i am using a harborfreight floor model metal cutting bandsaw with i believe a 10-14 tpi. the bandsaw it probably 10 years old and still cuts nicely, 1hp motor current model number is 93762. i am cutting 1/4" thick 6061 T6 aluminum plate. i did cut some 1/4" and 3/8" thick 6061 T6 aluminum plate on my dewalt 12" slider power miter saw with 60 tooth carbide tipped blade. oh how thick a piece i can cut with this bandsaw, 4"x6" thick, after the cut it trips a toggle switch and turns off. i have cut a 1 3/8" solid steel shaft before, it cut through it like butter.
