With over 300 step-by-step pictures, the Backyard Bowyer is geared for the beginning bowyer, backyard hobbyist, and anyone who has ever pondered building a wooden bow. Easy to read and follow steps go down to even the smallest detail in the design and construction of basic archery bows. Learn to craft fine wooden bows without huge investment in equipment and materials, and without being bound by location and limited workspace. Learn to construct: A classic target flat bow, an English Longbow suitable for hunting, and even your own strings and arrows for traditional and primitive archery.

Archery is almost as old as mankind itself, manifesting in almost every culture and on almost every continent. It is in many ways our link to the past and the stepping stone into another age. It is one of the few ancient pastimes that are still relevant today. Yet nowadays, getting into the ancient sport of archery can be daunting for the average person with no experience or previous exposure to the subject. For many, the hefty price tags on modern bows or the seemingly impossible task of building a bow can be a surefire deterrent. Many do not want to pay the price of a decent bow to try their hand at the bow and arrow, simply to see if they enjoy it or not. If only there was a way to make a bow good enough for a beginner without expending or gambling an immense amount of time or money on it. What if you were told that there was such a bow? That hidden in the ground, in the heart of buildings, on the shelves of most hardware stores, and perhaps even in your home, there was a material that made it all possible? Would you believe it? Well it is true, and that material is PVC pipe, the white or gray plastic pipe that can be found virtually everywhere. It is possible with only a minimal investment and an hour of labor to make a fine bow for target archery that performs just as well as bows worth more than ten times as much. A bow that, if given a little more time and effort, can be made into an efficient hunting tool or serious target shooter. The Impossible Bow shows you how to construct your own PVC pipe bow, with bows ranging from the incredibly simple to the incredibly complex. Learn to build simple bows that require a minimum of tools and little time, more complex bows that can be modified to fit the target archer as well as the experienced hunter looking for more of a challenge, and finally a bow that accurately replicates the weapons of war of the steppe nomads. The best part is that even the most complex bow should cost no more than 10 dollars and be completed in a day, yet can hold up to the rigors of daily use. Don't let anything hold you back from enjoying one of man's oldest and most noble of sports. Join the backyard archery revolution with your very own bow that will defy everything you know and will baffle anyone who sees it. Join me in building an impossible bow. Author's Notes: The bows in this book are great for kids of all ages, from the young to the young at heart. Because of the ability of these bows to mimic many historical bow designs, this book is great for re-enactment archery as well as for the target archer. If made well, one design in particular works well for hunting, and can be modified to work just as well as many primitive hunting bows. This book covers how to make the generic PVC pipe bow that has been the mainstay of do-it-yourself archery for some time now, as well as a couple designs which bring out the hidden performance of PVC as a bow material. These bows also work well for survival situations and can be made small and can be kept virtually anywhere out of the sun. In the trunk of a car, in a boat, in a hunting cabin, your basement, your attic, the list goes on and on. This book goes over how to make smooth shooting bows from 30 to 70 pounds of pull that can perform well if taken care of. While they aren't top performing bows, they can certainly be used for hunting, fishing, and target archery.

Whether it's out fishing, in the woods, at the range or even in the backyard, the sport of archery in all its forms can be fun and rewarding for all ages. In this day of mass production, the draw of being able to make something with your hands is greater than ever. PVC plumbing pipe, with its unique blend of qualities, offers both the experienced and beginner archer an opportunity to build their own dependable bows without any previous experience. Simple PVC Pipe Bows shows you how build a solidly performing bow with little in the way of equipment, work space, time and material cost, whether it's one or hundreds. Youth Recurve : A small and light bow at home in the backyard as well as on the range. It'sperfect for women and teen archers with its shorter draw and compact size. While geared for young archers, this bow can hold its own as a short pack bow or training bow for an archer of any age. Horse Bow : This reflexed bow reminiscent of the short bow of the nomads of Central Asia and Eastern Europe is ideal for learning the art of mounted archery. With a smooth draw and compact size, this bow is a sweet shooter on foot as well. Snakey Recurve : Designed after wooden bows which work with the natural contours of gnarled wood, the snakey recurve is an ideal bow for the hunter or fisherman looking to craft his own equipment. Its serpentine curve brings the string in line with the center and tilts the handle making for a bow that is more accurate and comfortable to shoot.

