The Stirling Warwolf Trebuchet


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


This highly detailed kit includes a working, historically accurate winch, trigger, trolley-block system, authentic half-lap and mortise and tenon joinery and more!



During a siege of Stirling Castle in 1304, Edward Longshanks (Edward the first, King of England) ordered his engineers to make a giant trebuchet for the English army, named "Warwolf".

With one blow, Warwolf leveled a section of wall, successfully concluding the siege of Stirling Castle. The Stirling Warwolf is generally thought of as the most powerful and most famous of the trebuchets in history.

With an authentic and historically accurate "squirrel-cage" winch mechanism, block-trolley system and working trigger, frame-ladder (for re-cocking), half-lap and mortise and tenon joinery, this is the most highly detailed and historically accurate trebuchet kit you can get. This kit has well over 140 pieces in it, plus two true scale-sized medieval warrior figures. At 1/20th scale, this machine stands 18 inches tall at the apex. The arm reaches to a height of 32 inches, and hurls its projectiles 40 to 60 feet! At 1/20 scale, thats about 800 to 1200 feet for a life-sized model. Even the projectiles (included) are scaled properly to represent 100 lb. and 350 lb. missiles.

Highly detailed and computer cut for accuracy, this model is a joy to build. The detailed instructions are complete with diagrams, photos, tuning tips and even historical notes about trebuchets.

Tools you will need include glue, a flat file and a 1/4" round or rat-tail file, clamps or rubber bands, household scissors and sandpaper to smooth any rough edges (there shouldn't be many.) The only other things you'll need to supply are a few hours of time, a little effort and some pennies for the counterweight bucket.

The kit is made from high-quality white hardwood. It can easily be stained any color, but simple exposure to sunlight will turn the natural wood a rich golden-brown over time.

We've put a lot of time and effort into making this kit as easy and complete as possible. We hope you'll enjoy building and shooting it as much as we have!


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

Assembly time:
For a Master carpenter doing a sloppy job: about 6 hours.
A person with no kit building experience being extremely meticulous: about ten days.
The model in these photos was built by Ron Toms over two days time.

Assembled Size:
- Height: 18" at the main axle, 32" to the tip of the arm.
- Length: 22"
- Width: 18"

Additional Counterweight Required: 720 pennies recommended,
(Or loose nuts and bolts, other coins, rocks, anything that
can fit into the 2" x 2" x 5" counterweight box.)

Range:
- 40 to 60 feet with the included wooden ball projectiles.
(Optimal range assumes a well tuned machine)

Shipping weight: 10 lbs.
Box dimensions: 36" x 12" x 4"

WARNING! This is a functional model intended for display and/or educational demonstrations of physics. It contains a fast moving arm and projectile that can cause injury if you make contact when firing. Use only under strict, competent adult supervision.

* You'll need to supply the counterweight material. 720 pennies are recommended, but anything from nuts and bolts, BBs, coins, sand or a good fist full of pebbles will do!

* Can throw 60 feet when properly constructed and tuned with sufficient counterweights. Your performance may vary.

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.
