...take a sheet 20 feet wide, has been developed by the Ralph C. Coxhead Corp. to enable a typist to letter engineering drawings and tracings. By reducing to one-tenth the time required for lettering, it cuts down drafting-room time more than one half, solves a bottleneck in war production...
...long last is ready to put the profit motive to work to get the big copper companies to increase their output of this bottleneck metal...
Aluminum capacity-the first fully recognized bottleneck of all-has been more than tripled since 1940, yet WPB's Requirements Committee could not find enough aluminum tubing to fill more than two-thirds of the demand for strictly war needs in the third quarter of this year. They also had to say no to one-quarter of the requests for extruded shapes (though supply and demand are almost together on sheets and forgings). But, by 1943, things should really look better, since the U.S. and Canada are scheduled to produce almost 50% more aluminum than this year...
Apprentices Wanted. The uncut boules are shipped to U.S. jewelers to be split, sawed, cut, drilled, polished for use as bearings. This stage remains a serious bottleneck. Reason: jewel cutting in the U.S. involves more handwork than in Europe, where it is a highly mechanized art. So far the best apprentice jewel cutters have been nimble-fingered seamstresses. Grumbled a master jewel cutter last week: "We have been called upon to do a staggering job without having time to develop the machine methods it took the Swiss 100 years to develop...
...Strip mills designed to make sheets ⅛ thick for Detroit have been converted to make 1¼-in. plate. This has upped plate capacity by more than half, from 8,400,000 tons to 13,200,000 tons. Plate has been and still is the worst bottleneck in the industry, for nearly 75% of the steel needed for ships is plate. > But many a layman overestimates the amount of steel needed in shipbuilding. A 10,000-ton vessel actually weighs about 4,000 tons—the 10,000-ton figure is its carrying capacity. The 8,000,000 tons of merchant...
