Where we saw wood splitting, we handmade braces out of metal to release some of the stress. Then the delving began, after much research, we finally found. We compared the abilities and mechanics of trebuchets to catapults at first, and we were convinced trebuchets were the way to go. From the beginning we had wanted to build a trebuchet, so that was the primary objective here. We used a rectangle pin because it only has two points of contact. It was a very intense time, since we had so little of it. ![]() The pin's angle is an essential piece to your trebuchet. Mount the last Eye Hook on the arm between the two you added to the frame. Mount 2 Eye Hooks to the center of the frame where the arm falls. Today, this birdseed thief learned a valuable lesson.or maybe I just had some fun. With the chute, we diverted from the original blueprints due to time constraints and were happy with the end result as it allowed our arm to have more clearance on the wights we added, which in turn gave us more flexibility on our trebuhcet. but then made a few modifications to make it better. We also found adding grommets to the holes where our rope was tied to the sling, since the force tends to tear through it rather easily. We also recommend using 550 paracord since it has the best fitting characteristics to our project. We highly recommend this structural support.įor the sling we used a canvas bag material. Launch 3 - New squirrel launcher design. If you enjoy watching and feeding the wildlife in your backyard, you’ll find loads of great free plans to build feeders for squirrels. We added support trusses where the support beams meet the 50'' bars to add even more support. 97K views 2 years ago squirrel catapult squirrellaunch. After that we used both SolidWorks and a Virtual Trebuchet Simulator to test. With the brace's height's only limitation was our mitre saw's angle of 50º, we put brackets in the corners and we had a trebuchet frame.įor our design we used SolidWorks to build it virtually. The frame was built around that, we gave the length 2 6' 2x4's and the width 2 28" 2x4's. Valid 9.00 CDN Available as a PDF Download before you pay. With a pivot height of 48" to the dot, we then put together an 8' arm with the pivot point placed in the spot we felt was the best after some math. Squirrel Catapult Structure Plan for Launching the minor creatures into your neighbour’s backyard. Then we took into account the limitations the rules gave us and pushed everything to the limit. I wanted to build one that is ultra lightweight, easy to transport, has a safety feature along with a more compact power supply that is easily chargeable. (It will be given references, before we turn it in.) Then the delving began, after much research, we finally found the information we needed to have the perfect trebuchet. ![]() It was a very intense time, since we had so little of it. When we were first assigned this project we had to go through so many options and learn about so many new mechanics.
