I have to make a catapult for my Principals of Engineering class, and we have to pick our own materials and construction methods.
I was thinking of something kindy heavy, like Cedar, but if might be to hard to work with.
What about Balsa? It's light and stiff, but I don't know how strong it is, and I'm afraid it might crack at the pivot points.
Where should I use glue? Does would glue work just fine or should I get that Gorrilla stuff?
Rosewood? That stuff is expensive, but it's strong. So is Cherry.
Plywood? Or is that too pedestrian? I am a Weight Weenie/OCP'er you know.
The catapult has to be powered by a spring, and is about three feet tall.
