Yahhhhh, here I am day-dreaming of designing and making a grinder and
lo and behold, you've got one with a right proper old-tyme jackshaft.
(Fast and loose pulleys, too?)  And me with a box of 1.25" pillow blocks
and tripping over motors down in the lower depths of my burrow, and
maybe the odd South Bend 1" cone pulley here and there.

I don't suppose you'd have any jpegs of this Marvelous Contraption
of yours, would you?  Are bevel gears involved?  Old lathe headstocks
with backgears?  glass oilers?  LEATHER BELTS?!?  SHIPPER LEVERS?!?

I've been looking at my little shaper and having thoughts about
proper variable stroke arm designs.  I've been looking at pictures
of whiffle-tree drill presses and thinking of trepanning/edging rigs.
