Those holes are for the locking mechanism of the wheel nut. Usualy the locking mechanism is integrated in to the axle, but Williams can't do that becouse the axle is hollow, so they integrated 3 pins in to the wheel nut that, when the nut is thightened sufficiantly, lock in those holes.bhallg2k wrote:This is just gorgeous.

Anyone know if a rotating wheel can be used as a pump?
