Desktop Onager, in Red Oak

Cut from solid Red Oak!


Designed and made in the USA for
better quality, better performance!


This version of the kit is cut from high quality Red Oak instead of the whitewood (Poplar) used in the
other version of this item.

This awesome little machine is the perfect desktop item to enforce the peace in your cubicle or dorm
room. It really works!

This all wood and twine machine has no metal parts! Find out how the ancients were able to use nothing
but wood and ropes to build machines that could hurl heavy stones great distances. These machines were
the predecessors of cannons and modern artillery!

Measuring nine inches long, six inches tall and using the mighty torsion skein for power, this beast hurls
wooden balls (included) up to twenty feet across the room. Food fight? Load it up with olives,
marshmallows, maraschino cherries... the choices are endless!

Simple and easy to build. This kit includes everything you need except for glue and a few simple tools like
scissors, sandpaper, a file (a utility knife would be helpful too) and about two or three hours of your time
from start to finish. It's a far better use of your time than watching TV, and you'll have a really
cool desk ornament when you're done. And don't forget, it not only looks cool- but unlike those other
little desktop catapults we've collected, this one really works! (It works well too.)

Features include:

  • Precision cut from high quality solid red oak
  • Authentic leather padded strike bar
  • True skein torsion power- not a wimpy spring
  • Range from 10 to 20 feet or more!

What you get:
The kit includes seventeen wooden parts, one hardware bag containing twine, trigger, wooden pegs and
ammo, and assembly instructions.

The instructions are highly detailed and complete with full-color photos and historical notes. This kit can
be assembled to a finished model in two to three hours, plus glue-drying time. Some light sanding may
be required to smooth any rough edges.

We've put a lot of time and effort into making this kit as easy and complete as possible. It's a fun way to
learn about history and engineering!

Catapult

A catapult is any kind of device that shoots or launches a projectile by mechanical means. In England, a catapult is what we call a slingshot in the US. A catapult is also the part of an aircraft carrier that launches airplanes off the deck.

But for our purposes, a catapult is any of the ancient types of artillery, including Onagers, Scorpions, Trebuchets, Ballistae, Springalds, Coullards, Bricoles Perriers and more.

But most people tend to think of a catapult as the one-armed torsion machine used by the Romans. This is also known as the Onager or Mangonel.

Mangonel

The word Mangonel derives from the ancient Greek word "Manganon", literally meaning "engine of war". The Romans called it a Manganum. In pre-medieval French the word Manganum was changed to Manganeau, and the English changed that to Mangonel in the 1300s.

The history gets a little sketchy in the middle ages, but some historians believe that "mangonel" was shortened to the word "gonnel" about the same time that cannons were being developed, and later still, "gonnel" was shortened to "gun." And still today, in the military a "gun" is strictly a piece of big artillery.

Onager

Onager is originally the name for the wild Asian donkey. This donkey bucks like a bronco if anyone gets too close to it, and it is known to kick stones at people and predators too. So when the Romans needed a name for their one-armed torsion catapult, they called it the Onager!

The Onager (catapult) has a single arm that is powered by a large skein of twisted ropes. The ropes were usually made from hair or sinew for their elastic properties.

Trebuchet

The word "Trebuchet" is originally French, and meant something like "to fall over or rotate about the middle" as in a see-saw rotating on its axle. It also seems to have meant a big, heavy beam. Today a Trebuchet is any kind of catapult that is powered by a massive counterweight on one end of an arm, and a sling on the other end. This includes Perriers, or "traction" trebuchets which are powered by a mass of people pulling one end of the arm with ropes.

Ballista

This is a two-armed torsion device invented by the Greeks. It works similar to a crossbow, but instead of a flexible bow, it uses two stiff arms powered by twisted rope skeins like an Onager. The ballista predates the Onager by several centuries and was used to hurl stones (lithobolos style ballista) and also bolts or darts.

Obviously, this is where we get the word "ballistic".
