Base doesn't match any that I've identified. Guards don't either.
Recognize this bench grinder?

Looks like an original Grainger. Originally that was a grinder manufacturing company before the name was taken for industrial distribution. Every bit as well made as Baldor.

Measure what size wheel would fit with normal clearance inside the wheel guards.
this, or take off the guard, measure from the center of the shaft to the guard , double that ( minus a bit ) & you have your size

Does it come with the stand? How much are they asking?
This may be a situation where you buy first and ask questions later...

Any clues on the other Grainger? I see WW Grainger founded in 1927, so tried looking prior, only found pumps in Louisville KY. City, era, anything to help the searching?
By golly,I think we have a winner.

VFD on old Walker Turner grinder/buffer.
I found an old 1HP Walker Turner 10" grinder. It's 220 V, three phase, AC motor. It's missing the switch and one wheel guard but I think I'd like to get it and set it up for polishing and wire wheeling and keep my Baldor 7" for sharpening. At any rate, getting 220V to my shop seems to be...

Bring a zip cord. Plug on one end, bare ends, or clips on the other. Wire nuts if you go the first path. Tape for the 2nd if too close for comfort.
Or an extension cord, carefully stuff the bare ends into the female end

If the shop has 3P power, you should just need a 3P breaker in the breaker box. Wire the existing cord to that and see if it hums.

Sir, this is Garage Journal....You need two more!
I bought it. Still don't know if it'll run. Tried to measure across each winding but the numbers were bouncing all over and bumping the switch made it worse, so I'll find out now when I get it home. It was in the back of his dad's shop, some big business that dealt with machinery, when they cleaned the place out. Wasn't hooked up, so decent chance it won't run. Also don't know if it's 240 or 480. But since it's unknown condition and the readings weren't very deterministic, I took it and the stand home for $25.

Sounds like a wonky switch to me. 3P motors don't have a starter switch or cap, so pretty easy to compare the resistance across all the winding. Also check between each winding and ground and from winding to winding.
If the data plates have been painted over, it looks like several others here have the same motor.
BTW: YOU ****! The stand alone--not great but a stand--is worth more in scrap than that!

The dataplate is missing. I don't know if they made multiple variations of this grinder, so if they didn't then it should be pretty easy to deal with. But if they made multiple variations such as different voltages then it's kind of a guessing game.
Looks like it's a GR100 and so far I've only found 240/3 so I may be okay there. I'll try to hook it up tomorrow and see what happens