Archery is a great sport and many understand the benefits of taking a bow while camping, hiking or traveling. Yet if you need to travel by bus, foot, plane or bike, it can be very difficult to carry a full-sized bow and set of arrows with you. PVC plumbing pipe, while an unlikely bow material, allows for compact and effective take down bows to be made. With just a few simple techniques, a simple pipe can be transformed into a powerful and compact traditional bow that can easily fit in a pack or bag. Take-Down Archery will show you how to build your own bows, put together take down arrows, make strings and other essential tools for your own portable archery kit. Take-Down Bows : Form PVC pipe into effective archery bows that break down to a compact size. These bows can be made to fit easily in a bag or pack, making them great for camping, hiking, travel or just transport without worrying about a large bow. Take-Down Arrows : Convert commercial arrows into break-down versions that fit right alongside a take-down bow. Also build a jig for putting feathers and vanes on your own arrows at home or in the field. Bow Strings : Build the jigs and tools to help make your own durable and efficient bow strings. Learn to make an endless loop bow string, a basic but efficient and precise string for any traditional bow. Release Aid : Make a simple release aid that saves your fingers and increases accuracy with shorter bows. Arrow Rest : Shoot both feathers and plastic vanes with a simple flip style arrow rest.

The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

I can't really explain my attraction to the bow and arrow. I can't explain the pull of a camp fire either, or the ocean, or the open hills where you can see forever. It's just there. These things are in all of us I think, some vestige of our primitive past buried so deep in our genome as to be inseparable from what it is to be human. What we think of as civilization is a new experiment in the eyes of Father Time. Experts say that humans have been around for some fifty thousand years. We've been carrying the bow for maybe five thousand (atlatls and spears before that), and pushing the plow for maybe two thousand. We have been hunters forever. We are built to run, to pursue big game on the open savannas, to kill and eat them. With the dwindling of the Pleistocene mega fauna, mammoths and such, the bow became more important and indeed helped to make us who we are today. It still holds that attraction, same as the hearth. When I was a kid I would make crude bows from green plum branches, big at one end and small at the other. A discarded hay string would serve as a bowstring. My arrows were fat and unfletched and would scarcely fly more than a few yards, usually tumbling over in midair. The small creatures around our home were plenty safe. When I was about 12 or so my brother brought me two old Ben Person recurves he'd found at a yard sale. One was a short bow, probably no more than 48 inches and the other was more of a standard size. They both drew about 50 lbs if I recall. That fall happened to be a good year for cottontails around our little farm and I spent countless hours walking the fields and shooting at them as they busted from underfoot. Although I'd get several shots a day I never did hit one on the fly but I remember that fall fondly nonetheless. The pleasure of jumping rabbits and seeing the feathered shaft streaking toward them was a thrill I've never forgotten. I made my first "real" bow when I was in high school, after getting a copy of the Traditional Bowyers Bible in the mail (more on this in a moment). My first bow, a decrowned mulberry flatbow, broke within about 10 shots. The second held together quite well and is probably still around somewhere and capable of shooting an arrow, though it would probably draw about 70lbs. When I first started making bows I used the woods I had close at hand; mulberry, common persimmon, red maple, white cedar, etc. I'd probably made more than a dozen bows of various woods before I ever saw a piece of Osage. People often ask me where they can find a bow stave and, invariably, I tell them to use what they have close by. No matter where you live, you'll have something near that will make a bow. Go cut it down and get started. This book is an attempt to share some of what I've learned over my years of bow making. The Traditional Bowyers Bible series, as mentioned earlier, is still a great source of information. Why write another book on making wood bows you might ask? The simple answer is that there are so many ways of doing and explaining things. There are still unanswered questions and we'll cover many of them here. We will cover all of the most frequently asked questions, and lay out a simple plan that should guide you through the entire process, from finding a stave to stringing your bow and shooting your first arrow. Some of what you'll find here, you'll find nowhere else.

Desktop or DIY 3D printers are devices you can either buy preassembled as a kit, or build from a collection of parts to design and print physical objects including replacement household parts, custom toys, and even art, science, or engineering projects. Maybe you have one, or maybe you're thinking about buying or building one. Practical 3D Printers takes you beyond how to build a 3D printer, to calibrating, customizing, and creating amazing models, including 3D printed text, a warship model, a robot platform, windup toys, and arcade-inspired alien invaders. You'll learn about the different types of personal 3D printers and how they work; from the MakerBot to the RepRap printers like the Huxley and Mendel, as well as the whiteAnt CNC featured in the Apress book Printing in Plastic. You'll discover how easy it is to find and design 3D models using web-based 3D modeling, and even how to create a 3D model from a 2D image. After learning the basics, this book will walk you through building multi-part models with a steampunk warship project, working with meshes to build your own action heroes, and creating an autonomous robot chassis. Finally, you'll find even more bonus projects to build, including wind-up walkers, faceted vases for the home, and a handful of useful upgrades to modify and improve your 3D printer.
