2x1x1/16 Belt-In-Tube

[Everett33]

During the off season after having seen so many different chain-in-tube drivetrains, I decided to create my own iteration. All of the components used are Vex-Pro. I initially started with #25 chain, but I didn't like the sound the chain made when it slapped the inside of the tube. I moved to 9mm belts for the weight savings, ease of ability to assemble, minimal efficiency gains, and the smooth and quiet operation it provides. At the moment the design is untested, so I am not sure how well the 9mm belts will hold up on a drivetrain in competition. The current iteration uses the plastic clamping bearing blocks, 30" of 2x1x1/16 aluminum tube, 24t 9mm belts, with a spacing of 12.4" C-C between axles. The weight with #25 chain was 2.768 lb, and the current weight with the 9mm belts is 2.562 lb. The only thing it needs is a set of the WCP cams to keep the belts taught.

Let me know what you think or how it might be improved upon.
