    Abrasive cord comes in different grits and diameters. Amazon, MSC, and certainly other vendors carry it.

    Good thoughts from you both. I have a torch cleaner, I'll see if I can find it.
    I'll check into whether the available abrasive cord comes thin enough. It will be handy for other uses too.

    Thanks.

    220 Rhynowet won't fit in there folded up... did you try 400? It's thinner paper and folds better, and can still get a lot of work done. I use more of it than any other grit.

    . this^^^ I use a Flex Shaft with 1/8” Carbide burrs to make the first cut, which is my only cut because I grind after HT, one and done! Still using the same size burr worked back when I had to do it twice... once pre heat treat & once after!———————Stay Safe & have fun!

    Thanks Laurence, but, the jimping is very fine and the need is to do this post heat treat. The scale wont release with brass brushing or scraping with what I have tried.

    Do you have some small metal sheet? Shim thickness , perhaps a thin piece will fit and take out the scale? Or you could start a fashion trend! Brute de Forge jimping!;) Years ago. I did that on the spine of a couple of fighter type blades that i ground from Stainless. It was well received!:thumbsup: Let us know how it works out!

    I personally would do exactly what Salem suggested and just keep going up in grits until one fit when folded, even up to 1000 if I had to. It'll take a bit more work but just keep folding to a clean section every few passes. Before using the paper though, I would use a needle, such as a leather sewing needle, and try to scrape out any thicker gunk with it. Be creative :thumbsup:

    You probably don't have these, but I have a few boxes of various types, sizes, and shapes of mold makers stones (EDM) from Gesswein than can be shaped to fit whatever you need. I would take one of my really thin ones that are about a 1/16" thick and use a diamond sharpening stone or something to taper one of the edges (or ends) to fit the jimping. Just another idea.

    Right now it just looks grungy. If the spaces were wider, maybe.
    Thanks Laurence.

    I have not tried 400 grit, even though I have some. I was thinking about how hard the scale is since I have tried to scrape it out using a very roughly edged knife and it wasn't working very well.
    I'll give the 400 a go and see what happens. I imagine I'll probably go through a bit of it.

    Thanks Salem.

    Hey Paul.

    I'll continue to look around the shop for more "creative" solutions.
    I am leaning towards purchasing a jewelers saw with handle and some abrasive cord, as I have a few like this to clean up.

    Thanks.

    Looks like Gesswein offers that as well. ;)

    Definitely looks like it could be a good solution to such a problem. I just may have to pick up some for myself. :thumbsup:

    Edit: wow, they have sizes all the way down to 0.012"

    Thanks Paul.

    I have found a few places to purchase the Mitchell abrasive cords.
    And yeah, I think it is going to be a true friend.
    Now how many different diameters to buy? :)
