ABSTRACT:
An improved bowling ball insert includes a generally cylindrical body and an interior cavity formed therein. The shape of such cavity is partially defined by a generally planar first surface, by a curved surface and by a generally planar second surface. The shape thereby imparted to the cavity generally resembles that of the distal portion of a human finger. To provide a tactile indication of correct insertion depth of a finger within the insert, the second surface includes at least one projection extending outwardly from the second surface. In a highly preferred finger insert, the width of the first surface is selected to generally correspond to that of bowler's tape which may be applied to adhere to the first surface. The relative positions of the first, second and curved surfaces are such that when a strip of bowler's tape is applied to the first surface, a finger inserted into the cavity is urged toward the second surface and the curved surface by such tape.
