Concealed Hinge Jig
A concealed hinge drilling jig is a type of support jig, designed for drilling 3 cm holes to fit concealed hinges into modern wardrobe doors. As many of the complementary tools used in woodworking, it uses an electric hand-drill for its operation, making a Forstner bit to turn. For most ''concealed hinge''s to work properly, a pit hole must be created on the door at the point where it faces the static part of the hinge which is screwed to the inside wall of the wardrobe. To create the pit hole, the jig must be fixed in place by means of the provided clamp, spin the Forstner bit by applying an electric hand-drill to its axle. The hole is drilled by pressing the hand-drill until a satisfactory pit hole is created. The purpose of the grinding (abrasive cutting), drilling jig is to hold a Forstner bit in place, at a 90º angle while drilling 3 cm pit hole. The angle of the tool is critical for the performance of concealed hinges, the jig allows maintaining the 90º angle ov ...

Drilling
Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross section (geometry), cross-section in solid materials. The drill bit is usually a rotary Cutting tool (machining), cutting tool, often multi-point. The bit is Pressure, pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off Swarf, chips (swarf) from the hole as it is drilled. In Rock (geology), rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside the hole (top-hammer drill) or within the hole (down-the-hole drill, DTH). Drills used for horizontal drilling are called drifter drills. In rare cases, specially-shaped bits are used to cut holes of non-circular cro ...

Grinding (abrasive Cutting)
Grinding is a type of abrasive machining process which uses a grinding wheel as cutting tool. A wide variety of machines are used for grinding, best classified as portable or stationary: * Portable power tools such as angle grinders, die grinders and cut-off saws * Stationary power tools such as bench grinders and cut-off saws * Stationary hydro- or hand-powered sharpening stones Milling practice is a large and diverse area of manufacturing and toolmaking. It can produce very fine finishes and very accurate dimensions; yet in mass production contexts, it can also rough out large volumes of metal quite rapidly. It is usually better suited to the machining of very hard materials than is "regular" machining (that is, cutting larger chips with cutting tools such as tool bits or milling cutters), and until recent decades it was the only practical way to machine such materials as hardened steels. Compared to "regular" machining, it is usually better suited to taking very ...

Drill Tip Forstner
A drill is a tool used for making round holes or driving fasteners. It is fitted with a drill bit for making holes, or a screwdriver bit for securing fasteners. Historically, they were powered by hand, and later mains power, but cordless battery-powered drills are proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, and utility projects. Specially designed versions are made for surgery, dentistry, miniatures, and other applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earlies ...

Benjamin Forstner
Benjamin Forstner (March 25, 1834 – February 27, 1897), was an American gunsmith, inventor, and dry goods merchant best known for his Forstner bit, a drill bit which enables the creation of accurate flat-bottomed holes in wood, regardless of grain orientation. Early life Forstner was born in Beaver County, Pennsylvania. Forstner bit In 1886, Forstner patented the Forstner bit. The bit was revolutionary as it did not feature the lead screw (which Forstner called the "gimlet-point") or and thus proved especially useful to gunsmiths and high-end woodworkers. The bit was unsurpassed in drilling a smooth-sided hole with a flat bottom. It was also better than Russell Jennings twist bits for boring at an angle and not following the grain of the wood. Forstner eventually made arrangements for the manufacturing and sale of his bit with two Connecticut firms: Colt's Manufacturing Company of Hartford, and Bridgeport Gun Implement Company, successors to Union Metallic Cartridge C ...

Woodworking Tools
Woodworking is the skill of making items from wood, and includes cabinetry, furniture making, wood carving, joinery, carpentry, and woodturning. History Along with stone, clay and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials. Among the earlliest finds of woodworking are shaped sticks displaying notches from Kalambo Falls in southen Africa, dating to around 476,000 years ago. The Clacton spearhead from Clacton-on-Sea, England, dating to around 400,000 years ago,Allington-Jones, L., (2015) ''Archaeological Journal'', 172 (2) 273–296 The Clacton Spear – The Last One Hundred Years the Schöningen spears, from Schöningen (Germany) dating around 300,000 years ago and the Lehringen spear from northern Ge ...

Door Furniture
Door furniture (British English, British and Australian English) or door hardware (North American English) refers to any of the items that are attached to a door or a Drawer (furniture), drawer to enhance its functionality or appearance. Design of door furniture is an issue to disability, disabled persons who might have difficulty opening or using some kinds of door, and to specialists in interior design as well as those usability professionals which often take their didactic examples from door furniture design and use. Items of door furniture fall into several categories, described below. Hinges A hinge is a component that attaches one edge of a door to the frame, while allowing the other edge to swing from it. It usually consists of a pair of plates, each with a set of open cylindrical rings (the knuckles) attached to them. The knuckles of the two plates are offset from each other and mesh together. A hinge pin is then placed through the two sets of knuckles and usually fix ...
