5 pieces are cut from the 4'x8' plywood to make a table 2'-8"x 6'-8" . The top is cut from the middle surounded by 4 leg rail combination pieces oriented on the plywood so that the grain is consistent on all these L shaped pieces. These frame pieces slot together ; the top is held on by an Alpha Hardware male & single female end connection at each corner. With these connectors permenantly attached the table can be assembled & dismantled without special tools. A rubber malet be useful.
