The design was never built. The outside wheels haven't had a support designed yet and the frame is a very rough design that would have additional reinforcements depending on the special functions. The gearboxes will be supported by bolts both on the back and on the front side and those spacers are only used to space the plates apart. The gearbox assembly weighs 12 pounds with everything in the picture. The benefit of this gearbox/drive train is that the interior wheels are gear driven so there is no issue of chain or belt slippage or stretching. The gearbox plates are 3/16 in the design but i believe we are using .19" because it is much cheaper.
