ABSTRACT:
A golf club head, particularly a putter, having an improved selectable weight and adjustable balance system. The head has an elongated threaded weight chamber extending from toe to heel. The chamber contains weights, preferably coins, and thrust/ friction washers which are captured and secured by opposing threaded end plugs. The amount of weights used and their collective effective center of gravity is adjustable by the user. The center of gravity or sweet spot is adjusted when the end plugs along with the captive weights and washers are rotated toward the toe or heel. When rotated toward each other, the end plugs produce a strong locking force on the entire weight assembly. The balance and sweet spot characteristics are also controlled by the strategic placement of weights within the chamber. The washers can also be used as spacers to aid weight distribution. When more weight separation is required, an optional compression spring is used between weights. By selecting the amount of weights deployed and by the strategic placement of the weights, many options of putter head weight and balance are available to the golfer.
