First Rivet a Bust

So, I set my first rivet of the project today, and sadly it will need to be removed and redone. I've been waiting for the last several days to get the lacquer thinner I needed to clean up after shooting my primer. I finally found a Sherwin Williams this morning that had the required thinner, and proceeded to assemble my spray booth for the garage. I would much rather spray outside, but it's too cold, and was in fact snowing this morning. After assembling the spray booth and priming the VA-145, I was ready for the first rivets.

I have read of many builders who have used AN470AD4-6 rivets, as opposed to the AN470AD4-5 rivets called out in the plans, to rivet the HS-411 assembly. I checked the pre-set length of the -5 rivet using my rivet gauge and sure enough the -6 does appear to be the correct length. So I moved up to the longer rivets.

I set up my pneumatic squeezer for the 1/8" standard rivet. As soon as pressed the lever the rivet proceeded to fold over, a sure sign of a rivet that's too long. I'm not sure if I had the squeezer perfectly aligned for the rivet or not. That may or may not be the cause of the poor set. After I drill out the faulty -6 rivet, I think I'll another -6 rivet, but use a rivet gun and bucking bar as opposed to the pneumatic squeezer.
