The book Machine Shop Trade Secrets is an excellent source of tips, tricks and common sense articles on primarily machine work, tools and setup. I believe almost every person that uses this site would benefit from having one. I have no relationship with anyone connected to it, however, I am a voracious reader and have a fairly extensive library. I refer to this book a fair amount and have read it several times. As always when book shopping try EBAY first, even if you don't like them, and then AbeBooks. Brian.
