FIG. 3: FIRING MECHANISM
Install the prong, trigger and trigger ring accurately to ensure smcxjth operation of the trebuchet. Here's how:
1. Install the prong on the trigger as shown in the section drawing. Lash the prong to the trigger with twine.
2. Lower the long end of the beam. Position the trigger on the edge of the short crossmember, so that it stands vertically, touching the beam. Drill a pilot hole and screw the trigger to the short crossmember. Don't tighten the screw too much—the trigger must pivot easily.
3. Lower the beam again until the sling-attachment hole is level with the trough's bed. Position the trigger ring (a 7/l(>-in.-dia. screw eye) underneath the beam, so that the prong will hook the trigger ring and keep the beam cocked. Install the screw eye and lash it to the beam with twine.
