Quick Answer
Temperature changes can significantly impact the performance of a bow, with temperatures below freezing causing reduced draw weight and temperature fluctuations affecting string stability.
Temperature and Stave Selection
When selecting a stave for primitive bow making, it’s essential to consider the temperature range the bow will be used in. A hardwood stave like Osage orange or hawthorn is more stable in cold temperatures, while a softwood stave like Eastern white pine is more flexible and suitable for warmer temperatures. A stave with a high moisture content is more prone to warping and should be avoided.
Temperature and Bow Performance
Temperature changes can cause a bow to lose its shape and affect its performance. In cold temperatures, the wood contracts, reducing the bow’s draw weight and making it more difficult to draw. Conversely, in warm temperatures, the wood expands, causing the bow to lose its shape and become less efficient. To mitigate this effect, it’s essential to maintain a consistent temperature range for the bow and to use a consistent tillering technique to ensure the bow’s limbs are evenly tapered.
Temperature and String Stability
Temperature fluctuations can also affect string stability, causing the bowstring to stretch or shrink. To minimize this effect, it’s essential to use a consistent string material and to adjust the bowstring’s tension accordingly. A bowstring with a high tensile strength, such as one made from natural sinew, is more resistant to temperature fluctuations and can maintain its stability in a wider temperature range. When adjusting the bowstring’s tension, it’s essential to do so in small increments to avoid over-tightening the string.
