It's easy. Just hook that weedwhacker driveshaft from the end of the

A countershaft hung from the ceiling to turn the pulley on the compound
handle, like the old Pratt & Whitney high-speed grinder drives.

The bigger the better, for a retro visual effect to match your Heavy 10. Can
you still find round leather sewing machine belting in NY?

I haven't looked for round leather belting, but I can come up with
plenty of flyball governors and a canary that will sing when some food
drops down in his cage, which excites a cat, which jumps onto a ledge
connected to a bellcrank, which trips a pinball flapper that pushes a
big marble onto a chute....
