    My father picked up a new stone at Home Depot, put on bench grinder, and fired up, no problem. Went to go use the grinder again to sharpen soap stone, and fucking thing exploded. My father was on the other disk, but had he had been in front of the one that let go, could have been seriously hurt. The only saving grace for both of us, is that the disintegrating wheel jammed against the drill bit sharpener pad, and jammed. Slightly cracked the housing of the grinder, but it still works. He's pissed, Home Depot will be getting an ear full tomorrow... hahahaha

    Funny thing is it was made in India. Does no one make a quality product anymore? Grinder rated at 3200 rpms and stone wheel rated at 4500... me thinks it was defective or had a crack not visible. Should have tapped the stone with a piece of steel to see what sound it made, but didn't think of doing it...

    Always ring a wheel before mounting it will let ou know if there is an imperfection. Best to buy a Norton or CGW i.e. name brand. I think most of the marts sell cheap import wheels. Welding supply store would probably be a good place to look.

    Yep, should have checked the sound it made. Since it was on a Sunday, no "commercial" welding, etc. supply stores open...
