gear motor powering vert.BS ????
I need some opinions on a project. I have an older Mont. Ward 16" wood
vertical bandsaw that Im converting to metal. I have a Leeson DC gear motor, will it work? I have the speed controller also. It is 40 or 45 to 1 reduction, but only 1/4 hp, about 62 rpm. Will this have enough power and torque to cut metal? I have never been around these motors before, so its all new to me. Thank you, Craig |

Probably not. Even with the gear reduction, at 1:1 on the saw wheel,
you're running about 75fpm, but you're loosing a lot of mechanical advantage because of the diameter of that wheel. It will work, but don't crowd the blade. I'm afraid it will stall fairly easily. I've looked at using a reeves drive from an old hospital-grade treadmill. Variable cone pulley will give more torque at low speed where it's necessary.

I do have a six inch diam. pulley I can put on the saw wheel shaft
(motor is 21/4"dia.) to drop it down a little. |
