EDIT: And which miter gears are those? They don't look like Vex ones.

Thanks for the kind words.
The weight is a little lower than I expected as well, considering the added complexity. I attribute the lower weight to the caster portion being smaller. It now fits into a 72 tooth 20 dp gear from VEX instead of an 84 tooth.
The top plate is 0.25'' thick so that the plate that the CIM mounts to can be attached to the side of it with 6 32 bolts.
Yes, the steering gear and the bottom gearbox plate have grooves milled in them for 0.25" delrin balls.
The first set of miter gears are 1 module, 20 tooth because they have 8mm bore, and they're a little smaller. The later ones, in the caster, are 20 tooth 20 dp, because my team has had success with them in the past. They are both made of steel, and from SDP-SI.
