Ok, I have a chinese stone (c12k) that was working great as a finisher and I made the mistake of trying to flatten it with a norton flattening stone. Now the surface is a mess. It's gritty to the touch and makes a complete mess of an edge. It turns a ready for finish edge into a butter knife edge with about 2 stokes.
How do I get it back into finishing shape?
Thanks!
I did the same thing with the same results, then I used a DMT 325 an it looked much better but still a little scratchy. I would say a finer diamond plate would do well to dress it nicely but I haven't had the opportunity to try it.Quote:

Just watch out for stray grit in the higher stones
I scrubbed the stone with a brillo pad to remove the grit and small particles of sometime that looked like rubber cement -- bonding agent maybe? Then wore out 3 sheets of 3M 1000k wet/dry sand paper on a flat ceramic tile. The stone is back in action. I think I'll just keep my natural and manmade stones separate from now on.
You can scrub natural and man-made stones together with no issue, it's just that the SiC flattening stones are very coarse, so they don't leave a surface that's conducive to razor finishing. You need to smooth the surface of hard stones like the C12k or you will never get a good finish. The chisel burnishing that works well on Arks works pretty well on them also.
Did u scrub the stone after the 1k lapping. The reason I ask is ur post sounds like u only scrubbed before the lapping and not after alsoQuote:
