It is very likely that a significant number of those DMT hones will fall within the Max allowable 0.0005" specified by Shapton, just as I'm sure a good portion of the Shaptons will actually be slightly better than the maximum allowable by their specifications.

In the end, you pays your money and you takes your choice. The lone advantage I can see is the pattern in the surface of the Shapton... it would allow for water/slurry to escape more quickly and perhaps flatten the hone somewhat quicker but I don't see it how it could make all that much a difference. One thing I know for sure, I'd rather drop a D8C on the basement floor than the Shapton GDLP!

I for one would stick with a D8C and spend the saved cash on more hones.... not that I have HAD.

Hey, quit poking me!

I agree with you, the DMT D8Cs on average could very well be flatter than .001". I actually took the one I had to a local active machinist with decades of experience. He thought my interest in checking out the flatness of that lapping plate was interesting enough to throw caution and in the end one of his older but accurate dial indicators to the wind (D8C ate it up in the testing process of course). Mine was within the .001" tolerance and the flatness varied across the surface of the plate but stayed within that range.

Agreed also that the GDLPs on average could step outside the .5 micron flat claim. I do like mine for the recessed surfaces as it really helps during lapping. Even with the recessed surfaces, toward the end of the lapping process I can life the GDLP and the stone held by it in the air for about 3 seconds. Impressive in my book.

I tend to use the 4K and 8K the most followed by the Escher, but that is because I have simply had a ton of success with these. The 16 though is very consistent. I won't be buying the 30K either, but it is tempting......lol.

I am going to buy a back up 4K and 8K..........

These stones have been superior for results and consistency.

Have fun.

Lynn, when you say you use the 4K and the 8K most, are you referring to the Norton or the Shapton ceramic stones? Did you mean you're going to buy a backup Norton or Shaptons?

Thanks guys.
