Adapting the technique and materials is expected. I was hoping the kit might get me closer in terms of flex and usability. I have deconstructed a few pair of wood core skis and will take apart a few more when I find them. The cores are not solid in the kick zone camber, essentially the riser of a bow except they need to flex in order to set the kick wax onto the snow and pop back up to release it. They are vertically laminated with 1/16" veneers set about 1/16" apart. The front and rear of the ski is laminated just like a bow with a tapered veneer of wood on top of the camber and another beneath. There is also a layer of glass as a topsheet and a plastic P-TEX, sintered UHMWP (ultra high molecular weight polyethylene) base to absorb the glide wax and provide a better sliding surface for the snow.
