I use Machinery's Handbook for its tables, formulas, and section on properties of materials.
The purpose of the Machinists and Tool Makers Handy Book is: "To provide a complete course of study for those desiring to become machinists, and to help machinists become tool makers".
For the paper work, go to Machinery"s Handbook. If you need to do single point threading, or make use of a plunger back dial indicator, the Audels book is the one.
My Aristo Multilog can still do the job, after all these years.
