Scare Joint





P until the 1890's, the golf club head was affixed to the shaft using a 4-6" taper on the head glued to a matching taper on the end of the shaft. Woodworkers know this joint as a scarf joint, while Scottish golf clubmakers call it a "scare joint". Besides golf, connecting two pieces of wood with adjoining tapered ends has many applications.




A simple scarf joint can be used to connect mouldings, siding, boat masts, etc.

An angled scarf can be used to attach the headstock of a guitar to the neck.
Simple scarf joints are connected together with opposing angled cuts, then glued and may use some sort of external buttressing. More complex scarf joints can use interlocking arrangements to provide more gluing surface and stability.

For hundreds of years, a simple scare joint was used for golf clubs. The year 1891 marked the gradual disappearance of the scare joint when Robert Anderson patented the socket neck. Since 1904, the majority of woods have been attached with the socket method where the shaft bores through a hole in the clubhead. The socket design is easier to manufacture. Traditionalists continued to use the scared neck design claiming better feel and tempo. The great Harry Vardon played all of his competitive rounds with the 'scare', and Walter Hagen won his fourth Open Championship in 1929 at Muirfield with one, the last major victory for the 'scared'. In his 1906 The Complete Golfer, Vardon makes a convincing argument for the continued use of the scared neck versus the socket neck:

The scared joint typically ranges from 4-6"

The length and angle of the scare should be the same for the shaft and clubhead neck
The angle can be adjusted surprisingly well with the plane and your eye.


While it may appear that the shaft is connected to the clubhead on this view, this is actually an aerial view with the clubhead above the shaft in preparation for pencil marking the correct angle for the shaft scare using the clubhead scare as a guide.
The taper follows the pencil line which is faintly seen. 

Both ends of the planed surface should end in points.
The grain of the shaft should run side to side rather than front to back
The shaft and neck tapers for the scare joint don't quite match on the club on the
left ruining the smooth transition between the shaft and the clubhead. 
The shaft and neck are more in line on the right.
Occasionally, a clubhead would be attached off line to change the lie of the club.

Traditionalists used string to clamp the scare joint while the glue dried.
I prefer clamps.

Ensure that the grain runs in line with the neck
