Eric Gunnerson has recently blog about a Trebuchet (that he offered to his wife?). This remembered me of the one I built, with my friends, a few years ago.

The photo below shows the "implementation" of the Trebuchet and some facts about it:

  • the rotating pole was 7m long and composed of two wooden poles of 15cm of diameter
  • the rotation axis was made of a steel stick of 26mm of diameter. It was at 3.5 m of the ground. Note because the construction was not perfectly symmetric, it got twisted.
  • the "counter"-weight was about 100kg altough not measured,
  • the structure was composed of 10 wooden poles buried 50cm into ground.
  • the projectile was a piece of wood, 50cm long, 15cm diameter, it got throwed at around 60 meter althought the trajectory was far from behing optimal (too vertical).

Did you get bored and go chop down a bunch of trees just to build that?
