Day 26
The Sportsman supervised a science school project I am doing with my Gr 8 daughter.
She has to build a Middle Age siege weapon, and do a video and write-up. She chose to build a trebuchet, one of those sling catapults that was used to break down castle walls.
Naturally this means I am researching, designing and building a trebuchet, while my girl passes the tools and does the odd jobs...
The video and write-up is on her!
Figuring out how to make a counterweight
It is surprisingly tricky to get right, you have to tune the arm length, the counterweight mass, the sling length and the sling release trigger just right to get a good projectile trajectory.
The final product. This one works surprisingly well after a bit of fiddling. No the Sportsman did not go flying.
A big old girl in action...
