Hi all,

There is an item called an arbor attachment for electric motors.  McMaster
catalog page 2523.

The item description is as follows;
Convert your bench-mount motor into a grinder-buffer. Fit this attachment
onto the motor shaft and then mount wire wheel brushes, grinding wheels, and
more. Shaft thread is right hand. Flanges and hex nut are included.

They support shaft diameters from 1/4" to 5/8" and the most expensive one is
only $4.50.

Here is the one you may be interested in;
Item 43555A25
Arbor Attachment for Electric Motors Fits 5/8" Shaft Dia, 1/2"-20 Wheel
Arbor Size
In stock at $4.50 Each

I have never used one of these, but they look promising.

Remember to make an enclosure for the rotary gaps.

Cheers,
