‘Simplified Tables and Formulas for Designing, and Practical Points in Cutting All Commercial Types of Gears’. This has to be the BEST in-print book we have seen on actually designing gears of every imaginable type, with clearly explained principles and detail formula for each form. The ‘practical points’ on cutting gears are interesting, and have potential use, but, as is explicit in the sub-title, are aimed at commercial gear cutters. However this is still undoubtedly a book anyone cutting gears should have on their bookshelf. 353 pages, with tables, formulas galore, engravings of set-ups, tooth-forms and the like. Paperback.
