ABSTRACT:
A golf club putter is constructed with a head having a high polar moment of inertia about its preferred ball striking point by forming the putter head body out of light weight material, such as aluminum, with relatively large heel and toe cavities. A predetermined mass of heavy material such as molten lead is poured into the cavities along with a small amount of uncured epoxy. At the temperature of molten lead, epoxy loses much of its viscosity and flows on the surface of the lead to fill voids caused by contraction of the lead. A thin cover preferably of a decorative material like polished brass then is bonded to a flange formed about each cavity by the epoxy to close each cavity.
