    bike powered butter churn

    I'm trying to think of a way to build a bike powered butter churn. My wife has started making homemade butter by shaking whipping cream in a jar. It works but takes a while and it's alot of shaking.

    I'm interested in designing a bike powered shaker of some sort. I'm thinking of a roller attached to a wheel which has an offset arm, something like a train. as you pedal it rotates the arm in a circular motion, shaking the jar.

    I'm not very inventive though, so if anyone has any ideas to help me out that would be great.
    I can bike to work faster then my neighbour/coworker can drive. So much for cars being Superior.

    I was thinking if I built a large a-frame stand to hold a spare wheel, that I could build a bracket/holder that I could strap the jar into and then hop on the trainer and every spin of the wheel the jar would shift slightly, and gravity would help shift the liquid.

    Opps, nevermind, just realized it would be the old full bucket of water swinging around and it doesn't dump trick.

    Just so happens I enjoy old technology. You can just a revolving barrel like the Star barrel churn on this webpage:

    Do you own a blender? Or a mixer? I just buy a quart of cream and put it in the Kitchen Aid mixer, turn it on and come back when I hear it thumping around. Take the lump and press it out between paper towels and rinse under cold water. Fold in salt to taste. Done.
