I've heard that before and accepted it as reasonable. Now I'm thinking about it and I'm not so sure. Does that mean if you lap a 12K stone with a DMT 325 (about 45 microns) that you get a grit of 325 for some period of time? How long? Is there anything one can do about it? Even using an ultra fine DMT plate (1200 grit, 9 microns) you would still ruin the usefullness of a 12K for awhile. If there's general agreement that this is the case I'm happy to accept it. I just hadn't thought it thru till now. Thoughts?
