Catapults

Science Project Experiment Catapult Kit (S.P.E.C.K.)

The Ultimate Science Project Experimenter's Catapult Kit! It's fully adjustable, multi-configurable and repeatable. It's a perfect model for learning the scientific method! All in all, there are more than 400 different configurations and tuning options possible with this kit. Suitable for hundreds of experiments and learning opportunities. The completed frame is 14.5 inches long, 7 inches wide and 11 inches tall. The arm measures 20.25 inches long with multiple axle and power attachment points. This machine can hurl projectiles up to 40 feet, depending on configuration, tuning, and lots of other variables! What you can learn: This kit provides a real world, hands on example of many aspects of basic physics. It exposes the student to concepts of mechanical advantage, levers, gravity and energy, to name a few. It can demonstrate the storage and conversion of potential energy to kinetic energy through levers, and it is equipped with optional wheels, to demonstrate conservation of momentum. All in all, the concepts of efficiency, power and work can be demonstrated and applied. This kit is useful for teaching engineering, science, design of experiments, problem solving and cause-effect relationships. It was designed to get students to think about physics in a real world, tangible context. Theories can be made and tested; this process, and analyzing why the observed results occur can ultimately lead to other, more advanced concepts in physics, mechanics and mathematics. Analyzing the data can make use of statistical methods from basic averages to much more advanced topics if desired. With 18 pages of instructions including assembly of every basic configuration, suggested experiments, tuning guidelines, independent and dependent variables to record and measure, data tables, historical information about trebuchets and catapults, and more, it should be easy to get started with this Ultimate Science Project Kit!

Catapult Kit

Lay Siege To The Doghouse! Right after you build your own working medieval catapult. All you'll need is glue, scissors and a steady hand to construct this wooden, Canadian-made siege engine kit. The finished catapult stands 6" tall x 5" wide x 10" long and will toss assorted stuff (meatballs?) 15 feet or further, depending upon the stuff. Comes with detailed instructions. Note: Please don't propel small mammals, and please don't put anyone's eye out.

Catapult Activity Kit

Pathfinders Catapult Kit

The catapult has been around in many forms, evolving since about 400 BC. This model is based on the medieval styles that were used during the middle ages. Just add glue, scissors and an appreciation for the physics and art behind this medieval siege engine

Trebuchets

TK-3 Model Trebuchet Kit

Designed and made in the USA for better quality, better performance! The new TK3 model trebuchet can demonstrate all the principles of the trebuchet as either a hanging counterweight machine, or quickly convert it to a wheeled fixed counterweight machine (and back again!) Which is better? Which one is more efficient? More accurate? More fun? Now you can be the judge! This professionally engineered model requires only two or three hours and a little glue to assemble. The only tools you'll need are a pair of scissors and (optionally) a utility knife. It has a 15 inch throwing arm, is 18 inches from front to back, 9 inches wide and 13 inches tall at the axle. This is a working model capable of tossing the included wooden missiles over 40 feet! The detailed instructions are complete with diagrams, photos, tuning tips, and even efficiency equations for calculating your maximum theoretical range! All parts are pre-cut, pre-drilled and can be assembled to a finished model in one evening (plus glue drying time). The trebuchet is a fantastic demonstration in physics and dynamics. One of the big debates in recent years among historians is whether trebuchets in history used wheels to increase their efficiency and make them more portable, or if they were built on-site without wheels and with counterweights hanging from the end of the arm. This debate was even explored in a recent TV documentary (NOVA, Secrets of Lost Empires: Medieval Siege). 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 science and history! * The counterweight box is supplied, but you'll need to supply the counterweight material to fill the box. For best performance, we recommend using 360 pennies for counterweight and/or two 1-1/4 lb. barbel weights (barbel mounting inserts also included).

Desktop Trebuchet

Defend your desktop! The mere presence of this striking machine on your desk will induce fear and respect among your peers. Take charge and besiege your opponents with a fully functional, genuine trebuchet for your desk! It really works! It takes about two to four hours to assemble, which is a joy in itself with the hand selected wood and computer-controlled, precision cut parts. The professionally designed kit and fully detailed instructions - 10 pages of descriptions and tips, with of photos of every step - makes assembly a breeze. All you really need is some glue and a pair of scissors. For a more refined look, a little sandpaper and a small, round file would be helpful, but are entirely optional. Performance! This mighty desktop artillery is capable of hurling the wooden ball projectiles (included) over twenty feet! Just load-up the counterweight bucket with about 150 pennies and you've got a fully-loaded machine. Use less counterweight for shorter range, or experiment with different configurations of sling length and projectile/counterweight combinations. The desktop trebuchet is a fantastic way to demonstrate the pinnacle of pre-gunpowder mechanical engineering technology. Great for classrooms or school science projects, or just a great display piece on your bookshelf or desk.

