    I was able to resurface a very abused Oliver rolling mill using my
    10" Atlas metal lathe and a toolpost grinder. It took a lot longer
    than the operation would have taken on a cylindrical grinder, but the
    end result was perfect rollers. The rollers themselves were hard
    after the operation but I probably only removed about .002" of
    surface. 

    I held the rollers between centers, as they already had centers (a
    60 degree conical hole) in them from the initial manufacturing. 

    No real point to this except to say that it can be done by most
    competent machinists, especially if you seek one out who has a
    cylindrical grinder. Of course later that year someone left the
    window open in the shop during the rainy season (in Oregon, any time
    of year) and the rollers ended up with a rust spot. So I'll be doing
    it again... 

    Before I resurfaced them (must have been several years ago) I asked
    on Orchid about it and the folks from Durston said that they also
    will resurface rollers. Might be worth it to check.
