60 cycle AC makes motors run 1800 rpm at the shaft. You can do "anything" with a variety of belt pulleys. Does the old Craftsman have the two adjacent speed-control 'cones" of pulleys that you can change speed with? Between that chart that FearNo posted and a pencil & paper (I'm joking-- an electronic calculator) you can figure out the pulley ratios and get any speed you want. The bandsaw itself won't care what it's cutting if you set the other guides and the band tension to spec.looking to mostly cut brackets so id say anything from about 1/8 to 1/4 steel. there is no motor on it now but we have like 50 motors that would fit. would horsepower matter or anything i should shoot for?
If you ever stumble across a Variac at a swap or something, pick it up. Mine cost me $15 10 years ago. They're great for that kind of thing, knocking down the speed of AC motors.could prolly wire in a potentiometer for speed control
I tried the Treadmill motor before I did the Jack shaft and it wouldn't give me enough torque. I got all the pulleys I needed from Mastercarr. If you research making a jack shaft it's not hard and you can buy everything you need. Very little fab work.
Loffer I don't think that will lower the speed enough. I'm horrible with math, but there are ways to figure out exactly how fast.[/QUOT
Depends on waht type of saw you have. Mine is geared down to begin withand coukdbt be more than 500 to 700 rpm to begin with its has 3 belts and a gearing system after the motor before the drive belt. I may not ever know cause I have a mac plasma cutter but I might still give it a shOt.
