LOCK ASSEMBLIES
Percussion Lock Assembly
(For Lyman Great Plains, Trade and Deerstalker Percussion Models)
The percussion lock on your Black
Powder Rifle is a near-perfect blend of
both old and new. The exterior is finely
finished and color case-hardened as were
the guns of 150 years ago.
Inside, the lock is a redesigned system
featuring a coil mainspring (42) instead of
the traditional leaf spring. This is a much
more durable mainspring, one that is 
not prone to the breakage problems
encountered...

LYMAN PLAINS PISTOL
Lymans Plains Pistol recreates the trappers pistol of the mid-1800s while incor-
porating the best of modern steels and technology.
All steel parts on the finished gun are polished and blued - except for the belt
hook.  The percussion lock is hardened internally with a color-case hardened
lockplate and hammer on both the kit and finished gun.
Your Plains Pistol is designed to fire a tightly patched roundball accurately at
various charge levels.  Do not shoot conical bullets, such...

Instructions for Lyman
Assembly Kits
INTRODUCTION
The materials provided in Lyman Kits have been selected for their overall
quality and durability.  Proper assembly will enable you to create a muzzle-
loading firearm having the quality lines of an expensive custom piece.
Read these instructions thoroughly before you actually begin assembly.
There are several critical steps - and others that will save considerable time
within the instructions.  Reading the instructions will give you a better under-...

Example:Assume that you are inletting the lock assembly. After you remove
the lock for the first time you will note the black transfer marks in the cavity.
Little black will be apparent around the edges of the lock. Black marks will be
located within the cavity showing where wood is to be removed to allow the
working parts of the lock to fit. You will continue to coat the part with transfer
agent, reinsert it into the cavity, continue inletting gradually dropping the lock
into place. As the lock is...

2. Fitting the Tang to the Breech Plug–The tang and the lug on the breech-
plug may require hand-fitting to provide the proper fit when the barrel is
hooked into position. The fit described below will assure a rigid barrel/stock
assembly that will promote excellent accuracy in the finished rifle or pistol.
Caution:This step is often unnecessary as it is factory fitted.
You will note that when the tang is first installed onto the breech plug it may
not lie flat, in contact with the rear of the breech...

5. Inletting the Lock Assembly–First, draw the hammer back to full cock.  Apply
transfer agent to plate edges. Position the lock over its cavity in the stock. Insert
the lock mounting screw and slowly tighten it, drawing the lock down into posi-
tion. Draw down only until resistance is met. Remove the lock and examine the
cavity for black transfer marks. Carefully cut away excess wood.
NOTE: If you remove too much wood from the inner surface where the stock
and the edge of the lock plate meet,...

37
NOTE: Gap between lower barrel flat and bottom forend channel should not
exceed 1/16.
At this stage you should complete inletting of the lock to its full depth so the inside
shoulder of the lock makes solid contact with the side flat of the barrel, and the bol-
ster of the breech plug fits properly into the circular cutout of the lock. Install the
lock assembly. Blacken the underside of the bolster and reinsert the barrel assembly
in the stock. The barrel may not go back into its fully inletted...

38
The trigger guard should be left on the stock during all stages of wood shaping and
finishing. However, the correct fit is flush with the finished stock. After the stock has
received its final sanding, the trigger guard can be removed for final polish and later
installation on the stained and finished stock.
10. Inletting the Butt Plate (Rifles Only) and Forend Cap–Both the butt plate and
nose cap have been factory-installed to protect the exposed ends of the stock.
Additional fitting may be necessary...
