This is a follow up to this thread http://www.vansairforce.com/community/showthread.php?t=113098
I clipped one of my pictures and blew it up to show what happens when a rivet is installed. We think the hole is round, and it is, but it also has some angled portions where the sheet metal is bent down during dimpling. The effect is that the rivet expands into this angled area and really does lock the metal pieces together. it is easy to see how secure a well riveted piece really is.
I am not a great photographer and I would like to see what someone with a good camera can do. Use a die grinder to cut through a set rivet and then buff the part on the 3M wheel. We could get some shots of different rivets, countersink, dimple/countersink etc. I think it would generate a useful discussion
