Brief Description: Riveted bottom and part of top skin flange
After a long day of building, I couldn't resist starting to rivet, so around midnight I started to rivet. I decided to do the bottom first, and all went well. I turned things over and merrily started to rivet away. Only after I had done about 30 rivets did I realize that I was riveting the top flange without having the piano hinge in place. Ooops. By that point, I was beat and mentally exhausted. I left learning the fine art of rivet removal for another day.
