Hey all. I've got a Norton 4/8000 stone and I think by now it needs a good refinishing (lapping or laughing, I still don't know the right way to pronounce it and haven't yet seen it in writing). There werent any help files on it in the archives and since I didn't know how to spell it (or say it for that matter) I couldn't find any previous threads on it. Its my understanding that some people use some wet/dry sandpaper along with something flat like a block of wood. My question is what grit of paper should I be using? Should I use a different size grit for each side? Is there anything else less obvious than just applying water and sanding? Thanks guys.
