Made during WWII by the U.S. Office of Education, part of the Federal Security Agency, this training film was one of a series used to educate wartime factory workers. This particular film demonstrates how a machinist should read and use a blueprint to finish making an iron casting. The machinist is variously shown studying the blueprint at a work desk, comparing the blueprint to the casting in progress, and checking measurements both at a work desk and while the iron casting is on a machine being finished. Production credits: “Machine Shop Work - Fundamentals of Blueprint Reading, No. 3 Principal Dimensions, Reference surfaces and tolerances.“ “United States Office of Education Training Film / Federal Security Agency” (0:07). Credits–Produced by Division of Visual Aids, U.S. Office of Education (J.W. Studebaker, Commissioner) and Federal Security Agency (Paul V. McNutt, Administrator) (0:16). Main title again (0:30). Lone white male machinist holds blueprint in workshop (0:40). Blueprint for finished iron casting (0:51). Closeup of machinist’s hand holding blueprint again (1:01). Machinist sets blueprint in front of him, begins following instructions for circular iron rough casting; machinist gesturing; machinist compares blueprint to object (1:05). Blueprint again, image of cast placed on top of blueprint to show scale correlation (1:24). Visual demonstration of cross-section; blueprint with casting alongside (1:45). Dimension line on blueprint showing diameter (2:05). Image of object with labels of cast iron before and after machining (small size change in object after machining) (2:11). Machinist in workshop holding cast iron, measuring object on table by hand with ruler, blueprint visible behind (2:40). Blueprint—“f“ sign on cross-section blueprint to indicate finishing needs; also thickness marked on blueprint (2:48). Closeup: machinist’s hands measuring thickness of cast iron (3:10). Thickness on cross section blueprint again with various arrows pointing to finishing symbol, thickness dimensions, etc.—step-by-step instructions of how to read blueprint (3:18). Hands of machinist in workshop measuring multiple dimensions of rough iron casting with ruler, blueprint behind (3:33). Blueprint section noting inside diameter dimensions of casting (3:40). Machinist demonstrates dimensions of inside diameter of casting (3:48). More blueprint views (3:58); machinist measuring the hub (4:22). Machinist with upper body visible studies blueprint and rough casting in workshop (4:28). Rough iron casting instantaneously transforming into finished casting, surface by surface (visual demonstration) (4:38). Illustrations overlaid on casting image to indicate correct finishing order of iron object, work in progress (5:08). Iron casting being finished by machine with machinist observing (5:31). Tolerance specified in blueprint (written note displayed, with fractional and decimal dimensions) (5:50). 8-inch diameter, diameters (bore, counter-bore, flange) noted on blueprint (6:08). Machine cutting again (6:41). With semi-finished casting on machine, machinist measures object on machine by hand; machinist reaches to check diameter of object on machine with caliber; finishing machine spins object (6:58). Machinist studies blueprint pinned to toolbox, gestures with ruler (7:12). Closeup: machine drilling hole into iron casting while spinning (7:34). Blueprint for comparison of drilling needs (7:40). Machine tool puts finishing touches after drilling (counter-boring, reaming); various close-ups of finishing process for iron cast (7:58). Machinist’s hands using tools to check diameter while machine is paused (8:20). Closeup of tool—cylinder bore gauge (8:28). Tolerance note on blueprint again (8:38). Split screen comparing machined object to blueprint: two rulers and cylinder gauge measuring dimensions of iron and blueprint after finishing (8:41). Closeup: machinist’s thumb holding cylinder gauge, measurement (9:18). Machinist (upper-body, viewed from above) holds and studies blueprint, toolbox in background (9:38). Machinist holds rough work piece, checks blueprint and compares to casting (9:45). Visual of rough work piece / iron casting again but alone against blank surface (9:59). Closeup: worker’s hands checking measurements of partially finished work piece (inner diameter - cylinder gauge) (10:10). Tolerance specified (10:28). Worker studies blueprint lying on open toolbox (machinist’s body/face partial view), pointing with finger (10:40). Produced by Atlas Educational Film Company.
