I started out trying to buck those remaining 5 rivets on the inboard most edge of the rear-spar flange. The slack group recommended using the angled tip of my bucking bar, and although that did let me get 3 of those rivets, the remaining 2 need a sharper tip than my bucking bar. So, I think I'll probably have to find one of those foot-shaped bucking bars and try these later.
Then I made some progress riveting on the nutplates on the inboard edge of the wing. Because I chose to dimple the ribs in the wing-walk area (rather than countersinking the skin), I had to also dimple the nutplates and use slightly longer rivets here too. I also made a little more progress bucking rivets on the skin up to half of the next rib.
Next, I decided to take a break from the skin riveting and work on preparing the replacement aileron hinge bracket. This involved some bandsaw work to cut apart the pieces, belt-sanding, smoothing on the scotch-brite wheel, and scuffing with scotch-brite pads. Then some counter-sinking for flush rivet holes, cleaning, and priming the parts. Finally, I used my hand-squeezer to install the rivets, then clecoed the assembled bracket into place.
What's next? Probably more skin riveting, and maybe attempting to rivet in this aileron hinge bracket into place.
