Actually, that's not REALLY my question. My question is: How many of you out there use a treadle wheel? If so, do you have any wheel design advice? I am working on a plan with a friend of mine to build a treadle wheel. I know the basics but was wondering if anyone has a wheel made with specific materials/design elements that they love. Or, better yet, are there design elements that you find yourself wishing that you had? Thanks so much everyone!
