Re: Chain Drive Question

Oh yes I forgot to mention something FRICTION IS YOUR ENEMY. Gloified plastic chain gaurds are a large drain on efficeny. We used idler sprockets which have built in bearings. We took the idler sprockets and mounted them to a small piece of 80-20 and then bolted the slide to another piece of 80-20 and you simply slide the idler sprocket and then tighten the bolts.

It's simple and easy.
