What is a framing square?
Frame square, also known as a steel square or carpenter square, is a common tool used by the carpenters, general suppliers, masonry suppliers and do-it-yourselfers. In fact, the L -shaped is instead of a square, the frame square is usually made of aluminum or other metal. It has a long arm that forms a right angle with a shorter arm. Longer arm is usually used to measure right angles and also provides its surface tables and scale commonly used carpenters in a wide range of projects. Anyone involved in a construction project or a project that requires prepared access to tables and scales will find in many aspects of calculation of angles, cuts and playgrounds. The narrower arm, called the tongue, is usually 1.5 inches wide (3.81 cm). Wider arms are referred to as a blade and is usually 2 inch (5.08 cm) wide. In addition to using the accuracy of right angles, it is also used for proper layout and space rafters, stairs and hip rafters.
Standard frame square usually measures 24 inches (60.96 cm) long and 16 inches (40.64 cm) long. However, there are variations and longer and shorter tools are available. Although it is assumed that this instrument has been for centuries, the first reference to its size was in the 19th century, when it was described as 18 inches (45.73 cm) by 12 inches (30.48 cm).
square framing usually has three scales: diagonal, foot on the plate and octagonal. More modern framing squares also have graphs of conversion for different playgrounds and their fractional counterparts. Usually there is also a table of numbers called the table of rafters on the face of squares. This allows the carpenter to quickly calculate the neckline and building factors based on the Pythagorean sentence.
long used by European craftsmen and builders, framing squares received a patent in the United States in 1819. The man who patented was the southern Shaftsbury, Vermont, the blacksmith named Silas Hawes. It is said that the fraudster paid him for his horse's shoes byHe put several old blades that joined together to create the first carpentry square in the ground. In 1820 he founded Eagle Square Manufacturing Company with a collaborator Stephen Whipple.
