electric motor shaft question.

[Dave]

Do any of you know if there is an adapter available that I can install on the shaft that would enable me to put a buffing wheel or grindstone on the motor? All I can do now is put a pulley wheel on. Thanks

Good link from other poster. Proly also MSC, McMaster-Carr, Graingers, mebbe Sears.

You might find, tho, that 6" grinders are so cheap, and occasionally on sale, that just buying a grinder is ultimately the better choice--esp. if you subscribe to wheel covers, tool rests, safety glass, water cup, etc. Plus, 6" grinders are double ended, so you can put a buffer on one side, and grinding wheel on the other. No sale: $29-$39. Sale: $19. Harbor Freight, Sears, HD, etc.

If you insist on using your motor, they make a stand-alone double sided wheel mount, which has a center pulley and would be driven by your motor/pulley/belt. I plucked one of these out of a dumpster, and actually use it! In addition to my six other grinders/sanders. :) Uses more real estate, tho.

You may want to post on rec.crafts.metalworking for more than you ever wanted to know about grinding setups. :)

Thanks Oren for your help. I will print a picture and check out locally first.

Save the ink..

Know the dia/size of the shaft/adaptor you need.

Just as important would be the correct RPM for the device you buy.

That's what I have. I got a General brand one of what you said at one of the rural auctions, and a big motor from somewhere, mounted on a piece of wood.

I think it turns about 1 to 2 times as fast as the motor does and works well for a grind stone and a wire wheel.

True. Fairly hard to adjust the belt tension right, but I only have to do that every 3 years or less. It may also be an advantage that if something jams the wheel, the belt slips. Not sure what a direct drive would do in that situation.

It's called an "Arbor" they come in different shaft sizes. The better ones cost about 15 bucks and can be had from the folks selling home made windmill parts -less runout than the ones on a blister pack in the hardware.
