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 . n the lower edge and allowed torest on the lower frame. This gives a good starting point forlaying out the holes on this sheet. The boiler will be lowered machinery and the parts to be cleared. The illustration istaken from a common construction in use on the average sizelocomotive. The plate is about J/^ inch thick. The kneesare machined at B for the plate C. They are machined to fitthe frame. Usually a card accompanies a drawing, showingthe size of this sheet. The radius R of the sheet is made fromYs, to yi inch larger than the radius of the boiler, so as toadmit of ease in fitting up. This sheet is planed along thelower line D. where it rests on the knees, and in line centralwith the boiler. Scribe off any projection that there may be of the sheetbeyond the knees. The bolt holes for securing the sheet tothe knees are now scribed off from the knee. While thesheet is being held in position by several clamps, get the wasteangle-iron G, and try it to the boiler. This will rarely fit up.
