There are many sheet metal books available that will show you how to make the duct-work for your home heating system. This book takes that knowledge a step further. It begins with a clear explanation of the basics in drawing, geometry and drafting and moves from there into solving common duct work problems.
The genius of this book comes in Parts II and III where you learn how to make roman moldings with complex miters, fancy roof ventilators in several different shapes and tapering shapes-like pyramids, cones and funnels. You also get the secrets of shape triangulation, which will allow you shift the shapes from round to oblong or from square to round. This book also includes patterns for skylights, a watering can and a three-dimensional sphere.
What does this mean to you? Well, if you apply some creativity, you can turn those ugly flat roof vents you currently have into a brass or copper cupola that will make your neighbors ask for one just like it! Install a skylight in the kitchen, or better yet, above your garage workbench! The possibilities are endless.
