Abstract
A method for fabricating a bat for striking a ball. The bat has a tapered barrel and a tapered handle and is formed of at least two pieces. Each piece, in its barrel, has a recess formed in it of a length less than the length of the barrel and which is formed along a surface which will be in the interior of the bat. The recesses combine to form a void which is of such a volume that the bat will have a desired weight and which is positioned along the longitudinal axis of the bat so that the bat will have a desired center of gravity. The bat is constructed by weighing the separate pieces, determining the proper location along each piece where material is to be removed to form the recesses and to determine how much material is to be removed, removing the material and then assembling the pieces to form the bat.
