top aileron rivets

[Shockwave]

How did those with a 7 or 8 kit rivet on the leading and trailing aileron skins to the spar? I have a few rivets in using the pneumatic squeezer and then a few more with a regular gun and bucking bar but I'm at a point where I can't get the bar on well. I'm thinking maybe a double offset backrivet set might work, but I'd like to hear everyone else's thoughts.

I designed a special bucking block. One of my friends cut it out for me on the wire EDM machine at work:


The square-ish hole in the middle fit onto a 1/2" x 2" x 6 ft steel bar which I slid through the length of the aileron:




Sliding the block along from rivet to rivet allowed me to install solid rivets on both the top and bottom surfaces:


Good luck!
