band saws

Started work life in a machine shop running a pair of production horizontal DoAll saws. Also along the way I used a 16" vertical DoAll I used almost daily. Good stuff, especially when you have the blade welder. You'll need some space and adequate electric supply.
My home band saw is a Craftsman with floor base 12". It's OK...……Lol, for wood. I've seen speed reducers available a while back but never pulled the trigger on one.

Yes sir, I was with a contractor in a large plant and they gave us access to their machine shop, mostly DoAll, my goodness what dream machines. I could throw up a sheet of 16ga on the vertical, and rip through that stuff like butter.

My home saw is the same as yours, I got a gearbox and rigged it up and it went too slow imo. Buy the big$ steel cutting blades for it and tried on sheetmetal and it immediately commenced to chunk a tooth or 2 @ the splice, then the more you cut the more they went to a Ka chunk Ka chunk. Got frustrated and slid it against the wall and haven't touched it in years.
