ABSTRACT:
A method for forming a plastic composite bowling pin includes removing the surface skin of a foam core, mounting a plastic base ring on such core, and molding a relatively thick elastomer shell around the prepared core and the base ring so that the hardening of the shell interlocks the shell, core and base ring. A pin made by this method is easily refurbished by removing the base ring and part of the shell and re-molding the surface of the shell.
