“Gunsmith Tools, Cutters & Gauges – A Primer” is Now Available


The fourth book in the Gunsmithing Student Handbook series, containing over 100 years of knowledge, is now available in paperback or eBook for all students of gunsmithing.

Kalispell, Mont. (August 2020) – Fred Zeglin, gunsmith, teacher, and writer, worked with the makers of gunsmithing tools, reamers, headspace gauges, and much more to create “Gunsmith Tools, Cutters & Gauges – A Primer,” the fourth book in the Gunsmithing Student Handbook Series. It contains a wealth of knowledge about how and why gunsmithing tools are designed and manufactured as they are. Many folks getting into gunsmithing, either professionally or as a hobby, need this jump start about the available tooling and the basics of its use. The book is out now and available on Amazon or from www.4drentals.com.

Consider that the information in this primer is assembled from the writings of people who best know these tools, including the manufacturers who make them. The school of hard knocks takes a long time to teach valuable lessons and this book can save you years and introduce you to some tools and concepts you were unaware of. Even old timers will pick up some valuable information; don’t continue through life believing “Wives’ Tales” when you can have facts.

Each book in the series provides a highly detailed and technical explanation of the subject at hand in a way that any gun lover will be able to understand. Other titles in the series include “Chambering Rifles for Accuracy,” “Chambering for Ackley Cartridges,” and “Understanding Headspace for Firearms.” These titles dovetail nicely with the new book as the subjects are all connected.

This is an old-fashioned primer filled with modern information about gunsmithing tools. Merriam-Webster defines a primer as “a small introductory book or a short informative piece of writing.” Teaching you how these tools are designed and made will make you more efficient and profitable as a gunsmith.

Zeglin commented, “People who have decades of experience with a job and it’s tools have a ‘curse of knowledge.’ In short, they have no idea how much of what they know needs to be explained to people with less experience. Even the terminology that we use requires defining. I think this book is a huge step toward breaking that curse.”

“Gunsmith Tools, Cutters & Gauges – A Primer” is ISBN-13: 978-0-9831598-6-5. The price of the book is $12.95 for paperback. The softcover measure 5.50” x 8.5” and contains 75 Pages. The eBook version is available on Amazon. eBook Version is ISBN-13: 978-0-9831598-7-2.


  1. In this series, looking at the titles, I would have thought this would have been the first book.

    I might just have to get a paper copy, unless DG reviews it and finds it wanting. (Ebooks are convenient, in many respects moreso than paper, but you don’t really own the books.)

  2. I own all of Fred’s books and they are, IMO, quite good. His book on wildcats is well worth its price, because there are lots of people who think they want to design a wildcat, but then get all pissy when a gunsmith gives them a price on the project.

    Get the paper copy. Books like these are what the anti-gunners will come after when they’ve learned that guns can be made without 3D printers. All electronic books, short of those you can download as PDF’s, are subject to being taken away from you by licensing schemes.

    There are many books on guns and associated topics on archive.org. You can find both Vickery’s book and Howe’s two-volume work there.

    I’ve started work on a book on gunsmithing, starting from literally where many millennials start: not knowing the difference between a screwdriver and a chisel. I hope to finish it before I snuff it. 20+ years ago, I would have been content to merely refer those interested in such things to Vickery’s book or other well-known books on gunsmithing.

    Sadly, this is no longer possible. The feminist ‘revolution’ (more like ‘de-evolution’) has brought forth a couple generations of men raised by single mothers who know not how to use even the simplest hand tools properly. As such, I am finding it necessary to discuss in my book the very ground-level basics, starting with the fundamentals of steel.

    • I look forward to reading your book.

      The approach you suggest is actually warranted, I think, not only because millennials, but because even people you’d expect to know better can have unexpected gaps in their knowledge base.
