Hah. I did the math for one of those once, and I'm never doing it again. Besides, chain stresses. Especially under high stress apps like this.
The tensioning method is the Delrin rods, like AdamHeard said. They're off center, kinda CAM ish. One will be a through bolt, to act as a pivot point. The CAM would be rotated to hold the chain tense, then a second hole would be drilled to lock it in place. If the chain stretches to an unhappy amount over time, a new piece of delrin (which is surprisingly cheap...) would be drilled and attached.

I'm sorry, but I don't really hand out CAD to something this complex. It's a much better process if teams learn how to design themselves. However, I'd love to answer any questions you folks might have. Feel free to shoot me PMs whenever you'd like, and I'll work to get back to you as soon as possible.
I'm glad people still like my designs!
