  • Apparatus and method for producing shafts having preselected lengths and flexural properties
    Patent number: 5952580
    Abstract: A golf club shaft blank is clamped at its butt end and deformed at its tip end to establish the longitudinal deformation characteristics of the shaft blank. The shaft is repositioned relative to the clamp and then reclamped at a new location which, when deformed, has the desired longitudinal deformation characteristics. The shaft is sawed to the desired length by removing material from the butt end and the tip end of the shaft.
