PURPOSE:To measure the stiffness, of golf club shafts accurately by erecting the golf club shaft perpendicularly on a balance, supporting its grip end by means of a chuck, applying pressure of specified quantity in perpendicular and reading the scale of the balance. CONSTITUTION:The height of a...
Golf club length fitting system A method and apparatus for prescribing overall club length for iron-type golf clubs for an individual player wherein the method comprises measuring the erect height (PH) of a player to be fitted, providing the player with a fitting ball ... DC Wood,AR Rothman...
Method of measuring the flexibility of a golf club shaft A method of measuring the frequency characteristics of a golf club shaft by taking measurements at a plurality of predetermined locations along the length of the shaft being measured. These measurements are used to determine the overall ......
To measure, press the sole of the club against the angle. Press the hosel flush against the bottom board. Measure club length. My Wilson C300 4 iron is spot on the 39-inch specification. MattWillGolf,mjr,MattFand12 others 15 Quote ...
[0009] The golf clubs are different in length and suppleness of shaft, weight, size and shape of head, the angle at which the shaft ends and the head begins (the lie), and the angle of the face of the club from the vertical (the loft). In the average, good players set there are...
The Influence of the Grip Acceleration on Club Head Rotation during a Golf Swing Golfers aim to hit the golf ball correctly and maximize its displacement. It is necessary to predict shaft movement during a golf swing via simulation in order to determine the appropriate shaft for each individual ...
Method of measuring the flexibility of a golf club shaft A method of measuring the frequency characteristics of a golf club shaft by taking measurements at a plurality of predetermined locations along the length of the shaft being measured.

A measurement apparatus primarily for use during the purchase of golf clubs for indicating angle modifications between head and shaft needed to assure zero angle between the sole and the underlying surface for a particular golfer. The apparatus comprises a club simulation member having a shaft and ...
The rotational axis J of the golf club head 20 is coincident with the axis of a golf club shaft. [0094] The three-dimensional coordinate value of each mark 21 given to the surface of the golf club head 20 in the above-described manner is read with a three-dimensional measuring device...
first signals. Each double beam device contains two separate beam detectors (3,7,11; 4,8,12) mounted at a separation constituting only a fraction of the measurement path's length. Each uses a narrow beam across the path detected on reflection from the object. 展开 ...
