In making a pair of skis, select two strips of Norway pine free
from knots, 1 in. thick, 4 in. wide and 7 or 8 ft. long. Try to procure as fine and straight a grain as possible. The pieces are dressed thin at both ends leaving about 1 ft. in the center the full thickness of 1 in., and gradually thinning to a scant 1/2 in. at the ends. One end of each piece is tapered to a point beginning 12 in. from the end. A groove is cut on the under side, about 1/4 in. wide and 1/8 in. deep, and running almost the full length of the ski. This will make it track straight and tends to prevent side slipping. The shape of each piece for a ski, as it appears before bending, is shown in Fig. 1. The pointed end of each piece is placed in boiling water for at least 1 hour, after which the pieces are ready for bending. The bend is made on an ordinary stepladder. The pointed ends are stuck under the back of one step and the other end securely tied to the ladder, as shown in Fig. 2. They should remain tied to the ladder 48 hours in a moderate temperature, after which they will hold their shape permanently. The two straps, Fig. 3, are nailed an a little forward of the center of gravity so that when the foot is lifted, the front [Illustration: Fig. 1, Fig. 2, Fig. 3 -- Forming the Skis] of the ski will be raised. Tack on a piece of sheepskin or deer hide where the foot rests, Fig. 4. The best finish for skis is boiled linseed oil. After two or three |
