Brief Description: Ailerons - Spar Reinforcement Plates Match Drill
Match drilling is straight forward except there are a few #12 holes through the steel aileron hinge bracket and I needed to clamp it and drill it on the drill press to ensure it didn't move, and was straight through. I found these really cool clamps in the bottom of my clamp drawer. I bought them a long time ago when Boeing surplus still had a store. They work pretty good.
The holes in the aileron brackets look good. They are centered and look like they are in the proper location.
Then, per plan, I debured, primed and rivetted the reinforcement plates onto the spar using only the three most inboard holes. The other holes will get used with the nose rib and main rib.
