Hello,
The Edge Pro sharpener is very good but,
they provide waterstones only up to 1200 grit and a 3000grit polish tape.
What happens if I wan't to use a 6000, 12000 or higher grit?
Where can I find that extra stones that could fit in the sharpener?

I have a 6000grit big stone but I'd like it to use some kind of device to sharpen keeping the proper angle, and it can't used with the Edge Pro.
 
While the grit sizes for EP are supposed to be standard US grit sizes, they finish higher than one would expect. A 600 EP stone seems to cut and finish about that of a 2000 JIS water stone. Comparing JIS and US grits is difficult at best.

A 600 grit EP finish is pretty dang fine to my thinking.

Edge Pro stones and tapes available are (roughly and a best guess)
120 stone = 200-220 JIS (116µ??)
220MF stone = 800 -1000 JIS (60µ??)
320 stone = 1200-1400 JIS (40µ??)
600 Stone = 2000 JIS (30µ??)
1000 tape = 3000-4000 JIS (12µ)
3000 tape = 7000-8000 JIS (3µ)
6000 tape = 10000-12000 JIS (1µ)*
10000 tape = 25000-30000 JIS (0.5µ)*

(Available from EdgePro but not listed on their site. Also all tapes are available from other sources)

Other stones are available but I haven't found any that go past 600 grit. See
Congress Tools

You could always get Shapton or Norton water stones and have them cut to fit. I'm still waiting for someone to do that.
 
thanks for that info. Mine is 6000 Minosharp. I don't know if it follows the american or japanese system.
 
The Minosharp likely follows the JIS.

Even with the various conversion rates, the 600 is finer than its grit size implies.

That said, you can always get some aluminum oxide or silicon carbide lapping film from 3M or silicon carbide and chromium oxide sandpaper from HandAmerican and use them with your EdgePro tape blank. 3M's lapping film goes as small as 0.05 microns which is twice as fine as 200,000 grit American and Hand American's chromium oxide sandpaper is 60,000 grit (0.5 microns).

QuietOneD,

What are you trying to say? ;) Did She Who Must Be Obeyed of NWT give you permission to order custom Shapton Shapables from Harrelson?
 
Just out of curiosity... What is the advantage of going with an ultrafine grit versus stropping, which tends to be more forgiving about the angle? Are there advantages?

I just bought an Edgepro (it arrived yesterday), so this is all very relevant to me. Thanks!

LORD no, if she even knew I was thinking of buying another set of Professionals just to cut pieces off for the EdgePro...... You're hear the scream there from here! I never thought of getting shapables sizes aren't quite right.

Actually the main thing (other than cost) holding me back from getting a couple Professionals to cut on is that I have no clue where I'd get them cut. I still think 5K,8k, and 15K Shapton cut for the EP would be interesting to try. (wouldn't a 30K be different?)

Someone really should try this, it's not likely to be me any time soon.
 
The regular Shapeables are too small, but a custom order of 1x6x5/32 in 2000, 5000, 8000, and 15000 with, maybe, 20 stones apiece might be tempting to them.

Since Shapton stones are resin and abrasive, I wonder if it'd be cost effective to get some molds, some epoxy, and 0.7micron BC and 0.3micron Linde A and make homemade 16,000 and 50,000 grit wannabe Shaptons.
 
Hmmmmm... But you really do need 30K in there too. (Just for giggles and the smile) Ok who has a contact at Shapton or knows Harrelson personally?

I actually thought of doing just that. Then I found out they do it under massive pressure and heat as well. I did try BC in reconstituted flower pot clay, don't ask, it was BAD.
