ABSTRACT:
A template for weighting and placement of finger holes in a bowling ball has a meridian plane indicator and an angular indicator. The meridian indicator includes a scale which determines the distance between placements of finger holes and a thumb hole for bowling balls. A second scale is on the angular indicator to determine placement of a weighted center of gravity with respect to a bowling ball pin. The angular indicator is positioned with respect to the meridian plane indicator such that the meridian plane indicator forms the supplementary plane of the angle indicating member.
