Wow, that's pretty sweet! With a handle on top to aid cranking or maybe a gear reduction to not work yourself to death..... looked like it did a pretty good job. I've got a ton of old bicycles around here, maybe I could rig up something I could sit on and pedal while Mama did the squirting. I *really* like the idea of a "man powered" machine versus electric., maybe my best bet is making one like this one but going through the trouble to improve upon it enough to make it more workable.
Oh, for folks who don't have the washer/dryer connection, I had a new A/C unit put in last year and the guy said they just recycle all their metal and stuff. Probably wouldn't be too hard to hook up with an HVAC company to get a free motor either.
