Thread: blue slurry on norton?

Can you use a belgian blue to make a slurry on the 4k side of a norton, or will that mess it up?

You could do it, but it would be pretty useless.
The blue is a very slow cutting stone, of roughly the same grit size as the 4K.
You wouldn't notice it, except for the color.

Otoh it is harmless, and if you raise a 4K slurry from the norton, it will cut much faster.
However, the norton 4K already cuts plenty fast, and the blue color would probably seep into your nice norton.

Why would you do that if you don't mind me asking?

to hone with a slurry. i can't imagine another way to get some slurry on a norton without using two nortons.

Try a "thumb sized" piece of 2k wet dry sandpaper (get it cheep from the auto parts store). Lightly rub the entire wet surface of the 4K with it in circles till you get slurry.
I like to use “spent” paper… that is; not fresh sharp 2K paper, but used dull (but clean) sandpaper.


Hope that helps

wont that leave a slurry of two different grits? 2k & 4k?

The grits on the used paper are flat and more buried into the paper (because the sharp grits are worn down) and less likely to brake off into the stone but they will brake up the surface of the 4K hone to produce the slurry.
Remember the 4K hone is softer then the silicon carbide on the paper.
As soon as you get a small amount of slurry with the paper, start honing the blade, this will produce even more slurry from the hone.

Or you could pick up one of these: http://cgi.ebay.com/The-Ultra-Sharp-...QQcmdZViewItem
The same seller has a couple different grits if you don't want 600, I have the 1200. They work great for making a slurry on all kinds of stones, and don't introduce any foreign grit at all. They will also keep your stones freshly flattened if you make a slurry every time you use the stone. Pretty much the best option in my opinion.

Or if you're in the market for a DMT flattening plate, you could use that to make the slurry, or just pick up a smaller size when you order the big one.

buy a Nagura stone if you want slurry. I can't for the life of me understand why youw owuld on the 4K but hey what the hell.
