I completely agree with Cliff. The charts he mentioned are pretty good. But do take the grit ratings with a grain of salt sometimes, they’re not always accurate. And different abrasives work differently, so the grit ratings are not the only thing you should look at. Clay will post new pics of the scratch patterns the WE stones produce in some time. (Won’t you, Clay? ) That should be the most accurate we can get.
I’m working on it a little each day. The first thing is to trying to determine the best, most reproducible setup i.e. which magnification etc… What I really want to do is image the stone and corresponding scratch pattern for each grit.
