You want to make one? Ok look at this picture of trebuchet https://i.pinimg.com/originals/52/16/4a/52164a7fbba0294f7e8f06769744a045.jpg
You see the arm with the sling attached? Thats the only part you need to make for handheld version. My original one was broom handle arm. Notice one of the sling cords is fixed to the arm. The other sling cord has to slip off as you launch it to release the projectile. I put a smooth headless nail into the end of the broom handle for that purpose. Make a loop in the end of the sling cord, put it over the nail. You can bend the nail until the sling cord slips off at the right moment to get the best trajectory.
