Most of the available books are older works that show techniques that really aren't acceptable to todays customers.
These are the old "get it to work....somehow" techniques involving heating and bending, silver soldering, and making expedient parts.
Today, a customer who gets his gun back with some of the old "hack work to make it work" techniques would sue.
The best books currently available are the Jerry Kuhnhausen shop manual series.
Kuhnhausen was a master gunsmith who also trained new gunsmiths for the industry, including the gun companies.
For that reason, he taught only the factory type techniques to restore guns to factory condition.
The Kuhnhausen books are written as shop manuals on a specific brand and type of gun. These show complete factory style gunsmithing operations and cover everything.
While these don't get into basics like how to operate a file or screwdriver, they do show how to actually gunsmith a specific gun.
There are also video tapes to go with the books.
These are an excellent start since you can sit down with a gun and the Kuhnhausen book and disassemble it and learn HOW it works and how to work on it.
These are NOT just the usual reprints of old ordnance manuals or the usual short articles from gun magazines, these are real technical manuals.
