Machine Molding.
In well equipped plants machines do most of the ramming, turn over the mold, draw the pattern, and do away with much heavy lifting. Machine molders usually work by the piece, and must be active and quick to earn good wages.
Training.
Foundry work is taught in many schools, but only a few schools have been able to keep up with the industry in providing machinery.
PLAN No. 921. SHEET-METAL WORKERS
Demand for Workers.
The sheet-metal worker is the survival in modern industry of the village tinner or tinsmith, and the demand for these workers is large and increasing.
In the building trades, in ship building, in automobile and airplane construction, and in the manufacture of furniture, kitchen ware, heating and ventilating apparatus men of skill and experience in sheet-metal working are required.
What the Worker Does.
Workmen at the trade are mainly occupied in cutting out shapes or patterns, bending and forming these shapes on machines or with hand tools, and assembling the parts by hand. Edges are fastened together by riveting, soldering, or by lock seams. For example, a shaving-exhaust system consists of suction pipes, an exhaust fan, and a large pipe leading to the outlet, at which point is a dust separator called a cyclone. Practically all of the system is built of galvanized iron in sections, which are first constructed in the shop, then erected and supported in place in the factory where it is to be used. All of this work, including the erecting, is done by sheet-metal workers.
