Hey everybody, I am brand new to machining and am in the middle of refurbishing a second Atlas 10F. Last winter I did my first lathe and I am correcting any shortcomings in this second. I set the bed out to be reground and it has come back in beautiful condition. I see on YouTube a number of guys "stoning" lathe beds, milling tables, rotary tables etc. Would someone please give me the low down on stoning. I have a bunch of stones that came in my tool chest when I bought it but I don't know what "grit" they are and what "grit/coarseness" to use, or that I should use one at all, or why to use them. And should I now stone the ways of a beautifully ground lathe bed? Any guidance is appreciated.
