Assembled the right aileron. When I put the left aileron together I back riveted the AN426 rivets with an offset back riveting shank. It worked okay, but I had to redo about one-third of the rivets. For the right side, I built a little holder and put the aileron's upright. Then I held the skin out of the way and was able to reach in with a bucking bar. It was much easier and I only dinged one rivet when I let the rivet gun skip off the manufactured head.
Finished the ailerons and put them on with wing with zip ties to get them out of the way.
