Get yourself a "Pocket Reference" book by Thomas J Glover. I see them at the local hardware store, and should be available on line somewhere if you can't stumble across one in a book store. About a 3" by 5" paper back book withh 542 pages of just about anything you'll ever need. A Machinist Bible or Handbook is handy to have. They are expensive new, but can be found used just about everywhere. It is full of useful information also. Then there of course is the internet but the Pocket Reference book fits in a tool box where nothing else will and no need for Wi-Fi!
Type at you later,
