<p/><br></br><p><b> About the Book </b></p></br></br>From the author of "Backyard Ballistics" comes this updated edition of his history of catapults with instructions and diagrams for building 10 authentic working models. Illustrations.<p/><br></br><p><b> Book Synopsis </b></p></br></br>Calling all pumpkin chuckers, wannabe marauders, and tinkerers of all ages! Flinging things and playing at defending your own castle has never been more fun. <br> Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey--ancient artillery devices known commonly as catapults. <br> Updated and improved instructions and diagrams illustrate how to build 10 authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. <br> The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier Jon Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle. For the legions of Tolkien fans, budding backyard warriors, and engineering wizards, this book is a must-have. <br><p/><br></br><p><b> About the Author </b></p></br></br><b>William Gurstelle</b> is a professional engineer who has been building model catapults and ballistic devices for more than 30 years.
