[QUOTE="BigTerp, post: 421836, member: 9169"] If you're using the proper size and style of rivet tool for those rivets and still getting those circles around the base of them, I'd guess your air pressure is set too high. Might be high enough for the heads of the rivets to smash down and deform outwards, if that makes sense. Then your subsequent hits with the air gun puts the little circle in them. FWIW, when I set my air gun for rivets I'll take it to a piece of non pressure treated 2x4. I'm looking for the tool to just make an indention in the wood. If it smashes through the wood the pressure is too high, if it doesn't dent the wood, the pressure is too low. My compressor is old and the gauge isn't very accurate. So I do this every time I start a rivet job on my boat. [/QUOTE]
