Finished the Elevator

December 15th and 16th 2018, 10h

We pop riveted the remaining hard to reach rivets
we rolled the leading edge of both the left and right elevator
We riveted the leading edge of both the left and right elevator. It was a bit tricky to get the two surfaces to mate smoothly together, we had to do additional adjustment to the bend at the area where the two surfaces meet, and by the end we got some pretty good results.

Then we attached the elevator to the horizontal stabilizer, we had to adjust the number of rotations of the bearing to get good range of motion. We have now bigger than the max 30deg range of motion, which we can reduce later on. We also had to remove a little bit of material from the horizontal stabilizer to make room for the horns, to get the large range of motion.

The empennage is looking pretty good, time to move on to the wings.

Finished the Trim Tab

December 14th and 15th and 16th 2018, 10h

We primed the trim tab.
We riveted the trim tab.
We attached the trim tab to the elevator by riveting the hinge to both the elevator and the trim tab.
We attached the trim servo and adjusted the length of the the rod

We have a pretty good range of motion of the trim tab

Elevator Riveting and Trim Tab

December 8th and 9th 2018,11h

We finished the elevator skeleton riveting.

We riveted the elevator skeleton to the skin. We missed putting RTV at the trailing edge where the stiffeners meet, which is because it was not specified in the instruction, but it is recommended by Van. I checked with Van and they said that it is ok to proceed and that the elevator is air worthy without the RTV.

We still need to do few rivets that can not be reached with the pneumatic or back riveting, I am ordering some more flash pop rivets for those.

We started working on the trim tab:

Match drilling
Deburing
Dimpling

Started Riveting the Elevator Skeleton

December 1st and 2nd 2018, 3h

We started the elevator skeleton.

We riveted the trim system

We riveted reinforcements plates to the spar

We riverting E-703 to E-704

Left Elevator Prep and Trim System

November 30th and 26th 2018, 5h

I did counter skin the left elevator in the various locations it was called for.

I prepared the trim system:

I spent a lot of time trying to determined where this 2. I called Vans and this 2 pieces are extra from another airplane, they were left in my trim box by mistake.

Making the Holes in the correct location was tricking, but it worked out in the end with the use of a lo of clekos, clamps and testing throughout the drilling.
Also, I had to make few modification to the access plate so that the trim system can go in and out easily.

Then I looked into bending the sides of the elevator, where the trim tab will get places. For that I need to cut a piece of wood with the taper of the elevator. I don’t have any equipment to cut wood, so I went ahead and bought a band saw. Screen Shot 2018-11-30 at 6.15.15 PM.png

Left Elevator Prep and Priming

November 24th and 26th 2018, 8.5h

Left elevator prep:

I deburred all the parts.
I smoothed all the edges.
I dimpled all the parts.
I cleaned all the part with Acetone.

Then, I primed all the parts. I had to extra mix the primer given how tick it became. Based on Stewart System, it is normal for EcoPoxy base to become pretty tick and chunky. After the extra mixing, I was able to get good results.

Left Skeleton Elevator Prep

November 19th 2018, 5h

I prepared the skeleton for the left elevator:

matching drilling the reinforcement plates
match drilling spars and ribs
match drilling counter balance skin
installing the counterbalance weight
match drilling the skeleton to the skin
match drilling the horn

Right Elevator Priming

November 17th 2018, 4h

I primed all the parts of the right elevator. The primer base become way too tick, after mixing, the primmer still had some lamps, which clogged the spay gun. Afterwards I mixed the primmer more and was able to get rid of the lamps. I still need to follow up with Steward System to see if the primmer based is no longer good.

Right Elevator Prep

November 16th 2018, 4h

I disassembled the right elevator assembly. Then, I finished dimpling and counter sinking all skeleton attachments to the skin. Afterwards, I deburred and smoothed all the edges. Then I cleaned all the parts with acetone, so they are ready for priming.
