Apparatus and method of dynamic inertial balance for golf clubs

A dynamic inertial balancing system (10) uses a shaft (20) mounted to a base (16). A motor (46) or pulley system (42) imparts rotational torque on the shaft. A swing arm (18) is coupled to the shaft and moves through an arc in a horizontal plane in response to the rotational torque. A golf club is m...

Zusammenfassung:	A dynamic inertial balancing system (10) uses a shaft (20) mounted to a base (16). A motor (46) or pulley system (42) imparts rotational torque on the shaft. A swing arm (18) is coupled to the shaft and moves through an arc in a horizontal plane in response to the rotational torque. A golf club is mounted to the swing arm. A timer (38) records the time for the swing arm to traverse the arc. The system balances the golf clubs within a set by measuring their moments of inertia. Each golf club is placed on swing arm 18 and the time is measured for the each golf club to complete the swing arc. If torque is constant for all clubs, then by comparing the moments of inertia, i.e. by comparing the time for each club to complete the swing arc, the club set can be balanced.
