Ok, that does sound rather obscene...but here goes.

Short and sweet, bought several Nortons used, multiple sides, thought aht the surfaces which was using had been lapped - and with all due rtespect to previous owner, I think several had - so I decided to go ahead and lap with 600 grit wet/dry sand paper that I had - First the 8000 grit- drawn grid, circular motions with paper (dry) on a flat marble tile. too a little time, grid comes off- all is good, stone very smooth, but some of the grey color form the paper stays on stone.

Then I did the same with the 4000k, new paper but my grid, in the very center of the stone, will *not* disappear. Spent some 10 minutes dry and then wet the paper, because the grit was clogged and the grid still doesn't leave in the dead center! No wonder I have been having problems getting a useable edge! Man, was I annoyed - and relieved.

Now went to hone, put tape on spine, and went to town setting bevel on 4k - now I rinsed the 4k to get the grit off, but I could *not* get all the grey color off the white stone - is this going to be a problem?

What I noticed later is that there must have been some other grit on the paper, because I have several, not a lot but a few, noticeable scratches on the surface of the stone - will this kill my honing until removed?

Now I have read hat I can use one Norton stone to lap the other, how do I do this and how do I keep them flat?

Thanks,

K
