Bracket To Fit Idler Arms

These (CS-00011) idler arms need to be installed to the (F-01405E) idler brackets.

In step two, on page 36-02 of the builder's manual, the clearance of the idler arms are to be checked to see if they clear the idler brackets freely. They didn't so the flanges on the (F-01405E) idler brackets need to be trimmed so that the idler arms don't rub against them.

Trimming Idler Bracket

These are the (F-01405E) idler brackets that need to be trimmed.

The arrows point to the flanges (on both sides) that need to be trimmed.


Painting Roll Bar Frame

Today I set up an area so that I can repaint the roll bar frame assembly.
You can see the stand I made to place the roll bar frame on when I am painting. I am using a single 5 hp compressor to paint this part but I also have a dual compressor setup for when I paint the bigger parts.

This is a temporary setup, I have a paint booth that I will use later to paint the rest of the airplane.

Painting Roll Bar Frame

Just another view.

Attached Idler Arms To Idler Bracket

Back again to the (F-01405E) idler brackets that need to be trimmed...

I used a flat file and also sandpaper to achieve the clearance needed and then as per step two, on page 36-02 of the builder's manual, I bolted the (CS-00011) idler arms to the (F-01405E) idler brackets using the hardware called out in figure two.

*The manual requires at least .003" gap for clearance.

Attached Idler Arms To Idler Bracket

Here's another view.

Painted Roll Bar Frame Assembly

I repainted the roll bar frame assembly with Stewart Systems E5465 royal blue EkoCrylic topcoat paint.


Roll Bar Frame Assembly

I finished painting the roll bar frame assembly and polished it.


Forward Elevator Pushrod

As per step one, on page 36-05 of the builder's manual, the (CS-00001) forward elevator pushrod was installed by feeding it through the (F-01406B) bulkhead.

You have to feed it through the hole at the bottom of the (F-01406B) bulkhead starting aft of the bulkhead and then slide it forward towards the front of the fuselage, through the center section bulkhead assemblies, where you can then connect it to the (CS-00006) control column as seen in figure two on page 36-05.

You have to insert it this way because the slope of the floor in the fuselage and the length of the pushrod won't let you do it any other way.

Forward Elevator Pushrod Bolts

As per step two, on page 36-05, the (CS-00001) forward elevator pushrod was bolted to the (CS-00006) control column using the hardware called out in figure two.

This is an AN3-10A bolt, two NAS1149F0363P washers, and a MS21042-3 lock nut.

Torque Set Forward Elevator Pushrod Bolts

The MS21042-3 lock nut, shown by the red arrow, was then torqued to a value of 42 inch/pounds (28"/lbs for the nut + 14"/lbs wrench drag friction = 42"/lbs.)

I put yellow torque seal on the nut so that it can be checked later when inspection time comes.

Forward Elevator Pushrod Routing

Here is what the (CS-00001) forward elevator pushrod looks like from above as it runs aft towards where it will be connected to the (CS-00011) idler arms.

Bellcrank Mount Mock-up

If you ever want to install an auto pilot yaw servo (Section 58), now is a good time to do it.

*(Actually the best time to do it is when you are putting the tailcone together and before you add the skins, but who knew??)

The (CS-00002) mid elevator pushrod assembly and the bellcrank assembly are going to be installed shortly but before I do that I mocked up and set into the proper position, the (F-14139) bellcrank mount, (F-14184) auto pilot pitch servo bracket, the (F-14189A) auto pilot yaw servo plate, and the (F-14189B) yaw servo support onto the (F-1037B and F-1037C) battery angles so that four #30 holes in the (F-14189B) yaw servo support can be match drilled into the (F-01407-L and F-01407-R) side frames.


Match Drill Yaw Servo Support Attach Holes

As per step ten, on page 58-02 of the builder's manual, the four #30 holes of the (F-14189B) yaw servo support were match drilled into the (F-01407-L and F-01407-R) side frames and the (F-01429L and F-01429r) bellcrank ribs using an angled drill attachment and my cordless drill.

*The drill attachment is a 12" DeWalt DWARAFS that requires 1/4" hex bits. It is flexible and can really get into tight spaces!


Mid Elevator Pushrod And Bellcrank Mount Bolted Into Place

As per step two, on page 36-07 of the builder's manual, the (CS-00002) mid elevator pushrod assembly was bolted to the bellcrank assembly using the hardware called out in figure two.

The AN316-4R jam nut on the (CS-00002) mid elevator pushrod assembly was torqued to 20 inch/pounds and torque seal was applied.

The MS21042-3 lock nut on the connection to the bellcrank assembly was torqued to 42 inch/pounds (28"/lbs + 14"/lbs wrench drag = 42"/lbs) and then torque sealed.

Figure one, on page 36-08 show the hardware to be used to install the bellcrank assembly to the battery angles but be sure to take note of the four screw substitutions (AN525-832R9) called for on page 58-02, figure two, when assembling everything into final place.

Mid Elevator Pushrod Attached To Bellcrank Assembly

The red arrow shows the mid elevator assembly, bellcrank assembly connection as viewed from the front looking aft through the battery angles.

Torque Sealed Harware Of The Mid Elevator Pushrod

This is a view of the mid elevator assembly, bellcrank assembly connection from the side.

Riveting Yaw Servo Support To Fuselage Side Frames

As per step thirteen, on page 58-02 of the builder's manual, the (F-14189B) yaw servo support was riveted to the (F-01407-L and F-01407-R) side frames and the (F-01429-L and F-01429-R) bellcrank ribs with AN470AD4-5 rivets.

*The two top rivets were set with our pnuematic squeezer but the bottom two rivets had to be set with our 3x rivet gun with an angled cupped rivet set and a small tungsten bucking bar because of the tight spaces and the slope of the bottom skin.


