Checking stone for flatness?

Sandpaper on a kitchen worktop will achieve the same at a much lower price. And yes: it does not have to be 110% flat.

A hundred and ten percent flat?

The flatness of your stone does not have to be within NASA tolerances. The pencil grid method has served us well. I think if you were to use a straight edge test, you would end up chasing your tail, and eating up too much of your stone.

I never really tried to use mine on anything other than the Norton synthetics. Once I got that rubber that came with my Chosera 1K, that's all that I used on the Nortons. It worked so well that I didn't need the flattener any more.

Yeah, it certainly works a treat on the Chosera. Think I will try it on my Norton hones as well for a while!

Loose grit on a cookie sheet will get flat in a few minutes with loose 60 grit Silicon Carbide and an assortment up to 500 grit, for $15.

For large stones, you can get large commercial cookie sheets or a large marble tile or slab from Habitat for Humanity and make a dam with folded Duct Tape. It will contain the slurry.

I have a 20X18 in marble slab, I paid $2 for.

No need to trash a diamond plate, Arks will pull out diamonds.

I've been wanting to get one of those, or the one made by Norton for my synthetics.
