Bench Work Slzeef meh! Slwp When we first enter the sheet metal department, we ore introduced to the tools and the machines we will use in our worlg. Some of the tools we become familiar with are- the riveting hammer, the rivet set, and the airplane snip. Of machines we learn the use of these: the burring, the thick edge, the crimping, and the sheet iron folder. ln sheet metal work we must acquire proficiency in measuring, cutting, braking, forming, riveting, double seaming, ond soldering. Layout work is an important part of our work. The parallel line, radial line, and triangulation are emphasized. All types of fittings are developed by these methods, and by'the time we become seniors we are able to Icy out by one or more of these methods fitting for air conditioning systems, ventilation plans, warm air units, and ship yard work, The theory behind our work is taught to us in related science and related mathematics. In these we learn the scientific and mathematical basis of our work, ond memorize the formulae necessary to it. Soldering

For that reason, the younger students are introduced to both and their various branches. Thus he gets a view of the whole field, To provide for his choice we have two shops, the letterpress shop and the photo-otitset shop. In the first the boys learn the various kinds ot type, composition lboth hond and automaticl, the use of various kinds of power presses and the small iob presses, the difterent kinds of paper stock including cutting and cost estimation - all this under simulated shop conditions ln the sec- ond shop the boys learn camera work, plate making, stripping, layout, and the operation of the offset press. Both shops are provided with high speed multilith presses, a knowledge ot the operation ot which opens up jobs in many business houses. Our graduates in printing should be prepared to do apprentice work in any of the various fields of printing. Stripping lnserting Feedboard Micromete e su l Q at 'P' st? -N

Position Arc Welding New Shape Cutting Machine Qyefdirzq Sfwp With the development ot modern armaments and the increased de- mand for heavy goods, the need for competent welders has never been greater. Begihning with the use of the forge, the properties of metols, the handling ot heat, and the knowledge of hand tools, we of the welding department advanced to the use of machines: grinders, butters, shears. In the latter par't ot this process, much ornamental and useful metal work is performed by the older boys. During our training we leorned gas welding on light gauge metals, including copper, aluminum, brass, and stainless steel. We then advanced to welding on heavier materials such as cast iron, to gas cutting both by hand and by mochine Aaall with proper observance of the rules of safety In addition we learned brazing, silver soldering, the use of ordinary gas welding, and the higher speed heliarc welding for aluminum and stainless steel. Our shop has been completely renovoted in the last year. A complete paint iob has brightened the whole area, We have a new ventilation and air conditioning system, two new wash bowls, twelve new arc welding booths, two new heliarc units and the booths tor them, a new cutting machine, grinder, grill, and stock room, With the excellent course ot in- struction and with all this new equipment, most ot us should become ond, we believe have become good workers in the welding field, Oxy-Acetfiene We'ding Uni' Cutting Steel Slate
