I know this is OT, but I think it is still an appropriate subject for many of the guys out there (like me) that are into the fabrication side of things. I thought we could get a list of important books going that we believe are worth reading. I go through a lot of books trying to find good textbooks or reference books for my classes. The vast majority of these books suck. Don't get me wrong there are some awesome books out there, but most are either too basic and don't provide anything other than a very shallow overview or they are too in-depth and written in such a way that a normal person would need to have his dictionary and scientific calculator out just to get through the first paragraph. Metalworking: Sink or Swim by Tom Lipton - This book is like having a master machinist and fabricator with you. Detailed COLOR photos on several setups and just a ton of tips for milling, turning, welding, sheetmetal work, etc. I don't care who you are, there is something valuable for you in this book. I've been in the trades for years and there is a technique he shows you on a manual mill that I did not know was possible. This is one book I would not pass up on. It is written in a fun, easy to understand, and enoyable way that makes reading it a pleasure. Lots of good technical info and funny stories, too. Metallurgy by B.J. Moniz - This is hands down the best metallurgy book I have ever read. It was recommended to me by Fay Butler. It is a good foundation for anyone interested in the metals trades. Most metallurgy books are written for a metallurgist and quickly go straight into a LOT of math (and not just college algebra ). This book is written so that you get all the information you need and you can understand it. Some texts are written in a style that I believe is delibrately confusing. The writing style for this text is such that any intelligent person can easily comprehend it. Machinery's Handbook - If you are into machining and DON'T have this book, then you really aren't into machining. MUST HAVE. Charts and technical information out the wazoo. The secret to life is in this book - if I can only figure out what dang page it is on. There are a lot of others, I just thought I'd start this off with these three and hopefully other folks will contribute other titles that they have benefited from. If these is too OT, I apologize and ya'll can delete it. I just see a lot of questions about stuff and think that some of these guys might need these books.
