Hot day, but knocked out the right rib priming through the day. Disassembled the ribs from the spar, final deburr of all the ribs, then prep and prime. Just a lot of work. Hopefully that's the last big batch of priming for the wings. I'll need to go back and prime that replacement rib when it shows up, but I think I can move forward. Got all of the ribs cleco'd back in place on the spar. 5/10: Realized I forgot to prime and assemble the miscellaneous rib pieces. Snuck in a quick priming session after the kids were in bed. 5/11: Got the flap brackets and aileron torque tubes riveted. Found it was easier to rivet the torque tube brackets to the angle and the rivet the angle to the rib, contrary to the instructions.
