INTRODUCTION
Some gunsmiths say that reblueing a firearm with the “hot salts method”
is what sets the professional gunsmith apart from the amateur gun “tinkerer.” Almost anybody can take some sandpaper and some oil finish and
refinish a worn gun stock. It takes a dedicated, trained professional to
equip and operate a shop capable of professionally refinishing gun steel.
Not all gunsmiths choose to do their own blueing. To many gunsmiths,
however, the most rewarding aspect of gun work is making the worn,
faded, or even rusted finish on a firearm look as good as, or maybe even
better than, new.
Blueing or reblueing firearms can also be a very profitable aspect of gunsmithing. Once you obtain your basic disassembly hand tools, polishing
equipment, and blueing tank, the actual cost of material for blueing is
minimal. With the black oxide process, the chemicals are reusable. You
need only to add a few more pounds of “salts” whenever you begin heating the tanks for a blueing session.
SUGGESTED EXERCISES
We based this practical exercise on Gun Parts Corporation’s catalog.
Whether you’re going to specialize in general gun repair or occasionally
need a part for a gun you bought for resale, eventually you’re going to
have to know how to locate parts for old guns. Gun Parts Corporation is
the world’s largest supplier of gun parts. In many cases, especially for
some obsolete firearms, they’re the only reliable source of parts. You
must learn to use the catalog to identify and order the correct parts for
various firearms. Your successful completion of this exercise will show
that you have working knowledge of the catalog.
Activity 1: Design a Blueing Shop Setup
The old business adage, “time is money,” still holds true for a modern
blueing operation. When blueing, the way to save time is to operate efficiently. To operate efficiently, you should have a well-designed work
area and the proper equipment.
The most popular professional blueing method is the black oxide method
that’s also called the hot salts method. For this activity, we’ll concentrate
on the hot salts method, although you can adapt the method to many of
the other procedures discussed in your textbooks.

reassembly, and storage areas.
Activity 2: Buy an Inexpensive Military Surplus Rifle to Sporterize
Gunsmithing is a skill, and like any skill, the more you practice, the better you’ll get at it. A great way to get this practice is to sporterize a military surplus rifle. Sporterizing a military rifle usually encompasses most
of the general and specialty skills that gunsmiths use today.
You may use some or all of the following skills when sporterizing a
military surplus rifle.
• Disassembly/assembly
• Cleaning
• Tuning the action
• Adding and fitting improved parts
• Drilling and tapping
• Scope or sporting sight installation
• Bolt alteration
• Trigger/safety work

• Stock fitting and finishing
• Reblueing
• Rebarreling
There are many relatively inexpensive military surplus guns currently
imported. While some of them have collector interest and should be left
in original condition, you can make most of them into acceptable, if not
elegant, sporters.
Mausers are indisputably the king of military bolt actions. Professionals
consider the large-ring, German-made Mausers the best of the these.
However, there are many other rifles that you can transform into suitable
“venison getters.”
Some prized rifles to sporterize are
• Large-ring, German-made Mausers
• U.S. M1917 Enfields
• U.S. M1903 & M1903A3 Springfields
Also acceptable are
• Small-ring, Swedish Mausers
• British Enfields
• Japanese Arisaka
• Italian Carcano
• Finnish or Russian Moisin Nagant
Of course, you should do some research before you decide which rifle to
choose. Some sources of information include
• Monthly gun magazines to find articles on surplus rifles
• Shotgun News to see what surplus guns are currently available
• Local gun shops for a selection of guns
• Gun shows for a selection of guns
Additionally, you should consider the following before you select a
model of surplus rifle.
Availability. What guns are currently available on the market?
Price. How much are you willing to spend for the gun and the accessories?
How much of the work can you do yourself? How much will you have to
pay someone else to do the work you can’t do?
Caliber. Is ammunition available at a reasonable price? A good deal on a
rifle may not be such a good deal if ammunition isn’t readily available or
if it’s very expensive.

Barrel. What condition is the barrel? With the hand tools available from
Brownells, you don’t even need a lathe to precisely install a semifitted
barrel to a Mauser action. Do you want a new barrel in a new caliber?
Stocks. What stocks are available?
Scopes. How difficult is it to mount a scope on this rifle? Are scope
mounts available? Does the bolt have to be altered? What about safety?
Iron sights. Are sporter sights available? Do you need or want iron
sights?
Reblueing. The finish of the metal surfaces is probably worn and needs a
reblueing. Do you want high-gloss or matte blueing?
Trigger. Do you want to add an adjustable trigger to your custom rifle?
Gather Additional Information
Contact various manufacturers and suppliers for the availability, styles,
and prices of various replacement stocks. Drop-in synthetic stocks, semiinletted walnut blanks, or walnut planks are available for most, if not all,
of the surplus rifles.
Check your Brownell’s Catalog for accessories for various military rifles
and contact accessory manufacturers for catalogs.
Conclusion
Your project rifle can encompass all of the riflesmithing skills that you’ve
covered in your Gun Pro course. When you finish, your rifle will be tangible evidence of your skill and professionalism. It will be something you
can use and display with pride.
