5 stars for indeed, the book deals with assemblies, and treats the subject thoroughly. It is perfectly done, but we must keep in mind that these are just * that * the possible connections between two pieces of wood You will learn a lot of things within this framework and one day you will build something and you find yourself stuck, or you want to do something that seems complex, this book will probably be the Holy Grail! A counselor at all levels: I am a beginner, and I learned a lot, but I think that a professional has not systematically all joints at the head and one day or another, the memory is refreshed always something substantial (I know what I mean (smile)). Small or large objects to build, this book may be necessary if you want to build a lot of wooden things!
