About 15 years ago I was visiting the shop of an old fellow who rebuilt shop machinery, who is no longer with us. We started talking about metal cutting bandsaws, and I didn't see one in his shop so I asked him why. He picked up an old file and walked over to what I thought was a woodcutting bandsaw--and with sparks flying, ripped right through it in less than ten seconds. Can't remember what kind of blade he used, whether it was bimetal or carbon but I do remember that the blade tension was very high, as was the speed. Anyone use this friction cutting method for metal?