Stirling Warwolf Trebuchet

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 all 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, that equates to 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 operating it as much as we have!

Floating Arm Trebuchet

Engineered using modern mechanical principles and computer aided design, this mini-powerhouse can hurl a golf ball over 200 feet. It uses guillotine action and a plunging beam to maximize potential energy and a floating arm to convert that energy into projectile motion. Precision crafted of high quality hardwood, the kit contains everything you need to build a working model.* The trebuchet is essentially a gravity powered energy conversion machine - it's a great way to see classical mechanics in action! The completed model stands 34 inches tall, 18 inches long and 7 inches wide (12 inches wide with the included steel counterweight boxes). A common complaint from engineering professors is that "Students today have a great understanding of computers, but fewer and fewer of them have any real hands-on, real-world understanding of physics and mechanics." Our kits are designed and intended to spark an interest in real-world science and engineering, and maybe even a bit of history too! The detailed instructions are complete with diagrams, photos, tuning tips, equations for calculating the machine's efficiency and more! All parts are pre-cut, pre-drilled and can be assembled to a finished model in one evening (plus glue drying time). 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 physics and engineering! WARNING! This is a functional model intended for 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. * We supply the containers, but you'll need to supply the counterweight material. Anything from nuts and bolts, BBs, coins, sand or a good fist full of pebbles will do! * Can throw 200 feet when properly constructed and tuned with sufficient counterweights. Your performance may vary.

Siege Towers

Siege Tower Kit

Pathfinders' innovative wooden science kits build working replicas of the most infamous and powerful, medieval siege engines, the Siege Tower, the Catapult and the Trebuchet. Weapons that once smashed castle and fortress walls changing the course of many a kingdom! Building the kits allow children and adults to explore the link between design, materials and technology. A wonderful lesson in how basic mechanical principles turned simple materials into very useful and effective tools. Pathfinders' kits are designed by Derek Wulff, a science educator in British Columbia, and made in Canada. The kits are based on historic designs. The kits use only wood and rope. Pieces are joined by wooden dowels, not screws or nails. No elastic, rubber, motor or batteries are used to create the movement of this device. All pieces are pre-cut and drilled requiring only wood or white glue to assemble. The instructions are detailed and complete with educational notes about the siege engine. When completed, the mighty Siege Tower Kit features a working 5" catpult on top, a drawbridge and ladders. It is 15" tall, 6" wide and 7" deep. This kit is suitable for children 10 and older taking an hour or two to complete. Safety instructions are included and children are recommended to use under adult supervision. While these scale models will only be smashing down imaginary castle walls, they are loads of fun to build and use.

Onagers

X-treme Onager

Siege the day! This modern design for an Onager uses the exact same principles as the ancient Roman war machines. It is capable of hurling small stones, golf balls, walnuts, eggs, tennis balls and even small potatoes from 20 feet to more than 50 feet! It all depends on how much power you build into it and the weight of your projectiles. Precision crafted of high quality hard wood, the kit contains everything you need to build a working model in one evening. The ONAGER (also called a Mangonel) uses a bundle of twisted ropes (called a skein) for real torsion power. This type of torsion engine is so powerful, a full-sized machine could hurl a bowling ball almost 1/4 of a mile! The finished scale model stands 17" long, 14" high and 12" wide. The kit is precision crafted from high quality hardwood and includes a working winch and real leather sling-pouch. The detailed instructions are complete with diagrams, photos and tuning tips so you can get the most out of this fun project. All parts are pre-cut, pre-drilled and can be assembled to a finished model in one evening. 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! * Golf ball and tennis ball missiles are not included. * Can throw over 50 feet when properly constructed and tuned. Your performance may vary.

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! 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. Please note: photos show product stained a red-oak color. This item ships as plain whitewood.

Ballista

Ballista Wood Kit

Made from high quality knot free Basswood, this Ballista is a great addition to any homemade artillery collection. Inspired by Alexander the Great's Artillery of the Macedonian Soldiers, this ballistic firing machine is a working model easily assembled from pre-cut and pre-drilled pieces. Includes laser cut plywood wheels. -- Size: 11-1/2" long, 9" wide, and 5-1/2" tall

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. 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 six hours, plus glue-drying time. Some light sanding may be necessary to smooth any rough edges. * 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.
