I'd take off the vintage Rube Goldberg (or Heath Robinson for thos on the other side of the globe) original setup and replace it with a single phase PWM driver and DC motor. kbelectronics.net has some with basic controls, just an on/off switch and a speed control knob with safety that requires the knob to be turned to zero before it'll start the motor after power has been off. An e-stop setup is up to the installer. The KBWT-26 list price is $168.00 (For 1HP motor) The KBWT-210 list price is $228.00 (For 2HP motor) Those are bare units, enclosure is up to the installer. They do have ones with enclosures and displays and more controls, also available in rack mount - all extra frippery not needed on a lathe. ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
