Harvesting the carcass

I'm similar to Post #6. I drill the welds thru with an 1/8" then drill part way again the a 1/4" bit to weaken the weld , then seperate with a Chisel and hammer or wide scrapper. You'll find some spot welds are big. With those I use 1/8" again and then use a blair cutter (wider) and only try to cut through the top layer. And then you guessed it, I use hammer and chiesel unless your good and careful with an air chisel which I don't recomend.
