ABSTRACT:
A wax shell covered pre-formed core body is provided, the thickness of the wax shell corresponding to the desired thickness of the wall structure. A ceramic shell is formed about the wax shell. The wax shell is removed by melting the wax, thereby to form an opened gap between the ceramic shell and the core body. Molten metal is cast into the opened gap, thereby to form the wall structure extending about the core body and at the sole, while forming and maintaining port structure through the wall structure and spaced from the sole, and allowing the wall structure to solidify to form the head. The ceramic shell is removed from the wall structure, and the core body is removed from the interior of the solidified head, and via the port structure.
