Abstract:
A golf club head comprising:first and second separate parts having mating first and second mounting surfaces, respectively, to be joined together into a unitary one-piece golf club head;the first and second mounting surfaces of the first and second parts, respectively, having opposing surface portions, respectively, which lie in a plane of expansion of the first part with respect to the second part;opposing surface portions of the first mounting surface of the first part having a normal dimension larger than the corresponding dimension of opposing surface portions of the mounting surface of the second part;the opposing surface portions of one of the first and second parts defining an outward protecting step, and the opposing surface portions of the other of the first and second parts defining a recessed step complementary to the outward projecting step, the outward projecting step and the recessed step spaced inward of a periphery of the first and second parts; andan interference fit joining the first part to the second part by mating of the first and second mounting surfaces by expansion of the first part to the normal dimensional shape after contraction of the first part during cooling.
