This kit is an intermediate difficulty. There are lots of parts to glue and some need to be lined up by hand. It takes me about 30 minutes to go from a pile of parts to a fully working trebuchet.
Here it is firing some little wooden "bullets".
Step 1: Gather Materials
- One set of wooden parts. Use attached PDF.
- One cloth sling. Use attached Basket.pdf for a pattern.
- Some ballast for the counter weight. (nuts, small bolts, BB's, lead shot, etc)
- Wood glue
- strong thread or thin string
- A long twist tie, some masking tape, small wood clamps or other way of securing some of the parts while the glue dries.
- Some 400 grit sandpaper (optional)
Feel free to make as many kits for personal use as you want. (It's not alright to sell kits without my permission, OK?) The basket on the counterweight is a "living hinge" design. It bends where the laser scored it. There are 2 on the template since it's the most likely part to break during assembly. It's probably not possible to do on a scroll saw. You will need to modify the design somewhat.
