    Default Seeking advice on Chosera 1000

    I have a lineup of a Chosera 1K, Norton 4K/8K combo, and Naniwa 12K waterstones.
    Strangely, the Chosera seems to be finer than even the Norton 8K.
    What is causing this?
    I acquired all three stones new, they all have very little use.

    Any advice is appreciated.

    Since this is your first post, welcome to SRP. The verb "seem" is a tricky one here: it implies a result which may or may not be true. I have never used a Chosera 1k (or another other Chosera), but I have confidence from others' reports that it should act more aggressively than the 4k/8k and 12k you mention. The only reason that I can conceive of is that your Chosera 1k may be totally overloaded with swarf (released steel particles) that have embedded in the hone, or, as received "new," the hone has a coating of wax or something to protect it in transport. In either case, a fresh lapping of the hone should remedy this and return it to its intended fighting strength.

    @Brontosaurus you are right, that is, I was only stating that the 1k does cut especially slow, I just gave it the benefit of the doubt that it could just be the type of stone. Like I said though, they all have seen very little use, only a couple hours per stone with this set.

    As far as lapping, and to possibly eliminate this, with what grit should I use to lap each of the grits 1k, 4k, 8k and 12k?

    Most of us use a DMT325 to lap all synthetic stones. They are flat and last for years. If you're going to hone its a great tool to have on hand. BTW, Welcome to SRP!

    Welcome to SRP.

    FWIW, ... The Chosera 1K comes with a small brown stone that you can use to clean off any swarf or to generate a slurry on the 1K stone. I would not suggest using the brown stone to generate a slurry on any of your other hones.
    I would suggest using the brown stone, with water, to "break in" the surface of that Chosera 1K.
    The DMT 325 is a proven performer but I have moved to using an Atoma diamond plate. Personal preference.

    Just my 2

    I use the Chosera 1K 3K and 5K stones in my lineup, I would advise you to give your Chosera 1K and Norton 4-8 K a hell of a good lapping as your Chosera 1K shouldn't appear to be smoother than the 8K, I also like using the small rubbing block that comes with the Chosera stone, it's really good for cleaning the swarf off during honing. PS the Chosera 1K is an excellent stone and a fast cutter, I never soak my Chosera stones just submerge them for about 2 minutes then I just spray them during use, dry them well and store them in a dry cool spot, you may notice crazing on the surface with some Chosera stones, my 5K has this it doesn't affect their performance.

    Welcome to SRP!

    Agree, lap it lightly and/or use the cleaning stone. The Chosera is a hard stone, and when it polishes from use, it will cut slower and act finer. I don’t have the 1k, but my 600 does the same thing, a good rubbing with the brown biscuit before use fixes that.

    Lap all your hones, as been said. And get yourself the Naniwa dressing stone, as its called. Or brown turd, as most of us call it.

    If your hones have been flattened, 600 grt. wet n dry paper is all you'll need to keep them flat, when they need relapped.

    Mine cuts pretty fast, much faster than the other three 1K hone that I have. I most often start with a very light slurry, either from cleaning it with a diamond plate or from the brown cleaning hone. I use the slurry from the presoaked brown hone to drop the grit so to speak, when I have a lot of steel to remove. The other thing I like about my Chosera is that mer the end of the bevel set, when it is mildly loaded with scarf, and I lighten my strokes up, it really reduces the depth of the scratches and makes the next hone than much quicker. It is also very quick to clean with either a very fine diamond plate or the little brown turd.
