It looks like you could make the outer wheels dead axles, which would make it easier to manufacture.

A live axle requires a keyway/hex feature and some sort of retention for the wheel/sprocket separate fro each other. |

There's also the option of throwing a tensioner block into the system, probably an off-center mounted delrin cylinder, but that kind of defeats the purpose of "ease of maintenance". |

Re: pic: Chain and Wheel in Tube
To be quite honest, that doesn't make the machining any easier.. The way my team does it, which is not the best way to do it but is perfectly fine for FRC requires the same amount of machining. In 2014 we were able to do a c-c belt drive train on a manual mill with no issue. It used the same bearing setup as shown in this picture. Either way, it would be a bit on the mill properly spaced the correct distance from the last hole. We use a 1.125" mill bit to drill bearing holes and have had no issue with tolerance thus far, we do not us a CNC.

We have a mill with a digital read out it's pretty useful. I think the best thing about c-c drivetrains is the fact that you don't have to mill slots for bearing blocks. However, with all of the new vex/wcp parts now pretty widely available, adding tensioning cams to the drivetrain only requires one more hole drilled in the tube. the WCP bearing blocks are huge time savers.
