    I saw Joerg's scorpion and thought if it was built the same way a traditional Roman scorpion was built but using spear gun rubber tubing you could get one heck of a bolt thrower!<br><br>Unfortunately, I have no workshop and no time to build one. But if anyone else wants a go at it then please do! I would love to see the results!!!

    The thing is, rubber won't work the same way a cord work in scorpion/catapult.<br>you can do a test to prove it even without a workshop and in no time.<br><br>pencil or a stick,<br>a piece of para cord (any non elastic cord),<br>rubber band,<br>a chair,<br><br>Use the chair legs to attach the p.cord/, place your pencil in the middle of the loop you get and start rotating-twisting till it goes. The results will speak for themselves I guess.<br><br>I'm talking out of my intuition so I might not be right lol <img src="" alt="Very Happy" longdesc="1">
