5.2 hrs 204 rivets
Started aileron final assembly. Got a fair way through both ailerons, and further on the right.
Riveted reinforcement plates to spars
Riveted main ribs and nutplates to spars

Riveted nose ribs to counterbalance tubes

Riveted nose ribs to spars.

Cleco top and bottom skins to frames
Cleco leading edge skins to frames
Rivet leading edge skins to nose ribs and counterbalance tubes.

Then commenced with riveting the right skins to spar. This is hard to do and get right. I had to drill out a couple of perfectly good rivets because I wasn't happy with the fit between the skins and the spars. If there's any pressure at all pulling the aft end of the skin out during riveting, it won't set right. Had to be creative with some of the rivets that line up with the stiffeners. Ended up using the corner of the angled bucking bar to get some of those. This used a face of the bar that's not polished, but it works better than anything else I could come up with.
Also set rivets for the right skin/ribs. Next up is the trailing edge.

I'll get the left aileron up to the same point before starting the trailing edges.

Chose an easy task for the end of a long week. Peeled plastic from the flap ribs.
