It has been used by all the major builders on all continents. Including the Greeks, Romans, ancient Chinese, Mayans and Incas. It is a versatile instrument that makes it easy to find a square, any part of a circle or an angle. The framing square may have been the tool that inspired Pythagoras. Secret carpenter’s squaring numbers you can prove on your framing square – 3-4-5, 5-12-13, 8-15-17, 7-24-25. The modern framing square is one of the most versatile tools in a craftsman toolbox. This tool is used to layout everything from foundations to framing right through to fine cabinetry and clocks. The square will help you layout almost any material. With it you can calculate and maintain a constant angle. Calculate materials, do area & square layout, find slopes, layout polygons and circles. You can calculate stairs, roofs, windows, doors, trim and cabinetry. Layout any angle. Basic unit squaring is made quicker, easier and more accurate with the brace scales. Quick rough estimates are easy using the square and a tape measure. Using the scales and measurements you can convert inches to both decimals and fractions of a foot. A variety of circle math skills are possible with this tool Framing square course – imperial measurements In this course you will learn how to use the various traditional & modern scales and measurements found on a square. 1)Basic roof and stair layout with the square will be introduced.
