Update! I got all the stuff together, OA Torch with a medium rosebud, Cheapo Air Chisel, Rivet Setter for the air chisel, homemade bucking bars, clamps, etc and IT WORKED FLAWLESSLY!! The very first rivet I set looks as good or better than some of the rivets that Chevy did back in the day. I will write a complete procedure on how to do this forthcoming. My wife took all the pics we needed for the procedure, so I should have it done soon. FYI, I heated the part of the rivet that was sticking out the hole (3/8 rivet) very very red, then drove them home. After I did a few, I let them cool, took a pair of heavy vise grips and tried to turn them in the hole. Fuggetaboutit!! Nice and tight. So, just to appease my friends here (and myself) about this procedure not heating the entire rivet thus not a good tight fit, I ground off the head clean, then tried to punch it out of the hole. It was completely squashed HARD into the hole to the point where I had to use a very large punch and a very large hammer to get it out. It took several hard swings to get it out. VERY VERY STOUT. The reason this works so well is the rosebud head on the torch. It not only heats the rivet, but the hole and to an extent the surrounding metal. The rivet squashes to look just like any of the rivets on the frame. You cant tell the difference! Just thought you all would like to know! (The air chisel I used was a BP Tool (very old) that I had sitting around the shop. My dad must have bought it and there is no part number that I can find. Good news is, you dont need a very heavy air hammer/chisel for this.) More coming soon! Thanks to all of you who helped with my stupid questions!
