Bullpup Sling-X-Bow: Front enhanced

Have added two bent metal rods to the front part, so the bands do not slip off, but stay on the rollers. This allows a much faster reloading.

Plus, it adds safety. In the unlikely event a roller breaks off, the rods (that are bolted onto the stirrup assembly) will prevent them from flying towards the shooter's face.

  2. Nice setup, this thing is going to look sweet with some paint.

  3. I like that slot, the bands were slipping in your video.
    I hope that allows for some much heavier bands now.
    By the way what the fastest you've shot (ft/s) with a portable slingshot/crossbow weapon?

  7. Simple, efficient, and effective. Typical of you. Well done.

  8. Great!!! Now you have space and strenghtness to add detechable arrow rest, something like on your genious "slingbow" - multiplex and 3 pieces of tubular rubber. I would do it :DDD Of course, trigger must be tuned somehow to make this beauty launch arrows...
    When we can expect finalized, full grown product?
    I'm so impatient :D
    Greetz!

  9. I am not wild about the arrow shooting business. Arrows are so darn expensive and prone to getting damaged or lost. But I may make a version that shoots bolts someday soon.

    The upcoming weekend will see the finalizing of this project.

  10. Ohh... with "this project" I refer to the ball shooting one, just to be clear.

    ReplyDelete
  11. Are you working on the tutorial too?

    ReplyDelete
  12. Yea, i know they are expensive. Instead, i make them from wood. I know that they brake very easely, and arent that precise, smooth and light but at least they are mine :D. Must ask you about different between bolt and arrow? Is it just in dimension, or have somthing to do with shape and aerodynamics?
    Thanks in advence!

    P.S. I'm wild in using both worlds on one single device :D

  13. Hey Joerg,

    Ivo checking in with a suggestion regarding cheek piece and scope mount. :)

  14. Ivo, could you verify that address as when I try it, it states it is not 'findable'.
    Thanks!

    ReplyDelete
  15. Jorg is there a way to make a scope? There kind of expensive for me.

    ReplyDelete
  16. Ivo, that is a cool picture!

    I wanted to try to make a fold away scope, on a swing arm. This way there is nothing in the way when I cock the weapon.

    Regarding scopes, I always make my own mounts, but I use a 5 Euro G36 surplus scope (ebay).

    These are just perfect for slingshot crossbows.

  17. Sweet addition to the bullpup, reminds me of the H. Love your designs, very creative. Hope you never stop.

    ReplyDelete
  18. If I knew German I could get one of those scopes... But hurricane is right scopes here aren't that cheap, not for good ones anyway.

    ReplyDelete
  19. so it won´t be much time to wait for the tutorial:D
    GREAT

  20. What do you think the max amount of bands that could hold is?

    ReplyDelete
  21. hmmm, i know they might be neccessary, but those bend screws are looking very clumsy. does not fit the overall look imo :(

    maybe a pure-metal version will solve it one day :)

    ReplyDelete
  22. Interesting Joerg, so you mean you want to build something that is similar to the EaoTech flip away mount? :)

    @antraxx

    Those bent rods are *not* load bearing components and merely function as means of stopping the band from slipping off the rollers at the end of the power stroke.

    A pure metal version would be sweet...especially if contained inside a square profile with a lever action or self retracting pulley based spanning mechanism. The bands repositioned in a vertical plane and retained with a double jaw latch(trigger) that doubles as an automatic pouch loader linked to a 100 (or more) round drum mag positioned under the barrel/track like on a bison sub-machine gun.

    Lol, I'm just messin' :)))

    Good luck Joerg, let me know if you need help with the forum...I've spent countless hours on the support forum.

  23. I think when I make one I'm going to put a sheet of ply wood that connects the rollers and the bands attachment metal all together so the bands don't slip and so there's extra support for everything. What do you guys think? any suggestions, cause I'd like to increase the number of bands to shoot some arrows or heavier bolts.

  24. O and side question does any one know what the fastest projectile is using theraband gold? I saw another guys video on youtube that was saying tb gold is to thick and is as fast as some of the other tb colors. Thoughts?

    ReplyDelete
  25. There are speed hunters who prefer shooting very lightweight balls as far as possible. That is fun, but the bands break so fast that you may get five shots from a band set. Impractibable for a serious weapon, which must be optimized for durability and projectile energy.

    For high speed records, gold is indeed a bit too thick. Black or blue works better. But for a serious weapon, gold is really nice.

    Rubber based weapons max out the shot energy with heavy bullets. 20 to 25 mm steel or 28 to 22 mm lead do that job for my handheld crossbows (cannons are different, of course).

  26. if you made that stirruo outa steel you culd serrated the front edge and there you have a wicked bayonet style setup...

    ReplyDelete
  27. From the photo, it should add some strength to the foot strip as well, I would think.

    ReplyDelete
  28. It pretty much stabilizes the entire setup.

    ReplyDelete
  29. Great!Now the rubber wont fall of every time.

    ReplyDelete
  30. I like the information about the bands and speed, I was wondering that for a long time!

  31. The rilfe. That's legal for Europeans ;P

    ReplyDelete
  32. You made a safety modification, safety is very important if not the most important imo.

    ReplyDelete
  33. will you be doing a video on it again?

    ReplyDelete
  34. How much Euro you've need for the materials incl.camou-painting??
