    The Chu-Ko-Nu concept maxed out!

    Post by JoergS on Sun Apr 01, 2012 8:15 am



    It is now a reality - cost me 12 hours in the shop today. A full size version of my pencil shooter! You strap it on like a "monster dildo of death". :wink:

    In the pic, you see it next to the pencil shooter, it's tiny little brother. Gives you an idea about the dimension.

    Attached to your chest, you can draw it back in a rowing fashion. This allows really high draw weights, impossible with a handheld slingshot. This is the most dangerous and effective weapon I have ever build.

    45 kg (100 lbs) of a draw weight means it propels the 115 Gramm (a half pound) aluminum bolt, 15mm (0.59") diameter, with a 12mm (0.47") diameter steel tip to scary speeds. This uses my entire effective arm range! I see no way of making it even more powerful. It weighs about 4 kg (10 lb).

    The rubber is prestretched from 27 cm to about 90 cm.

    I call it the "Massacre Master" because that is what it can cause amongst Zombies - ten such monster bolts fired in under 10 seconds, easily. Short reloading time as you have both hands free. Easy aiming thanks to the long barrel.

    I say with pride that I managed to improve Zhuge Liang's repeating crossbow, and the way I did it would have worked back then (albeit with a normal bow instead of rubber). Can you imagine what a few hundred of these could have done in an ancient battle?

    No zombie is safe, and with that reloading speed, you will survive the coming appocolypse for certain.

    This is a very impressive weapon! Thanks so much for sharing it. You are an inspiration, sir.

    Strap and breast plate looks like a good way to brace it for shooting. I wonder if you could attach it to a tripod, bipod, monopod of sorts to help a bit with stabilizing for more accuracy? Just thoughts... It could almost be mounted as the old ballista was although it would make it more of a stationary weapon unless the bi/tri/monopod was light enough to quickly set up and tear down for mobility.

    Mr. Joerg, I know you have a copyright on everything, but would you mind if I took the name "monster dildo of death" and built this for a school project? ~ just joking.

    Really cool machine, sorta mix between a gastrophete and a chu-ko-nu (no idea how those two are spelled Razz )

    You have your own forum I hear, can you give me the link? I'm making a side panel with "friend forums" and want to add yours to it. Smile

    PS: By the way, I'm Ivo's brother. Nice to meet you Sir. Very Happy

    Antho, so the love for slingshots runs in the family? Smile

    My website www.slingshotchannel.com has the links to my forum and my blog. I know that Ivo probably would not have issues with it, but posting links to other forums is against the unwritten netiquette.

    Mr.JoergS,this repeating crossbow is not Chu-Ko-Nu style,but Chu-state repeating crossbow style. I guess this automation weapon was designed before 100 BC, much ealier before Zhu-Ge-Liang'S birth.
    Can you show us the trigger mechanisim and your design of this repeating crossbow? Thank you in advance, your chinese adorer.
    By the way, website like youtube is blocked in our country.
