For sharpening I have an idea - Arlin Eastman - 12-02-2017
but do not know if it will work. It will have to be with power that could be used on a Worksharp, grinder, or lathe.
Here is the link and the diamond plates he sells goes from 150g to 5000g

See if this is something new we can all use or maybe?

Having next to no experience doing lapidary work I'm fairly certain of this. Used in lapidary applications these discs are used in REAL low rpm ranges. I would never try them in a grinder or non variable speed lathe. They also have to backed up meaning, you would need mdf or such to keep the wheel from deflecting as they are only 1mm thick. The other thing is they are always used with water.

I have 1 of these for carving tools. It runs at 33 RPM. It uses diamond wheels , and a reversible strop wheel, maybe leather. I haven't tried tuning tools on it. I think it would work, but it is slow.

I use diamond slips to freshen edges all the time, no reason to suppose plates would be any different. Grinding is a different animal. Most of us use grinders because they're quick and common.
My SiC wheel is 120, the slips 220. No need to get crazy fine unless you're lapping, rather than freshening.

I have a Foley slow-speed sharpener intended for carbide tools..It uses a 6" diameter sintered diamond plate. I'm betting the diamond coated discs are plated diamond..not sintered.. I doubt they will last long..Better I think to use a copper or tin disc and diamond paste but it must run at slow speed or it will sling the diamond paste off....IOW less than 100rpm.
I also have a Veritas slow-speed sharpener but it is faster than the Foley..I haven't used diamond on it yet. I was hoping someone would sell a flat, sintered Boron Carbide disc with 180 grit like the wheel I have on a bench grinder to go on it.
I was into the lapidary/silversmithing hobby for about three years and many of those lapidary tools can be used in sharpening.
