Machines sorted by type and size:
Catapult Style |
Description |
Small |
Medium |
Large |
Traditional Trebuchet |
Traditional trebuchets are historocal catapults powered by a counterweight, usually
with a heavy weight on one side of the arm, and a sling and projectile
hanging off the other.
|
|
|
|
Traction Trebuchet |
Traction trebuchets are historocal catapults powered by humans
pulling on ropes, effectively acting as the counterweight as with
traditional trebuchets. Traction trebuchets are the easiest to
create and operate, as you don't have lots of weight to bring with
you. You do, however, need to train the counterweight crew.

|
|
Ballista |
Ballsitas are torsion engines originally designed around 400BC.
They are powered by two bundles of twisted rope, arranged in
the form of a big crossbow.
|
|
|
|
Hatra Ballista |
Hatra Ballista is a torsion engine with two bundles. Unlike the
greek ballista, a Hatra ballista is configured so the bowstring
and arms rotate toward the center, providing a much better
configuration for throwing heavy objects.
|
|
|
|
Onager |
Onagers are torsion engines, designed with a single bundle, and
an arm and sling.
|
|
|
|
Air Cannons |
Air Cannons use a resevior of compressed air behind a valve.
When the valve is opened, it will push the projectile down the
barrel. Pnuematic cannons are similar to other kinds of cannons,
but without the use of explosives.

Engines Of War:
Team Tormentum has built over 20 different machines of all sorts,

competitions, and others for fun.

You won't find any detailed plans for any of our machines, but you will learn
a few tricks and that make our machines work.

Team Tormentum drags catapults of all sorts to various public events. Everything
from local High Schools to the World Championship Punkin' Chunk'. We've been
battling for over 25 years and documented over 30 events.
