Thread: Charnley forest slurry stone

Hello gentlemen,

I recently bought a CF and I would like to use slurry techniques on it. CF (as eschers, J-nat...) are hard stones, then it is possible to use naguras as we do with japanese to form some slurry wich comes from the nagura stone (not form the hard finishing stone) but if we want to form it from the CF (tomo nagura concept) what can we use?
I don't have a little CF stone to do it and won't cut my CF for it. I don't even know if it is correct to use a bout of CF to release slurry. I don't like the idea of using a DMT (a diamond on the CF when final polishing is performed and all work can be ruined)

How may questions, how many doubts...

Anyone has experience on it? Any idea?

Thank you

you don't have to use slurry while you sharpen on cf.
if you like to experiment that is different.
you can use anything you like.
start paste==========end up dmt.

I would think both the bout and the larger stone would be very hard and take a while to slurry. I am sure you can use soft jnat nagura stones on it though. Have you tried oil on the cf? From what I hear that's the edge you'd like to have from that stone.

Never tried with oil. I would like but it seems too "sticky"
I tried the naguras but slurry is different because it allways come from the nagura. With a tomo nagura the slurry comes from the CF (the same for the DMT option). I suppose is the same principle as when we use a bout of escher on a bigger escher... but I've never seen bouts of CF....

if you want to get final edge out of your cf
you have to use oil without slurry.
this is how it has been used forever for finishing purposes.

I'm firmly in the "start with a very light slurry and dilute to water" camp. My Charnley is quiet, hard, and smooth, just like a cheerleader I knew in Gainesville back in the 80's named Enid, and I found that, like Enid, it needs a bit of self-love to get started. After my Coti I rub a Charnley SS on it a few times (again, like Enid) and find that it responds with a bit of noise and a smooth edge, once again, like Enid. After I hose down the Charnley, like I did Enid, it finishes off smooth as silk (must I say it again?)

That's all I've got to say.
