What is a double square?
It is mainly used when adjusting the machining and wood processing after the measured pattern must be maintained, the double square is a tool of measurement used to measure square angles in multiples of two. This is made possible by a part of the tool that allows you to move one of the two main parts of the double square: a sliding blade. Double squares attract engineers who specialize in exact parts, as well as woodworkers for use in small measurement projects. Any person who specializes in patterns are undoubtedly used by a double square.
The two main components of the double square are referred to as a rule and blade. The rule is generally a tempered ruler, made of durable metal and most often 12 inches (30.48 cm) long with a groove or rail running along its length. The ridge, rail or groove depends on the preference of the manufacturer, but in any case it must be perfectly parallel to the long edges of the rule. It is also a responsibility for action as a guide whenever the blade must bemodified or moved along the length of the ruler for correct measurement.
The blade is a moving part on a double square and is most often produced with a mechanism to secure the blade against the rule. This security device is usually a hook or notch that usually matches the placement of a groove or rail on a rule. The rule leads the blade in a direct way against each other, and when the correct measurement is achieved on the rule, the blade is secured in place, usually a screw or clamping device. The blade is generally made of tempered steel, which, although heavy, also offers stability and durability - necessary aspects of a precise tool.
Double squares can be made of different materials: aluminum, steel, titanium or various alloys that can be used to produce a square that lasts and ease of abuse, which may occur in the store environment. Some are relatively simple mechanisms while JIné boasts several accessories, depending on the application in which the double square is generally used. The levels of the bubbles are popular accessories to the double square blade, as well as magnetic strips that help to secure a double square to certain materials that work with.
