Having experimented with this kind of space saving, we eventually came to the concussion that the most efficient method is to flip the motors around. 971 did this in '12 and '13 and our ball shifting gearbox copied that this year. (The most similar example may be Texas torque's gearbox from last year, I believe it was a vex ball shifter with custom plates so the motors hung over the wheels)

That said, I really like this and the out of the box thinking behind it. It reminds me of the things I thought about when planning 192's '12 and '13 gearboxes. I've worked with right angle drives, the construction technics you seem to be using and bevel gears so let me know if you have any questions.

I am glad you like it and as for the bevel gears I am using CAD files from here (http://www.qtcgears.com/KHK/newgears/KHK228_2.html) the CIM bevel gears are a bored out and key way broached "Pinion Shaft" as called on the website and the larger bevel gear is drilled out and broached to a 1/2" hex, so some modification will be needed but nothing beyond the range of a FIRST team with decent manufacturing capabilities. Working on getting everything lined up and working then I will go through and make it look pretty because we all know that counts
