Thread: odd lapping method

So I did something I haven't read about but tried and it worked. I lapped an old coti I got from flea market on a slab of granite. I started with wet/dry sand paper till it gave out and I didn' have anymore. Then lapped the rest flat using the slurry. This gave me the idea. So I saved all the liquid in bowl and let it evaporate. Then today I needed to lap a stone so I took some chuncks of the dried slurry put it on the granite and added water. Then lapped a stone. Seems to have worked. Any reason not to do this?

-------No.

Works for me
Started with 360 grit on a glass sheet, then got this marble table top I use for honing on,
I just lap on it when I start honing works great

If it works for you there is nothing wrong with it

A member here (I can't temember who) told about an even more odd method. Concrete floor. I wouldn't put my rocks through that

Yeah don't think I would do concrete floors. The marble is a big smooth chunck and the slurry is from coticule so the abrasive is the same as the stone and works pretty quick because of that.

If you have a sandblasting supply shop near you try buying the Garnet sand called Almandine .it works well.cheers.

Some here might remember the practice of applying old slurry powder onto leather strops. I guess not much different than paste.

Any other uses for used slurry??
