As you said earlier you used 1/10, was it for this type of swerve/crab setup or for a 6-wheel? As a mechanical engineer I would take the advice of fellow mech-heads and increase the width of your side plates, 1/8th is the smallest I would go with major cross bracing. Looking at your setup your main drive shaft is about 6" away from your main mounting point for those side plates, and that type of torque on 1/10" sheet won't last long. Take a look at some of the more successful crab drives of the last couple years (i.e. 71, 111, 1625), and make your modules beffey to start and slowly cut away the fat as you improve the design.
