Spinning Wheel Design (Idea)
Was just pondering spinning wheels since my housemate’s boyfriend built her an electric one that works pretty good. However, it IS electric which means it is still post-industrial revolution and requires a 110V 60Hz power hookup.
What if you cut a bicycle frame (see photo) such that the sprocket, gears, rear wheel, and seat were all still intact. You could attach a treadle to where the crank-shafts once were and make sure the rear hub couldn’t rotate freely. You could run the gear changers (if it’s a multi-speec bike) up near the seat post allowing the spinner to change speeds. With the wheel no longer on free-rotate, the break would be unecessary.
The flyer, bobbin, and other-parts-I-don’t-know-the-names-of could be attached to the seat post and the quick-release used to quickly adjust distance from the wheel or to remove that section for necessary repairs, loading, etc (again I don’t know enough about spinning wheels to judge what is necessary there).
One thing the boyfriend mentioned was the difficulty of keeping costs down… I’m sure you can find part of a bike to use for around $20 and it comes with so much built in. If anyone ever implements (or has already implemented) a design like this, please let me know. 🙂
