Step 9Firing and Adjusting the Trebuchet
I decided to make a video for this step because otherwise it would be too confusing to describe.

Adjusting the Trebuchet
For more power, add more weight to the counterweight. Here are some ideas for filling your counterweight:
- Bricks work well, but only if they fit width-wise
- thick gravel will work sometimes, but sand will seep through the corrugation
I ,however, used a 20 pound shirt of maille armor that I made last year. It fits perfectly and does not shift during the firing sequence.

suggestions put some wood in crucial areas for stronger,(longer lasting) device , you could use old wall paneling for uter most layers or all the layers(you can cut with razor utility knife and do everything EXACTLY as you did here. it would be much stronger.
I think your push pull on the release arm was sheer elegance (simple), and if you do wood make it threaded rod into a nut set in the wood/cardoard arm then you can simply make it longer shorter by turning it.
thanks this was truely magnificent. My kid may want to build one, me too !!!
