Locate the point G, which is 4 inchesabove the line A B and 2 inches fromB L M. With G as centre and 2 inchesradius, strike the quadrant M N D tan-gent to B L M. Directly above the pointG locate D, which is on the quadrantM N D. Connect by a straight line the points D and C, thus completing the out-line of the cowl. Now divide the backinto four equal parts as shown byA J F K C. Similarly divide the throat.
