So I picked up a combo Coticule/BBW on BST, but it isn't coming with a bout. Is there another way to build slurry, or a good way to get either a bout or something can can raise slurry that will serve another purpose?
Quick One: I need to make a slurry

A slurry stone can be purchased from eBay,a number of net stores, and classifieds.
A slurry stone is really the best way. You can however, if you have a small diamond hone, make a slurry from the stone but that would not be advisable in the long run since you will not have a flat stone after a short time. I know, I know, you want to try it out now! 
Make sure you order the stone, they are fairly cheap.
Take care,

I just got a coti/bbw slurry stone from straight razor design for 18.00 not counting shipping
Buy a DMT8C. Use it to lap hones and slurry your coticule.
Or buy a coticule slurry stone off someone. I'm sure lots of people have extras.

See, I like this idea a lot - I see the DMT8C (325 grit, amiright?) references continually as a great lapping stone, and I was hoping it could build a slurry as well. Seems like the same approach you take to lapping, if only done briefly, would build a nice slurry as well.
Can a few more of you experienced gentlemen comment on that train of thought? I seem to think this would reduce the need for re-lapping very often as well, as you'd wear it semi-evenly.
DMT s release loose diamonds that scratch the bevels, if you do not care about that then DMT will work for you just fine.
I personally believe in the slurry stone approach.

I think that if you contact Ardennes directly, they might be able to help you out.
They are great to work with & very nice people!

So how do you lap Coticule/BBW?
I think the difference is when you lap your stone you will wash/rinse after the lapping, so any loose diamonds will go down the drain. Whereas if using the DMT to raise a slurry there is no rinse, so any diamond that end in the slurry will remain there whilst honing.
Note: I'm not saying using a DMT to raise is a slurry is good or bad. I'm indifferent - some say it works great and other don't do it. I happen to have a slurry stone, so I use that.

I agree - that's what I find. However, I just went back and watched heavydutysg135's polishing videos and he uses a yellow cotigura to raise slurry on both the bbw and yellow coticule. So that's all I'd need - a yellow cotigura, right?
Yea, really. I have a Coticule coming that has some dings in it that need to be lapped out and i was gonna use the DMT.
Jared, you are correct. My newb knowledge could have sworn that was a coti/bbw but what do i know.
I have been using a DMT 1,2k credit card size for slurry creation on very hard stones in the range of 30k.
And boy am I picky when it comes to scratches and I have never seen a scratch left from a loose diamond from my DMT in the slurry.
The credit card size DMT are cheap and work perfectly for slurry creation
but not for lapping though.
600 grit paper has not been working for me,
as it has indeed lost grit and contaminated my slurry. But this could of course be just me and my paper.
A identical stone in smaller size is the perfect way, though
Lapping is fine, because you wash the stone during. When you are raising slurry you are leaving it on the stone.
I use a small chunk from the Nakayama Kiita. A good friend gave me this and told me it was harder and finer than probably any other stone I would rub it against.
You could do that, but one of the nice things about a BBW is that you could use it on its own without the assistance of a coticule (or use it in conjunction, i.e. between bevel setting on coticule slurry/dilucot and coticule with just water). In this case, you loose some of the properties of the BBW, most importantly the fact that a BBW with slurry has been shown (perhaps always? I think research is still underway, and I won't divulge anything about Operation True Blue) to leave a keener edge than coticule with slurry.
Also, I'm of the opinion that the term "cotigura" needs to die a quick, painful death. The only similarity between a coticule slurry stone and a nagura is that they're both rubbing stones.
Now, if people want a cutesy shorthand name, I suggest coticurry!It's true, but some of the sources mentioned already are more convenient for purchasers in the US. Also, it looks like thesuperiorshave.com may have combo slurry stones if you ask by email. I *very* highly recommend that vendor.
Yes, I've had that happen before with DMT cards too. Maybe it was because mine haven't been broken in yet, but it was still annoying. Also, I notice that, when using a DMT card or sticky, the slurry turns dark fast, indicating quick wear to the DMT hone. But I've had nothing but good results using my D8C and D8X as lapping plates with coticules.

Thanks, danjared - I'm contacting them about a combo slurry stone. I think that's the way to go. I'll probably end up with a DMT8C at some point, and may try that for slurry, but I would rather "do it right", you know?
