Abstract
A bat having an exterior shell is manufactured by placing the shell on an exterior portion of a barrel portion of a starting tube. Then the tube and the shell are simultaneously tapered to the desired bat shape. The simultaneous tapering is preferably accomplished via a swaging process. The barrel arid the shell are both preferably constructed of metal, such as aluminum. The simultaneous tapering of both ends of the shell retains the shell in place upon the bat while allowing longitudinal movement of a point on the shell relative to the barrel when the bat flexes upon striking a ball.
