-Finished backriveting all the pieces except for the 4 corner steel brackets.
-Drilled out and re-riveted a couple oops
-Started backriveting the 4 corners. Ended up using my long backrivet set so I could stay straight on the rivet (the gun would hit the tall flanges). The plans have a mistake in them. On one part of the plans it calls for -6 rivets and then -7's on another, even though it's all the same thickness of parts. After smashing some -6's, I determined the shop head was getting a little thin, so I had to drill some out and make them all -7's. Then I bent a few over and had to drill those out. Geez, seems like I'm a little out of practice. Will finish these tommorow.
