This simple homemade work is useful in cases where you need to measure the angle and transfer it to the part or workpiece. In the people, such a device is also called a "memory" of angles. To make a template you will need one old square, which you have not used for a long time.
Of course, such a tool can be bought at a hardware store, but a home-made square pattern will cost less. Yes, and time for the manufacture of this device will require very little. If there is no square at hand, you can use a steel flexible ruler.
How to make a jig from a square
To make a template, you first need to disassemble the square - we are interested in a plate with a marking. We draw a longitudinal line in the center of the plate and cut it in half using angle grinders. As an option, you can also cut the plate with scissors for metal, but the grinder will be faster.
With the help of angle grinders we remove the burrs and round one edge at each workpiece. Then we make a through hole. If desired, the plates can be shortened a little. Two halves can be fastened together using a bolt with a nut or put on a rivet. What specific fasteners to use - decide for yourself.
Working with such a tool is very simple and convenient. We apply a home-made template to the corner that you need to "remember", and then transfer it to a wooden or metal blank. How to make a conductor from an old square, see the video on our website.
