ABSTRACT:
Golf clubs are dynamically tested and matched with other clubs by measuring and recording angular velocity and centrifugal force along the axis of a club shaft as the club is swung on an arcuate path in a manner closely duplicating an actual golfer's swing. The club handle is clamped to a linear slide carried by a rotary slide housing having an angle of inclination approximating the lie angle of a golf club during use. Adjustable power rotational drive means swings the club and centrifugal force developed at a given angular velocity of the club displaces the linear slide to activate associated hydraulic devices which measure and record centrifugal force along the club shaft axis in relation to angular velocity of the club. Club weights are then added or removed until the desired angular velocity and centrifugal pull are achieved.
