Query: A Very good reference book.

This book contained a lot of info that I already knew and some I didn't. I found this book structured for an easilyreed. There is a huge section on data and charts as all machinist book are, this describes tooling in a very easy way to comprehend. If you were a very beginner and completely new at machining, THIS should be near your toolbox. This book even has some good start up small projects(some of them are tooling)that beginners can use to familiarize them selves with machine use. I believe this book would be good in a vo-tech precision machining course as a student handbook.
