ABSTRACT:
A method of producing a fiber reinforced plastic billiard cue which includes a tip end portion and a butted portion by forming an open-ended tubular tube of fiber reinforced plastic; securing joining devices in one open end of the tubular tube; placing the tubular tube in a cavity of a mold corresponding substantially to the size and shape desired of the billiard cue; heating the mold under a predetermined temperature for curing the tubular tube; applying compressed gas through the other open end of the tubular tube to force the shell thereof into contact with the inner surface of the cavity of the mold; and releasing the compressed gas from the open end of the tubular tube.
