Then, you can connect a standard circular shaft, and use a keyway or pin or dutch pin to secure the hex shaft to the circular shaft.

I understand the idea, but what kind of machinery would one need to insure that the hole would be dead-center? Would a standard drill press be OK for this?

I think we will buy .874" hex stock, and use it as a hub for the wheels, . . as in it just fits onto a standard smaller circular shaft, and is secured using cotter pins or something of that nature.

BTW: that airport picture is awesome! Did you try to ride on it (I know I would have)?
