"Pictorial Textbook Of Engineering" is the textbook I wish I had when I took shops in high school. I mostly remember them as goofing off periods, and the instructors didn't seem to care. An outline involving this text might have changed that. You will find excellent info on the engineering metals, their properties and how to work them, you will find info on all the methods of working metals, take you through the production of a lathe, and covers the tools you will use, all clearly illustrated. Even the section "Chemistry For Craftsmen" is well illustrated to make some deeper concepts easy to grasp.
This vol. is 303 pages, so it will take 7 installments to upload the whole book. The quality is not perfect but better than many I have seen.
