    Pump Action Slingshot

    Post by JoergS on Mon Oct 10, 2011 3:34 am

    A true repeating slingshot crossbow was always something I knew I had to make one day. Lots of problems to be solved. How do you deal with the band twisting? How do you cleanly line up the "pouch" every time? How do you feed a ball into the pouch without jamming?

    Now I have done it - the first functional repeating slingshot crossbow is reality. It "fires" 20 mm (.79") steel balls.

    The weapon can be loaded with 20 "rounds" within just a few seconds. Then, a simple racking action feeds a round into the chamber and cocks the bands.

    The weapon is used here to smash eight glass bottles, which is done in one uncut passage with just six shots:

    PUMP ACTION SLINGSHOT

    Joerg, thats pretty cool.Are you able to share with us a drawing to show how the reload & trigger mechanism works. Being a former lawyer I don't like reinventing wheels, rather I prefer to follow precedents and modify as required.

    Hi JoergS.
    The pump I think is my fav (aside from the inswinger slingshot LOL) so far to date, but I did enjoy the humungous one used to shoot up an old car! It was a hoot to see you on the Discovery Channel Daily Planet show. Thanks for showing an in-swinger torsion.

    I look forward to see what stuff you will make next.

    Do you sell plans? I would really like to build one of these. We have problems with racoons and I would like to use this as a deterent/terminator. I live in a rural but built up area so I cannot use a powerful crossbow for fear of hitting a house. I think the sling shot would work well. Especially if I used lead balls which would ricochet very little. Please let me know.

    Thanks, Richard

    Richard, Joerg has a whole forum dedicated to slingshots. He did a few topics where he showed how it works...maybe it's worth a look. Smile

    http://theslingshotforum.forumotion.com/search?mode=searchbox&search_keywords=pump&show_results=topics

    Also there are plenty other great builds. Very Happy

    As for pest control, please be careful...any weapon is dangerous - any way you look at it.

    Regards,

    Ivo

    Thanks Ivo. I agree with your caution to be careful. I plan on experimenting with elastic band draw weights etc. If I don't go that route I will use a crossbow on which I can change the bows with varying draw weights and use a low draw weight on the varmints. Yours,Richard
