6 hrs, 48 rivets
Worked on the left wing aileron and flap attach hardware. These tasks take a bunch of time, and use just about every tool in the box.

Match drill, debur, and prime aileron attach brackets. Was getting ready to rivet, looking at the plans for the details, when I realized there were some 426 rivets called out. So had to do the countersinking after the parts were primed. Then used the squeezer for most of the riveting. Only needed to shoot the rivets closest to the top skin, since the longeron yoke wouldn't reach.

Also countersunk the parts for the right wing.

Match drill inboard and outboard flap attach brackets, and then prime them. Primed these parts and all the aileron bracket parts in one batch.
Went for a run and ate lunch while the primer set up.

Then riveted flap attach brackets to ribs.

Align and clamp middle flap attach bracket, and then match drill to rib.
Debur ribs and middle flap attach bracket.

Match drill inboard and outboard 925B and C angles. Machine countersink the C parts for the hole that matches the spar flange.
