Hey girls and boys, I need some advice on a cracked sharpening wheel on my Delta wet/dry model 23-700. It seems the 2”x10” dia. aluminum oxide stone has developed a radial crack all the way to the center. I’m not sure how or why it happened. This stone is the slow moving wet stone. Now when I go to put an edge on anything it’s like jumping the creek on every revolution. Could this be repaired, or is it a big round bench stone now? And if it can, how would I go about doing it? Thanks in advance for any and all advice.

It is probably a goner.

I never use anything that spins that’s broken or cracked . It may have been defective from day one hard to tell.

Throw it away.
Extremely dangerous to use.

Having worked in a grinding shop for 15 years I can tell you you need to get it off your machine. Its a disaster waiting to happen.

Bagtown said it right, throw it away. I know of an incident in a car dealership where a cracked stone embedded itself in a ceiling. Had it broken at the right nano second, it likely would have killed the operator. Everyone above is correct.

Thanks guys, I just thought since it runs at such a slow speed that maybe it could be saved but it doesn’t sharpen right anyway. Do I have to go to Delta for a new one? Or does anyone know of an after market link?

So come to find out the 10”x2” al.ox wet wheel on my Delta 23-700 grinder is obsolete at Delta. Need help finding a replacement or it’s on to buying a new sharpening system. Ouch!!!!!!

If your shop aint heated and it got below freezing it could have cracked it.

Every answer here is the right one but I would keep it and use it laying on its side to do hand sharpening. Call me cheep! Don’t even chance it one time.
All you should need is the arbor size to get another wheel.

The wheel for the grizzly slow speed ten inch wheel should fit it.

Might want to take a look at the Norton line of abrasive stones. They should have a current replacement
