Grid beam is a modular, reusable building system that is fast, easy, affordable and virtually goof-proof. Ordinary people, with few skills and even fewer tools (all you need is a wrench!) can tackle projects ranging from furniture and shop benches to more ambitious projects such as wind turbines, truck racks, small buildings -- even electric vehicles. Grid beam's modular pieces and bolt-together construction make the system fast and straightforward to work with. It has all the advantages of an industrial building system: standard, modular sizes; uniform materials; and interchangeable parts. Projects knock flat and are easy to transport. Since the pieces can be used over and over again, grid beam is easy both on your wallet and on the environment -- the authors have been using some of their components for over 30 years. This book includes hundreds of photographs of real projects built over a 60-year period, showing the many uses of grid beam, from shelves for college students to projects involving alternative energy. The versatility of grid beam is inspiring for beginners, more experienced do-it-yourselfers, and innovators who will develop their own designs. Even school-age children can use grid beam to build simple projects.
