He's afraid the stone is going to blow up lol.
I do need to check the thing out for visual cracks.
That is a good idea, we have a lot of junk to practice on.
He'll let me ill just tell him I want to make him more money
What kind of grinder is it? The one I learned on was a Van Norman 477. I know there are way more "modern" machines now, but it was a nice old grinder and did a really good job. That old guy kept it in tip top condition. There were digital dial attachments available for it even back then (about 1980-81) but he swore he'd never get them and he never did. He said keeping "fresh" on reading analog dials and mics made a better machinist out of you and that the digital stuff made you lazy. lol
