If I used the rivet gun too early, the rivet shaft tended to bend over, leading to a mis-set, drill out, and new rivet. Using the hammer in one hand and a torch in the other made alternating back and forth easier and I ended up with a better finished rivet. Don't know whether any of this will work for you, but it's what I found to do the job and make them look like original. Hope this helps! --Don
Hi Don:

Thank you. It does makes sense. Some of the "test" rivets did exactly what you described.
All my tests were set cold. I do think some of the rivets were a tad too long as well.

I do like the idea of a rivet gun and being able to feather the trigger vs. an air hammer that tends to come on full blast; even with a regulator.

Hope to get to it soon and I'll report back afterward.

Tim
