Fancy Schmancy Wheels

[Madison]

I've been playing around with Inventor over the last two weeks while simultaneously experimenting with some more unique ideas for drivetrains. Thus far, I've been using Ed Sparks' models of the 8" diameter wheelchair wheels, but I don't like the solutions I've found for mating them with sprockets. Also, I wouldn't mind something with a bit better traction.

So, I thought that we could design and build our own wheels this season - as I've seen lots of other teams do this. My question, though, is how do you do it?

This is what I had in mind, and I'll add Brecoflex belting to the outside, in theory.

But, how would I make it? What machinery would we use? It looks like we'll have access to anything I can imagine this season, including several CNC mills, CNC lathes, CNC punches and CNC sheet metal bender-things.

Any ideas? Some help? My bling-bling quotient is severely lacking.
