There has to be an easier way. Replacing panels on my 66 Corsa Turbo Conv. Everthing on that car is held together with spot welds. I have burnt spot weld cutters up like they are free. Recip-saw blades (even high dollars cobalt) don't do it. I'am using a 26/64 pilot drill bit now with a copper pipe over it so that only about 1/16th. of an inch is showing. slow process. Corvairs must have about 100 spot welds in each panel. What is the best way to get them apart? The spot welds are not round either. they are more like an egg shape. Talk about a project. Any tips?
