				| Problem rivets
 There are 4 rivets on each side of the aileron where a regular flat bucking bar won't fit because of the stiffeners on the inside of the top flat skin. I had to fabricate my own special fitting bucking bar in order to buck these rivets. It took me about an hour to grind this dude down with a grinding wheel and then smooth it over with the the scotchbrite wheel. The results were perfect for these problem rivets.
