Some engineers at the General Electric Company's Aircraft Gas Turbine Division here make a career of splitting hairs. However, their purpose is not to be argumentative but in the interest of accuracy to within one-thirtieth of human hair. Such accuracy is practiced by GE engineers in huge jet engine plant's Measurements Standards Laboratory where they have the responsibility of keeping all master gages, master gears, and measuring rods completely accurate. These measurements tools are used in the production of J47 and J73 jet engines for the Air Force and Navy. Above GE engineers Frank L. Riley (right) and Jack Morgan (left) work with their latest aid in search for accuracy, a Universal Photograph machine. The machine can measure accurately to within one ten-thousandth of an inch the size, shape, and thickness of jet engine parts.
