[expand]The handle (riser) was fashioned first, providing foundation for limb attachment. The central section of wood blank was carved to comfortable grip shape, fitted with horn plates if design required, and prepared for limb integration. The handle’s precise dimensions and angles determined bow’s final geometry—even slight variations in handle angle translated to dramatic changes in limb behavior. The master bowyer had templates and measurements accumulated through experience, but final adjustments required judgment and subtle hand-eye coordination distinguishing competent craftsman from true master.
The limb cores were shaped from seasoned wood, carved to precise cross-sections and taper patterns. The limbs were not uniform rectangles but complex curved profiles whose thickness and width varied along length, each variation affecting stress distribution and performance characteristics. The bowyer worked slowly, removing wood incrementally, constantly checking symmetry between left and right limbs, ensuring proper flex patterns, achieving optimal mass distribution. The goal was limbs that bent evenly along their length (except near handle), storing maximum energy while remaining light enough for rapid casting.
The horn belly was applied in sections carefully fitted to wood core’s contours. The horn pieces were heated to make them pliable, bent to match curves, thinned to required thickness, and finally glued to wood with fish glue applied liberally. The clamping pressure was crucial—insufficient pressure left voids where glue couldn’t bond, excessive pressure squeezed out too much glue creating weak joints. The bowyer used ingenious clamping systems: cord bindings, weighted pressure points, specialized jigs—whatever achieved uniform pressure distributing loads properly.
The reflexing created bow’s characteristic backward curve. While glue cured, the bow was held in extreme backward flex—opposite to strung position—sometimes for months. This pre-stressed the materials, creating energy storage even in unstrung configuration. The reflexed bow required more force to string but delivered dramatically higher arrow velocity and greater range. The extreme reflex also caused problems: the bow fought archer during draw, the limbs wanted to twist or deform, and improperly reflexed bows could fail catastrophically. The balance between maximum performance and reliable safety was master bowyer’s art.
The sinew backing proceeded through many applications. Each layer of glue-saturated sinew fibers was applied thinly, allowed to dry completely (requiring days or weeks depending on humidity), then next layer added. The process repeated perhaps ten to twenty times, building sinew thickness gradually, allowing each layer to bond thoroughly with previous layers and underlying wood. The rushed application caused delamination—layers separating, sinew pulling away from wood, catastrophic failure. The patience was essential, the wait frustrating, but the result was sinew backing integrated completely with bow structure.
The curing consumed many months. After final sinew application and birch bark wrapping, the bow was left undisturbed in controlled environment—not too dry (causing cracking), not too humid (preventing proper glue cure), stable temperature avoiding thermal stress. The materials gradually reached equilibrium, internal stresses distributed evenly, glue achieved maximum strength, and composite structure became unified whole rather than separate components glued together. The waiting tested bowyer’s and customer’s patience, but hurrying this stage produced bows that failed within weeks or months rather than performing reliably for years.
