Where would one get a block of aluminum that big? We are sponsored by caterpillar and are able to order material through their tool room, and off hand I'm pretty sure we couldn't get our hands on a block that big (regardless of price).

On another note even if this isn't a troll post (i'm pretty convinced it is however), it is a fun thought experiment on way out their ideas. Plus I wouldn't be surprised if a veteran team or two experiments this off season with a non circular wheel just to see what happens.
