Thread: Lapping the lapping stone

I have a Naniwa lapping stone (not the big one) and a DMT 325 diamond plate. Can I lap the Naniwa with the DMT? I understand lapping a lapping stone needs to be done periodically. I also wanted to get the honing stone residue off of the Naniwa lapping stone.

I think the DMT will eat anything, yes lap with it. I did my Norton lapper with it.

Of course you can !!!

Yup.
The DMT will have no problems eating away at the Naniwa lapping stone.
Been there, done that!

OMG - please...are you saying that the Naniwa Flattening stone I ordered, in order to lap my Naniwa 12k, needs to be lapped itself? Hahaha....when does the lapping end?

This is the stone I ordered to lap my Naniwa and to use in future...thanks!

Now I am confused, I thought the DMT or other diamond plate could be used to lap hones directly, it seems to me.that a lapping stone is just another layer of expense. I could well be wrong though, I am quite new to this.

The general opinion is to get a DMT or Atoma diamond plate rather than a lapping stone. Both the Naniwa and Norton lapping stones needs lapping....

Correct!
If you have a diamond plate then there is absolutely no need for any lapping stone beyond that

Thanks guys, I already have an atoma which I have been using, so I am glad I was doing it right
