 But that is not all-FIRST is about teaching mentors what kids are like all over again. It's about closing the generation gap, creating bonds, life time friends, and skills that will last everyone involved a lifetime. - Team0 [more] |

Re: Sprockets as Chain Tensioners?
You could try a cam....see the picture below. Each cam has a 1/4" shoulder bolt that acts as an axle. The bolt is drilled off center. You twist the cam into the desired position then tighten a set screw....this drives the aluminum cam up into the bolt and locks everything down.
As the delrin wears you can adjust the tension or replace the bushing altogether.  |
