Re: Dragline Crawler Build
Jim-your thinking is right on with this. The dia. of the tumbler dictates the size of all the other parts. You may have some work to do on the tumblers but I think you are on top of that. Personally, I would go with the metal chain but finding the really small sprockets may be a challenge. Does the 1/4" chain look too big? You might find something smaller in some clock works sites-not sure. Keep the pictures coming.
