Thread: Checking stone for flatness?

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.

Yep I Got My First Stones Flat AllRight!!!!!!!!!!!!! Washed Them Right Down The Drain!!!!!!!!!!!!!!!!!! But Hey They Were Flat!!!!!!!!!!!!Didnt Do That Again!!!!!!!!!!!!!!!!!Ty
