Here we are presenting a woodworking plan that will allow you to make a simple and useful Try square hand tool.

Try squares made of wood are very practical pieces of shop equipment, and are quick and easy to make. They can be made to any size up to a metre in length.  Use the dimension given here only as a guide. When making this tool it is most important that the straight edge and the stock are glued up perfectly square, otherwise all the work done with it will be inaccurate.
