Here, from 1942, you get a small, straight-to-the-point lesson in using a dividing head. Although the book is probably applicable to any indexing head, you get illustrations of a classic Cincinnati indexing head in operation.
Chapters include direct indexing, simple indexing, differential indexing, block indexing, compound indexing and graduating.
Within the chapters are lessons that include indexing for spaces with direct indexing; cutting reamers with unequally spaced teeth; high-number index plates on 5 to 1 ratio indexing attachment; the hypoid-indexing attachment to index for degrees, minutes and seconds; differential indexing with compound gear train; and much more.
Well illustrated. With all those "complicated" fractions fully explained. So if you have an old indexing head and don't know how to use it, or are planning to build the one Dave Gingery's describes in "Deluxe Accessories", you need this.
