New Book for Gunsmithing Students & Professionals

Volume #4 in the Gunsmithing Student Handbook Series was released in spring of 2020, “Gunsmith Tools, Cutters & Gauges – A Primer”

This book is different than the other books in the series.  It does not really teach gunsmithing, instead it provides information that would otherwise be scattered far and wide.  Seldom in gunsmithing books does anyone explain tools, its simply assumed that the reader already has a pretty high level of experience or training.

This new book is a primer in the truest sense of the term.  In concise yet complete and illustrated form the author explains what the tools were designed to do and how to utilize them correctly. If you think this book is for beginners, that is only a small part of its value.  Most of the tool makers in the American gunsmithing market participated in the assembly of the primer.  Many gunsmiths learn from the school of hard knocks, that is unnecessary when a clear and concise instruction manual is available.

Kindle E book version of the Primer is available on Amazon.com .  You old timers probably just yawned, but the tech savvy smiths in the audience perked up.  We are told this is the only book in the series that is planned to be offered in eBook format.  Why?  The Gunsmithing Student Handbook Series is written for college level learning, the material is presented to aid gunsmithing students of all persuasions and experience to become competent and fluent in the language, tools and practice of gunsmithing.  So, the Primer will act as an ambassador for the series, the publisher is working with the companies the contributed to the book so that they can offer the eBook or print edition to their clients.

Reference charts and tables included in the book might make it worth buying all by themselves.

Headspace Gauge Interchangeability App is Here!

Our friends over a 4D Reamer Rentals LTD have come up with a free app, yes its yours to use with no strings attached, none at all.

This app does what apps do best, provide a simple way to get the information you need and have it handy on your device/phone at all times.  Right now it’s available only for Android.

The GaugeGuide App has now be banned by both Google Play and Amazon App Store.  Down load it just to piss off the anti-gunners…  LOL

Two search methods are provided for the user. Results that are displayed are for cartridges that include the information you entered, so it matters what you type in.  It’s true, many gauges are able to correctly headspace more than one cartridge.  Knowing which ones is valuable information for the gunsmith. From the search results select the result that is closest to your desired caliber, each result will show the gauges that are fully interchangeable with that result.  If you do not see what you are looking for check the other options that appear in the result.  If no result appears, it is likely that your caliber of choice does not interchange with any other caliber, I.E. it has caliber specific gauges.

Many gauges will have “details” (information) available that should be helpful in selecting the correct gauges for your desired use.

With either search method when your receive “Compatible Results” similar to the screen shot below:
