Geeze I'm sorry I don't think Darry would be straddling a 3 foot diameter grinding wheel when there's a "Busting Force" that's probably coming.
The closest Ive come to that was once while working on a Blanchard grinder the power went out during a cut and the electro magnet threw a lower die shoe off the table into the metal guards ripping them off the machine and exploding the wheel segments. Was never more scared in my life. I was also soaked with rancid coolant.
Good Times Har!!!
