I got the ribs deburred and primed. I also countersunk the main spar and primed both spars. I had to make my own female side of the dimple die in some heavy gage angle material. I used the rivet gun attachment to hit it from the top side. They came out ok. I also had my friend Chris come over with his son Brian to do come metal work on the invention convention ide he had. It was a lot of fun.
