Thread: Advice/tips for DIY bowstring

Ages back I made a bowstring from dacron flyline backing line. Used white and orange line so it would look nice. Tied the untwisted line off against a hook on the wall, chucked the other end in a drill, then spun it while keeping it taught. Once it wouldn't spin anymore without balling up, I had someone grab the whole thing in the middle and walk it backwards forming a narrowing V until the two ends touched, then allowed the two halves to gently twist together into a rope. It takes a bit of work to avoid it balling up, but forms a beautiful even twist line. I can't remember the ratio of starting untwisted line length versus finished twisted length but I believe you need to start with something like 2.5x or 3x your finished length when you prep your line for twisting. Once it's twisted you then hang it with a weight on it to let it relax for a while before using it.
