Production. Milling machines and machine castings. Foundrymen make sculptures in sand more exact then many a work of art. Shown here is a rollover machine for small work. The pattern (left) is first placed face up, and the flask (iron cast on conveyor) placed over it. Special sand is tightly rammed into the flask; then this machine inverts the assembly and withdraws the pattern as shown, leaving a perfect mold. Location: a large Midwest machine tool plant

Production. Milling machines and machine castings. Fresh from the shakeout pit, where the mold is broken up and the sand sent back for reconditioning, new castings go to the core cleanout room to have the core sand removed with air and sledge hammers, vibrating machines and powerful hydraulic jets. Notice the core arbors sticking out of the sand. They are placed in the cores for the same reason that steel reinforcing bars are put in concrete floors and pillars. Each of these castings has by now become the body of a milling machine working for victory

Production. Milling machines and machine castings. A close-up of a milling operation on a large bed. Note the multiple-touch cutter, larger than an elephant's foot, turning at the left. Facing it on the other side of the casting is another cutter of the same size, milling the other side. Special fixtures and cutters are used for different shaped castings machined on this special milling machine, produced in a large Midwest machine tool plant

Production. Milling machines and machine castings. It's all a matter of relative angles and turning speeds. Properly set, this gear-cutting machine tool will produce any kind of beveled, spur, hypoid or other kind of gear. The small hypoid bevel gear shown partially cut in the center of the picture will soon become part of another machine tool after it has been heat-treated, ground, lapped and thoroughly tested and checked

Production. Milling machines and machine castings. After losing their cores and being sand-blasted, castings go to the cleaning floor. This workman was using a pneumatic chipping hammer which with rapid-fire, chisel-like strokes trims rough edges and cuts off the uneven, jagged strips where the two halves of the mold join.

Production. Milling machines and machine castings. Not only the materials which go into the cupolas, but also the core sand used in the production of high-quality iron castings must be rigidly examined and controlled. The whole problem is essentially one for the chemist and metalurgist, so the laboratory, literally part and parcel of the cupola building, is constantly checking and rechecking during every minute that iron is being melted and poured. Location: a large Midwest machine tool plant

Production. Milling machines and machine castings. When a full ladle comes along, there must be enough molds ready to take the whole load. Nowhere is Time so stern a master as it is in the foundry. Iron must be poured when it's right -- or thrown out, cooled, and returned to the cupola. Location: a large Midwest tool plant

Three-inch A.A. cartridge cases. Cartridge cases for three-inch antiaircraft shells are produced by a series of operations that transform a flat brass disc into a case ready for loading with propelling charge and shell. Between each operation there is careful washing to remove all scale and adhesion and to leave surfaces clean for later processing. The big Midwest plant doing the work is well equipped to handle it in stride

Good men, good machines, good materials mean good gears for the rear axles of halftrac scout cars now being produced for our Army in an Ohio truck plant. White Motor Company, Cleveland, Ohio

Albion Hotel, Lincoln Rd., Miami Beach, Florida. Lobby, to sculptures, at night

Aluminum casting. Shelf after shelf of aluminum castings on their way to the heat treating oven for low temperature precipitation treatment. These castings are for aluminum piston heads. Aluminum Industries Inc., Cincinnati, Ohio

Buffalo, New York. These huge machines cut and slice imperfections from steel castings, in this case, gun barrels. They are manned by a man and a woman helper in the processing department of Republic Steel

The South courtyard of the Harry S. Truman Federal Building which is the headquarters of the Department of State

Conversion. Farm implements to gun parts. A grinding operation is performed on a Bofors gun slide in a converted Midwestern farm implement plant which is also making marine steam cargo winches for the Maritime Commission

Aluminum casting. One of the skilled workers in an aluminum foundry pictured ramming the drag side of a sand mold. This foundry is producing aluminum equipment for Uncle Sam's war effort, under subcontract to other factories producing war items. Aluminum Industries Inc., Cincinnati, Ohio

Production. Milling machines and machine castings. If it isn't level, it won't work accurately. Milling the bottom bearing pads of a milling machine column casting. Location: a large Midwest machine tool plant

Removing cured tube from mold. As the tire molds are all-automatic, so are the tube molds. This one has just opened; all the operator need do is remove the finished tube and put in another raw one. Note the seam marks in the mold itself, which leave their imprint on the tube. Thus a seamless tube may appear to have a collection of many sections. Firestone (General) Tires, Akron, Ohio

Buffalo, New York. Symington-Gould, makers of tank, ship and railroad parts. Woman operator of a five ton crane picking up rough castings of truck train for railroads. She operated this same crane in the last war; in between was a housewife
