HG IV Circular Work in Carpentry
This book is a subset of the Holy Grail of Roof Framing Geometry & Trigonometry books.
The book includes step-by-step instructions on developing stereotomic double curvature drawings for circular work in carpentry. Some of the techniques presented in this book are thousands of years in the making. As carpenters, we shouldn't have to re-invent the wheel each time we are faced with new challenges. There is a likely hood that someone, that came before us, has already refined a technique that we can use today. The tools might have changed, but the piece of wood that it is twisting and turning remains the same piece of wood.
This book also includes a zip file download of 930MB. There are some print, scribe, and cut drawings for double curvature in the zip file download. As, well as, PDFs, pictures of the process of cutting the wood, SketchUp files, and some AutoCAD files.
