I found a couple dozen or so grinding wheels in various boxes and bins. Judging by the labels on them, would guess that they are 40+ years old. If there are no visible chips or fractures, are they safe to use? I know they spent at least 3 years in unheated shelter during Minnesota winters, but don’t know if that affects anything!

Edit: I forgot to mention that I have a hearing disability. I am aware of the “ring test” but it’s not an option for me, hence asking for advice.

Haha guess that’s an option… is the potential shattering something that will happen once it gets to speed, or can it happen anytime in the future? And what’s the safest angle to stand at if it DOES explode?!

dandresow: Thanks. Haven't done anything with rocks for years. Just fixed an older HP 18 inch and dug out a 10 inch and 18in Lortone and I have a couple of trim saws and need to make something to cab with. We stay broke and I only have enough to put oil in 1 Dec 1, 2024 16:49:20 GMT -5 *
