Also, instead of using gears to combine the motor output, I would take a look at 192's design which uses belts for the first stage of transmission. You can combine the outputs of all the cims for a lot less weight that way instead of using gears. Then just use the shifting stage to shift between a 14:40 and a 34:60 stage (both of those shifting gears are sold by WCP) to get the last transmission stage.

Did you mean 14:60 and 34:40?

Bleh yes. Sorry, I was thinking of the ball shifting gears for the primary, and the dog shifting for the secondary.
