I started this morning rolling the leading edge joint to help it lay flat after it is riveted. Then I moved onto scuffing the rivet lines on all of the right aileron parts and then dimpled all of the skeleton and part of the leading edge skin. I also countersunk about half of the counterbalance to leading edge skin rivet holes per the plans.

Countersinking the counterbalance weight (pipe) for the right aileron - the steel isn't as easy.
