band saw speed for metal?

Sure, I'm aware of that but your cutting speed seems really low? I thought it was like 250?
"A1008-A1013 cold rolled sheet: 250 (sfpm) blade speed 8-10 (sipm) cutting speed"
Im cutting up to 1/4 and down to 16g, but 1/8 is what I expect to cut the most of. With this setup I should be able to get it pretty low. Nice thing about DC is you dont lose torque down low, think Tesla. You can rip through thin AL it a pretty fast rate.
