Bowstring Specifications: We show the approximate ft/lb. so stringmakers can get an idea of how many finished strings can be built from a spool. Due to variables in the manufacturing process, we cannot guarantee exact specifications.
Breaking Strengths: We no longer publish breaking strengths because discrepancies occur, due to different test methods. We will provide minimum breaking strength information upon request. It should be noted that all modern materials far exceed the strength required to perform satisfactorily as a bowstring material.
Bowstring Diameter / Recommended number of strands: All bowstring material is relatively flat in a single strand, so it is not appropriate to publish a diameter of the individual strand. The important issue is how many strands are required to give a satisfactory nock fit, which is what the above recommendations show. These numbers can vary according to nock type / size and personal preference. Recommended strands are for typical modern compound bows. Plus or minus two strands is normal.
BCY manufactures and supplies products in accordance with these specifications. If used correctly, the material will serve the purpose for which it was intended- a bowstring or as a serving material. All products we manufacture are extensively tested. We offer a full range of material for the archery market. There are many variables which can significantly effect performance of the bowstring material. Some examples include: Number of strands and/or of twists, type of serving material, tightness of serving material, width of cam grooves on bow, amount of lubrication, type of release, condition of cam wheel, yoke system on cables, degree of string maintenance. As BCY cannot control these variables, BCY cannot accept responsibility for problems arising from strings, cables or servings.
