Has anyone had the machined head of the rivet break off while setting a rivet? I am working on attaching my ribs to the main spar and I have had 3 break off. It has looked like it sheared level with the flange of the rib. I am using the double offset. The broken head shows no smilies.
This is the second spar and I had no problems with the first spar but now wonder if there is a problem I should be concerned with. I compared the double offset rivet set to a straight set and it appears the double offset is a little flatter at the bottom of the cup than the straight set. I switched to the straight set and the rivet heads appear to be better.
My main concern is whether or not the ones that didn't break off are structurally sound. They appear a little more flattened (very slightly) but I am cautious about things like this. The thought of drilling out every rivet in the main spar scares me. Any thoughts would be greatly appreciated.
Thanks, Joe
