water stone ???
Bruce, a MN Galoot
>I picked up a 6000 grit waterstone a couple months ago. Problem is, it glazes over so quickly that I have a hard time using it without resurfacing each time. I don't know the brand because it is at home and I am not. I know it's not a Norton, Shapton or King. It didn't cost all that much, maybe $20 - $25.
Is this a problem with the stone or the operator? I don't have a Nagura stone and wonder if that would be a solution to this problem.

>Maybe you not getting it wet enough try keeping it in water for a few days. Shouldn't be that hard to identify it just look thru the online websites and see which one it matches.

>I use an 8000 Norton and have never had that problem. I do keep mine extremely wet. I store it in water and pour water on it as I use it by scooping it out of the tub it stays in (just the cup of my hand kind of thing).

>Bruce,
All a Nagura stone does is to whip up a bit of slurry. It's very useful, because otherwise it takes too long to create enough slurry with just the tools you're working on. But I can't see how it would have anything to do with the stone glazing.
I agree with the others that it sounds like you're not keeping the stone wet enough. I always have a spray bottle filled with water on hand when I sharpen. It's just right for keeping enough water on the stone without washing away the slurry. I also keep all my stones wet, even my polishing stones. I've found that dry polishing stones suck up all the water I put on them until they're pretty well saturated; so I just keep them saturated.

>It's a Suehiro 6000 grit. My others are both King 800 and an S-3 of about 3000 grit. Neither of the King stones need to be soaked much, although I keep the coarse one in water.
My interest in a Nagura stone is precisely what you mentioned - develop a slurry in a hurry, but I also thought it could help get rid of the glazing that is happening.
I thought I could get a good finishing stone cheap. I think the old adage is true: you can have good or cheap, but not both.

>-Some stones I find will load up if you don't keep them wet enough. So it may be a question of not enough water in the stone, or on the stone while you're using it.
-If it's relatively new, that may be part of it, too. Some stones, like some of my kings, are sort of glazey from the manufacturing process, and it takes a while to wear it down to the good part.
-Depending on what you're flattening it with, you may be clogging it up with extraneous crud. If you're flattening with the wrong kind of sandpaper, for instance, some of the grit can come loose. Stick with teh wet/dry stuff, and don't be shy about it. Or, alternatively, flatten your coarse grit stone and flatten with that.

Using enough water PLUS the nagura will do the trick. The Nagura is important - vital - with stones of 6000 and above to clean the surface AND release fresh grit from below.

>If you can't keep it wet enough, you're obviously using the wrong kind of water. Forget that stuff you get out of the tap, or even out of the designer bottles. What you need is some heavy water, Deuterium Oxide, D2O.
