Thread: Found this at an estate sale

Thanks Marshal. Since the stone is so small I think it would lap up quite fast. I lapped a similar sized SB Ark and I know it can take some time. I can tell it's not perfectly flat but its very close. I have every grit of wet dry sandpaper and one of those granite lapping plates.

One thing that I've always wondered is how did Norton decide on how smooth or rough to make the factory surface? I'd like to match what it feels like now after a lapping. This stone is totally new. Looks like it's been sitting in that box all this time. No oil, no scratches - nothing.

Still need to decide on what I wanna do about the sticker.

If the stone is close then an option would be just to leave it with the factory finish and begin to use it. I am not sure about how Norton did it back then but I know that Dans will take the grit that has been broken down on other stones and use that to flatten their true hard stones. So it isn't a known grit. Just a loose grit that is progressively broken down.

As for the sticker, it has been suggested that you could seal it on like a Jnat and another option I have seen people use is to lift it and put it on the inside lid of the box. Just another option.
