Sometimes we are so passionate about our work or hobby that we get engulfed by it and every other living thing in our lives suffers the consequence of that. As the dust of the season settles, we have to get through loads of work either to catch up on targets or to prepare for the next quarter of activity and the challenges that come with it. Once in a while though it’s therapeutic to take a step back and chill a bit, change our perspectives and put on the bird’s eye view.
In the case of this woodworker and craft enthusiast, making a craft that was to be a fun yet safe, way, for his kids to play with, was definitely the best use of his time. The Cord Powered Catapult turned out really well and appeared not to be a play thing for kids only but for adults too…
Here are the plans for a small desktop catapult ideal for ping pong ball or marshmallow fights. The spring force is provided by a twisted string mechanism, so it lasts and lasts, in contrast to rubber band-powered catapults. The cool thing is my kids can safely battle each other (so long as the missiles are limited to marshmallows).
This design includes a variable stop, allowing you to adjust the trajectory of your missile by arresting rotation of the throwing arm at 3 different angles. See the video on this page.
To complete this you’ll need a length of 1×6″ wood, some strong cord, and a dowel rod (?1/4″?). The plans can be printed from the freeware drawing program Inkscape, or viewed in 3-d form in the freeware Sketchup.
Tool-wise, you’ll need a drill (press would be ideal, but hand drill would do) and a detailing saw of some sort (band saw and scroll saw would be ideal, but a jig saw would do). You’ll also want a can of spray adhesive to stick the plans to your wood.
The moving parts are all held together by the string. Thread it around one crank, through the vertical arms, around the throwing arm, through the other vertical arm, around the other crank, and back, several times. Tie it off firmly then you are done.
You can follow the link below for all the plans and diagrams you’ll need to build. For now here’s a 30 second on how to cock the catapult for firing:
Most probably not the first diy catapult wooden catapult you’re seeing but you’d agree with the superiority of the string function and professional touch of the entire setup. You should make one for yourself or for some kids. That’s a whole lot of Pokemon crashing fun for all!
