Hand-Forged Trigger:
I took a piece of 3/32" steel bar and
peened it with my hammer to make the trigger. 
Then I laid the trigger material next to the rifle and drew the basic shape of the trigger. (Note: I did not keep the original design).
I
wanted to hinge the trigger within 3/8" of the 
sear
arm. This makes for an easier pull. Using a hacksaw, I cut out the basic
shape of the trigger and put it next to the rifle again.
I drew lines across the bottom of the stock to indicate the width of the trigger. Then drew a center line down the belly of the stock. Between the two lines, I cut a "V" groove and drilled a series of 3/32" holes to the depth of the trigger into the stock. Using my chisels and knives, I removed the wood.
Next I pinned the trigger into the stock with a 1/16" pin. Note the trigger is too long right now, but I will shorten it later.
With this done, I now need a trigger plate.
Since
this gun is unique, I had to make special trigger plate. Thought I would have a
feather on a ball. I drew and cut it out of 3/32"
thick brass. Here you can see the piece of steel I plan to solder to the
back side of the plate after it is inletted. This will strengthen the trigger
plate for the tang bolt later.
Here the plate is cut out and inletted into
the stock. 
Now I soldered the steel to the backside of the plate. 
With the steel soldered onto the plate, the plate was re-inlet into the stock again.
You
can see I have shortened the trigger at this point, too.
Now I want to install the tang bolt. First I
drill a
3/32" hole dead center in the trigger plate I want the tang bolt to pass
thru. This will aid in positioning the rifle for drilling the tang
hole.
I used my tang bolt drilling jig. 
For more information on using this, see the Tips & Aids section under Tang
Bolt Jig.
Once the tang bolt (8 X 32) was drilled, the trigger plate was removed and a passage hole drilled thru the tang and the stock. Then the plate was reinstalled and tapped.
Due to the narrowness of the barrel tang, I
had to mill the width of the tang bolt head to fit the tang. 
The
excess length of the both extending thru the trigger plate was cut off as seen
here.
With the trigger and tang bolt installed, next will be the butt plate.
