Re: crossbow string.
- okay for starters to measure string for a cross bow is no different
than measuring for a long bow. or recurve for that matter. you go from nock to nock following the curvature. then if your going with a continuous loop. subtract 3 inches from that total.
It is going to be a thick string no matter what material or style. you use. But I have made a couple of strings for a Crossbow. I made it in continuous loop, but I made it out of Fast Flight, it strength is 2x over B50. it is a safety thing for me. If memory serves, I would have to say I made it continuous loop. I think I went 15 laps around the jig.
And get the serving designed for crossbow strings. It WILL set you back but again, SAFETY, SAFETY, SAFETY!!!!
