Printed more radiuses and tried shaping rivet gun nose

I printed more radiuses including two color coded ones that match the ones that most parts in the plans have to allow for adequate bending without cracking of 6061-T6. Planning to always check my form block round-overs and brake bends with these on hand going forward.

I attempted to use the techniques several YouTubers show for shaping the rivet gun head in the manner that Zenith uses for their assembly methods. I thought the A5 attempt turned out ok, until on closer inspection I realized the concave bit I had was off center and setting rivet heads unevenly. Even if I'd managed to get it machined centered, I think this is terrible advice to suggest people do considering 1. Zenith doesn't specify the radius for the round out in their construction guide. And 2. Zenith offers to do this on your tool's rivet heads for free.