Torque Set Jam Nut On Servo Pushrod Assembly

As per step two, on page 56-02 of the builder's manual, the jam nuts (AN316-4R) of the (CS-00017) pitch servo pushrod assembly were final torqued to 20 inch/pounds and torque sealed.

As per step three, on page 56-02 of the builder's manual, the jam nuts (AN316-4R) on the (CS-00019) roll servo pushrod assembly were final torqued to 20 inch/pounds and torque sealed.

Torque Set Jam Nut On Servo Pushrod Assembly

Torque Set Tool

Jonard Tools makes precision, pre-set, torque wrenches to set torques of 20 inch/pounds, this is what I used to torque set the jam nuts on these pushrods.


Autopilot Pitch Servo Install

As per step two, on page 56-03 of the builder's manual, the servo arm of the Garmin GSA 28 autopilot pitch servo needs to be removed.
This is so that it can be attached to the (F-14184) pitch servo bracket.

Autopilot Pitch Servo Arm Removed

As you can see in this photograph, the (MS24665-208) cotter pin will need to replaced but there is an extra one in bag 3342 of the hardware inventory.

Autopilot Pitch Servo Install

This is kind of cramped back here and the (F-14184) pitch servo bracket is located just forward of the (F-01407) bulkhead assembly.

Autopilot Pitch Servo install

As per step three, on page 56-03, and referencing figure one, the Garmin GSA 28 autopilot pitch servo was attached to the (F-14184) pitch servo bracket using the hardware as called for in figure one.

*Make sure that the Garmin GSA 28 servo arm is positioned pointing upwards as indicated in figure one.

Don't forget to leave the upper aft attach hole empty for now because there will be an electric ring terminal attached here later.

The (MS21042-3) nuts are torqued to 28 inch/pounds and torque sealed.

When you reinstall the Garmin GSA 28 servo arm, make sure to use a new (MS24665-208) cotter pin and do not torque the castle nut with more than 20 inch/pounds.

CS-00017 Pitch Servo Pushrod

As per step three, on page 56-04 of the builder's manual, the (CS-00017) pitch servo pushrod assembly was attached to the Garmin GSA 28 autopilot pitch servo and the elevator bellcrank assembly as shown in figure one.

The (MS21042-0) nuts were torqued to 28 inch/pounds and later torque sealed.

*The (AN316-4R) jamb nuts on the pushrod were torqued to 20 inch/pounds and torque sealed.

As per step seven and figure one, on page 56-04, the ring terminal was attached to the upper aft hole of the pitch servo and the (F-14184) pitch servo servo bracket making sure that the ring terminal was between the washer and the servo flange.

*The connecting (MS21042-3) nut was torqued to 28 inch/pounds and torque sealed.

CS-00003 Aft Elevator Pushrod

As per step four, on page 36-15 of the builder's manual, the (CS-00003) aft elevator pushrod was fed forward through the opening in the (F-01411) bulkhead and per step six, on page 36-15, attached to the bellcrank assembly using the hardware called for in figure four.

*The (MS21042-3) nut was torqued to 28 inch/pounds and torque sealed.


Molex Connector

The Garmin GSA 28 autopilot pitch and yaw servo has a 12 pin molex connector at the end of the (WH-00118) wiring harness; it needs to be labeled.

This is what the forward end looks like. It is attached to the (F-01406B) bulkhead.

Labeled 12 Pin Molex Connector

As per step four, on page 56-04 of the builder's manual, the 12 pin molex connector on the (WH-00118) Garmin pitch and yaw servo harness was labeled "C411J" with a sharpie.

12 Pin Molex Connector

This is what the aft end of the Garmin GSA 28 autopilot pitch and yaw servo 12 pin molex connector on the (WH-00118) harness looks like.

Routing Autopilot Wiring Harness In Fuselage

As per step five, on page 56-04 of the builder's manual, the 15 pin female d-sub connector labeled "PITCH" was attached to the Garmin GSA 28 autopilot pitch servo.

As per step six, on page 56-04 of the builder's manual, the (WH-00118 and C411J) wiring harness and connector were routed forward along the right side of the (F-01429-R) bellcrank rib and tie wrapped into place and also back onto itself as shown in figure one.

The 15 pin d-sub connector labeled "YAW" was tie wrapped onto the (F-14184) pitch servo bracket.

C411J Installed To F-01406B Bulkhead

This shows "C411J" installed in it's position on the (F-01406B) bulkhead.

*The plans are a bit confusing at this point because they talk about a connector called "C411P" and a wiring harness called (WH-00125) A call to Van's Aircraft confirmed that these DO NOT EXIST!

These either have to be custom built by the owner or an avionics shop, so save yourself the trouble of trying to find them....


Steps one and two, on page 56-04 talk about two wires labeled (C1036 and C1037), they are still here (you can see them in this photograph below the molex connector) and will eventually pass through the grommet in (F-01406B) bulkhead and make a 180° back into the custom made mid fuselage wiring harness and connector (WH-00125/ C411P).

Connecting Control Stick Bases

As per step three, on page 36-11 of the builder's manual, the (CS-00007-L and CS-00007-R) control stick bases were bolted to the (CS-00006) control column ends using the hardware called out in figure two.

The (MS21042-4) nuts were torqued to 28 inch/pounds and torque sealed.

Connecting Control Stick Bases

Here is another view from the right fuselage side.

*I left the (CS-00008-L and CS00008-R) control sticks still loosely attached because there will be an alignment check coming up on page 36-14.

Connecting Stick Link Pushrod

As per step one, on page 36-12 of the builder's manual, the (CS-00004) stick link pushrod was attached to the (CS-00007-L and CS-00007-R) control stick bases using the hardware called out in figure one.

*It was a little tricky to get the (5702-75-60) washers into position but I found if I used the "washer and double sided tape on a popsicle stick tool" it worked out just fine.

Connecting Stick Link Pushrod

This photograph shows the green (CS-00004) stick link pushrod running in parallel with the (CS-00006) control column after installation.

