Abstract:
A system and method for producing a bowling ball, where the thumb hole and finger holes in the bowling ball are angled to accurately match the anatomical requirements of the bowler's hand. The system includes a measuring jig assembly for obtaining data on where to drill finger holes in a bowling ball. The measuring jig assembly has holes for the thumb, the middle finger and the ring finger. The position of the thumb hole can be moved in a unique manner so that the thumb hole need not be located below the middle finger hole and the ring finger hole. Furthermore, the angle at which each of the holes enters the measuring jig assembly is adjustable across a range of motion that mimics that achievable by the tips of the thumb, middle finger and ring finger of a bowler. Accordingly, the holes can be adjusted to unique angles required by a particular bowler's hand anatomy. The data retrieved from the measuring jig assembly is then used to produce a bowling ball customized to a bowler's hand.
