    M'Lou Brubaker, thank you for catalyzing the following idea (and
    thanks Jesse B. for all the other input to get my rollers turning, so
    to speak). 

    MB's idea of hammering a steel plate and running metal against it in
    the mill is very good, because using a blank of ground flat stock
    tool steel (my idea, and I work with the stuff every day) eliminates
    the big problems of using a hammered block or plate to generate a 
wax,
    which gets cast into a roll plate. Those problems (I mentioned at the
    start) are the need for precise, uniform thickness of the 
wax/casting,
    and maintaining flatness along the short axis of the resulting plate
    (about 6" by 2", rolling in the direction of the long axis). The
    first casting I got demonstrated the high difficulty of achieving all
    that, so I really like the idea of using a piece of say, 1/8" thick
    tool steel and hardening it after it's hammered. 

    MB's idea only takes the concept I need halfway, because I need a
    production plate with bumps on it, that rolls depressions into the
    metal (24g ss), whereas a first-generation hammered plate with
    depressions will roll bumps into the ss sheet. So I'll need to use
    the hardened steel plate as a master plate to roll production, second
    generation production plates from, maybe in some thick brass which I
    can heat harden in a kiln. These plates will have bumps and will
    replicate a hand-hammered, peened texture. Yep, I think that's the
    way for me to go. Relatively cheap and easy ; I can do it in less
    time and trouble than it's taking to find out about having a custom
    cylindrical roller made for a mill, and a wad of cash less costly.
