ABSTRACT:
An improved core for creating wax patterns of golf club heads is disclosed herein. The core includes a center core piece and several outer core pieces removably coupled to the center core piece by magnets embedded in each of the core pieces. The core further includes a pneumatic release system, including a manifold, to easily separate the center core piece from the outer core pieces and expel the center core piece from a wax pattern, thereby eliminating the need to pry and pull pieces out with a tool, which could damage the wax pattern of the golf club head.
