    cracked grinding wheel

    I have one of those wet wheel sharpening grinders that has been on the market for many years. Delta sells them, Grizzly does and many others, mine is a Griz. I have had this for about 15 years. Yesterday, I noticed that the large, white, fine, 2"X10" wet wheel is cracked. I don't know how this might have happened as it is not subject to stress or impact. But, it's cracked. Wondering if I should just keep using as is or would it be feasible to drizzle CA into the crack?

    I think CA breaks down in water after a few days, not 100% sure though.

    Frank, after seeing a few “exploding wheel” videos during my tenure as a machinist, I would replace it immediately. Granted, it isn’t spinning as fast as a regular grinding wheel but if & when it does come apart, it isn’t going to simply fall off the arbor, it’s going to go flying. Don’t take that risk.

    I don't think 'flying' or 'exploding' will be a risk. The speed is r-e-a-l-l-l-y s-l-o-w. Mebbe 10 rpm.

    if you only use the side of it and it turns slow, just band the outside of it witha a Stainless steel band if can find it. Like they do mill stones.

    According to Grizzly, it’s 70 RPM, enough to get your attention.

    Worked in machine shop, one did explode.........

    not worth the risk, unless you got a extra glass eye in your pocket, that you wont be able to get to with no fingers.

    If it's the one I'm thinking of, I had the Delta version I got at Lowes. Thought it was a great deal since I only paid about $15 for it on clearance. The wheel cracked in less than a year. I couldn't figure out how to replace the wheel nor find any replacement wheels, so I threw it out!

    By the way Frank, I agree. These turn so slow, I don't think there is any hazard of flying schrapnel.
