If C channel was strong enough in the same application, then I guess go with it again. I just prefer Box tubing over C channel because it is stronger for not much more weight (and the strength gains outweigh the weight gains).
For that outer plate, if you really want to do it, I would use some C channel or box tubing instead. Just going to 1/4" plate would be rather inefficient. Using C channel how
488 did on this base is a much stronger option than just using plate. Once again I would prefer box tubing for the extra rigidity, but that's just me.
As for the gearing, you'll find that the cost of AndyMark gears is very nice (same for their quality).
The 14T pinion for the CIM motors
The 40T gear
The 14T gear with a hex bore
The 50T gear
You can probably even find a way to use AndyMarks various shafts (from their gearboxes) to eliminate even more custom parts from the design.
