The Role of Epoxy in Installing Graphite Shafts

Perhaps the most important part of club building is correctly bonding the shaft with the club head. However, some clubmakers make the mistake of applying epoxy to the tip of the shaft and then jamming the shaft into the club head. In doing this the epoxy is forced to the bottom of the shaft, leaving an empty countersunk chamber between the ferrule and the club head (see drawing).

The purpose of filling the countersunk chamber with epoxy is to create a strong bond. However, it is crucial to remember that by jamming the shaft into the head, the purpose of using epoxy is defeated, leaving the possibility that the shaft will eventually break after repeated use. In other words, with the epoxy forced to the bottom of the shaft, it becomes almost useless.

In order to ensure that there is a solid bond between shaft and head, we recommend that the epoxy-covered tip is slowly twisted into the hosel. This allows time for the epoxy to be distributed evenly without being forced up or down the club head. The epoxy then settles in the chamber, creating the necessary bond between the tip and head.

In addition, it is important to carefully apply epoxy when putting weight pins in the bottom of the shaft. The epoxy should be applied to both the weight pin and the hole in the shaft in order to create the necessary bond between the pin and shaft.
