This log entry represents work done over multiple days, though they were very light-work days due to needing to spend some time on other tasks around the house (including some drywall and plumbing repair in the guest bathroom, assembling a backyard gazebo, and throwing a taco party for friends).

After receiving a new foot shaped bucking bar, I was able to buck those remaining rivets on the inboard edge of the rear spar flange. The angled tip of that bucking bar was narrow enough to squeeze past the doubler fork. I also riveted in the last nutplate on that inside trailing edge.

I also received some drilled head bolts to replace the ones that came for the aileron bellcrank bracket, so that I could safety wire them. Interestingly, the new bolts have a slightly longer unthreaded portion of the shank than the original ones, even though I ordered the size that was described in the instructions. It's possible that Vans has been shipping out slightly shorter bolts than what the instructions say. The longer ones still seem to engage properly but they do protrude out the rear side (of the tie-down hook bracket) a little more than necessary. I only did one of the two brackets on this wing, since the other side still has the skin clecoed in place for alignment purposes.

Then I got back to installing flush rivets on the inboard top wing skin. I finished another couple dozen rivets or so, completing up through another rib section of the wing. This time I tried flipping the wing down on its side so that I could reach around the main spar and buck the underside of the rivets. This angle is quite a bit more difficult because I can only use feel to position the bucking bar, and I have to get on my knees and look up in order to inspect each shop head. It also took a few rivet attempts to get used to this new riveting orientation. I may need to enlist a riveting buddy to finish the majority of these rivets, or try a different angle.
