If it runs true it might be good for a fixed-point carving setup. Chuck instead of pulley to hold diamond bits and burrs.

Looked like it had a pulley on the end of the shaft. A keyless chuck on the shaft would let you set up for carving stones. They call that a fixed-point setup as opposed to a handpiece. Lets you hold the workpiece with both hands so it's a lot easier than holding stone in one hand and tool in the other.

Hope that helps.

That's probably the motor from one of the old fashioned dental drills which were run with round belts. There is probably a connection on it somewhere to hook up a speed control pedal. If you can find a pedal that will work with it, there are adapters made to fit the motor shaft which would allow you to connect a flex shaft and hand piece to it. It would make a great little carving machine.

As for the pedal speed control: Since it has a standard three prong plug it probably plugged into a foot peddle that was the speed control. So no extra connection to the motor required.
I have a similar motor that I put a small buffing wheel on. The chuck sounds like the way to go and you can use it for a lot of things.

Just now looked at the size of that unit, and where the switch and cord are, and it could be a good height for holding a stone against whatever burr you'd have in your chuck.

Some plastic to shield it from the water drip you'd want to have above the burr and it should be safe. With the right bits, burrs, grinding drums, and little brushes and buffs you really could do a lot.

I have a couple of those left over from an industrial experiment.  It is 110 ac only.  Not speed controlled.  Not water protected.  Very high quality precision bearings and high speed arbor.  If you use it for bits, be sure to keep them small as high speed can cause larger diameters to become dangerous.

I just got the motor today.
Very Cool...115V, fully reversible direction by toggle switch, and variable speed with my ebay electronic variable speed control unit.

Please make sure to plug it into a GFI if you're going to use it as a point-carver, as I enjoy reading your posts! I have one of these myself and haven't done anything with it yet.
