About Try Squares
A try square is a woodworking used to measure and mark pieces of wood, or metal when used in metal working. It is so named because to "try" a surface means to check its straightness or correspondence to an adjoining surface and "square" refers to the accurate right angle measuring capability.
The try square serves as a marking and measuring devices when pushed against a piece of wood. Pre-marked increments on the try square blade simplify making precision measurements.
Try squares are also used to test right angles. To do this, the stock butts against either the face side or joint edge of the work surface. If light is visible between the try square and the wood, the surface is not level and square.
