Chain Tensioning Method?

We're thinking of doing this also this year. We're tired of slots where the axels go, they're a pain. Anyone done the "delrin pushing down on chain with the 2 screws attached to the delrin and chassis" that can offer up any advice or pics?

We're thinking about designing with a sprocket spacing that allows for the "perfect" distance (exact number of links). There is a spreadsheet to help with this in the CD-media white papers.

I know there will be a little chain stretch, but we're hoping to run without need for tensioners. Anyone have experience with this method?
