Brief Description: Rivet Bottom Skin on LH Aileron
I clecoed the bottom skin and trailing edge in place and checked for twist. It had 0.1 degrees according to my digital levels, but I'm not sure they are that accurate. I laid the aileron top surface down on a flat table and saw no discernable twist or rocking, so I started riveting on the bottom skin per the Section 5.8 of the plans.
I did run into a problem in the tight area on the inboard end of the skin. The nose skin doesn't go all the way to the end lengthwise, so you have this little area that you can't really get a mushroom head set in there. I fabricated a 0.025 in. thick spacer from some scrap that fits in the gap to give a flat surface. My first try resulted in the worst looking rivet I've ever set with the head at a 20-25 degree angle. Drilled it out and the second time I got a very good result.
Riveting the LHS bottom skin in place after checking for twist
I couldn't fit the mushroom head in this space and I got a really bad set on this rivet
The fix was to create a spacer our of 0.025 in. scrap to give a flat surface to rivet on
