After reading everyone’s advice on the RV7and7A Yahoo Group, I decided to try resurrecting the small aileron push tubes. I first tried drilling out one of the rivets. Drilling out the manufactured head was easy, but it wasn’t enough to free the rivet. I also had to drill out the shop head. That was tricky, but not too bad. After drilling out both sides, I had a chunk of rivet still rattling around inside, I had to take the end off to get the junk out.
I drilled out all of the bad rivets, and then tried squeezing -11 rivets with the tube held in a vise. Worked like a charm. They still aren’t the most beautiful rivets around, but they will hold just fine. I cleaned the extra primer off the outside of the tubes with some MEK, and they look great.
I also dimpled around the edge of the right inboard bottom skin and started deburring the right outboard bottom skin.
