ABSTRACT:
A composite ski is made by bonding a metal ski top to a molded ski body during the molding and curing of the body. The ski body is placed in the mold cavity of a two-part mold, and the metal top is movably supported on the other mold part. One end of the metal top is held by a spring-biased holding pin which permits the metal top to expand and contract relative to the mold part as the mold is heated and cooled while maintaining the metal top in alignment with the cavity.
