Hello,

I purchased an old Oliver lathe a number of years ago, and it came with a DC motor and a controller/converter that lets me adjust the speed. While using it recently, I experienced a slight shock when running the lathe and touching the tailstock screw handle with my right arm. While running, i connected a volt meter to the chromed handle and the outlet box and got a reading of 55 volts. This number drops to 5 volts if I stop the rotation and drops to 0 volts if I turn off the power to the controller/converter. Is this a grounding issue? A few photos have been included.

Thanks,
Steve
