Triangulation - Applied to Sheet Metal Pattern Cutting - A Comprehensive Treatise for Cutters, Draftsmen, Foremen and Students: Progressing from the Simplest Phases of the Subject to the Most Complex Problems Employed in the Development of Sheet Metal Patterns with Practical Solutions of Numerous Problems of Frequent Occurrence in Sheet Metal ShopsThis vintage book contains a detailed guide to triangulation as applied to sheet metal pattern cutting, originally designed for the use of cutters, draughtsmen, foremen, and students. With detailed diagrams and a wealth of useful information, this volume will be of considerable utility those with an interest in sheet metal work. Contents include: "Elementary Principles", "A Simple Transitional Fitting", "The Oblique Cone", "A Transitional Fitting From Rectangular to Round Which Makes an Offset", "A Twisted Transitional Fitting", "The Pattern for the Frustum of an Oblique Cone", "A Transitional Fitting From Oblong to Round", et cetera. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern edition complete with a specially commissioned new introduction on metal work. First published in 1917. |
