    Third time's a charm, right?. The first two 6" by 2" tool steel
    plates I peined were both done too deeply to work with the 24g metal
    to be used in this project, so I hammered the third plate more
    lightly. I had used a larger diameter hammer on one plate, and it
    has roughly 65 depressions per sq. in., while the other too-deep
    plate was done with a smaller head and has about 125/ sq. in.. The
    newest plate was done with the same small head, but since I was
    hitting less hard the depressions are smaller, and there are about
    250/ sq. in. 

    All 3 plates are 3/32" thick, and the first 2 curved from hammering,
    and flattening became a big problem. The 3rd plate barely curved at
    all, so it's flatness combined with the shallower depressions
    resulted in a plate that very nicely rolled it's fine hammering into
    24ga copper sheet. My machine almost bogged down from being nearly
    overloaded, so I did not try to run a second generation tool steel
    plate off of the new plate. If the machine barely works for this on
    24 Cu, there's no way it will work as well (as it needs to) on
    steel. Oh well, I'll find out today what the customer thinks about
    1st generation bumpy sheet. I will also tell them that that is what
    they're getting , so they better like it (^8.
