Jon,
That pedal power'd Scoll Saw is an AWESOME one!!!!!! I would actually build such a thing if I could see how it was done!!!!! Thats an AWESOME idea. only stops when your legs can't take no more!!!!!! PLUS, you get your exercise all at the same time!!!!

Follow the link in my post, there are patent drawings and many photographs of similar devices. It wouldn't be too hard to turn an old stationary bicycle exerciser into one, I'd think. I've also seen grinders of that style, I'm pretty sure I remember watching Tubalcain/Mr Pete mess about with one on youtube.

Doesn't look like the old bloke (er youngen) is even breaking a sweat=go on for ever. Looks easier than peddel lathes I've seen in action.

as clunky as it appeared during movement the blade appeared pretty steady & smooth in action without cutting anything: cant help but think twyne could have made the process less chunky but then it would be similar to others & not original. His breath was less steady
