After yesterday's successful riveting session on the top wing skins, i now had to finish out the last few steps in this section. The first thing that I needed to do was rivet on the outboard aileron hinge bracket to the outer-most rib. After clecoing the bracket in place, I had to match-drill 3 more holes and then disassemble and debur. Riveting the bracket in place was doable entirely with a long-reach yoke on my hand squeezer, though I had to do some slight modifications to my yoke.

The long-reach yoke I used came with my Numatix squeezer, but the hole for the squeezing piston was just barely too small for my Main Squeeze hand squeezer. The hole was supposedly 3/8" but perhaps just slightly under. I ended up using the 3/8" ream (that I use for the main spar holes) to slightly enlarge the hole in the yoke a little more and that worked to allow the yoke to fit.

Next, I had to countersink the holes on the inner-most rib to allow flush #8 screws to be eventually be installed there. These holes were relatively deep, but used the same test jig that I had used for the fuel tank screwholes so this wasn't too difficult.

What's next? I think I need to get back to testing the fuel tanks for leaks, since I'll need to soon start joining the fuel tanks and leading edges to the wings.
