A machine and method for conveniently dynamically balancing heavy rotational members such as large vehicle wheels is disclosed. The machine employs a horizontal rotatable shaft that is movable vertically so as to align and engage the center of the member as it stands vertically in the ground. Thereafter the shaft is raised vertically until the member clears the ground and is rotatable for balancing. In preferred embodiments the balancing mechanism is manually powered and detachable from the machine\s base for transport and the base is constructed with its vertical member angled so as to preload and stress the base by the weight of the member and eliminate play in the base. The machine offers portability and transport advantages.
