Lately I have been chopping up scrap bikes to make things that are not bikes.
Mostly carts, but my roving mind is returning to the idea of a human powered chaff cutter made from bike parts.
I happen to belong to a bike coop/community garden,so the idea of shedding soft foliage with human power is kinda irresistible a
My idea is basically a bicycle drive wheel with concrete cast in between the spokes, to make it into a fly wheel.
To that I want to add blades, an anvil or edge for them to cut against , a feed shoot and a safety guard.
Seating for the operator should allow intermittent pedaling and feeding of "chaff" without having to get off the saddle.
I think the bike wheel/fly wheel idea is pretty sound, but the best way to turn that into something that shreds is still in question.
Right now I'm leaning towards a chute delivering plant matter to right to the flywheel,and a vee shap blade mounted at the end of the chute and sections of angle iron mounted perpendicularly on the rim of the fly wheel.
