Abstract
A method of manufacturing a golf putter with a true balance includes the steps of designing or selecting a particular shape and style of putter head and then providing a putter shaft with a longitudinal axis and a neck portion which is integral with the shaft. With the putter head defined, the front-to-rear and toe-to-heel center of gravity cutting planes are accurately deterrnined. The point of attachment for the shaft into the top surface of the putter head via the neck portion is then selected and a plurality of bends in the neck are derived and made so that the longitudinal axis of the shaft passes through the front-to-rear center of gravity cutting plane. The intersection location on the top surface is between the toe of the putter head and the toe-to-heel center of gravity cutting plane. Once the shaft is joined to the head via the neck portion with a slow-setting adhesive, the putter is set on a flat, horizontal surface in order to test to see if there is any turning or rotation. If there is some slight turning or rotation of the putter head, a fine adjustment is made by rotating the shaft and neck portion relative to the head until a true balance is achieved.
