Ok, ok, what you are proposing is not a one man operation. Structural steel riviting was a three man dance that they did on bridges, building skeletons or any of the large steel fabrications. You had the catcher who placed the hot rivets, the bucker who bucked the backside of the rivet and the riveter who handled the pneumatic hammer. Of course in the factory they had very large dedicated hydralic anvil riveters to close the rivet cold. Any one that has seen the Jam Handy films from the 30's has seen these in use.
So Deve, If you are serious about totally dissasembling a frame and reriveting it, you will need the pnumatic hammer, a bucking bar and someone to hold it, a rivet heater and someone to place the rivet since you've only got a few seconds to drive it before the frame suckes the heat out of the rivet.
This is a very BIG project you are thinking about attempting. Driving a few rivets is bad enough but a whole frame is a monumental task.
There is a lot of information on the net about hot riveting, here's a good starting place:
