I got this grinder for free when I bought my 13"x40" South Bend metal lathe from a private sale in Connecticut a couple years ago. An old machinist passed away and the lathe and grinder were in his basement. Lucky for me the basement had ground access right into their garage, making the lathe removal a simple one. This grinder is a 3ph, 1/2hp grinder, complete with Stanley no. 600 eye shields. The shields take 2ea #94 automotive type light bulbs, and will require a small transformer to deliver the 12v they require. I am looking for a pedestal stand for it, and it runs great. The base of the grinder is unusually large, 12" front to back x 10" wide.

I finished work on this grinder some time ago. I ended up tearing it down, new bearings and painted it with Rustoleum hammered paint. I really like the look it gave on this small project. I ended up replacing the eyeshields that came with the grinder due to deteriorated wiring. I couldn't so much as move the wires without crumbling the insulation. Not wanting to start a fire, I decided to buy new eyeshields from McMaster Carr. By far the most expensive part of this rebuild, but I think well worth it. I did add a 3 pole toggle switch to the grinder, and wired the lights in series so that the 240v power could power the 120v bulbs. This is a good way to avoid a transformer in situations like this. A flip of the switch turns on both the grinder and lights simultaneously. Runs smooth and quiet.
