Tips for clamping a shaft in a vise | Hireko Golf Blog

Tips for clamping a shaft in a vise

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.

    Jeff,
    Please give me your thoughts on back weighting, counter balancing etc. I’ve developed a pretty good system to adjust a club a full 100 Swingweight points. Now the question is why? Do you accept Backweighting as viable? Do you have any system of application. When I discuss this with other technitions I get “the application is all in how it feels.” If I’m going to adjust someone from a D2 to a A2 I want a little more then feel to rely on.
    Please help!

    I have experimented with backweighting for some 15 years so I do see merit in certain circumstances. You need to remember that there have been patents in the past on this topic as well as current companies offering systems, such as Balanced Certified. If you have developed a system, you will need to do some due diligences and look into any existing patents and pending patents.
