That's some cool stuff! I bet a guy could really move some air with a PTO compressor. I'd love to find one. I can only imagine the fun I'd have with a 35 hp air compressor (given a 45 hp tractor with 35hp assumed after parasitic power loss at PTO). Maybe a rotary screw style, tankless, compressor could be adapted? No tank just air, like some pull behinds. Got thee ole gears turning again.

With those 302 fords, were they still internal combustion engines on the one bank? I don't quite understand it. I understand suck, squeeze, bang, blow is how an engine works. Four cycles, five events. That sounds way cool.

The possibilites with air tools is endless. It would be nice to be able to use a one inch impact away from the shop. Or a jack hammer (for when a concrete drum stops turning when full off concrete and the scrappers are called to get the drum after it's hardened), or to be half the power behind a plasma cutter (for those aluminum jobs when a demo saw starts kicking my butt).

Thanks Gus.
