I am not an avid archer but I do shoot the odd target arrow. This bow was more of a fun and curiosity project. It is made from an old pair of downhill skis. For this particular bow I used the hind section of the ski. It is thicker and delivers more draw. I have not tested it yet but I can tell that the draw is in the 50 lbs range. After removing the bindings simply cut with a hacksaw to the length you wish and also cut the very tail end . Now you have an entry point at both ends without having to worry about hitting any metal. Should you decide to use the forward part of the ski for a re-curve bow the same procedure applies. Simply cut and inch off the very tip and go in with the band saw. As to how to decide for the width and length I simply clamped the two risers to a piece of 2×2x12 piece of wood and then tied the ends down as if you where stringing up the bow. This gives you an estimate and a feeling for the finished bow. The Bow handle design I got on line but you could easily design your own.
