Thanks for all the feedback guys. I guess I don’t have the three phase figured out, then. The guy that gave me the info on the VFD has one on shelf sander that he made. It works great on his but he uses it only as a speed control on his sander. I have two motors. One is on the spindle and one on the table feed. So I guess I can’t use the VFD according to feets. I’ll check American rotary phase converter. My spindle motor is only 1.5 up. As far as the collet. I have one tool that came with it. It is a drill Chuck. I’ll post a picture of it and the spindle. It looks to be just a 1/2” straight shaft. I’m out of my element her for sure. Any help is appreciated.
