ABSTRACT:
A method of configuring a stepped, cylindrical golf club shaft to achieve an optimum shaft impact angle is diclosed. A predetermined portion in the middle of the shaft is selected as are the number of steps to be used, the wall thickness of each step and the outer diameter. For each configuration which has the selected number of steps the deflection at a predetermined point is calculated when a load is applied at another point. For those deflections which fall within a desired predetermined range of deflections, the slope of the bending angle of the shaft is calculated at the point of deflection. A configuration is then selected which has a desired slope and a golf club shaft is made with the middle portion configured to provide the desired bending angle. Specific configurations for maximum bending angle are provided for both wood-type and iron-type golf clubs.