Control Stick Alignment

Time to check the alignment of the (CS-00007-L and CS-00007-R) control stick bases as described on page 36-14, step two.

The alignment was checked by measuring the inside distances between the tops and bottoms of the (CS-00008-L and CS-00008-R) control sticks to see if they are parallel.

Our sticks measured at exactly 20 5/8" just as predicted in figure two on page 36-14.

The (MS21042-3) nuts were torqued to 28 inch/pounds and torque sealed after the alignment check was completed.

*The (AN316-4R) jamb nuts on the (CS-00004) stick link pushrod assembly were torqued to 20 inch/pounds and torque sealed as well.

Torque Sealed Stick Link Pushrod

Here is a view of the connection on the (CS-00004) stick link pushrod end.

Torque Sealed Stick Link Pushrod

Right side view.

Elevator Pushrod Connections

As per step one, on page 36-09 of the builder's manual, the (CS-00001) aft elevator pushrod assembly and the (CS-00002) aft elevator assembly were bolted to the (CS-00011) idler arm using the hardware called out in figure one.

The bottom two (MS21042-3) nuts were torqued to 28 inch/pounds.


Torque Seal CS-00001

Torque seal was applied to the AN316-4R jam nuts on the (CS-00001) forward elevator pushrod and the (CS-00002) mid elevator pushrod after they were torqued to 20 inch/pounds.

Torque seal was also applied to the MS21042-3 nuts that connect the (CS-00001) forward elevator pushrod and the (CS-00002) mid elevator pushrod to the (CS-00011) idler arms after they were torqued to 28 inch/pounds.

Finish Kit Arrival

Our finish kit has finally arrived!

It took a long time to finally get here, we ordered it last June and it took almost 11 months to be recieved by us....there are still some items that are on back order, we'll have to see what they are once we get the crate opened up and do the inventory.

We have 30 days to finish the inventory and report any discrepencies to Van's Aircraft.

Finish Kit Box

We ordered the portable lift so that unloading the crate wouldn't be a problem.

Finish Kit Box

We placed the crate on two mover "dollies" so that we can move the crate around the hangar if needed.

Finish Kit Box

Time to open the crate and do the parts inventory....


Inventory Finish Kit

There are quite a few staples and screws holding this crate together so it is going to take awhile to get this opened up.

Packed Finish Kit Crate

It is really something to see how much Van's Aircraft can get into one crate!

*Overall, it took us almost five hours to open the crate and do the inventory of the large parts.

Wheel Pants

First items to come out of the crate were the wheel pants.

Fairings

Some more fairings and starting to get to some of the parts that make up the tip up canopy, which still have to be unwrapped.

Finish Kit Small Parts

The tip up canopy parts are unwrapped, but still more to go...

Interior Cover Plates

The parts are piling up!

Tight Packing In Finish Kit

Look how tightly packed everything is. This is the front landing gear strut and the engine mount.

Landing Gear

These are the three landing gear struts.

Engine Mount

Finish Kit Small Parts

All of the small parts in the individual bags have to be inventoried.

Duplicate Parts

We got two (C-01415-R) right forward intercoastals and the left forward intercostal (C-01415-L) was missing so make sure the inventory is thorough!

*Van's Aircraft was quick to get the missing parts out to us so it went smoothly!

We managed to compress all of the paper so that it could be disposed of.


Hardware Inventory For Finish Kit

We took the large hardware bag home to do the final inventory of parts.

*It took over 5.5 hours to finish up the inventory of all the nuts and bolts and small pieces that were in this bag!

We did find a few things short on the inventory list and the brakes and wheels are still on backorder....


Finish Kit Final Items

The final items that were on back order from the finish kit arrived!

Let's open up the box and see what's inside...

*It took one year and three months from when we first ordered the finish kit for these final items to arrive....

Finish Kit Final Items

The back ordered items were: (Bag 3215-1) which includes all of the nose gear hardware, (F-00017-L and F-00017-R) steps for the RV14A, and (U-55-204) Grove 5.0 x 5 RV-14A wheels and wheel brakes.

Finish Kit Final Items

These are the items in (Bag 3215-1) nose gear hardware.

*It took 1 hour 5 minutes to do the inventory....had to get an 1.5" axle nut sent that was missing.


Calibrate Elevator Pitch Range

As per steps one and two, on page 36-13, of the builder's manual, the travel of the (CS-00006) control column needs to be checked with a digital level.

I checked the travel on a previous occassion but I wanted to check it again after talking with Van's Aircraft to see if I was interpreting my findings correctly.
We both came to the conclusion that the forward travel needs to be corrected....mine is not going foward enough.

The first step is to place a digital level on the top flange of the (F-01438) cover rib and zero the level.

Inkuen Digital Angle Level

This is the digital level that I am using, I got it on Amazon $22.99.

The Control Column travel limits are depicted in figure one, on page 36-13 of the builder's manual.
They are: Forward travel- 13.6° (+3.0°/-0.0°) Aft travel- 23.1° (+3.0°/-0.0°).

Bearing bracket Assembly

There are two Bearing Bracket Assemblies (F-01450-L and F-01450-R) that the (CS-00006) Control Column contacts that set the travel limits.....the arrow is pointing at the Left Bearing Bracket Assembly in this photograph.
This is the portion of the Bearing Bracket Assembly that determines the aft travel limit. The bottom of this bracket (hidden from view here) sets the forward travel limit.

*If you want to see more references to the Bearing Bracket Assemblies go to the builder's manual pages 25-03, 25-04, 25-05, and 29-05.

Left Foward Stop 12.65°

Here is where the forward limit on my control is now. (It needs to be able to go forward another 0.95° in order to reach the minimum 13.6°.)

Left Aft Stop 24.40°

This shows the aft limit. (It is within limits.)

Zero Out Digital Angle Gauge

Now to measure the travel limits on the right side Control Column...
First, zero out the digital level.

