trebuchet II
the second quick iteration on a simple trebuchet design
With many lessons learned , and only a little pre-planning, I've launched into a second trebuchet build. I'm looking at a 10' arm on an 8' tall frame. Around 18 pieces will be bolted together to constitute the machine. Custom-poured concrete blocks serve as counterweight.
here's an early launch with about 120+ lbs of counterweight and a half liter bottle projectile; more of the same on my vimeo page.
I posted my SketchUp files at the bottom; some things may look odd because I stopped drawing once I could figure out the basic dimensions. I will most likely develop an instructable for the project once this thing has fired satisfactorally.
a running to-do list for myself:
- find the plywood with my other to-do list..
- need more cotter pins
- lengthen sling
- paint
- sand down pin disc
