Lanny,
Yes that George Thomas book is really good. I gave my first one away to my nephew and immediately ordered a replacement. I can't think of a better referance book other than Machinery's Handbook that's as good. $80.00 for used? That's a joke, Google "Hemingway kits" or "Tee Publishing" in the U.K. You should be able to get that book including shipping for about $40.00 U.S. and that's for a brand new book. I refuse to be responsible for the monetary drain on your wallet if you unwisely decide to view the Tee Publishing website though. One tip, Book shipping from the U.K. can add up fast. It's far better to save up and order multiple books on one order as the shipping costs go down on a per book basis if you order 4-10 books at a time. LOL, My last book order was almost $800. I now have pretty well most of what interests me from the Tee website. I'll go as far as saying that $40.00 will be the best you'll ever spend on a book that will answer and help you understand a vast ammount about hobby type machining. Besides the factual information about various machining procedures, The book deals with a lot of improvements and accesories for Myford lathes. But most or all could be reworked to fit almost any lathe. IMHO, George Thomas was a master at the subject and had the rare talent to not only know the subject hands down but had the rare combination of also being able to clearly write about it.
To be accurate though I just got an email yesterday about this book. George started to write this book and became too ill to finish it. A Bill Bennett took what George wrote, Edited and added to it. George's other book "Workshop Techniques" is also well worth buying but it deals with building the universal pillar tool, And the Versitile Dividing Head. But it's well worth having even if you never build that equipment just for the machining examples.
