Abstract
A bowling ball having an internal weight whose position along a spin axis is adjustable by operation of a drive means which in turn is operative to rotate a threaded nut sleeve that supports the weight. The rotation is about a threaded, non-rotatable weight shaft that extends along the spin axis. This threadably advances the nut sleeve and the weight along the length of the weight shaft, thereby altering the center of gravity and path of the ball after it is released by the bowler.
