OK....so, from what I understand, that ANSI Grit information is for sandpapers, belts and wheels, and is in fact not used for waterstones. In your post, it says that the Norton 4k/8k uses the Japanese system...so a Norton 8K should be the same as a Japanese 8K stone.
I tried to find some corroboration.
If we look at THIS link, then the Listed US 8K is at 3 microns, the same as the Japanese waterstones.
Then, in this excellent post, we find that that the 8K Norton stone, at 3 Microns, is the same as the NEW JIS 4k.The new JIS 6k is 2 Microns--finer than the Norton 8K at 3 microns.
And then, THIS link shows us that a Japanese watersone at 8K is 1.2 microns. I found similar information on other sites.
SOOOOOO...Japanese stones at 8k are either 1.2 micron or 3 micron, and Norton stones use the Japanese numbering system, and the US system is for paper, belts and wheels.
That clear things up for you? Cause it didn't for me...
**EDIT**Anyway, for the OP...If you have Japanese waterstones up to 8K, then I would imagine you're ok.Last edited by JimR; 05-19-2009 at 03:19 AM.
