Thanks for some feedback.
Actually I've been discussing this in another thread and I've redesigned the top to eliminate the top set of beveled gears on each module.
In my original design (v2) there were in fact 3 bearings on the main drive shaft. One in front of the large sprocket, the "bearing block" a 3x3x5" block with a 5/8 shaft cutout down the center, and the "LockBlock" on the end, supporting the ends of the Gear's Shafts.
Most of this has been refined in the new design, however, and structural integrity has been taken into account. The drive now runs vertically across the chassis.
Anyway, keep the feedback rolling!
