Alex,

I uploaded a thread in the CD media that shows the sketch we used for our shooter gearbox (it is the same principle, just a cleaner example of it). The picture is accompanied with a description. Please let us know if you have any further questions about this.

Also, for note, we are not entirely pleased with our tensioner slot method. We have found that once you tighten down the bolt, even with a fat washer, the material gets swagged into the slot, and the blot doesn't slide freely the next time. This could be improved with more clearance (in hind sight the .252 clearance was un-necessarily close) coupled with possibly a different clamping method. We will see what we decide to do next season.
