Quick Answer
Bow string material is crucial for a bow's performance, durability, and overall effectiveness in hunting or self-defense. A well-made string can withstand repeated use and harsh weather conditions, while a subpar string can cause damage to the bow and even lead to accidents. A bow's string is its weakest link, and choosing the right material can make a significant difference.
Choosing the Right Material
When selecting a bow string material, consider the type of use, the environment, and personal preference. Traditionally, natural fibers like plant-based sinew, animal gut, or rawhide have been used for bow strings. These materials offer excellent durability and can be made from locally sourced materials. For example, sinew is a popular choice for its strength and suppleness, with a recommended thickness of 1/8 inch (3-4 mm) and a maximum stretch of 20-25%.
Preparing the String Material
To prepare sinew for bow string making, clean and dry the material thoroughly. Then, stretch and twist the sinew to align the fibers, which can be done using a specialized tool or a wooden dowel. Apply a small amount of natural adhesive, such as beeswax or plant resin, to the twisted sinew to hold it in place. This step is crucial in creating a strong and consistent string.
String Making Techniques
To tiller the string, use a combination of twisting and stretching to achieve the desired shape and tension. The tiller should be approximately 10-15% longer than the bow’s draw length. For a sinew string, apply a minimum of 10 pounds (4.5 kg) of tension to ensure adequate stability. Regularly inspect and maintain the string to prevent wear and tear, and consider re-stringing the bow every 6-12 months or after 100-200 shots.
