Abstract
A locator 20 for facilitating the location of the center of gravity of an object such as a golf club head 130 includes a balancing member 42 having a rod 88 extending in a first direction from the member and a threaded rod 100 extending from the member in a second direction opposite the first direction. An adjustable weight 94 is located on rod 88 and a holder 110 for supporting an adaptor 138 and club head 130 is located on a free end of rod 100. Adaptor 138 with club head 130 are positionable in at least three different positions on holder 110 representative of the 'X', 'Y' and 'Z' coordinates of the center of gravity of the club head. When club head 130 is located in each of the three positions, balancing member becomes unbalanced. By adjustment of weight 94 on rod 88, balancing member becomes balanced. Various distance measurements are taken and, by use of a moment-summing equation, unknown distances are determined to locate the 'X', 'Y ' and 'Z' coordinates of the center of gravity of club head 130.
