    Dacron B50 Stretch

    Post by Stonedog on Sat Jun 20, 2015 9:27 am

    I have a SB113 prod, #200.  Per Gary at SB, the string length for this prod is 26.5

    I have made a lot of bow strings and that isn't the issue.

    Dacron will stretch....quite a lot.

    What are your thoughts on making the string 24.5" long and pre-stretch it?

    Stone; For no more than Dacron costs,I would layup the string you mention. I have my setup with a boat winch and scale on one end. Any way stretch it out and see what happens. Won't cost more than a buck . You don't have to serve it. I use the more modern stuff 8125 BCY. I stretch that to 350#. Once made it does not move,period.This stuff more more like a wire when done.I use 20 strands=10 loops.

    I have a 3 spools of B50, so I'll go with that....Ill make a few strings and hang them up with an attached 25# weight and let it go for a few days and see what happens....I'll start with a 25" string as B50 tends to stretch about 1.5"...

    I've always used a Flemish with a bowyer's knot on my longbows....but a crossbow is a bit of a different animal....I do know how to make an endless loop string and serve.  I'll just set up a jig with adjustable lengths if need be!  THANKS!

    Stone, I don't know what your doing, I maybe get 1/4" stretch with the endless loop. That's nothing, and can be taken up  with a few twist.
