Default Pulley-Driven Bench Grinder

I know that this isn't an engine question, but, was wondering if anyone knew where I could find a grinder set-up that attaches to your workbench and is pulley-driven from an electric motor??? My grandfather had one of these, basically - the way I remember it, it had a horizontal shaft that held two grind stones and a pulley. The frame was a flattened U-shape with bearings for the shaft. The pulley was connnected to an electric motor by a V-belt. The reason I'm looking for this is that I want to set-up a grinding wheel that I can regulate the speed by changing the pulley sizes, most of the bench grinders on sale today turn way to fast for what I need. If anyone has any ideas about building one, please respond also. Thanks.

I have seen those in farm/home stores, I think Sears still has one in the catalog. They are real handy for polishing as the motor is not in the center taking up all the room for getting in the tight spots. When I was a kid we had one with the motor under the table, with a step pulley on the motor. The motor was mounted on a sliding shaft and you could move it sidways and jump the belt to any of 4 steps. We used grinding wheels-wire wheels-Buffing wheels. The wheels stuck out in the open and you could really work around them. It was a bit noisy, Quite ugly, but very practical. Al

I have one of those I use all the time. Put it on a stand when I was in Grade school and that was a long time ago... Much better than the new Chinese ones that turn too fast and vibrate You might try Farm auctions also. I like about 1500 to 1700 RPM, about half the speed of the new ones

Remember that the thread on the left end of the shaft is left handed.

Hi Drew, I bought this one in mid 50's at Montgomery Wards, has ball bearings and use regular. The one from box is nos from yard sale, Dayton Electric Co. Chicago. Right is double shaft Dayton with diamond wheel, motor in back has wire brush.

These tools make lots of mess, so pull out wooden handles and roll outside. Good Hunting Ralph in NC

My Dad still uses his grinder of this type (sears) and also has a simmular Mini Drill Press. He told me once that it was an old jewelers drill that he got when it was no longer accurate enough for the local jeweler. It has a V-belt the goes around the pulley on the chuck shaft, back around 2 more pulleys on a small horizontal shaft mounted to the back of the press, then down to the motor mounted under the bench (makes a looped "L" shape). It's not over 1 1/2 foot tall (actual drill press height), and is great for small stuff.
