    Cheap/Easy Arrow Retention Spring

    Post by jaeger22 on Sat Jun 21, 2014 4:42 am

    To finish up my hammer trigger I only need to add a retention spring of some type. I remembered seeing somewhere, I think on this site, that you could make one from PVC pipe. That sounded a bit strange to me but I was curious so I gave it a try. And it worked great! cheers 
    So I thought I would share. 
    First I cut a section of 3/4" thin walled PVC pipe in half. Then I heated it with a heat gun and when it got soft, I clamped it between two boards and let it cool. Looking at the nice flat springy material the came out, no one would ever guess it came from a pipe.
    Here is a picture with the retention spring laid out:


    And here it is cut out, heated again and bent, and screwed to the lock.


    A quick few minutes with a sharpie turned it into this:



    My little test bed bow actually turned out to be quite a nice shooter. No power house but simple and a lot of fun to shoot. I am going to leave it alone now and built a couple of other "test beds" for my other new action designs.
    Too many fun things to experment with, not enough time! tongue

    Yes I use PVC myself although mine was from schedule 40 and I did not flatten the strip just heated and molded in a form.
