Thread: C12K slurry

What should C12K slurry look like? I use my slurry stone on it and it's barely visible. Rub harder? Longer? (that didn't sound right). Or, is C12K slurry not milky like coticule slurry?

I've had little luck with a slurry stone on the C12K as well. The best thing that Imjve found to create slurry on it is the Norton flattening stone. It leaves a light grey, clay like slurry that cuts much quicker than water alone.

I bet you really don't want to hear my answer

Just like the Coticule, not all PHIG's are created the same, some give of a darker Gray weak sorta grainy slurry, others give off a Gray smooth slurry, and mine gives off an almost white silky slurry ... It took me 4 PHIGs before I kept this one As we always say "A natural stone is by its very nature inconsistent from to another"...

ps: I use a DMT 325 to raise the slurry...

The slurry is way different.
Slurry tends to speed up a hone... I am not sure
that is what you want with the Ch12+/-K hone anyhow.

As a finisher what tricks help it finish better.
My guess is just to rub the rock to clean the
surface and call it good. The rough surface
from the Norton flattening stone might get in
the way of the finishing action. A rubbing
stone should calm down the surface and
leave a light slurry. If a slurry is important
try to not wash it down the drain when it
is so hard to generate.

A Norton nagura would shed grit and make the
Ch12+/-K rock hone faster. Try one they
are inexpensive.

Have you tried it like that ? No Good ???
I'm thinking that may be perfect for the last 10 -15 strokes but of course it could depend on the previous stone used.
Mind you I used to use a 3 figure stroke count when I owned one but then I heard some guy say "less is more"

rickboone,

IIRC quite a number of SRP members recommend using a credit card sized DMT 325 (or other similarly sized diamond hone) for raising slurry on the PHIG '12k'.

Have fun !

Best regards

Beat me to it!

This is what I use on my Chinese hone: 3-1/4'' x 2'' Wallet-Sized Diamond Sharpening Stone - Rockler Woodworking Tools
I think I have the "extra fine" one.

The little wallet size diamond hones are a bargain.
They are big enough that the razor can see a surface
that is flat enough.

Lapping on 3M paper makes it easy to identify
high spots to worry down when making a slurry
and keep the bulk of the hone flat.

As hard as my PHUG is any slurry stone could be
used within limits to change the character.

My current PHUG activity is to find out how
to make it finish best. I have man made hones
that remove steel more than fast enough so
I am concentrating my tinkering on finishing
and polishing.

PHUG PeoplesHoneUncertainGrit -- sort of
sounds like a small dog... Some love them.

Hey, Rick.

I've used a Norton synthetic ruby stone, but have also used DMT, Atoma. Slurry is light milky gray.

Oz, less is more on a c12k? Wow. I'm still in the triple digit stroke counts. They're so slow I don't see how that would work, but you've done this enough to know. 'Really curious how you make few strokes so effective.

You do need to rub it vigorously, It's not like a Coticule, It's not going to give up slurry easily, but they do. Those are some hard stones compared to Coti's. You think the C12k is bad, You should try raising slurry on a J nat, especially a Shoubudani...What you can do, is use the slurry stone on it edge, The long edge, like a 45 degree angle...and not too much water....
