Fig. 2 represents an unbraced bow showing the propor-tional dimensions of a target bow. This is superimposed withworking diagrams in the braced and full drawn positions. It will be noted that line AB is the over-all length of the bow.Line C is the mathematical center. It will be noted that theupper limb is 2 inches longer than the lower limb. The exactcenter or line C bisects the grip 1 inch below its upper edgeand 3 inches above its lower edge. By reason of this differencein the length of the limbs the bowyer has to so tiller the jobas to compensate for this difference. Therefore, when the bowis braced (strung), the distance from the string to the belly is3/8 inches greater in the upper limb area than in the lower.But, when the bow is fully drawn, the limbs are perfectlyequalized, or "come compass," to use an old English term.(Fig. 2, lines H and I.) |
