One item that is taken for granted is clamping the shaft, whether it be to grip (or re-grip) the club or other repair orientated work. Before you clamp down on the shaft, please take note of this tip. The trend in the industry is to use very lightweight shafts, either steel or graphite. In order to achieve the lightweight nature of the shaft, the shaft walls are constructed thinner. As a result, the shafts are susceptible to cracking longitudinally down the length of the shaft. This is especially true of shafts that weigh less than 60 grams in graphite and 100 grams in steel.
In the event the shaft cracks due to excessive clamping pressure, the shaft is no longer under warranty. Gradually build up the clamping pressure so the shaft is “snug”. You may find that when clamping extremely lightweight shafts and do not wish to over-tighten, the shaft could slip from the vise clamp when trying to get the grip started. In those cases, it is better to clamp close to the tip. The tip end is generally thicker and less likely to crack as a result of too much pressure.
