Summer Project - My first Gearbox

[marccenter]

Dear CD,
Finally got around to creating my own gearbox using the Andy Mark Nano as an example. I had access to a water jet to cut the outside plates. The rest are parts from Andy Mark. Final ratio is (50*50*50)/(14*14*14) = 45.6.
The outside dimensions are nominally 2" by 4" by 8". The two, intermediate gear shafts are 3/8 hex supported by 3/8 hex bearings on both sides. The single output shaft is 1/2 hex output.

I could have used this during the FRC2013 season. Now that I have designed one gearbox, the next one doesn't seem so daunting.
