OK, my motors are DEFINITELY too small for that. Unless you get lucky on
eBay, I think you will have to spend some money on motors that size.
The treadmill
motors likely are big enough, but there's been some question about
smoothness
and reversing on these motors. Also, are they ball bearing? Constant
stops and
reversals, as well as mostly low-speed operation is hell on sleeve bearings.

C&H is a great place, but they know what they have, and are NOT cheap.
