Many wooden structures have fork or socket-tenon connections. Both forklifts, as well as the pivots themselves, require a very precise marking and, of course, cutting them out. In the case of a larger number of pivots or routing points, it is worth making a simple template made of sheet metal with a thickness 1 mm. We put it on the forehead of a wooden patch or square timber and use a pencil or a stylus to draw lines that define the identical shape in all elements. If we use aluminum sheet, the template can be easily cut out.
