Once again, forgive me I haven't had a chance to tear into the thing yet, but I thought of a potential solution many teams may be able to implement and perhaps make several of to supply to other teams in trouble.

Would it be possible to machine the planet carrier and output shaft from one solid piece of steel? Start with round bar the diameter of the carrier plate, Turn it all the way down. I know it's a long ways to go but CNC can help with that. Drill new planet pin holes. Cut a keyway. Is there any reason it must be two pieces? If we did this, what material should it be made from to not yield the material due to torsional shear where small diameter meets large? I would like this to eliminate any possibility for failue in the 2 motor 12:1 scenario.
