Project: Making a crossbow from an old compound bow

I still have my Razor Edge compound bow. Not a bad weapon, but ever since my Liberty 1 arrived, it really only caught dust.

So I had this idea to use it as a part for a home made slingshot crossbow, much like the medieval style rubber powered model I am so happy with.

Took a whole afternoon, but it is now very functional. Medieval style trigger and rolling nut meets modern compound technology! The low letoff (15%) allow very easy trigger pull weights, making the weapon very accurate.



It shoots very well, but it is very ungainly to look at... still. Will make it nicer tomorrow! A video is called for, too.

  1. I've wondered when you would combine rubber and tensioned wood to utilize the potential of both. Good on you. I look forward to the video. Only, is that an arrow I see? Will it/ Can it shoot ball ammo also? All the best! (first again in posting-- amazing!)

  2. Did you attach the bow to the plywood using bolts? (no pun intended)

  3. Hallo Jörg,
    ich arbeite an einem ähnlichen Teil, habe aber noch ein Problem mit dem "Abzug". Kannst du vielleicht ein größeres pic von dem Bereich einstellen. Bei dir funktioniert das ja sehr gut.
    Viele Grüße aus dem Hunsrück.

  7. Can't wait for the video! I'd like to see a comparison to the liberty 1

  8. Yes, I used bolts. Just the standard attachment holes for the original bow sight and arrow rest, the bow is unchanged and can be dismounted easily.

    I already compared the Razor Edge with my Liberty 1, here:

  9. I misunderstood earlier. I had thought you had incorporated rubber instead of the 'string' of the original compound bow. So we wind up with a compound crossbow instead. Not as innovative as I originally believed but it will be nice to see nonetheless. (also I wasn't first afterall.) :)

  10. Well, I want to convert it to shoot balls in order to compare it with my rubber powered "version".

  11. huh, that sounds like an interesting project :-D

  12. Thanks, Joerg please compare it when finished with sling X bow i was amazed with power reaching energy of .22 Long!!! Btw very nice

  13. @stipe: Well, this time I hope to exceed the energy of a 7,92 x 51 (NATO). Wish me luck!

  14. Forgive me for correcting you, but the caliber you mentioned is not the NATO round (7,62x51). The one you refer to (7,92x51) is the old WW2 German Sturmgewehr round. But either have bunches of power and it will be interesting to see. All the best!

  15. Ah, I stand corrected. Of course you are right.

  16. That's cool:)
    Will be nice to see you shoot with it:)

  17. After watching the TV show The Walking Dead, my respect for the crossbow has increased one hundred times! The crossbow is silent, waterproof, with reusable ammo. Perfect for a Zombie-Apocalypse!

  22. So the old bow got a new way to use:D
    Its not not that good to look at
    but i think you will solve that!

    ReplyDelete
  23. that is one way to use an old bow =)

  24. That's a very long draw. Be interesting to compare the speed of the projectile to the conventional shooting style.