Right Forward Stop 12.40°

Here is where the right side forward limit on my control is now. (It needs be able to go forward another 1.2° in order to reach the 13.60° limit.)

Right Aft Stop 25.20°

Here is where the right side aft limit is. (It is within limits.)

*There is another important piece of information to note here: the forward and aft limits of both sides of the Control Column should be the same and contact the stops simultaneously....how do you fix that?

First, according to Van's Aircraft, these are basically secondary stops and while they need to be as close as possible to one another you don't need to "freak out" if they aren't exactly the same because the more critical stops will be set in the tail section.

If the stops do not contact simultaneously or if more deflection is required, you need to find out which stop needs to be adjusted. By using a piece of paper as a feeler gauge inserted between the stop and the control column (figure two, section A-A, on page 36-13 shows you how to position the paper slip) you should be able to determine which stop is limiting the travel.
I found that my left side, forward stop, needed to be filed down slightly.

Unfortunately the space is very limited to gain access to the stop so I need a smaller file and it is at home....I guess this will be a job to do later!


Bushing AL .377x.75x1.6875

On page 40A-03, figure three, of the builder's manual, there are two (BUSHING AL .377x.75x1.6875) aluminum bushings that rest between the center section assembly that I want to prime.

Bushing AL .377x.75x1.6875

These bushings are used with the AN6-43A bolts that attach the (U-01404-L and U-01404-R) Upper Gear Braces to the center section assembly.

Bushing Prepared For Priming

I primed the (BUSHING AL .377x.75x1.6875) aluminum bushings with Tempo A-702 Valspar primer green zinc phosphate primer.

Bushing AL .377x.75x1.6875 Primed

I used the Tempo A-702 Valspar primer green zinc phosphate primer on these today because it is able to be used in temperatures as low as 50°F and the shop isn't heated....I kept them inside the house to dry properly though!

Trim Corners Of Seatback Angles

These are the two pairs of (F-1237C-L and F-1237C-R) seatback angles. They need to be modified.

Trim Corners Of Seatback Angles

As per step one, on page 39-02, of the builder's manual, and referencing figure one, lay out lines were placed on the (F-1237C-L and F-1237C-R) seatback angles.

This excess material needs to be removed.

Trim Lines Drawn On Seatback Angles

Only one end of each seatback angle needs to have excess material removed, the reference notches that were used to lay out the cut out lines help you figure which side to remove the material from; essentially there are going to be right and left side seatback angles for each seat.

Cutting Seatback Angles

I cut off the excess material from the (F-1237C-L and F-1237C-R) seatback angles using a bandsaw.

Separate F-1237BD Seatback Angle

These are the (F-1237BD) seatback angles that need to be separated.

Trim Line For F-1237BD Seatback Angle

This is a closer view of where the gap is and the cut is to be made.

Separated F-1237BD Seatback Angle

As per step two, on page 39-02, figure two, the (F-1237BD) seatback angles were separated making them (F-1237B) upper and (F-1237D) lower seatback angles.

Separated Seatback Angles

Let the deburring begin!


Deburr Seatback Angles

I started deburring the (F-1237C-L and F-1237C-R) seatback angles first.


Deburr Seatback Angles

Two done....


Deburr Seatback Angles


Deburred Seatback Angles

Four done!


Deburring Upper And Lower Seatback Angles

The deburring of the edges of the (F-1237B) upper and (F-1237D) lower seatback angles begins. These seatback angles are not equal in length.

Upper And Lower Seatback Angles

The (F-1237B) upper seatback angle is 14 15/16" long and the (F-1237D) lower seatback angle is 12" long.


Deburred Upper And Lower Seatback Angles

All of the edges of the upper and lower seatback angles have been deburred.

Separating Seatback Braces

These are the (F-01437) seatback braces.

Separating Seatback Braces

The (F-01437) seatback braces need to be separated.

Separating Seatback Braces

As per step three, on page 39-02, and referencing figure three, the (F-01437) seatback braces were separated using the bandsaw.

Separated Seatback Braces

The (F-01437) seatback braces are now separated, the edges are rough so definitely going to have to spend some time deburring these!

Separating Seatback Stiffeners

Since I already have the bandsaw out I decided to go ahead several steps and separate the four (F-01437A) seatback brace stiffeners.

Separating Seatback Stiffeners

Separated Seatback Stiffeners

As step nine, on page 39-03, figure three, I separated the (F-01437A) seatback brace stiffeners using the bandsaw.

F-1237H Seatback Hinge

These (AN257-P3) hinges need to be modified but first make sure you have the right hinge because there is another different sized hinge that you will be using later and you don't want to mix them up.

I removed the hinge pin and labeled it and these too.

Locating Holes And Eyelet Removal On Seatback Hinge

As per steps five and six, on page 39-02, and referencing figure four, two (F-1237H) seatback hinges were fabricated from one half of a (AN257-P3) hinge.

The center eyelet was removed and #30 locating holes were drilled 1/4" from the edges of one end of the hinge. All of the edges and holes were deburred as well.


Separated Seatback Brace

Time to start deburring the (F-01437) seatback braces.

Deburring Seatback Brace

The edges of the (F-01437) seatback braces are easy enough to do but the real "fun" part is deburring the lightening holes...

Deburring Seatback Brace

Edges deburred!


Deburred Seatback Brace Edge

Just want to have these edges on the (F-01437) seatback braces nice and smooth, don't want them to snag anything since they will be at the back of the seat!


12 Inch Seatback Hinge

The (F-1237H) seatback hinge needs to have #30 holes from the (F-1237D) lower seatback angle match drilled into it.

Match Drilling 12 Inch Seatback Hinge

Before clecoing the (F-1237H) seatback hinge to the (F-1237D) lower seatback angle, I laid out a guide line along the center of the hinge so that it could be visually seen when "flipped over" and I also drew center lines along the holes of the (F-1237D) lower seatback angle so that the two lines, when clamped together, would be aligned with one another thereby insuring that the hinge remained parallel to the edges of the seatback angle while the match drilling progressed.

