I am searching for what I believe is called an arbor grinder – a pulley-driven arbor, driving two grinding wheels, all supported by a U-shaped cast iron frame. The grinder is powered by a separate motor with a v-belt. (I apologize for the bad description; if you’ve seen one, you know what I am describing.) All of this can easily fit on a bench. I wouldn’t be surprised if they made these 100 years ago. Although these are somewhat dangerous, I like the fact that I can easily change to a slow speed simply by moving the drive belt between pulleys. I used one years ago in my father’s shop and liked the slower speed and open access to the wheels.
I would appreciate any suggestions where to find one (w/o motor).
Thanks.

Lee valley has what your looking for.
Thank you. It looks like a modern version of an old design, that will do the trick.
You can also put an arbor directly onto a motor for about $5 from Grainger, left or right hand thread, 1/2 or 5/8 motor shaft. 1800 rpm is half-speed compared to normal grinders. I use one for wire wheels and polishing.
Be seeing you...

Dave,
Thanks for the link to Prairie Tool. Interesting catalog with a great selection of grinders and mandrels. Great prices, too. Maybe this should be in a new thread, but I would be interested in hearing about your wet grinder. Which model? What do you like/dislike about it? I'm looking to get one mainly for grinding the main bevel on chisels and plane irons.
Rick
