I have a set of Shapton wet stones and I’m interested in knowing what others use to true and flatten their wet stones. I know Norton and a few others make stones specifically for this, but after reading some reviews, it seems many have been received that were not flat themselves. I guess diamond plate is one option and the other is a cast iron lapping plate that requires powered abrasive. Are there any other options? I’d like to hear about what others have been using successfully.

Drywall and floor sanding screens work well
for water stones.

Atoma 400g. The one I have is just big enough but works well.

Hmmm? I have some floor screens. What grit? So you adhere it to a piece of drywall and then use that to flatten the stone?

I have some used screens from floor sanding
jobs I use. I just lay the screen on a flat
surface and the clay from the stone falls
through the holes. I don’t think grit matters
that much as a little usage of the stone and
the sanding marks disappear. I don’t know
about other brands of water stones but my
King and Norton stones are quite soft.

I use this. I no longer have Shapton stones, which it worked great on. It is equally as good with Japanese stones, which I use it for now.

Loren I can see how they would cut the stone, but you feel confident enough that the process creates a true surface on the stones?

Yup I saw that one and the price LOL I guess it’s a one time purchase as it will probably last many years. But it is pricey for the purpose.

Fridge I searched your Atoma. It’s a diamond stone. I have a couple of cheaper diamond plates. Maybe I’ll give them a try. I no longer use them for sharpening.

Bill, yes it is pricey, no doubt about that. Mine is seven years old now and stills works the same way as new. Quick math shows a cost of $18.95 per year over twenty years. It is absolutely worth the money in my opinion. I never question whether my stones are flat or not; they always are.

Having said (written) that, there are other methods like the ones suggested above. I happened to have a couple extra bucks in my pocket at the time and bought it. But other methods can give good results as well.

DMT makes a line of diamond stones that are suitable for flattening water stones as well as their primary purpose.

I also second or third the diamond on glass plate for your Shapton set.They are not ordinary water stones more like a ceramic.The diamond on glass will not only cut them flat quickly it will leave a very nice surface.
It’s a bit expensive,Shapton also has a Diamond reference lapping plate that’s bronze.It will set you back about 500.
But it’s has two sides the glass only has one.
I have both and i like them.

I never invested much in my stones, they are quite soft, so when some flattening is required I use a flat marble or a thick piece of glass with some good sandpaper over it and do what i can :D
