Make tools, fittings, and small metal pieces used in other products.
Tests pulverized material and computes specific gravity, using manometer tube: Collects mill samples, weighs specified amount of pulverized material, and pours it into cylinder and taps powder into compact mass. Raises mercury level in left side of manometer tube by pumping air into right side, using hand pump. Inserts cylinder of pulverized material into top of left tube. Releases air pressure from right side and times drop of mercury level in left side, using stopwatch. Computes specific surface of material, using standard algebraic formula. Reports below-standard reading to mill operator. May test milled sample of aluminum alloy to identify metals in sample and be designated Quantometer Operator.
