You just wrap electrical tape where you want the polycord and the belt walks back into place if it ever moves. Also, it allows for a smaller gearbox ratio which further saves weight.
We have been looking into this as well. How do you go about welding it? We haven't had much success in our limited attempts.

No we didn't, we did have a few come undone because we didn't make the wires long enough or didn't strain relief properly.
