Greek and Roman Ballista


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

The Greek and Roman Ballista is the granddaddy of all field artillery. This display quality model is fully functional and really works!



The Ballista was an engine of war invented by the Greeks in 800 BCE, and later adopted by the early Romans. Ballistas were constructed of different sizes for the various purposes of siege and field warfare. The largest ones could throw projectiles weighing up to fifty pounds as far as 400 yards!

The ballista uses a pair of skeins (bundles of twisted rope) for power. Similar to the working of a crossbow, the Ballista actually preceded the crossbow in western culture by over a thousand years and is where we get the word "Ballistic".

This model shoots five-inch long, 1/2" diameter bolts (also called darts) about thirty to forty feet (when property constructed). It stands ten inches tall, twenty inches long and the arms sweep an arc over twenty inches wide. When not shooting bolts, this model is a great addition to your bookshelf or desktop.

More than thirty five parts are included in this kit, but it can be easily assembled in one day. Everything you need is included except for glue and a few simple tools like scissors, sandpaper, a file (a utility knife would be helpful too) and about three to six hours of your time from start to finish.

Features include:

  • High quality, naturally white hardwood.
    Can be stained any color.
  • Precision cut by computer.
    All parts guaranteed to fit properly!
  • Authentic trigger and winch mechanism
  • True skein torsion power- not a wimpy spring
  • Actual range from 20 to 40 feet or more!

The instructions are highly detailed and complete with full-color photos, diagrams and historical notes. This kit can be assembled to a finished model in three to five hours, plus glue-drying time. Some light sanding may be necessary 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!



* Warning: This is a representative model of a real ancient military weapon. Use only with competent adult supervision.
* Shown stained as red oak. The kit ships as a natural, unfinished poplar wood product. Colors may vary.
* Can throw 40 feet when properly constructed and using appropriate missiles. Your performance may vary.



Tools required:
Scissors, Glue, Ruler, and a utility knife. Sandpaper is optional.

Notes:
Why should a kid
build a catapult?

Because the world needs good engineers and scientists, and because the kids who will grow up to become engineers and scientists need a way to get hands-on experience with physics, math and engineering.

In this age of 200-plus channels of TV, the Internet and computer games, kids are also spending far less time building tree houses, tinkering with engines, or designing downhill racers. We believe those are important skills to have. They help form the basis for good problem solving skills and an innate understanding of the real, physical world that you just can't get from a computer game, no matter how good its physics simulation software is.

Ballistic motion was one of the key players in the development of the science of physics. The word "engineer" even originated as the builders and designer of Siege Engines

Why is a budding engineering student expected to take a year or two of calculus in high school, but she isn't expected to have any real-world experience in building or working with machines and materials? Pencil and paper (or computer screens) are only one part of the learning experience. Where will she apply all of the stuff she learned in geometry and trig? Without physical projects to touch, feel and see, the lessons become abstract, their utility questionable.

A catapult project gives students a chance to see that science and engineering really can be fun, and it's a lot more than just numbers on paper. The real payoff for an engineer is in the field, where she can see and enjoy the results of her ingenuity. And it may seem counterintuitive, but engineering projects not only help kids learn math and science, they are also great at getting kids back outdoors, away from the massive over-exposure to video games, TV and the Internet.

Why all this interest in getting kids to study science and engineering? Because it's important to our society, and it's great mental cross training regardless of what field of work the kids eventually go into. Most people develop a sense for what they want to do in life while they are still in high school or even earlier. A catapult project is fun and interesting enough to inspire some kids to study the science behind how they work, and then go on to become the engineers and scientists of tomorrow.
