Fig. 2 is an end elevation of one-halfof the piece to be laid out. Divide the quadrants AB and CD,Fig. 2, into any number of equal parts—in this case eight. Draw dotted lines from points l to 2,2 to 3, 3 to 4, etc. Connect the points2 and 2, 3 and 3, 4 and 4, by solidlines. Draw the triangles shown at Figs. 3 and4, making the perpendiculars, or the 2 3, Fig. S, equal 2 3, Fig. 2, and 23, Fig. 5, equal f2, Fig. 4, and draw thedotted line 2 3, Fig. 5. Make 2 3, Fig. 5, equal to 2 3, Fig. 2,and draw the solid line 3 3, Fig. 5. Proceed in the same manner with thebalance of the plate. A line drawnthrough the points i to 9 and i to 9will complete the outline of one-half ofthe plate; lap and flange to be added.
