How to Build a Trebuchet (Parts list for the Build)

The Recommended Tools for this project

Most of these tools are just recommended and you can vary the tools depending on what types of materials you use for this project. Here are some tips: Needle nose pliers are best for manipulating small parts but if you don't have any then any other type of pliers will be fine. The metal file shown in the center of the picture is recommended any time you work with metal - you should always file down cut metal so there are no sharp edges. The sandpaper shown is attached to a block; this makes sanding small parts easy and you should always sand every piece of wood you cut so there are no splinters.


  • Hammer
  • Saw
  • Screwdriver
  • Pliers (needlenose)
  • Wood Glue
  • File
  • Scissors
  • Drill and Bits
  • Sandpaper
  • Cutters for metal

Miscellanous items needed to Make the Trebuchet

About the miscellaneous materials: The counterweight is very important and you should find something as heavy as possible. I used a chinese healing ball for my trebuchet but you can use items found around the house like batteries taped together, penny rolls taped together, a lump of heavy clay or even a rock.

  • Heavy object (three different ones are shown on the far left) only 1 needed
  • Small screws
  • Small Nails
  • 2 eyehooks
  • wire or bread ties
  • Electrical tape (or masking)
  • 3 feet of string
  • piece of cloth - 6 inches.
  • Paints (optional)
  • 1 sheet of cardpaper -similar to cereal box (shown under the paints)

Wood Needed for the Project

About the wood: The wood I used is about one inch by one half inch thick. You can be very flexible with this and use almost anything similar. You can cut strips of wood if you need to. The sheet of wood shown is important for strength and it is about one quarter inch thick but thinner would be ok.

  • 1 16 inch piece
  • 2 12 inch pieces
  • 2 10 inch pieces
  • 3 5 inch pieces
  • 1 square piece of flat wood about 5-6 inches

Okay! This is everything you need to make this table top Medieval Siege Weapon. Let's start with the building instructions.
