Tube base notcher

Abstract

A base (10) and the method for fabricating the corners (32) of the base (10) of a piece of furniture (12) from tubing (18) by notching the tube (18). The notching removes a metal from the tube (18) along the first pair of extremities (40) converging to an apex (44), and along a second pair of transverse extremities (52). Additional material is removed from the spaces (38) by removing a plug from the tube (18) adjacent the apex (44) in the shape of a bowl having two parallel sides (56), a third side (58) perpendicular thereto and a point (44). The tube (18) is folded at each point (44) creating corners (32) in the tube (18) each with a space (38) and an enlarged relief space (46) therebetween to allow fluids used in the post-fabrication operations, i.e., washing and painting, to flow quickly therefrom thus increasing drying times. The gussets (62) are welded to the tube (18) to add strength to the base (10).
