In the continuing saga of trying to get the top pop rivets in for the spar to rib connection, I hacked down the nose adapter of the pop rivet tool. This sucker was really hard! I destroyed two brand new metal cutting hacksaw blades trying to cut through this thing. I got about 80% of the way through with the hacksaw then just used a chisel to wedge in the gap and pop the tip the rest of the way off. After a little work with the sander and the scotchbrite wheel, it looked nice and smooth like this. Unfortunately this didn't really help. Gonna have to figure out another solution to get on those rivets.
