Onager Jr was our first torsion siege-engine of the medium scale that functioned well.

Onager Jr was constructed after building my Baby Onager model, and it looks very similar. It recycles hardware from Balista Jr. The main reason for it's construction is that of portable party machine. This onager fits nicely on the roof of my car, and can fling a pile of potatoes 150 feet.

After a successful chunk at the Zukapult 2005 contest. This final iteration of Onager Jr on a lift-frame which allows for the longer sling.

After installing some wheels and new rope. This form of the machine in 2002.

Flinging some rocks in Maine.