Match Drilling 12 Inch Seatback Hinge

If you look closely, you can see the guide lines on the hinge showing through the centers of the holes on the lower seatback angle.

Match Drilling 12 Inch Seatback Hinge

As per step two, on page 39-03, figure one, I match drilled #30 holes of the (F-1237D) lower seatback angle into the (F-1237H) seatback hinge, clecoing each as the drilling progressed.

Match Drilled 12 Inch Seatback Hinge

Nine #30 holes match drilled into the (F-1237H) seatback hinge.

Marked 12 Inch Seatback Hinge

As per step three, on page 39-03, marked the (F-1237H) seatback hinge and the (F-1237D) lower seatback angle so that they could be disassembled, deburred, and then reassembled in their original configuration.

Match Drilling 12 Inch Seatback Hinge

Time to repeat steps one three for the second (F-1237H) seatback angle and (F-1237D) lower seatback angle assembly.

Both 12 Inch Seatback Hinges Match Drilled

I disassembled all of the parts, deburred them and then reassembled them for later use.

AN257-P2 Hinge

This is that second hinge that I was talking about earlier, a (AN257-P2) hinge.

AN257-P2 Hinge

This (AN257-P2) hinge is not as wide as the (AN257-P3) hinge.

Removed And Labeled Hinge Pin

I removed the hinge pin and labeled it.....don't want to get it confused with the other hinge pin!

Fabricate F-1237F Seatback Brace Hinge

As per step five, on page 39-03, and figure 2, two pairs of (F-1237F) seatback brace hinges need to be fabricated using the (AN257-P2) hinge.

These hinges are too long to cut on my bandsaw so I had to cut them the "old fashioned way" with a hacksaw.

F-1237F Seatback Brace Hinges

One half of the hinge pair is 13 1/2" long and the mating half is 12 1/2" long.

Locating Hole Drilled For F-1237F Seatback Brace Hinge

As per step six, on page 39-03, I drilled #30 locating holes in each half of the (F-1237F) seatback brace hinges (1/4" from each edge) as per figure two.

Lay Out Guide Lines On F-1237F Seatback Brace Hinges

As per step seven, on page 39-03, figure two, I drew 1/4" reference lines lengthwise on the 12 1/2" (F-1237F) seatback brace hinge.

*Make sure to draw the line on the correct side of the hinge as indicated on the small illustration at the left side of the drawing.


Deburring F-01437A Brace Stiffeners

These four (F-01437A) brace stiffeners that were separated earlier are rough, they need to be deburred.

Deburring F-01437A Brace Stiffeners

Nice!


Machine Countersinking Brace Stiffeners

As per step eight, on page 39-03, these four (F-01437A) brace stiffeners need to be machine countersunk to accept the head of a AN426AD3-4 rivet.

Machine Countersinking Brace Stiffeners

Only one side of the (F-01437A) brace stiffeners will be countersunk.

Later, the rivets to attach these stiffeners to the seatback braces will be double flush riveted.

Match Drilling Seatback Hinge

As per step ten, on page 39-03, I clecoed the #30 locating hole in the 13 1/2" half of the (F-1237F) seatback brace hinge to the (F-01437) seatback brace.

Locating Guide Holes On Seatback Brace Hinge

#30 holes will be match drilled into the (F-1237F) seatback brace hinge using the pre-drilled holes of the (F-01437) seatback brace as guides.

*Here is a closer look at what I was describing earlier; you can see the reference line drawn on the hinge lined up with the center of the holes on the seatback brace so that alignment can be monitored while the match drilling process progresses.

Match Drilled Seatback Brace Hinge

Make sure that you have something to support the assembly while you match drill the holes.

Match Drilled Seatback Brace Hinge

Can't have enough clamps! Cleco the holes as you go....

Match Drilled Seatback Brace Hinge

As per step eleven, on page 39-03, all of the #30 holes of the (F-01437) seatback brace have been match drilled into the 13 1/2" half of the (F-1237F) seatback hinge.

Match Drilled Seatback Brace Hinge

Repeat steps ten, eleven, and 13 for the second seatback/hinge assembly.

Match Drilled Seatback Brace Hinge

Here you can see the marks drawn on each assembly so that they can be disassembled, deburred, and reassembled in their original configuration.

Marked Seatback Brace Assembly

Just a closer look at the marks I used.

Marked Seatback Brace Assembly

Marks as per step thirteen, on page 39-03.


Seatback Brace Assemblies

As per step twelve, on page 39-03, figure four, I clecoed the (F-01437A) brace stiffeners to the (F-01437) seatback braces and machine countersunk the (F-01437) seatback braces so that the head of a AN426AD3-4 rivet could be double flush riveted to hold the (F-01437A) brace stiffeners in place.

Countersinking Seatback Brace

Here is what that countersink looks like.

Countersink For AN426AD3-4 Rivet

This is how the AN426AD3-4 rivet will sit in the hole.

Machine Countersunk Seatback Brace Assemblies

All of the holes to attach the (F-01437A) brace stiffeners to the (F-01437) seatback braces have been countersunk and everything was diassembled and deburred.


Priming Seatback Brace Parts

Before I reassemble all of the parts of the seatback brace assemblies for final riveting, I want to prime the halves of the hinges and stiffeners that will sit against the seatback brace.


Primed Seatback Brace Parts

I primed the parts with Tempo A-702 Valspar primer green zinc phosphate primer.


Riveting Seatback Brace Assemblies

I reassembled the seatback brace assembly clecoing the 13 1/2" (F-1237F) seatback brace hinges, (F-01437A) seatback brace stiffeners, and the (F-01437) seatback braces together in order to rivet each together using the rivets specified in figure four on page 39-03 and per step fourteen.

*Manufactured heads of rivets are to be placed against the seatback brace.

