ABSTRACT:
The device for determining the center of gravity of an object measures the moments of the object (e.g., golf club head, or other irregularly shaped object) as it is positioned in three mutually orthogonal axes. As the weight of the object is known, the moments may be divided by the weight to determine the precise arm from the scale to the center of gravity of the object. A line is marked across the exterior surface of the object along each orthogonal axis, with the intersection of the lines defining the center of gravity of the object. A programmable electronic scale is preferably used, but other mechanical and electronic scales may be used as well. The knowledge of the precise location of the center of gravity of the object enables a technician to add or remove weight in precise amounts and locations to adjust the center of gravity precisely.
