Wood Router
The router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. It routs (hollows out) an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. They may be handheld or affixed to router tables. Some woodworkers consider the router one of the most versatile power tools. There is also a traditional hand tool known as a router plane, a form of hand plane with a broad base and a narrow blade projecting well beyond the base plate. CNC wood routers add the advantages of computer numerical control (CNC). The laminate trimmer is a smaller, lighter version of the router. Although it is designed for trimming laminates, it can also be used for smaller general routing work. Rotary tools can also be used similarly to routers with the right bits and accessories (such as plastic router bases). History Before power routers existed, ...

Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

George Keller (architect)
George Keller (December 15, 1842 – July 7, 1935) was an American architect and engineer. He enjoyed a diverse and successful career, and was sought for his designs of bridges, houses, monuments, and various commercial and public buildings. Keller's most famous projects, however, are the Soldiers and Sailors Memorial Arch in Hartford, Connecticut, and the James A. Garfield Memorial in Cleveland, Ohio. Biography He was born on December 15, 1842 in Cork in Ireland to Thomas Keller (1804–1880) and Susan Pratt (1805–1888). Keller emigrated with his family to New York City as a child. Irish immigrants were at the time considered inferior, and during his early years Keller endured a considerable measure of hardship and discrimination. Lacking connections and unable to obtain schooling in Europe like many of his professional peers, an ambitious nature and a school of hard knocks education gave Keller an adequate base of knowledge. As a young man, he accepted employment with an I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
