Convert this motor to a buffer?

I found this old Dayton motor at the flea market today. Do you think it is possible to convert it to a buffer?

The problem I can see is that the shaft on it smooth with a flattened part to use a set screw with. It isn't threaded like a grinder or buffer would be

The guy said he thought it was off an old A/C unit.

Here are some pictures.

1/2 HP is a bit low for buffing, even with a good full rated motor. (Lots of drag when buffing)

You CAN get a threaded arbor that slip on with 2 setscrews, but get a good one, and make sure the set screws stay tight...

I wouldn't, go get a cheap bench grinder and put buffing wheels on it if you want a low cost buffer.

To buff at 1750 RPM, you'll need large diameter buffs. (ie 8-10") Like Outlaw says, that motor is a bit wimpy.

If you use std 6" buffs you likely won't get the SFM needed to cut , color and polish.

You should also use a totally enclosed motor for buffing.

It'd work marginally well if you got an arbor and ramped up the speed by using a larger pulley on the motor driving the smaller one on the arbor, like this guy did.

Seller was right, a shaded pole motor like that usually is employed to drive a blower, but be advised sometimes they required cooling air to be flowing over them to stay below thermal cutout.

OK thanks a lot guys. I think I'll just sell it to someone who needs it for their swamp cooler or whatever

Is there an easy way to hook it up to see if it works? (Seller said that it works but I'd like to verify that before reselling if possible)

There is a wiring diagram on the sticker, see the 2nd picture you posted. Where it says "line" that is where the incoming AC power goes. Green is for the ground, which is the green wire and round prong on the end of the standard 3 prong cord. Specifically the studs and nuts are where the power cord attaches, one wire to each stud. FYI, it is an 115v only motor.

Thank you! I was confused when one said "line" and the other said "ungrounded line". Got it all hooked up and it works fine

I think I might try it out with an arbor adapter and some paper wheels to sharpen knives. I only spent $10 for the motor so I won't feel too bad if it ends up letting out the magic smoke!
