Art of the Catapult
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. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. Instructions and diagrams illustrate how to build seven 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. 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 John Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle.

Ice Free
Everything you always wanted to know about the technology of EVs in one volume: motors, batteries, controllers, heating, air conditioning, 12 volt systems, plus some topics that aren't discussed widely even in specialised books; such as the management of long strings of individual cells. For the faint-hearted there are also refreshingly simple explanations of the electro-magnetic and mechanical principles needed to understand how motors and batteries work. One chapter is devoted to alternative technologies such as compressed air drive, hybrids and flywheel energy storage. A final chapter makes the economic and social case for EVs and gleefully demolishes a number of myths about the problems of electric drive. The book is profusely illustrated with over 200 photos, line drawings and other illustrations
Pleating
This concise book, with more than 300 photos of pleated high-fashion creations and practical diagrams to follow, offers the basics needed to understand and use fabric pleating successfully. A foreword by Jack Sauma, founder of Mood Designer Fabrics, reminds us of how essential pleating is to the design world. Throughout, step by step explanations show you how, by understanding the types of pleats and their requirements in terms of fabrics, grain, bias, and other factors, you can improve your designs' creation process, budget planning, and "wow" factor. Authors Leon and George Kalajian are the father-and-son team heading New York's preeminent Tom's Sons International Pleating. While their firm caters to couture evening wear and runway fashion, the concepts and definitions they clearly explain in this book will allow everyone to properly execute and communicate designs to others in the industry. This is an essential reference for designers, seamstresses, pattern makers, costumers, factory owners, students, and everyone involved in fashion.
