Starting at one end of the metalstrip, mark the length of each side by spacing with thedividers, making a light impression on the metal at eachpoint. Lines drawn through these points across the strip,as shown in A, 1234561, will mark the corners where 186. s *<* ST3 p p p o p o QdiOj 1 «3 •** /* |\ &• ^ \ ^ / N u % Oi <^ J * 188 SHEET METAL WORKERS MANUAL the metal is bent when formed into shape; Vs-inch isadded for a lap seam, as shown at x.
