关于此电子书
"Practical Pattern Making" by Paul N. Hasluck was first published in 1905. Written in simple, concise language and full of helpful diagrams, this timeless volume will be of considerable utility to anyone with an interest in designing and creating foundry patterns. "A foundry pattern is a counterpart of a casting and is used to form the mould into which the molten metal is poured. Patten-making is thus a very important part of foundry work, and the pattern-maker must be a craftsman of experience and of more than ordinary intelligence. The competent pattern maker has a knowledge of practical plane and solid geometry and of mechanical drawing; he is constantly required to lay upon an uneven angular surface, lines which the ordinary draughtsman can get much more easily on smooth surface of paper" Contents include: "Foundry Patterns and Foundry Practice", "Jointing-up Patterns", "Finishing Patterns", "Circular Patterns", "Making Core-boxes", "Coring Holes in Castings", "Patterns and Moulds for Iron Columns", "Steam-engine Cylinder Patterns and Core-boxes", "Worm Wheel Pattern", "Lathe-bed Patterns", "Headstock and Poppet Patterns", "Slide-rest Patterns", etc. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
