Fig. 107 the bend is not allowed to touch the corner of the anvil;struck as indicated by the arrow; turned, end for end,and struck again; placed on the face of the anvil as(a) in Fig. 108; and struck on the ends. These blowsare to be repeated, with occasionally a blow to bring the piece nearer to aright angle, until a sharpcorner is made on theoutside and the piece isnearly at a right corner can now befinished by standing thepiece on end and strik-ing as indicated by thearrow in Fig. 110 andfinally closing in to theexact right angle. In all this work the corner must bekept at a good heat; the angle must be more than 90°at all times with a small fillet on the inside. Never letit get into the position shown at (d) () or the metal will lap over and pro-duce a crack as at (a), or a cold shut as at(e). The piece should be finished all overwith a flatter. A bend with a squarecorner as shown at (a) (Fig. 107) can be forged withoutbeing fullered and drawn clown. All other op
