A Powermatic 65 cabinet saw followed me home the other day. The rebuild is on the docket for this fall / winter (after i finish up the "summer" projects i'm not quite done with). I'm pretty excited about it. The contractor saw i've been using is a great tool, and i've done a lot of good work with it, but an old Powermatic cabinet saw was impossible to leave be.
At any rate, it's got a 3 phase motor on it. Cheapskate bottom feeder that i am, i'm looking at my options for firing it up in my basement shop - steroid fed hampsters on a wheel, swap the motor for a single phase motor, or use a variable frequency drive (vfd). The motor is a C-frame, so that makes finding an old (read "cheap") replacement that i can rebuild and attach would require a stroke of good luck. Hampster roid rage is nothing i want to deal with, and phase converters have some serious downsides. So, i'm looking at getting a vfd to drive the 3 phase motor on single phase. This would be a lot cheaper than buying a new replacement motor.
My hangup is that i've never used one before. What are the downsides? Anyone have an opinion? A 2hp vfd with phase conversion will run $144. That's about $200 less than a new replacement motor.
Thanks in advance.
