Child of a Metal God

I considered that, but decided against it. I'm going to need brakes anyway, so I might as well use them. Making the pillar rotate would add a lot of complication and specialized machining. What really clinched it for me was the pain of coordinating every course correction with the person in the secondary drive position, who would also have to rotate. At the cost of an ATV differential, one extra chain drive linkage and a U-joint in the con-rod, I really think this is easier.
