After a long week of travel, I managed to sneak in the shop tonight just before bedtime.

First up, finish prepping the reinforcement plate. I’m using oops rivets here, coutnersunk, instead of trying to dimple the nutplate attach holes on the plate and the nutplate ears.

Then, the boring task of edge-finishing, deburring, and dimpling stiffeners. This is after four of them, but I think there were 16 total. Maybe only 15.

Ahhh, yes! I finally get to use NAPA self-etching primer. Guys, it is so much better than the walmart stuff.

1.5 hours of stiffener prep.
