This invention relates to a head connecting device for golf clubs; particularly a cast iron head of a wooden golf club such as a driver, a baffy or a cleek, a creek. The object of this invention is to apply a setting part is included which inclines against the axis of the pipe between the head and the shaft allowing a face angle .alpha. of the hitting face of the head to be adjusted easily by changing the direction or the angle of the setting parts.

A method of treating a body to produce a wood like appearance. A treating material is created by combining urethane mixtures aged different periods of time, from as little as one day up to five days, respectively. The combined mixture is allowed to flow into a water bath to create a line stream. The body to be treated is immersed in the water bath in the path of the line stream, removed and then dried. The treating material adhering to the body creates a wood-like appearance.

In a device of the type of an Inchworm Translator as called by Burleigh Instruments, Inc., N.Y., an electromechanical driver for a shaft of the device comprises a plurality of electrostrictive layers stacked longitudinally of the driver with internal electrodes interposed. Preferably, each gripper or clamper for the shaft is of a like structure and comprises a pair of external electrodes on an outer peripheral surface thereof. More preferably, the gripper comprises either an electrically insulating and abrasion resistive or an electrically insulating and vibration damping film which defines a cylindrical inner peripheral surface of the gripper. The film is preferably divided into a plurality of film portions. The electrostrictive layers are preferably of a composition of a formula of (1-x)Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3.xPbTiO.sub.3 where x is about 0.35. The electrically insulating and abrasion resistive film may be of either a plastic or a ceramic material. The electrically insulating and vibration damping film may be of a ferrite composition having a logarithmic damping factor between 0.04 and 0.06.

A hollow metal golf club having a structure in which the club head has a body portion and a neck portion for attachment of a golf club handle shaft. The club head is similar in shape and size to conventional wood club heads. A metal cylinder has a socket to receive a shaft. It is supported inside the neck portion and body portion. The handle shaft is mounted by inserting it in the socket of the cylinder and fastening it there by suitable means. The bottom of the hollow club head has an opening covered by a removable plate.
