Apparatus and method for tuning a golf shaft
View Patent ↗A method of making a golf club includes making a first determination of the location of the effective seam in a shaft and then more precisely locating the seam before attaching a golf club head with the face of the club head facing in a neutral direction.
1. Apparatus for locating the strongest point on a tubular golf club shaft, comprising:
a. a longitudinally elongated base;
b. a pair of supports for said tubular golf club shaft upstanding from said base and longitudinally spaced one from another; and
c. means connected to said tubular golf club shaft for selectably exerting downward force on the tubular golf club shaft residing rotatably on said supports at a position substantially mid-way between said supports while permitting rotary motion of said tubular golf club shaft on said supports.
2. A method for locating the strongest point on a golf club shaft, comprising:
a. supporting the shaft at two longitudinally separated locations and rotating the shaft as supported thereby; and
b. contacting the shaft in a direction transverse to that of the axis of the shaft with a downward force and a retractable gauge intermediate the locations during shaft rotation and detecting radial deviation of the shaft.
3. A method for locating the strongest point on a golf club shaft, comprising:
a. supporting the shaft at two longitudinally separated locations;
b. manually rotating the shaft at one of the two longitudinally separated locations;
c. contacting the shaft transversely to the axis of the shaft at a pre-determined position substantially intermediate the separated locations with a consistent downward force; and
d. detecting radial deviation of the contacted portion of the shaft during shaft rotation.
