ABSTRACT:
A method of producing a baseball bat in which the barrel or hitting portion of the bat is molded from synthetic resin and is affixed to a wooden grip or handle portion. An apertured metal tube is fitted over the barrel portion and synthetic resins are foamed through the apertures to bind the metal tube to the barrel portion. The synthetic resin is further smoothed over the entire metal tube and barrel portion. Then, a winding of glass fibers or a stocking of knitted glass fibers may be wound or fitted over the metal tube and barrel portion and painted with a synthetic resin paint which is allowed to permeate the fibers. The synthetic resin may be urethane foam, and the metal duralumin, and the windings or knitted stocking may have a textured surface which will enhance the ability of the bat to prevent foul balls.
