Laying out for boiler makers and sheet metal workers; a practical treatise on the layout of boilers, stacks, tanks, pipes, elbows, and miscellaneous sheet metal work . tance of one-quarter of the length of the sheet, or from the riglit quarter line and draw the bottom quar-ter line at right angles to C-C. Also lay off this distance fromthe bottom quarter line and draw the left quarter line. If theconstruction has been accurately made the distance from thetop quarter line to the right-hand edge of the sheet should inches. This distance, together with the 20 inches atthe left-hand edge of the sheet, should equal one-quarter thelength of the sheet. Check these distances over to see that quarter center lines. Divide the distance between both quarterlines and right quarter line into twenty-five equal spaces. Layoff twenty-five equal spaces in each one of the other twoquarters. Lay off nine equal spaces from the right-hand lineto the left-hand edge, and lay off sixteen equal spaces betweenthe top quarter line and the right-hand edge of the sheet. Therivets in the first and second row will come opposite eachother all around the sheet.
