Thread: Checking stone for flatness?

It actually wasn't old and dished, that's what gets me! The thing looked unused, but the surface was raised along the center all the way down the hone on both sides. I'm not sure if the original owner wore out their EZE-LAP diamond plate on it and goofed up in the process, or if it just came a little wonky from the mine. But that thing is a fighter.

I'm tempted to buy a throw away DMT just to finish it off, but then I'll have to sand out the scratches and burnish it.

May be the above advise on the WD sandpaper on a flat surface is how to begin?

Personally, high along the center sounds intriguing to me?
Looks as if someone was dragging the blade off both sides of the hone?....Knives!

I AM a 'center of the hone' Type!

It's size is the operative issue in that endeavoer. It's too long for the pan I used to use with my sand paper flattening endeavors. Loose grit SIC powder sounds promising if I can find a large enough piece of glass that I wouldn't mind wrecking.

That, should be easy enough!

Isn't the Norton flattening stone SiC? Should eat up most anything.

Indeed! Including it'self!

It is. And that's why I mentioned using it with slurry. Using a DMT to get some bits of that SiC loose made it faster than it already was. But whatever they use as a binder seems like it isn't as hard as it could/should be for what it is. They wear fairly quickly, particularly when used for purposes other than Norton intended. I've got a feeling if used exclusively for synthetic water hones they would last much, much longer than when abused and put to the task of flattening a hard natural.
