Abstract

An apparatus for precisely and accurately measuring the loft and lie of a golf club, and a method of using such apparatus, is disclosed herein. The apparatus includes a clamp assembly powered by a pressure unit to immobilize the head of a golf club, a scoreline measurement unit to capture scoreline angle information, loft and lie measurement arrays that can be moved along horizontal y and x axes to capture loft and lie angle information of the golf club shaft, and a computer with an algorithm that uses information captured by the scoreline measurement unit and loft and lie measurement arrays to calculate final loft and lie angle values that are accurate within +/−0.125°.

Claims3

Dependent claims

A method of measuring a loft angle and lie angle of a golf club having a head and a shaft, the method comprising:

clamping the head within a measurement apparatus;
centering the shaft within a sensor display of the measurement apparatus;
calculating an angle of scorelines on a face with one or more scoreline sensors, lights, and lenses;
calculating preliminary loft and lie angles of the shaft with one or more loft and lie lenses, loft and lie lights, and loft and lie sensors;
algorithmically calculating final loft and lie angles of the golf club using the scoreline angle and preliminary loft and lie angles;
increasing a pressure within a tank of the measurement apparatus;
increasing a pressure on the golf club head within a clamping apparatus using the increased pressure;
and
bending the club.
