    What at first looked like the bottom of a recess in the shaft was in
    fact the top half of the keyway biscuit that had sheared clear
    through. The top half of the biscuit is what looked at first to be
    the whole biscuit, so then I had the issue of replacing the biscuit.
    Fortunately I had some 1/4" tool steel, so I sawed a piece and
    sanded, and sanded, and sanded til it fit down in the recess, then I
    torched it and quenched it and now it's in the kiln for a temper. The
    gear itself is not very hard at all, which is good I guess, in that
    that means the teeth probably won't break off. But soft is soft, and
    with what I'll be doing with the mill, it won't surprise me if that
    becomes another issue down the line. So I won't temper the biscuit
    very hard, because I don't want it to tear up the keyway in the gear
    or shaft, and because I don't want it brittle. At least now I know
    what I'm doing to my little Pepe, and that I can fix it , and write
    about it, in less than the time it would take to track down a
    replacement biscuit. 

Stay tuned...
