ABSTRACT:
A ski having an outer structure made of high strength steel. There is an upper steel sheet having a U-shaped cross-sectional configuration and a lower planar steel sheet. A wood core is positioned between and bonded to the upper and lower steel sheets. Two steel edge members have inwardly and laterally extending flanges which are bonded to the lower steel sheet, and a running surface member is bonded to the lower surface of the lower steel sheet. In the method of the present invention, the lower steel sheet, the running surface member and the edge members are placed in a receiving area defined by a fixture having two side rails, with the rails aligning these components. The core and the upper sheet are placed onto the lower steel sheet, with the edge members having alignment surfaces locating the components relative to one another. This forms a prebonded assembly which is later placed in a laminating fixture to form the finished ski.
