Has anyone seen cracking in the rivet shop head during the forming process? I have a batch of AN470 AD4-5 rivets where I occasionally get a tiny crack on the circumference of the shop head. In this case, I'm using a pneumatic squeezer. This is the first time I've seen this and I'm well into the Fuselage. I worried about the crack propagating and destoying the integrity of the rivet. I checked with Van's and although they didn't have any idea what was causing it, they didn't think it would be a problem. I just wondered if there was anyone else out there that had any experience with this sort of problem.
