+1 i am bad about lapping wetstones. I have been able to get find edges on some less than flat stones using x strokes.

alright so even though i got it from someone on ebay i could send it to dmt? does it need to be in the box?
and on the norton, REALLY??? wow didn't think you needed to waste that much material my 8k side is baby smooth but my 4k does seem quiet a bit more aggressive than i pictured half of 8k would be

could it be that the extra course diamond plate is leaving marks in the norton,whenever i've lapped a stone with a coarse stone it's left marks and i've had to use finer stones to finish it properly

not seeing that as that problem cause my 8k side is scratchless

Here is there contact info. Give them a call during biz hours and let them know your plate is not flat. Make sure you check with a straight edge before you go to the trouble. It has to be out a certain amount to be out of tolerance to the point that they will replace it.

thanks! i will try

I have a DMT 220/325 (8x3) and one side is definitely NOT flat. If I lap a stone on the 220 side until the pencil grid is erased, it seems flat. But if I then do the same on the 325 side, the pencil grid is only erased in the middle of the stone, and it takes considerable more lapping to erase the rest of the pencil grid, depending on the hardness of the stone. I finish lapping with, and hone off of, the 325 side, and have no problem, so I suppose it's the 220 side that is not flat. (Is "unflat" a word?) However, it could be that the difference in unflatness (seriously, "unflatness?") is visually striking but so very minor that it wouldn't matter in the honing process. I don't know.

I do know that DMT will replace a stone, but it takes two months. I did it once for a 325/1200 combo that was losing its diamonds, and it was a no-hassle experience. Send it back, they test it, and send you a new one. No questions. They even included a few extra (slightly used) goodies, like a 325 DMT credit card for making slurries. Good company.

Anyway, good luck with your stone. =)

thanks for the info. when i use my 8k side i can see that all the water is pushed away right to the stone in like the center inch so maybe same type of scenario where the middle of the dmt is a dish
