ABSTRACT:
A perimeter weighted hollow golfing iron having a foam core with an effective hitting area concentrated toward the center of moments is disclosed. The weight of the club is concentrated at the perimeter to provide for the center of moments and proximate effective hitting area over the core. The club is formed from an investment casting having a cavity and is made from a method whereby the club is originally cast with a tapered core which is later withdrawn. Thereafter, an end plate is implaced over the cavity and welded thereto with an opening for insertion of the foam with an epoxy plug filling the opening of the plate. An effective hitting area is established by means of a club holder having a transducer so that impacts through an impact device against the club face can be sensed by the transducer to provide signals to an output such as a CRT, digital or analog readout or oscilloscope.
