Claims3
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.

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.
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.
