THE OZNOG'S HOMEMADE BALLISTA

The Spruce Moose is an Amtgard-designed ballista which is technically accurate (except in power) to Greek and Roman designs, yet can be built for about $75 all from standard hardware store parts. Unlike many nonperiod designs, it derives its power from the torsion spring- a winding of rope twisted very tightly that springs back violently. It is very easy to load, aim, and fire. If the finishing touches are put on the reloading mechanism, it will genuinely require three people to operate, but will fire very rapidly. Power can be adjusted to suit local standards.