Stiffeners use double flush set AN426AD3-4 rivets.

Hinges use AN470AD4-4 rivets.

Riveting Seatback Brace Assembly

I used our pnuematic rivet squeezer to set the AN470AD4-4 rivets fastening the (F-1237F) seatback brace hinge to the (F-01437) seatback brace.

I also used the pnuematic squeezer to double flush set the AN426AD3-4 rivets fastening the (F-01437A) seatback brace stiffeners to the (F-01437) seatback brace.

Riveted Seatback Brace Hinges

Here is what that looks like. Manufactured rivet heads are on this side.

Shop head on rivets are on this side.


Deburring Seatbacks

On page 39-04 the (F-1237A) seatbacks will be worked on next, I want to debur them before I start working on them first.

Deburring Seatbacks

I peeled off the protective blue vinyl and then washed off the red ink with acetone.


Deburring Seatbacks

Let the deburring begin!

This is how I set up the piece on the workbench so that I could use my file to debur the edges.

*This is the way the seat is oriented in it's position in the cockpit; the narrower side is at the bottom and the wider side is at the top.


Deburring Seatbacks

The straight edges are easy enough to debur, the "fun" part will be deburring the lightening holes.

Deburred Seatback Edge

I want the edges really smooth, don't want anything to be snagged by the seat edges!

Deburred Seatback Edge

Nice!


Deburred Seatback Lightening Holes

I used a small round file and 400 grit sandpaper here....probably "overkill" I guess?


Match Drlling 12.5 Inch Seatback Brace Hinge

As per step one, on page 39-04, referencing figure one, I clecoed the locating hole in the 12 1/2" (F-1237F) seatback brace hinge to the (F-1237A) seatback.

*Just like drilling the other hinges, I drew a guide line lengthwise along the (F-1237F) seatback brace hinge in order to provide a visual reference when I flip the seatback over and start the #30 match drilling, which is coming up next. This line helps maintain alignment of the hinge while the drilling progresses.

Match Drlling 12.5 Inch Seatback Brace Hinge

Here's a wider photograph of the whole seatback.

Guide Lines For Match Drilling Seatback Brace Hinge

In this photograph you can see some of the hinge guide line showing in the center of the guide holes that will be match drilled into the hinge.

Match Drlling 12.5 Inch Seatback Brace Hinge

As per step two, on page 39-04, #30 holes will be match drilled into the 12 1/2" (F-1237F) seatback brace hinge, using the pre-drilled holes in the (F-1237A) seatback as guides, clecoing each hole as the drilling progresses.

*Make sure you have a block of wood to brace the hinge area as you drill because the seatback can flex some while drilling and you don't want that to happen.

Marked Seatback Brace Hinge

All of the holes have been match drilled in the first seatback.

As per step three, on page 39-04, I marked the (F-1237F) seatback brace hinge and the (F-1237A) seatback so that it can be disassembled, deburred, and reassembled in it's original configuration.

Marked Seatback Brace Hinge

I repeated steps one through three for the second seatback.


Priming 12.5 Inch Seatback Brace Hinge

Before reassembling the (F-1237F) seatback brace hinges to the (F-1237A) seatbacks, I want to prime the back half of the hinges before they are riveted in place.
I cleaned the hinges in preparation for priming with acetone.

Primed 12.5 Inch Seatback Brace Hinge

I primed the (F-1237F) seatback brace hinge halves with Tempo A-702 self etching Valspar primer green zinc phosphate primer.

Marked 12.5 Inch Seatback Brace Hinge

This side of the hinges will be primed later when the seatbacks are reassembled.


Seatback Brace Hinge In Position

After the primed (F-1237F) seatback brace hinge halves were dried, they were clecoed back into position onto the (F-1237A) seatbacks as per step three, page 39-04, and figure one of the builder's manual.

Seatback Assembly

As per step one, page 39-05, and figure one, the (F-1237B) upper seatback angles, the 12" (F-1237D) lower seatback angles, and the (F-1237C-L and F-1237C-R) seatback angles were clecoed to the (F-1237A) seatbacks, which from this point forward, are to be called "seatback assemblies".

*Be sure to have all of the parts clecoed in place because there won't be proper alignment of the side angles if they aren't....this is because what will come next in step two, on page 39-05..

Seatback Assembly

Don't forget to cleco the (F1237H) seatback hinge to the (F-1237A) seatback and (F-1237D) lower seatback angle as well.

This will make the bottom half of the seatback assembly a bit more rigid when it comes time to drill #12 holes in the next step.

Seatback Assembly

Both seatback assemblies are ready for step two, on page 39-05.

Final Drill #12 Holes

As per step two, page 39-05, figure one, #12 holes were final drilled in the lower corners of the seatback assemblies.

The #12 holes pass through the (F-1237C-L and F-1237C-R) angles, the (F-1237A) seatbacks, and the (F-1237D) lower seatback angles.

Marked Parts Before Disassembly

All of the seatback assembly parts were marked before being disassembled and the holes were deburred.

Seatback Angles Prepped For Priming

The seatback angles are being scuffed with red ScotchBrite pads in preparation for priming.

*I am scuffing seatback angles for seatback #2 first and after they are primed I will concentrate on the seatback angles for seatback assembly #1.


Seatback Angles Prepped For Priming

The seatback angles for seatback #2 were washed with acetone in preparation for priming.

I am only going to initially prime the parts of the seatback angles that rest against the faces of the (F-1237A) seatbacks. Final priming of all of the assemblies will come later when everything is final riveted together.


Priming Seatback Angles

I masked off the seatback angles so that only the faces that come in direct contact with the (F-1237A) seatback gets primed.

Priming Seatback Angles

I primed the seatback angles with Duplicolor DAP 1690 self etching green primer.

Priming Seatback Angles

I primed only the surfaces that come in contact with the (F-1237A) seatbacks.

