Bob,
I have had very good luck with the Hitachi brand VFD's. They will give you speed control, as well as inverter capability. I have one on my band saw, I wanted speed control and only had single phase available at the hanger. Bought the VFD and a 3 phase motor, and it works great. I wouldn't do it any other way. just keep in mind, motor HP (I am told) drops as the freq is reduced. Though I have never had a problem with the bandsaw. Cheapest place to find them, Ebay. A place called Drives Warehouse or some variation of that has them listed all the time, new in box. Turned out to be cheapest I could find anywhere.
For what its worth.

Thanks! I'll check it out. I'm shaft-size critical for this
task. Half of the speed changer mechanism mounts directly on
the motor shaft so that feature has bounded my choices to
some degree. Appreciate the heads-up!
