band saw speed for metal?

Other than jackshaft and more pulleys I got nuttin. Any high torque output electrical speed reduction for a single phas motor is going to be expensive, and might not be that efficient. Some motors might not work at all without problems.

An example is, "when I was a kid" and first got into amateur radio, there was still a fair amount of aircraft 400hz AC stuff around. You can NOT use those items on 60hz ac, the core structure just won't hack it. They heat up and die. I would imagine the same thing would happen to a 60hz motor operated way below design frequency
