    Good News : I got a 1/2 hp gearmotor hooked up to Little Pepe, 287
    in. lbs. of torque compared to 45 that the 1/4 hp motor I'm replacing
    had. Some serious beef and it looks like I'll be able to roll
    buckle-sized plates of steel, maybe as large as 3" by 4". 

    Cautiously optimistic, and yes, if I knew what I was going to end up
    doing when I got the Pepe almost as an afterthought, I would have
    looked harder into mills... and probably not even have taken over
    ownership it. 

    But anyway, the gears on mine seem to be able to take some abuse,
    though we'll see how they hold up over time... over time. The thing I
    discovered as what I have to call a design flaw - even though it may
    technically not even be one, because what do I know (?), I don't
    design tools, I beat them up - is the way the gear on the bottom
    shaft is attached to the shaft. By a little biscuit that sits in a
    little recess in the shaft that's only about 2/3 mm deep. The biscuit
    sticks up into the slot in the gear a nice 2mm or so, but there
    should be a nice slot in the shaft too, a nice, normal, keyway and
    square key like normal shafts and gears are done. 

    The recess and biscuit on mine are stripped out, so now the drive
    shaft doesn't drive the top shaft, it just spins... Time to get 
sneaky
    with the flexshaft and carve out a squarish slot in the shaft so I
    can put in a nice, normal key, since I have no intention of sending
    it off to be repaired. 

    Also anyway, the next chapters of the hammer texture rolling mill
    saga are on hold...
