    Failure Is Not An Option (it's required stops along the road to
    success) 

    So I found out the hard way that if you hammer (peining again)
    depressions into a steel plate that are deeper than the thickness of
    the metal you plan to roll through the mill with said plate, said
    metal cannot be fully forced into said depressions, which, if I 
wasn't
    so stubborn, would be depressing. Here, 24 ga sheet has lots of flat
    spots where it couldn't fill the low spots in the steel plate,
    whereas 20 ga sheet has enough mass that it does get pushed fully 
into
    the pein marks. The customer is using 24 ga. 

    Now I have to hammer new plates, being careful not to hit very hard,
    and really make sure the plate is flat before I harden it. Thick
    plates warp less but can be almost impossible to flatten. Thin plates
    warp a lot but flatten more easily. 

    The second massive lesson today was that my rolling mill motor (1/4
    hp) isn't strong enough to roll hammer texture into a 2" wide tool
    steel plate, even if the plate is red hot. Maybe, just maybe it will
    roll a 1.5" plate with shallower depressions, but I'm not very
    optimistic at this point. That is not a fatal drawback to my project
    because the customer likes the result rolled off of the original
    hammered plate, that result being bumps, not depressions, instead of
    the originally desired replication of hammered depressions. 

    I took some pix of all this and will let 'you' know when they go up.
