| 摘要 | Method of producing variety of golf club shafts from universal blank shaft of given length includes steps of determining actual natural frequency of blank shaft. Selected amounts of shaft length are then removed from both tip and butt end portions of blank in correlation with natural frequency of blank. Total amount removed from blank solely depends upon length of shaft desired while selected amounts removed from tip and butt end portions of blank solely depend upon natural frequency of shaft desired. As proportional amount removed from tip portion increases, frequency of produced shaft also increases. Conversely, as proportional amount removed from tip portion decreases, frequency of produced shaft also decreases. | ||||||
