I finished up the aileron pushrods on both wings. Then I started on the bottom skin on the right wing. Everything lined up really well. I got it drilled, clecoed ... then updrilled for rivetting. Since the channel brackets for the bellcrank have to be drilled from the inside I did that. I have to pull it back off and debur everything, shoot the contact areas with zinc chromate, and then rivet it. I started drilling the top skin on that wing. I left the bottom on to hold things in alignment. When done drilling the top I'll pull the bottom off ... drill the top side of the bellcrank support channel .. put the bottom back on and rivet it ... pull the top .. debur it .. then rivet it on. I'll then repeat the process on the left wing. I would have done the of the left wing at the same time .. but I don't have enough clecoes. There's a lot of rivets in the wing .. lots of holes to drill and debur.
