Hi gang, would love your input on this, got a drill press with 1HP motor, unfortunately at the time of purchase I didn't get to test it thoroughly so I'm stuck with it, it is fine for the most part but changing the belt pulley ratio is a big hassle in this model basically. (and indian company with no website as far as I know) , is it possible to keep the belt at a position and just put a VFD and use that to change the speed/torgue?
