Abstract
A golf club head and a method of tuning the golf club head. The golf club head includes a body having a front surface, a back surface, a heel end, a toe end, a sole extending between the lower portions of the heel and the toe ends, a top portion extending between the upper portions of the heel and toe ends, and a cavity. One or more magnets are mounted in the cavity such that their distance into the cavity can be adjusted. A detachable face plate having one or more magnets attached to a back surface of the detachable face plate is slidably mated with guides extending from the body. At least two of the magnets are positioned such that the north pole of the magnet in the cavity faces the north pole of a magnet attached to the back surface of the detachable face plate. A repulsive force between the north poles pushes the detachable face plate away from the body and into a stop coupled to the body. The strength of the repulsive force is adjusted by the distance between the magnets to provide a golfer with the desired face plate stiffness.
