Milling, waterjet, welding?

We have access to a CNC Milling Machine, Welding equipment, and a waterjet. Gotta love sponsors!

We are solely using WCProducts' Gears. We have a 14 T CIM gear going to a 45. From there, the Low gear is 15 T to 60 T. The High Gear is 30 T to 45 T.

Yes, the part that is visible is a 1/4" Plate. There is .25" of overlap between the 2x1 and the plate. Is that enough?

How would I get away with out running the chain below the chasis?

That is true, I will fix it in the next version of the battery holder.

I essentially copied 254 and the Holy Cow's electronics setup. We are not going to be predrilling holes into the bellypan, so if this setup does not work, we can find another way of mounting.

I would definitely love to use 7075 Aluminum drive shafts. Do you know where I can get 1/2" 7075 Aluminum Hex?

Worst case scenario, I could always have our machinists use a 4th-axis on the Mill to get that 1/2" Hex. (It's just always nicer if we can buy it premilled in the Hex configuration)

Thanks again for your help.
