Inletting The Triggers:

Before the triggers can be inlet on a non-precarved stock, you need to determine where the triggers are going to be aligned with the lock. First place a mark on the face of the stock where the sear is located. Then you align the set screw of the triggers with the set screw. This ensures you have the cross over of the set trigger and the front trigger localized. Then I measure the depth of the wrist and which is 1-24/32" (Note, I measure everything in 32nds.  My shop ruler is in 1/32" so this keeps things simple.) I use this measurement from the comb forward to the tail of the lock. At this point I want the front of the trigger plate to align with a line that is parallel to the stock edge along the barrel.

I identified the depth of the barrel and with a 1/32" hole drilled into the bottom flat of the barrel channel, I can use my special tool to measure the depth of the ramrod channel. I then transfer this to the outside of the stock. Now I know how much wood I can remove without jeopardizing the ramrod hole I drilled into the stock.

Then I added 1/16" of wood to the belly. This is the red line in the photo. I verified to make sure I had 1/Cut Trigger Plate.jpg (168700 bytes)8" of wood above the entry hole for the ramrod to inlet the rear thimble.

I figured since I had to shape the belly of the gun for the triggers, I went ahead and cut down the forearm along the ramrod channel to the proper depth and the wood in the wrist area. The photo on the left was before and the one on the right was cut down

Now I can fit the triggers into position.


In order to better define the wrist area, I cut down the butt stock further.

2005-08-03 001.JPG (252462 bytes)Now I ready to drill a hole in the bottom of the wrist to test the inletted lock for any interference. Once I  located the sear on the lock, I traced a line onto the lock plate side of the stock. Next I drew lines over to a center line down the wrist. 


2005-08-03 002.JPG (129989 bytes)Then a 1/8" hole is drilled along the center line and where the sear line cross each other.  Once drilled; now you are ready to test fire the lock. I use a piece of hard wood as a fake flint in the hammer cock. I lower the frizzen. Then I poke a 3/32" metal punch thru the hole. You should be touching the sear. Press upon the sear and the lock will fire.



Here is a movie to illustrate this procedure. (Warning it is a big file = 2.89MB) MOVIE

Next I aligned the trigger plate without all the guts onto the stock along with the rough trigger guard. Note I had already cut off the tail of the trigger plate to fall short of the step in the butt of the rifle.


Since I had shortened the tail, I decided not to mount the rear tail to the stock2005-08-03 007.JPG (234160 bytes) with a screw, but would rather have a short dovetail on the end of the trigger plate so the tail locks itself into the stock. To make this, I wanted to accent it by adding a small piece of brass to the end of the trigger plate. The brass was silver soldered on and then shaped into a dovetail.

The lock plate was inlet into the stock and a reverse dove tail was chiseled into the stock.2005-08-03 011.JPG (255667 bytes)


When the plate is laid down into the inletted recess, it will blend into the stock.

To start inletting the trigger plate with components, I laid the plate in the stock and made a mark where the bolt location was for the leaf spring in the set triggers. Bolt Spring Location.jpg (107911 bytes)

Then I removed the plate and laid the spring into the recess to trace oTrigger Plate Recess with Spring.jpg (106814 bytes)ut it's approximate location. Also removed enough wood for the bolt head to recess into the stock, too.  





Once this was done and the plate laid flush, I reassembled the trigger plate and then inlet the rest of the trigger plate assembly into the recess. Once the assembly was flush, I used a clamp to hold the front end of the trigger plate and tested the triggers. They worked fine.  

Now I was ready for the tang bolt, to "Button It Up".  The location for the tang bolt was to be centered in the barrel tang and then a hole was to be Tang Bolt Alignment.jpg (162022 bytes)drilled thru the tang of the barrel and into the lower trigger plate. IMPORTANT! The hole must be perpendicular to the surface of the tang. Since this was a .64 caliber rifle, I drilled and tapped the hole to receive a 10 X 32 tang bolt. 

V Notch to Depth of Lock.jpg (119985 bytes)

With the bolt hole drilled and tapped, the next thing was to lower the wood surface around the lock to the correct depth. Generally I use my knife and cut a "V" notch or trench along the side of the lock. When done, the edge of the knife will align eventually to the edge of the lock to the depth I want.  I remove the lock and then with cabinet files, I take the wood down until I can no longer see the "V" notch I trenched around the lock. Use a square periodically to check and make sure the surface is still square to the bottom or top of the stock and barrel. 

Here is how it turned out. Lock Panel Exposed.jpg (88319 bytes)Note, I drew a line around the perimeter of the lock. This is the line I will remove the wood in order to raise the lock panel from Lock Panel Raised.jpg (91276 bytes)the stock and blend it into the stock. Using a 5/16" wide "U" carving tool, I cut the wood away from the line. I is important to note, do not cut straight down, but rather carve away at a slight slope away from the line. You want the raised portion to appear to fade into the stock and not have a sharp edge. 


Here is a movie with the lock; triggers and tang bolt in place. In the movie I demonstrate the operation of the set trigger and the front trigger separately.

Next I proceeded to the Side Plate Panel section:
