METHOD FOR THE CREATION OF CLEARANCE HOLES
According to this invention, slots are made on the plane of any material; the depth of these slots is equal to half the thickness of the plane, plus the length of the radius of the stay bolt or stud to be entered, plus a tolerance margin; the slots have the required length and are made on two or more sides of the plane, in an alternate manner, so that the slot made on one side overlaps by a few millimeters the slot made on the opposite side, creating in such a way the space for the passage of a stay bolt and stud that serves as the anchorage for the various pieces that make up to object to be realized.
