    String traps bolt to tiller when loosed

    Post by Celtic Archer on Tue Mar 27, 2018 8:18 am

    I build pinlock style crossbows. This one has an Alchem 70# steel prod and bow irons, 36 strand string, Halo serving, 2 fletch POC bolt, hardwood tiller. 

    When I pull the trigger of the spaned and loaded bow, the string jumps over the bolt and pins it to the tiller, damaging the serving and scratching and chipping the bolt. It also bends the spring clip.
    Your suggestions are very much appreciated?
    Thank you.

    Some possible fixes: first check to see how far your push-pin actually lifts the string.  If the pushpin goes higher than the bolt is, that could be your problem.  Second, check to see that your prod doesn't have a lot of forward pitch (possibly in an attempt to reduce string drag) Too much lift on the string will make it jump over the bolt.  Lastly, try fitting a much stiffer bolt-clip, or even a solid housing that will keep the string from jumping over the bolt.  One of those oughta fix your problem anyhow.  Geezer.
