Fixing the plates

To connect two perpendicular boards with screws, they must be set exactly at right angles. Only after that you can drill the pilot holes for the twist screws. Smaller and medium-sized boards can be fixed in a straight line for drilling and screwing, a wooden instrument made of scrap pieces of wood. In this device, the vertically and perpendicular plates are fixed by several wooden wedges and thrust blocks screwed to the base of a piece of plate..
