Belt sander

Belt sanders were one of the first power tools used in the growing field of power tool drag racing wherein a pair of stock or modified belt sanders are placed in parallel wooden channels and fitted with long extension cords. Each heat begins when a common switch or individual switches triggered by the racers energizes them, causing the sanders to race towards the end of the track spitting wood dust along the way. Stock sanders race down a track, while modified sanders race on a track. Sanders of all shapes and sizes can go very fast or very slow, depending on the power of the motor. For example, some can go as fast as 8 km/h (5 mph) etc. ==Wide belt sander==

A wide belt sander is used to machine stock flat and to specific thicknesses. It consists of sanding heads, contact drums and a conveyor belt. The sander is electric powered but relies on air pressure to control the abrasive belt. A rubber conveyor carries the stock through the machine while a wide abrasive belt removes material from the top surface. It is sometimes used in conjunction with the jointer to create square and true stock. This type of sander has applications in woodworking and furniture production. It does fine sanding using rigid sanding pads and air cushion pads, cross and diagonal sanding as well as lacquer sanding. ==References==
