SDI Firearm Finishes and Engraving
(FTT 201)
Nickel plating has been a popular finish for handguns and certain small parts of long
guns since the turn of the century. The finish is applied by a process called: -
✔️✔️Electroplating
When using a wheel for polishing: - ✔️✔️Always polish with sharp edges pointed in the
same direction the wheel is turning.
Which of the following wheel types used in machine polishing will cut the fastest? -
✔️✔️Felt
Lands in the throat are which are uneven in their short points are usually caused by: -
✔️✔️Cleaning Rod Damage
According to Joe Carlos, what must you do with a barrel to know for certain what its
current capabilities are? - ✔️✔️Shoot It
T/F: The electropolishing process both improves barrel accuracy and is safe for the
environment. - ✔️✔️FALSE
Joe Carlos' experiment showed that electropolishing was: - ✔️✔️Effective for
Increasing the Accuracy of Damaged Barrels
The fire lapping process involves: - ✔️✔️Firing cartridges with progressively finer grit
abrasive coated bullets, which effectively polishes the bore.
T/F: Fire lapping has about the same average effective improvement on accuracy as
electropolishing. - ✔️✔️TRUE
T/F: One possible indicator that a barrel is likely to shoot poorly is pitting near the
crown. - ✔️✔️TRUE
There is generally more need for fire lapping in: - ✔️✔️Button Rifled Bores
T/F: Fire lapping does not remove metal from the barrel. - ✔️✔️FALSE
, "Throat maintenance" bullets were found through extensive testing to: - ✔️✔️Have a
reliably positive impact on accuracy
The two basic metal preparation processes, according to Frank Fry, are: - ✔️✔️Hand
and Machine
The first of three steps to hand finishing is: - ✔️✔️Remove machine marks with files
To prevent the loss of or "pulling" of letters and numbers, these areas should be
polished by: - ✔️✔️Hand
If stamping has been damaged or pitted, you should: - ✔️✔️Leave the damaged
stamping alone
For basic polishing: protect all of the newly-polished surfaces from rusting with which of
the following until you are ready to apply the bluing solution: - ✔️✔️Light Coat of Oil
In general, power polishing entails starting which of the following grits and polishing the
surface of the metal in a given direction: - ✔️✔️Coarset
Power buffing: When using a bench grinder, one end of the double ended shaft contains
a conventional grinding wheel, while the other end has which of the following: -
✔️✔️Muslin Buffing Wheel
There are four popular methods of finishing gun metal prior to bluing, plating,
parkerizing, and the like: hand polishing, power buffing, mass finishing, and which of the
following: - ✔️✔️Sandblasting
Besides keeping the metal free of oil, which of the following is the most important step in
obtaining a rich, velvety finish on your gun parts? - ✔️✔️Polishing
When polishing, be careful not to polish out which of the following, and other lettering
that is found on the typical firearm? - ✔️✔️Serial Numbers
While polishing or draw filling, it is important that all screw holes are maintained at the
proper taper and that the holes do not become: - ✔️✔️Funneled
Which of the following seems to be the most critical task involved in restoring valuable
firearms? - ✔️✔️Metal Refinishing
T/F: Although it is a normal practice in gun shops, using the lathe for polishing and
grinding is recommended. - ✔️✔️FALSE
