The plan was to use some bicycle hubs to support the inner frame. Amazingly the hub is as wide as the batteries are tall, (on their side), and as high as the ev warrior.
On the center hub will be attached to the base, while the axle will be able to spin free. At the top of the hub will be another piece of uhmwpe. The uhmwpe will be supported by other bolts. At the top of the center axle, above the second piece of uhmwpe, will be the pulley from the motor, which will be attached to the shell somehow.
Since the axle is really thin (8mm), I was planning on using some ball transfer bearings at the edges of the base piece of uhmwpe. Then I looked up some prices for the ball transfers. I would need at least 4. The cheapest ones are $15 a piece, and I wouldn't like to use them because they are too small. The ones that I like are $45 .
Still, I think that some thrust bearings mounted in the base, which spin with the inside of the shell will prevent any large leverage forces from bending the center axle.
That is my hope , I just can't seem to find the time at the moment, I have assignments coming out my ears.
