I use a DMT ultrafine hone (I think it is 1500 grit) to lap my coticules. I draw a grid pattern on the face of the coticule with a pencil, then do circles with the DMT on top of the coticule while running it under water. I change directions and flip the hones around to ensure even wear. After the grid pattern is gone, I repeat the prcess a second time (which should be quick, if it is really flat...)

If you don't have a slurry stone, the DMT is also a quick way to work up slurry fast...

Use only DMT 325 FOR Lapping any other stones. if you use high grit dmt sooner or later you will loose diamonds . gl

Never lapped mine and it works great.

+1 on the hone lapping article in the wiki. My weapon of choice is a DMT6C (though I'm finding recently that larger would be nicer...). For Coticules (and other "soft" hones), I find that the DMTC leaves a very smooth surface (though "hard" hones will have some light scratches left behind).

Another yes vote for the D8C. Plus it can do double duty if you have big chips to grind out.

Sham's right; anything finer than the C (325 grit) & the slurry will eat away @ the nickel holding the diamonds in place w/ predictable results...

Yep what he said

sweet beans!, i just drew a pencil grid and used some different grits of sandpaper and all is well and flat now!.

My method: sandpaper on a flat worktop.
