A better pic for you, the readers.
Interesting how the shrouds appear to be part of the motor housing.
I decided to randomly search for grinders, here's one not WI but MI, price is right, and appears heavy-duty.
Has a wire wheel and buffer wheel on it right now. Runs good nice powerful grinder / buffer. Runs on 110v power.

Has a wire wheel and buffer wheel on it right now. Runs good nice powerful grinder / buffer. Runs on 110v power.
As an added bonus, make the trip on a Wednesday afternoon, and after picking it up, head south on US-131 past Martin (MI) Dragway, and visit scenic Hickory Corners where you can enjoy one of the nation's best Auto Museums, the Gilmore.
Wednesday Night Cruise-Ins at the Gilmore Car Museum have become an annual summer tradition!

I recommend a stop at Ned's on Gull Lake, about 10 minutes away. A good restaurant.

On Saturdays and Sundays, head to Galesburg Speedway, another ~20 minutes from Ned's, by I-94, in Galesburg-Agusta MI.
Schedule of Events this year at The Burg. Races are on Sat and Sun Night's, fun for the family. Located on I-94 between Battle Creek and Kalamazoo Michigan.

You can see the world's fastest plane a short distance from Galesburg Speedway, at Air Zoo (that would be the SR-71, and this one is a two-seater!). If it takes you 20 minutes from Galesburg Speedway to Air Zoo, you were dawdling and sight-seeing.
The Air Zoo, located in Kalamazoo, MI, offers an exciting educational experience like no other. Featuring more than 100 air and space artifacts, Air Zoo also includes multiple interactive and educational exhibits such as full-motion flight simulators and amusement park rides. Buy Air Zoo tickets...
