does anyone know of some kind of compressor that can be mounted on the end of the crank...preferably where the stator goes?? I was thinking about converting a a/c compressor, but it needs oil and that just creates another problem. The more CFM it willmove, the better.the other idea i had, was machining something sorta like a rotary rx-7 motor.....that would work, but im tired of payin the machine shop to make sh!t
