Bought a used "Mint condition" Swaty stone off eBay a month or so ago. I lapped it with 220-400 carbide wet-dry paper on a five dollar piece of granite I bought at Home Depot at the advice of one of the "old timers" on another board. I ran a six inch machinist's straight edge across it and it was flat enough that light was blocked out which, IIRC brings the surface level/variation under 10 thousandths. I marked approx 1/2 CM grid on the face of the stone and lapped it until it was clean, took about ten-fifteen minutes. Mostly I just wanted the old/embedded steel off the hone.
I bought one of those Norton stones too, never thought to check it. Thanks for this. And I was nicely ensconced in my man space in front of the big screen, too.

Wow, that was quick. Gave my info to Norton Abrasives on Friday, and just received my 4k stone this morning. Just a bit of lapping to do, and it is good to go.

I have to admit, that Norton was pretty bad. I've done quite a bit of lapping, and actually bought a DMT XX, which is wonderful for that purpose......but I think it would have shied away from that Norton. They are good hones once you get the top layer off.
We have assumed control !

I had a king come from leevalley for christmas it was perfectly flat out of the box, I thought it was strange and good at the same time.