I did this only because when I am ready to prime the entire seatback assemblies I don't want to have to go back and scuff the exposed surfaces before I paint the whole assembly....Duplicolor recommends that the primed surfaces be scuffed before applying new primer over old primer, hopefully this will save me from doing that!


Seatback Scuffing

I am scuffing the (F-1237A) seatback for seatback #2 in preparation for priming with red ScotchBrite pads.

*I taped off the edges where the seatback angles, that were primed, will sit. The Alcad aluminum will be plenty of corrosion protection here where the primed parts will cover it.

Seatback Scuffing

Let the scuffing begin!


Seatback Scuffing

Front half of the (F-1237A) seatback is done, now on to the aft side of the seat...I removed the tape so that you can see that the Alcad is still there.


Seatback Assembly

I finished scuffing the (F-1237A) seatback with red ScotchBrite and then wiped the surfaces with acetone.

As per step three, page 39-05, figure one, the (F-1237B) upper seatback angle, the (F-1237H) seatback hinge half, the (F-1237D) lower seatback angle, and the (F-1237C-L and F-1237C-R) seatback angles were clecoed to the (F-1237A) seatback paying close attention to the proper orientation of each per figure one.

Seatback Assembly

Here is what it looks like from the aft side.


Riveting Seatback Angles

With all of the parts clecoed together it is time to start the riveting process. It seemed easier for me to clamp the seatback assembly to the workbench and then support it from the side. I will be using our pneumatic squeezer to set most of the rivets but the (F-1237F) seatback brace hinge half will have to be set using the rivet gun and a bucking bar.

As per step four, page 39-05, figure one, I riveted the (F-1237B) upper seatback angle to the (F-1237A) seatback with nine (AN470AD4-4) rivets making sure that the manufactured heads were against the seatback front side.

*There are two corner rivets that need to be a different size (AN470AD4-7) so be careful here!

Riveting Seatback Angles

This is what it looks like from the aft side. The shop or tails are on this side.

Riveting Seatback Angles

Riveting Seatback Angles

As per step seven, page 39-05, figure one, I am riveting the (F-1237C-L and F-1237C-R) seatback angles to the (F-1237A) seatback with fifteen per side, (AN470AD4-5) rivets set with the pneumatic squeezer.

I start at the center and worked towards the top and bottom of the seatback assembly.

It is helpful to support the seatback with a wood block and also cleco clamps so that the (F-1237A) seatback skin doesn't "pucker" on the sides but lays flat while riveting.

*Be careful here because the corners require bolts at the bottom and the top holes are riveted with a different size rivet (AN470AD4-7) due to the fact that thicker materials are being riveted together.

Riveting Seatback Angles

Here is what it looks like on the aft side.

After these (F-1237C-L and F-1237C-R) seatback angles have been riveted in place with (AN470AD4-5) rivets I am going to finish up the top corners and use two (AN470AD4-7) rivets.

As per step six, page 39-05, figure one, the (F-1237D) lower seatback angle and the (F-1237H) seatback hinge half will be riveted to the (F-1237A) seatback using nine (AN470AD4-5) rivets set with the pneumatic squeezer.

Riveted Seatback Angles

The seatback angles have been riveted to the seatback using the pneumatic squeezer.

*The manufactured heads are facing the (F-1237A) seatback front half and also the front of the (F-1237C-L and F-1237C-R) seatback angles.

As per step eight, page 39-05, figure one, the required bolt hardware was installed, including (AN3-4A) bolts, (NAS1149F0332P) washers, and (MS21042-3) lock nuts to the lower corners of the seatback assembly.

Riveted Seatback Angles

Here is what it looks like from the aft side.

Seatback Brace Hinge In Place

As per step five, page 39-05, figure one, the 12 1/2" (F-1237F) seatback brace hinge half was clecoed to the (F-1237A) seatback in preparation for riveting.


Scuffing Seatback Angles

The seatback angles for seat #1 have been scuffed with red (ScotchBrite) pads and then washed with acetone in preparation for priming.


Priming Seatback Angles

Just like as done with the seatback angles in seatback #2, only the parts of the seatback angles that come in contact with the (F1237A) seatback will be primed.

I finished scuffing the (F-1237A) seatback with red ScotchBrite and then wiped the surfaces with acetone.

As per step three, page 39-05, figure one, the (F-1237B) upper seatback angle, the (F-1237H) seatback hinge half, the (F-1237D) lower seatback angle, and the (F-1237C-L and F-1237C-R) seatback angles were clecoed to the (F-1237A) seatback paying close attention to the proper orientation of each per figure one.

As per step four, page 39-05, figure one, I riveted the (F-1237B) upper seatback angle to the (F-1237A) seatback with nine (AN470AD4-4) rivets making sure that the manufactured heads were against the seatback front side.

*There are two corner rivets that need to be a different size (AN470AD4-7) so be careful here!

Riveted Seatback Assembly

As per step seven, page 39-05, figure one, I riveted the (F-1237C-L and F-1237C-R) seatback angles to the (F-1237A) seatback with fifteen per side, (AN470AD4-5) rivets set with the pneumatic squeezer.

I start at the center and worked towards the top and bottom of the seatback assembly.

*Be careful here because the corners require bolts at the bottom and the top holes are riveted with a different size rivet (AN470AD4-7) due to the fact that thicker materials are being riveted together.

As per step six, page 39-05, figure one, the (F-1237D) lower seatback angle and the (F-1237H) seatback hinge half were riveted to the (F-1237A) seatback using nine (AN470AD4-5) rivets set with the pneumatic squeezer.

The seatback angles have been riveted to the seatback using the pneumatic squeezer.

*The manufactured heads are facing the (F-1237A) seatback front half and also the front of the (F-1237C-L and F-1237C-R) seatback angles.

As per step eight, page 39-05, figure one, the required bolt hardware was installed, including (AN3-4A) bolts, (NAS1149F0332P) washers, and (MS21042-3) lock nuts to the lower corners of the seatback assembly.

