Gunsmithing Compendia
Master List
I want to create as comprehensive a knowledge base on gunsmithing as possible. I want to do this for several reasons. First, I want to learn as much as possible. Second, I want everyone else to have the resources to learn as much as they can, want to, whatever. Third, I want to preserve as much information as possible for the gunsmithing industry’s future use.
This page is the master working document where I collect the data, information, and knowledge I have gathered so far. So, there are broken links, bad grammar, poor spelling, and fragmented sentences. The alphbetization is often out of order. I am working as best I can. Unless you are willing to assist, be kind.
How it works:
I have found that every item gathered is one or more of the following: person, place, object, action, event, or idea.

accuracy
jargon
Accuracy is a measurement of the ability of a firearm to have the point of aim as close to the point of aim as possible.
See also mean radius, precision
accuracy life
jargon
In my book, accuracy life boils down to the practical lifespan of a firearm, gauged not by catastrophic failure, but by the degradation of its inherent precision. It’s the estimated—or better yet, rigorously tested—round count a specific rifle or handgun, chambered in a particular caliber, can reliably send projectiles within a defined accuracy standard. Don’t get any romantic notions; this isn’t a fixed number etched in stone. The ferocity of the cartridge, the consistency (or lack thereof) of the ammunition, the cadence of fire, the diligence of maintenance, and the very engineering of the firearm all play a significant hand in how long that sweet spot of accuracy endures.

accurize
jargon
As found in the SAAMI glossary, the definition of accurize is “The act of subjecting a firearm and its components to special fitting and operations with the goal of optimizing accuracy.”

action
jargon
In Ruling 93-2, the ATF defined a firearm’s action as “that portion containing the breech mechanism by which the firearm is loaded, fired, and unloaded and includes the frame or receiver.”
PLEASE NOTE: The stated purpose of Ruling 93-2 is to tell us that a ‘barrelled action is not a firearm for purposes of the manufacturers excise tax on firearms imposed by section 4181, Title 26, U.S.C.” To my knowledge there is no other published definition of ‘action’ by the ATF, and this ruling provides a formal and often-cited definition of “action” that doesn’t mean it is the primary definition used by the ATF.
In the SAAMI glossary, a firearm’s action is defined as “the combination of the receiver or frame together with the other parts of the mechanism by which a firearm is loaded, fired[,] and unloaded.”

accelerator
part
An accelerator is part of a firearm action that speeds up its function by transferring kinetic energy from one part of the mechanism to another.
For example, during the unlocking phase of the cycle of operation, the barrel extension in an M1917A1 Browning Machine Gun strikes the accelerator, causing it to rotate to the rear. As the accelerator rotates, it hits the bolt, speeding up its movement to the rear.

The Handloader's Manual of Cartridge Conversions
book
With the release of the Fourth Edition, The Handloader’s Manual of Cartridge Conversions offers a robust compilation of data for handloaders interested in creating cartridge cases beyond standard offerings. The manual provides the necessary physical specifications, procedural guidance, tooling considerations, and dimensional drawings for converting commonly available cartridge brass into over 1,000 different rifle and pistol case types. This includes information about obsolete cartridge patterns and contemporary “wildcat” designs.
This revised edition emphasizes ease of use with a new organizational structure and a comprehensive index of the numerous cartridges detailed within. The primary focus of this manual is to equip the handloader with the technical knowledge required to undertake cartridge case conversions using modern, readily sourced materials. It is a central resource for producing specific or non-standard cartridge cases for various firearms applications.

in the white
jargon
Being in the white means that a metal part has no coating on it. It has not been anodized, blued, parkerized, Cerakoted, etc. As such, it is vulnerable to environmental conditions and prone to oxidation (rust). For example, if a blued gun barrel has a dovetail machined into it, the exposed silver-colored area is said to be in the white.
This phrasing comes from gunsmiths’ (and the blacksmiths who came before them) association with whitesmiths. A whitesmith is either a craftsman who makes, repairs or modifies things made from pewter or tin or a craftsman associated with finishing or polishing iron before it is browned, blued, etc. Thus, metal just before it is ready to finish (browning, bluing, etc.) is said to be in the white.

Warren Kempton Page
experimenter, shooter, writer
…
From the New York Times, January 24, 1977, Page 25,
Warren Kempton Page, the former gun editor of Field and Stream magazine and a member of the Hunting Hall of Fame, died Saturday in New Canaan, Conn. He was 67 years old. Mr. Page had left the magazine about six years ago after 24 years there. At the time of his death, he was the president of the National Shooting Sports Foundation, which he founded. As a hunter and outdoorsman, he had won the Weatherby Big Game Trophy, founded the National Bench Rest Rifle Championships, and was active in a score of hunting and allied organizations. On safaris in Africa, India, and Australia, and other sites for the big game, Mr. Page “shot most everything in the book,” according to Hugh Grey, the former Field and Stream executive editor, who hired Mr. Page in 1947.
Trophy Is Highly Regarded
Referring to the Weatherby Trophy, Mr. Grey said: “This is no Boy Scout award. You really have to have accomplished something in the hunting field to have won it.” Mr. Grey also credited Mr. Page with having been a “very good‐editor.” He had a “tremendous” following, Mr. Grey said, and he had been “very innovative.” “He was most unusual in knowing. as much about the technical side of his job as the hunting and shooting aspects,” Mr. Grey, said.
Mr. Page was born in New Bedford, Mass He was a graduate of Harvard University, class of 1931. Following college, he taught at Lawrenceville School in Lawrenceville, N.J. In World War II, he was a Navy lieutenant and a gunnery instructor.
Mr. Page belonged to the National Skeet Shooting Association, Alaska Big Game Trophy Club, African Wildlife Leadership Foundation, Ducks Unlimited, Campfire Club of America, Alaska Professional Hunters Association, Bench Rest Hall of Fame, and the South Dakota Ringneck Club.
In addition, he was co‐commissioner for North American game for the Conseil International de la Chasse.
He is survived by his wife, Martha Lutz Page; a son, Kempton H.; a daughter, Kathleen P. Wasiuk, and a grandchild.

This pistol uses 53-grain .31 caliber ‘rocket ball’ ammunition, which requires less than six grains of black powder per shot. The price of this gun was approximately $12.
