I could use 2''x1.5'', if all else fails, but that's significantly heavier and takes up more space.
Very interesting. I'm assuming this is a drive train with the wheel axle supported by bearings on both ends, not a WCD style drive train, where the center wheel axle IS the gearbox output shaft. Correct? Got a sketch?
