    Old stock new weapon

    Post by Jacobasims on Tue Jan 01, 2013 3:50 pm

    Greetings all in the new year from the southern end of the UK
    A long while ago a family friend gave me a bike inner tube powered crossbow, this however broke before i used it and i decided i wanted to change to a more traditional crossbow, but i would like to use the original stock/tiller as he hand made it himself, having absolutely no experience with crossbows and wanting to do credit to his work i thought i would seek the help of people with more experience in the area of crossbows.
    to cut a long story short:
    What do i do about a prod? i have been thinking about buying one online
    is there a compact trigger design i can use in order to avoid altering the stock too much?(or is that lost cause)
    Many thanks if you can help me in any way.

    You might look at the Alchem web-site under supplies and accessories and go to crossbow components and look at the "notch lock " design under free plans.

    from the looks of the holes it seems the maker used the receiver plate and bolt from a latch used in the center of french doors. but in this case it would have the pin retracting to release the string instead of pushing the string up and over a notch. you could definitely use a notch lock without changing much.

    a roller nut may also work, but you would have to get creative to fit in the trigger parts under and behind it with the original trigger slot sitting so far back.

    Yep. I'd go with a notch lock. Simple and inexpensive and pretty effective.

    You can buy "replacement" prods off the internet pretty inexpensively. IIWY I'd look at the 80# fiberglass prods rather than the metal 50# prods. My current build uses an metal 50# prod but it is V shaped rather than flat and made shaping the prod socket much more challenging.

    That is a very nicely carved stock, and I can see why you would want to do something with it. I'm concerned that there may not be enough timber up front to support any but the lightest of target prods, however- it looks quite slender.

    The trigger is now going to be a variation of the Alchem notch lock trigger design so thank you for the advice
    The thickness was also a concern that i had, but the friend (chap called Tom) informed me it was a wood called Keroin, or some other variant on the spelling, and apparently this is quite strong stuff.
    The depth of the stock is 50mm where the trigger holes have been drilled at its narrowest, which is just before the end, it is 32mm. The whole thing is about 42mm wide. The distance from end to trigger holes is 19". If that information means much to you in terms of strength for the prod/bow, any tips would be much appreciated.
