Finished the backriveting of the bottom skin and started assembly of the left aileron. It all went together easy and I set it up on a very straight door blank that I used to build RC planes on. Laid it flat on the board as described in the plans, but then they say to cleco the trailing edge wedge in place. How to do that with the aileron flat on the board?Decided to use my spare aileron skin to pre-drill holes in the door for the clecos. Then got the aileron back in place and cleco'd through the door skin. Everything looks good and straight. Drilled the trailing edge using the angled wood block I made long ago for tail feathers. So far so good. Disassembled everything. I could tell the skin stiffeners were conflicting a bit. I trimmed the ends a little more with snips and filed them smooth. 8/16: got everything dimpled this morning before work. Still not sure about proseal vs tape method. 8/17: countersunk the trailing edge wedge and riveted the spar doubler.
