Horror story, do not read if you are squeamish.
My bro-in-law's next door neighbor built his own grinder with a motor he had laying around and some wheels he bought at a garage sale. He turned it on to show his wife and the wheel exploded and hit her in the face. She lost half of her jaw and one eye.
It's been 10 years. They're still married. I can't imagine how he must feel.
Never exceed the RPMs listed on the label of the wheel.
