Trebuchet Plan

The Free Trebuchet Plan - this plan shows the layout and design of the Little Dragon Trebuchett. It is an easy to make Trebuchet with one moving part and is powered by a simple counterweight and has a base that is twelve inches (12") in length. The swinging arm is sixteen inches (16") This is a pretty easy project to make and you can do it in a couple of hours. It is quite poweful and of course the power is dependent on a few factors that you should experiment with like the length of the swing arm and how heavy the counterweight is.

One big factor in the efficiency of the trebuchet is the location of the pivot point on the swing arm. The free plans for this project recommend you drill several holes so you can experiment with this factor. I recommend you screw and glue all the parts together for maximum strength. Of course everything is just recommended and you should feel free to modify anything you like and substitute anything for the parts you have available.

The Free Trebuchet Plan is located at the bottom of this page:

If you came to this webpage directly from a link or a search engine: This Trebuchet plan is the plan that accompanies the tutorial on how to make a trebuchet. The tutorial takes you through all the steps, complete with lots of pictures, on how to make the Little Dragon Trebuchet. . You can find the assembly tutorial here: The Lttle Dragon Trebuchet (There is also a video of the Little Dragon firing off)

I have also put a larger version of this trebuchet plan on a clean webpage so you can easily print it out. Here

About the Trebuchet Plan

There are a couple of things I want to point out about the plan:

• The Red Marks are screws or nails and glue. This shows how the different parts of the trebuchet are affixed to each other
• Dotted Lines - if you are not familiar with blueprints the dotted lines represent parts that are behind other parts.
• The plan points out the location of the pivot point. This is four inches (4") from the counterweight side of the swing arm. This is a location that worked well for my trebuchet but you may want to tinker with this. How heavy your counterweight is has an effect on this.
• The Pivot Point: is the axle from a toy car

The Miniature Trebuchet - The trebuchet was the ultimate artillery weapon of the medieval period and early renaissance. A large and unwieldy weapon, it was typically built on-site during battle, and tuned to lob great weights - such as the carcasses of rotting horses and pots of burning pitch, over the castle walls and onto its inhabitants. This is our newest and smallest trebuchet design in a long line of catapult kits. Designed by master trebuchet expert Ron Toms, this machine is ideal for the student on a budget or as a wonderful display piece for any desktop or bookshelf of any history enthusiast. Precision carved by computer controlled machinery for guaranteed fit and accurate joinery. The detailed instructions include loads of photos of each step of the construction process, tuning tips and safety notes. Included in the kit are four wooden projectiles, all the necessary components for the sling, trigger, and counterweight bucket as well as all the parts for the kit. The only thing you'll need to supply are 64 pennies for counterweight and a few simple tools - Scissors, a ruler, a utility knife, wood glue and a few rubber bands to hold the pieces together while the glue dries. Tools required: Scissors, Glue, Ruler, rubber bands and a utility knife. Sandpaper is optional. Additional Counterweight Required: 64 pennies. Range: About 10 feet.