Riveted Seatback Assembly

This is the aft side of the seatback assembly.

As per step five, page 39-05, figure one, the 12 1/2" (F-1237F) seatback brace hinge half needs to be clecoed to the (F-1237A) seatback in preparation for riveting.

Riveted Seatback Assemblies

It's time to rivet the (F-1237F) seatback brace hinge half to the (F-1237A) seatback, It is clecoed in place and will be set using our 3x rivet gun with a 1/8" rivet set and 2" x 1 1/2" tungsten bucking bar.


Seatback Brace Hinges Riveted

As per step five, page 39-05, figure one, I riveted the 12 1/2" (F-1237F) seatback brace hinges to the (F-1237A) seatback with AN470AD4-4 rivets, making sure that the manufactured heads were against the front of the seatback.

*I started at the center of the hinge half and worked towards the edges setting each rivet (except the two end rivets) with our 3x rivet gun and a tungsten bucking bar.
The end rivets were set using the pneumatic squeezer.


The two bolts installed in step eight, page 39-05, figure one, were final torqued to 42"/lbs (28"/lbs + 14"/lbs torque drag= 42"/lbs).


Cutting Seatback Brace Hinge Pins

As per step one, page 39-06, figure two, I am cutting two- 14 1/2" lengths of hinge pin from (AN257-P2 or MS20257-2) hinge material used in the fabrication of the seatback braces.

Two Seatback Brace Hinge Pins

A 90° bend will be made at one end of each of these hinge pins.

Bending Seatback Brace Hinge Pin

The bend is to begin 1" from the end of the hinge pin as described in step one and illustrated in figure two, so I made a mark with a sharpie pen.

Seatback Brace Hinge Location

According to were you read, there is a formula to figure out what the bend radius should be when making a 90° bend. One source says that it should be offset 16- 20% of the material thickness, the Standard Aircraft Handbook says (on page 56) that it should be 2 times the material thickness, and the Van's Airforce guys say it should be 1.5 times the material thickness.
The hinge pin thickness is .0855" so I chose to offset the bend 1.5 x .0855"= .128" (roughly 1/8").

*I chose the 1.5" times material thickness because the 16-20% value was more appropriate for sheet material and too tight of a radius, and the 2 times the material thickness seemed like the radius was too large....I'm no expert so use this as you see fit.

Bend Radius Seatback Brace Hinge

This is roughly the 1/8" offset and what it looks like before the bend.

Bending Jig

I made a jig to help make all of the 90° bends consistent.

The short block at the bottom of the jig allows you to place the end of the hinge pin to a depth of one inch.
There are two strips of aluminum to keep the hinge pin in place, the bottom-most strip has a 1/8" radius curve shaped at the end so that when the bending process begins the bend will be uniform.
The edge block on the left keeps the hinge pin from traveling while the bend is being formed.

This isn't a perfect jig but it works good enough for just a couple of bends.

I also drilled a 1" deep hole in the side block so that if you need to "tweak" the bend any the hinge pin will stay in place.

The ends opposite the 90° bends were filed and smoothed to make "rounded" over ends.

Bent Seatback Brace Hinge Pins

This is what the 90° bends look like.

Seatback Brace Hinge Pin Install

This is what the hinge pins look like when installed in the hinge on the seatback brace hinge.

Seatback Brace Hinge Installed

This is the seatback hinge brace installed onto the seatback assembly.


Cutting Seatback Lower Hinge Pins

As per step one, page 39-07, figure one, four- 5 1/2" lengths of hinge pins need to be cut from the (MS20257-3 or AN257-P3) hinges.

*I cut the hinge pins to 5 5/8" lengths so as to account for the 1/8" radius offset.

Bends In Seatback Lower Hinge Pins

Using the same bending jig, I made four- 90° bends in the hinge pins.

The ends opposite of the 90° bends were filed and smoothed to make "rounded" over ends.

Seatback Lower Hinge Pins Installed

Here is what the pins look like when installed into the lower (F-1237H) seatback hinge.

Scuffing Seatback Brace Assemblies

I am scuffing the seatback brace assemblies with red ScotchBrite pads in preparation for priming.

Preparing Seatback Brace Assemblies For Priming

I cleaned the seatback brace assemblies with acetone and they are ready for priming.


Seatback Brace Assembly Primed

The seatback brace assemblies were primed with Duplicolor DAP 1690 self etching green primer.

Seatback Brace Assembly Primed

The seatback brace assemblies were primed with Duplicolor DAP 1690 self etching green primer.


Paint Stand

Before I primed the seatback assemblies I built a new paint stand.

This is the I stand; it can easily handle larger items and is built using a total of five- 2" x 4" x 8' studs and four- metal 8' studs riveted together.

Two metal (riveted together) studs are used for the top cross piece and two metal (riveted together) studs are used for the bottom cross piece.

The frame is 6' tall and has 2' cross "feet" for stability. The top and bottom cross pieces are held in place with 3/8" bolts to prevent the structure from separating while in use.


Clean Seatback Assemblies For Priming

The seatback assemblies were cleaned with acetone in preparation for priming.


Seatback Assemblies Ready For Priming

The seatback assemblies are ready for priming and as you can see there is plenty of room for both of them to hang from the same paint stand.

*I added some extensions to the top and bottom braces and now the stand can handle a piece 11' wide....maybe a horizontal stabilizer?

I needed to finalize the forward movement on the control sticks by adjusting the control stops.
As per step one, on page 36-13 of the builder's handbook, the forward portion of the (F-01450-L and F-01450-R) left and right bearing brackets which limit the motion of the control columns, when deflected, were filed so that movement was within proper limits.
The forward limits of the right and left control columns are now 13.65°. The aft limits are now L= 24.05° and the R= 24.20°.

*The left and right bearing brackets are described on page 25-03, figures 2-4 of the builder's manual.
