Also, you may want more than just the two holes in the WCD block to mount the gearbox to the tube. Two more holes higher up on the gearbox would add a lot of strength.

The Cims are already removable. (although not very easily) I've considered making the gearbox removable, but I haven't come up with anything slick yet.

3) How do you plan on mounting the gearbox?

It weighs 1.9 lbs without motors and 10.5 with them according to inventor.
First stage is 12 to 54, second stage low is 24 to 60, and second stage high is 40 to 44.
It's mounted with the standard bearing block and the two bolts the are out to the sides.

The VEXpro ballshifter has a small aluminum shifting rod that tends to wear out. In this design, we would make out own out of steel for longevity.

That's just how I roll. If we're already going to be milling out the plates, why not optimize for the lowest weight reasonable?

This uses a simple one piece output shaft. Machinable on a manual mill and lathe.

Thanks for all the great responses! Keep it up!
