Build A Catapult In Your Backyard

Wilson provides photos of the building process, detailed and updated plans, plus construction information on ballistas, onagers and trebuchets. You will aso find information on catapult web sites and how to be included in some of the catapult contests around the country. Also included is some interesting catapult history, its strength and weakness as a weapon, and what it was that led to its demise as a functional war machine. There's no question that warriors have found more efficient means of lobbing projectiles at enemies, real and imagined, but has it ever been as much fun?

This text is a compilation of step-by-step instructions for how to build nine different types of catapults and trebuchets. Each set of instructions includes dimensional drawings of all wooden parts, lists of required hardware and sources, an abundance of photos, diagrams, and detailed descriptions of the assembly process.

Are you a bushcraft fanatic, planning to travel into the wild anytime soon? Or are you looking for a simplified guide to know virtually all there is to survive in the woods? If so, then read on… Bushcraft involves the use of specialized skills and knowledge to survive in an outdoor situation, especially in the wild. Without adequate bushcraft knowledge and survival know-how, your journey into the woods would be less than fun, i.e., you become exposed to severe and life-threatening situations that you may not survive from. Thus, you must equip yourself with the requisite skills and knowledge to thrive in the wild, such as developing a tough survivalist mindset, foraging for food and searching for water, building a shelter, making a fire, signaling for help, and a whole lot of other survival life-hacks. And this is why this book, Bushcraft Survival Guide, was written to help you uncover all you need to know about bushcraft and its survival mechanism for thriving in the wild, irrespective of the nature of the circumstances you encounter. Below is a snippet of what you will learn in this guide: • Meaning: You will get to understand what bushcraft actually entails and why it should not be confused with camping. • Practicing bushcraft and survival mindset: You will discover how to find the best places to practice bushcraft, including how to build a tough survival mindset if you want to make it out of the woods alive. • Bushcraft tools and equipment: You will be educated on the essential tools and equipment needed to survive in the woods, which cuts across shelter and sleeping kit, carrying kit, cooking and water, personal hygiene, and clothing. • Surviving in the bush: Everything you need to know to thrive in the woods is discussed here. For example, you will learn how to build several types of shelters for warmth, navigating in the bush using a compass, sun, and other methods, finding, cooking, and preserving food, as well as how to make a fire, among others. • Wilderness survival mistakes: The common wilderness survival mistakes to avoid before you journey into the bush are discussed in this section. And a whole lot more! Do all these sound interesting to you? Yes? Then stop overthinking this and listen to that part of you urging you to get a hold of this guide instead of the apprehensions of the what-ifs and should-I's holding you back.

A man’s home is his castle, or so the saying goes, but could it withstand an attack by Attila and the Huns, Ragnar and the Vikings, Alexander and the Greeks, Genghis Khan and the Mongols, or Tamerlane and the Tartars? Backyard Ballistics author William Gurstelle poses this fascinating question to modern-day garage warriors and shows them how to build an arsenal of ancient artillery and fortifications aimed at withstanding these invading hordes. Each chapter introduces a new bad actor in the history of warfare, details his conquests, and features weapons and fortifications to defend against him and his minions. Clear step-by-step instructions, diagrams, and photographs show how to build a dozen projects, including “Da Vinci’s Catapult,” “Carpini’s Crossbow,” a “Crusader-Proof Moat,” “Alexander’s Tortoise,” and the “Cheval-de-frise.” With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind many of the projects, and shows where to buy the materials. By the time they’ve reached the last page, at-home defenders everywhere will have succeeded in creating a fully fortified home.
