Condition & notes
In Good condition, no dust jacket. Orange-tan cloth boards, black lettering and rule borders on front board and spine, printer's ornament to front board. Mild to moderate shelf and edge wear, nicking to cloth along the bottom edge of the front board, mild to moderate scuffing and soiling overall, heavier along spine with fraying at head and foot. A thin crack between pp. 408-409, but binding is still sound and tight. Soiling to endpapers and to the copyright page, with occasional light spotting and soiling to the text, consistent with shop use. Otherwise unmarked. Cincinnati Milling was the largest plant in the world given over to milling machines and cutter grinders, and says so here: 810 feet of machine shop, eight acres of floor space, visitors cordially welcome at all times. The treatise is part textbook and part self-portrait. Its preface claims matter never before published, and the chapters on shop trigonometry, continued fractions and spiral and bevel gears are based on material prepared by A. L. DeLeeuw while chief engineer of the firm, with gearing formulas taken from Machinery's Handbook by permission. Dated 1916, it catches the American machine tool trade on the edge of war production: one fixture mills aluminum magneto bases at three to four a minute, another holds thirty-seven spark plugs at a time. Priced $1.50 on the title page. Eighth Thousand is an impression statement, not an edition: eight thousand copies had gone into American shops by the time this one was printed. The Library of Congress holds the fourteenth thousand, dated 1922 and expanded to 441 pages, which places this copy somewhere between 1916 and 1922.
