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 substantially straight handle portion and a substantially straight neck portion which are integral with each other and arranged so as to define an included angle therebetween. With the putter and shaft defined, the front-to-rear and end-to-end center of gravity cutting planes are accurately determined as well as their line intersection. The point of attachment for the shaft to the head is then determined so that the longitudinal axis of the handle portion of the shaft passes through the line intersection of the two center of gravity cutting planes. Once the shaft is joined to the head with a slow-setting adhesive, the putter is set on a very flat and level test bed 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 relative to the head until a true balance is achieved as determined by the test bed.
