Okay, you want to build your Trebuchet first. This site will be tips and tricks of the trade. Okay, let's get to business.
The first question we must ask is whether you want to build a "historically correct" Traction Trebuchet, is simpler and easier to design and nephew, the building counterweight Trebuchet.
If you create a Trebuchet with the sole purpose of your high school physics teacher is entertainment, then you might consider one of thecounterweight diversity. If on the other hand, is a Trebuchet for fun or self-construction of education, traction Trebuchet is something to take seriously. (Remember that at least three quarters of plans for "free" on the Internet is counter-weight flavor.)
Once the draft plan contains, you will probably need to decide on an appropriate size. If you're trying to launch bowling balls the length of a football field, you will get a much bigger when you Trebuchetplans for the eggs with the incoming traffic. What, of course, is a bad thing to do. (Based on personal experience, most managers have swath dried eggs from their windshield it.) Another point of interest or Trebuchet September premade or design plans for the sale Trebuchet. If you are a beginner kits are excellent for use. The plans will also help you if you are simply amazing, a rookie.
Now the next step is building your Trebuchet. For most people, ISet with 1 "x2" pine for all the pieces. But if you want to build a Trebuchet top 10 feet, a shelf for 2×4's. When Trebuchet-wise structure is completed, there will be a slingshot to build a counterweight adapted to be used. I prefer to cut any old rag and put lengths on both sides' of rope.
Counterweights fit can vary from one window / bottle filled with lead shot, a sock full of rocks or a weight Halter. When allthat things are in order, you must attach the trigger mechanism and release the stylus. There are plans and photos of them in most places, but the only advice I can give is that the release pin the most difficult part of building a Trebuchet is. Should be tilted so that the sling releases the projectile at an angle of about 45 degrees from somewhere.
Last Words: Building a Trebuchet can be very funny and a great learning experience. (Or sometimes a bit unbelievable for these unfortunatephysics students like me). Build your own kind to quality care and support, where necessary, adding that last long, you know.
