Thread: Flee market stones

It's a coticule (glued to BBW base) ... I have plenty and I always flattened by using a diamond plate.

Get a piece of glass or a natural tile like marble or.granite. wet the sandpaper and the base which will make them stick together. And have at it. Use plenty of water. Continue until the scratches from the 400 are gone. And then try it.

Please correct me if I am wrong. Could I use a 1000 DMT after the 400? Since I do have one of those.

Just out of interest, how can you tell it's a BBW base?

I was told when I bought mine that it was backed with slate, is there any chance it's not slate but actually BBW.

Sandpaper on a kitchen worktop work very well.
Looks like it is a slate backing, not a Belgian blue: those are darker gray blue.

Dmt makes a 1200. But it isn't made for lapping. You can try it but it may ruin your plate. A piece of wet dry sandpaper is cheap enough and expendable.

I lapped mine with a 400 plate then smoothed with slurry stone

Nice find. If you got that along with other stuff for $6 then you basically stole that stone. It's always nice to get deals like that.

Yes you might be right... Never realised it could be a slate backing. All mine are vintage ones so BBW. So this means it is probably not very old. In this case the slate side has obviously seen some action . I always thought the only purpose was to give the coticule side a certain reinforcement and wasn't meant for honing but I may be wrong.

I have 2 coticules that are glued to a Rouge de Salm.

I'm pretty sure the slate backing is just to reinforce the coticule and not meant to be used for honing.

Slightly off topic but this morning I took my sharpest synth edge and did 40 laps with just water on my coti, I was going let it auto slurry, but I wasn't using pressure so it didn't.

The idea was to see how much of a finisher my Coti was good for.

The razor was laser sharp before and finished with a 12k Naniwa, 40 x strokes no pressure with the coti, 60 cotton and 100 Buffalo. It treetops, passes the HHT and is as sharp as it was but hopefully smoother, tomorrows shave will tell.
