Riving Knife
A riving knife is a safety device installed on a table saw, circular saw, or radial arm saw used for woodworking. Attached to the saw's arbor, it is fixed relative to the blade and moves with it as blade depth is adjusted. A ''splitter'' is a similar device attached to a trunion on the far side of the saw and fixed in relation to the saw table, which must be removed to make any non-through cuts or dados within the depth of the wood. Function A table saw is typically used for cross-cutting and ripping; cross-cutting slices a board across its grain width-wise, ripping cuts lengthwise along the grain. Various conditions experienced while cutting either way can cause a partially cut board to move, twist, or have the saw blade's kerf close up and bind the blade. Poor blade or fence alignment, operator error, or pre-existing stresses in the wood released by cutting may cause these different and dangerous conditions. A riving knife rides within the kerf, pivoting on the saw's a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hand Saw
In woodworking and carpentry, hand saws, also known as "panel saws", are used to cut pieces of wood into different shapes. This is usually done in order to Woodworking joints, join the pieces together and carve a wooden object. They operate by having a series of sharp points, called teeth, of a substance that is harder than the wood being cut. Hand saws have been used for thousands of years. Egyptian hieroglyphs, Egyptian hieroglyphics exist depicting ancient woodworkers sawing boards into pieces, and ancient bow saws have been found in Japan. Cut patterns on ancient boards are occasionally observed to bear the unique cutting marks left by saw blades, particularly if the wood was not 'smoothed up' by some method. Twenty-four saws from eighteenth-century England are currently preserved.Olmert, Michael (1996). ''Milton's Teeth and Ovid's Umbrella: Curiouser & Curiouser Adventures in History'', p.178.

Health & Safety Executive
The Health and Safety Executive (HSE) is a British public body responsible for the encouragement, regulation and enforcement of workplace health, safety and welfare. It has additionally adopted a research role into occupational risks in Great Britain. It is a non-departmental public body with its headquarters in Bootle, England. In Northern Ireland, these duties lie with the Health and Safety Executive for Northern Ireland. The HSE was created by the Health and Safety at Work etc. Act 1974, and has since absorbed earlier regulatory bodies such as the Factory Inspectorate and the Railway Inspectorate though the Railway Inspectorate was transferred to the Office of Rail and Road in April 2006. The HSE is sponsored by the Department for Work and Pensions. As part of its work, HSE investigates industrial accidents, small and large, including major incidents such as the explosion and fire at Buncefield in 2005.

Stop Block
A stop block is a simple reusable jig used in metalworking and woodworking to locate a common edge of a workpiece so that multiple workpieces can get the same operation performed quickly. Common applications are table saws and manual milling machines, but they are also used on miter saws, band saw A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumb ...s, radial arm saws, and abrasive saws. Stop blocks used in metalworking usually have a small rod that slides parallel to the vise jaws and can be tightened in a particular position. Stop blocks in woodworking are typically nothing more than wood blocks clamped to a rip fence or auxiliary fence so that a distance from the saw blade can be maintained between cuts.

Featherboard
A featherboard is a safety device used when working with stationary routers or power saws such as table saws or bandsaws. The purpose of a featherboard is to apply pressure against a workpiece, keeping it flat against a machine table or fence A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or net (textile), netting. A fence differs from a wall in not having a solid foundation along its .... Featherboard shapes and sizes vary depending on the tasks for which they are intended. A serviceable featherboard can be shop-fabricated from an approximately 3/4 × 3 × 11 inch piece of straight grained, defect-free wood cut crosswise at a 45-degree angle on one end. Several parallel cuts in the direction of the grain create fingers or "feathers" that flex in the direction of workpiece travel, preventing the workpiece from being dragged backwards by blade friction. Featherboards are also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bandsaw
A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw.. The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches (teeth per inch, or TPI), which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic. Band saw is recommended for use in cutting metal as it produces much less toxic fumes and particulate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Table Saw
A table saw (also known as a sawbench or bench saw in England) is a woodworking tool, consisting of a circular saw blade, mounted on an mandrel, arbor, that is driven by an electric motor (directly, by belt, by cable, or by gears). The drive mechanism is mounted below a table that provides support for the material, usually wood, being cut, with the blade protruding up through the table into the material. In most modern table saws, the table is fixed and the blade position can be adjusted. Moving the blade up or down affects the depth of the cut by controlling how much of the blade is protruding above the table surface. Many saws also have an adjustable angle, where the blade can be tilted relative to the table. Some earlier saws instead had a fixed blade and the table could be adjusted for height (exposure of blade) and angle relative to the blade. Types The general types of table saws are compact, benchtop, jobsite, contractor, hybrid, cabinet, and sliding table saws. Bench ...
