The bevel gear is the vex one and from the model it looks possible to bore it out to 1/2in and then broach a 1/2in hex into it which is what I am hoping for. If not I will need to rethink that portion.
The "gear" pattern at the top is currently meant to interface with an htd 5mm belt allowing the module to turn. I will be making some cuts within the next few days to see if it is possible to make a cog in house that will effectively mesh with such a belt using our resources at hand.
As for the encoders, motors, mounting, etc. those are all things that are yet to come. I have begun sketching some layouts for the other components but for the moment this is what I've accomplished these past two days.

If that's a belt pulley you should be fine with a ball end end mill actually.
If you bore out the bevel gears do some heavy load testing to be sure they won't fail. If the shaft fails before they do, that's a good thing.
Encoders always kill me actually. In particular, you may have to put the absolute encoder for rotating the module on the gearbox you use to turn it, rather than on the module itself, and compensate in code.
