Abstract
A set of wood golf clubs have wood club heads with substantially the same external shape. The vertical centers of gravity of the wood club heads are varied by setting the weight within the respective soles and the crowns, while keeping the total weight of the wood club heads substantially constant. The wood club heads have no integral hosel. The wood club shafts are attached to the wood club heads by providing a bore in the wood club head sized to receive the wood club shaft therein, and a threaded fastener that engages the wood club shaft to the wood club head, when the wood club shaft is inserted into the bore. The wood club heads are desirably cast to shape, using casting cores that provide for the shifting of weight between the soles and the crowns within the set.
