Picked up this well abused Pedestal Grinder at a scrap metal dealer here in the St. Louis area. I was initially hesitant to buy it since it was a 3 phase machine, but the impulse purchase won out. No water cups came with the machine but I am glad it did. After a total tear-down, paint strip and rebuild, I purchased a VFD to run it off of my 220V single phase supply. It turned out to be an extremely smooth running motor. I routed the 115V lights through one contact of the switch and the remote run signal to the VFD though a second contact of the on/off switch. I also installed a potentiometer on the front of the grinder base to remotely control the RPM's of the motor as needed for specific grinding jobs. This is a great benefit of using a VFD on a 3 phase machine.

The most trouble I had was re-doing the motor placard, the original one could barely be read and all of the wiring info was gone.
I had to cut a new one out of aluminum and apply a decal that I created based on extensive research and graphics work on the computer. I saved the original placard for whoever one day may inherit this machine. I was able to remove all the old paint covering the serial number placard and get it back to almost like new.
