took a pawn shop chance on this one a couple weeks back. it looked rough and needed wheels but had a new cord. hell a cord is 10 bucks.
it is a 6 inch ram. i don't believe this is a top shelf ginder as when i took it apart there are no bearings in it. it has oil-lite bushings about 1 1/4 inches wide with felt seals on each side of it. it ran a little loud so i pulled the bushings. put a little high temp grease on them and oiled the felt. put it back together and slapped a rattle can paint job on it. it runs pretty darn smooth and quiet now.
it looks weird but it is pretty usable despite the odd shape and design.

I had one but I ditched it because of the bronze bushings.

Judging my the Chicago address, that thing must be at least 60 years old. It's in pretty good shape for being such an old-timer. I wouldn't let the fact that it doesn't have BBs be a worry. Oil-Lite bushes were at one time the norm for non-industrial equipment.

What high temp grease did you use SK?
-
I think its "Cool Looking", should have listed it in the vintage electric tools. 8)

nothing wrong with oil-lite bushings. if maintained the are very good and are actually pretty durable. the oil-lite actually "holds" lubricant in its porous makeup. many turning lathes have and equipment use it and with proper care it last a lifetime. sadly, with neglect it doesn't hold up. i am positive this ram grinder saw little real use but if it needed bushings i know it would be scrap iron. i was surprised that under all of that iron the windings and armature were rather small. it does have another interesting feature. unlike most grinders i t has a fan that pulls air from under the back of one side of the grinder, through a fan and the windings and out the other side of the back of the ginder.

Good move buying that grinder. I would have done the same for the right money.

The bushings in mine were worn out and made it impossible to balance a grinding wheel, the only thing I could put on it was wire wheels.

You can buy bushings at McMaster Carr if the need arises.

i would be surprised if they had these. the bushings slide into the housing on each side and are held in place by a collar. they actually have a round globe shape with a rim on each side. almost like a self centering bearing. like i said before this thing is an odd duck! :))

Looks like a solid grinder!

Nice find Farmer.
I am sure it would have followed me home - even though it's not a Block grinder.

That was worth $15 and as far as the bushings, since when are they a problem when you have a lathe? ;D
-
Very cool!! As far as Oil-lite bushings, we use them on some of the manufacturing machines at work.

SK,
That's a great old grinder. And, it's got some kick-ass tool rests-- stout & well designed.
One of my grinders is chineeezzz cheepo. The grinder itself is ok, but the tool rests are worthless; flimsy, too small, and not even square to the stones.

an old thread popped up at the jornal. looks like this same grinder was also tagged as a cummins. i wonder who actually made it?
