I don’t know what they are but I do know that some of those types of oil stones will turn a 220 Dmt into a worthless piece of plastic.
If you really need them flat find a flat cinder block to get you most of the way.
Gook luck and nice find.

I spent a dollar on a cinder block and tried to flatten the stones. This seems very much like a losing battle. I wonder how many years it took the previous owner to dish the stone. Thanks for your reply.

I’d think a DMT Dia-Flat would work. But those are $150+

Those stones are probably silicon carbide. That’s
the same stuff gray grinding wheels are made of.
It’s very tough and hard-wearing. They can
allegedly be flattened with silicon carbide powder
lubricated on a piece of plate glass. I doubt
however it is worth the investment. The stones
are typically not very expensive.

You can get coarse Japan water stones made
of silicon carbide in a soft clay binder. I’ve
never used one but I presume they cut pretty
fast.

Have your say...
