Thread: Lapping a Coticule

Do you lap a coticule with the same materials and methods as other stones?

Yes.

(Apparently my answer is required to be more than ten characters. I believe I have accomplished that now.)

could I use a diamong hone on it?

Yes.
A diamond hone/plate will work just fine. You can follow exactly the lapping method described in Hone Lapping 101 in the Wiki.

Yes, you can. I suggest a 1500 grit wet-or-dry sandpaper or even 2000 for the finishing touch. Up to you.

Sorry, but I disagree. There is no need to finish with such a fine lapper. A coticule surface after a 325 grit diamond plate is just fine. A coticule constantly refreshes itself by releasing grit. That means as you use it, it is smoothing itself out, eliminating the need for lapping to a smooth finish.

Works if you're bored... but I agree with Utopian. Whatever works best for you.

A DMT 325 is all I use on my cotis. Utopian is correct that the surface becomes constantly refreshed with use, especially if you use a slurry stone.
