Thread: Curve on a norton set of stones. Maybe.

Just got my DMT 325 in the mail. Can't wait to get these pups lapped.

What would the experienced decision be? should i send them back or is there a way to correct them my self. Or is this just a trait of the stones? I dont have any idea. I'm new to this whole experience.
Not to mention they aren't very square. But that's just something that bothers me as a mason.

I noticed the same problem with my Naniwa 3000/8000 superstone. It is slightly bent upwards from the 8000k side.
I have been soaking the stone for 2 hours now and it's still bent.
While not in use, I store the stone damp in plastic bag.

Should I let the stones dry before storing them?
If I lap my stones now again, how likely will I be in situation where they have "unbent" to the original position and as I lapped them, they would be again bent?

Just got finished lapping two of the three sides of my stone set and about halfway through the 8k side of the 4k/8k combo. Was blown away by the difference in texture after they were lapped to how it feels on the sides. Thanks again to ItalianJoe for posting the vidoe by gssixgun, and gssixgun for making it. Was super helpful. Expecially the suggestion of marking grid lines on them.
Had to take a break and give the shoulder a rest.

Here's the hones after the DMT 325
Not so awfull. Pointers and tips are welcome. Especially if you see something in the pictures that doesn't look right. Wont learn if I keep doing it wrong.
