Finished riveting the counterbalance skin to the rudder skin and spar. I installed the tip rib and began riveting the skin to the spar.

I used the squeezer for most of the rivets on the skin. I only riveted about half way back on the tip rib and the bottom rib because I wanted to be able to split the trailing edge without bending anything.

I decided to use epoxy for the trailing edge. I split the TE and placed a glob of RTV at the stiffeners and then applied the epoxy to the AEX and the TE skins and clamped it all to an aluminum angle to keep it straight.

Looks pretty good so far. Lots of opportunity to build in a twist when riveting so it's not over.

After all the clecos were removed I took a look at the TE. Overall, i'm pretty happy with it, so far. There is some "pillowing" between the clecos where the epoxy didn't squeeze out uniformly. I tried to correct this while it was wet but I missed a few. I don't think it will be noticeable.

Rivets in place and taped. But first....

I took the time to inset my new back riveting plate as recommended. This one is from Cleveland. I used a plate that I found at the aviation department of Lowes but it was much shorter, thinner and I didn't inset it. Consequently, I had a little pillowing around some of the rivets in the rudder stiffeners that shouldn't have been there. Maybe this will help.

I think it came out pretty straight. I tried to follow the riveting instructions exactly.

Next I had planned on building the H stab. Some of you building second hand kits know, you can't be sure what your buying.
This is the H405 inner tip rib. It should have two equally spaced holes in it through the front spar. Yes, it has too many holes too. I decided the best way to fix this is to order new parts.

Next, I started the right elevator. I cut and shaped the stiffeners. This went much faster than the rudder. It's pretty much the same thing. I prepped them for assembly, primed them and back riveted in place.

After buying the right back riveting plate and insetting it into the table, the rivets looked much better.

No pillowing like i had on the rudder skins.

Next I started assembling the skeleton. After the rudder this seemed to make sense.

When I tried to attach the skin to the skeleton I had a real fight trying to get the skin to lie down. Re-reading the instructions, I discovered I missed the bend the trailing edge step.

It took a couple of tries but I finally got the bend right.

Next, take it all apart and prep for assembly but, before that I applied the SB for the spar.

Then the primer.

Then reassembly.

I used the squeezer for the rivets where I could. I pulled the rivets in the trailing edge positions.

One side down, one to go.

Nice work, Vern. I made it over last month but only for a night and didn't have time to contact you. A retired Army friend and Chinook pilot at Rucker lives nearby. He and his son (studying for his A&P) are considering a -14 build and I suspect they'd like to stop by and chat with you. If interested in a visit, PM or email and I'll pass on their contact information.

Its been awhile since I posted. Ive been building but life and the temps in the shop slowed me down. Getting a little more done now.



Starting on the left elevator. Prepping the skins for the stiffener.



Before I fastened the stiffeners to the skin, I thought I would try to bend the trim tab close out on the elevator. I was not looking forward to this and I was not disappointed. Yup, tore the skin. I folded the top tab then the lower tab. This is reversed.

When I tried to unfold and refold the skin tore. My fault. New skin.



new skin on the way so I will continue the build up of the skeleton.

Didn't get very many pics but the new skin is here and stiffeners attached. Fitting the trim tab servo doubler and cover plate.







That should work.



assembling the elevator one more time.



Couldn't get the folded tabs to look right and, having already replaced the skin once, I decided to cut the tabs off and go with riblets. This pic is the initial fit. I decided to reverse the rib so it is flush with the elevator cut out.





Fitting the trim tab hinge. You can see the riblet. This tab is the most frustrating part of the build so far. I know, I know..."just wait till..........."

Not a lot of pics on the tab. It is fitted and it looks good. Not great, but good.



The gap came out pretty close. More importantly, the TE is spot on.





Now on the the HS.

Starting to assemble the HS forward spar.



HS forward spar with ribs attached



Skin in place and ready to rivet on.



view of forward spar with AD doublers installed. Glad I didn't have to take one apart to do this.
