You could get a small engine from a weed wacker or a 2hp one and mount a sprocket or pulley on the compressor and then one on the engine with a chain/belt. Might work.

"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"

try www.crazedlist.org it searches as many places as you want at once in stead of doing it one at a time on www.craigslist.com

even a bike has high rpm to run a stirup pump, and it has suports on both sides of the axle,
you know cranking or pumping is pretty much the same, a stirup pump will better utilizes your labor the only theoretical the best might be a reverse stirrup pump put in a rowing system

as for motors your guys are thinking to high in rpm the most usable will be a high torque low rpm like a drill or high torque motor and gearbox, however it would be nice to find something that I could use a lawn mower engine for
