BEDDING THE STOCK AT THE BREECH:
Joe came into the shop the other day and said
his breech area seems to be a little loose. To remedy this, the best solution
was to bed the breech area with Acra-Glass epoxy. This will fill any voids
making the breech more solid and stronger.
To start with the barrel and breech were
removed from the stock.
Now I take masking tape and cover any exposed
holes in the stock including the tang bolt and places you do not want the epoxy
to get into.
Next
step is to epoxy the breech onto the hooked end of the barrel. This makes for a
solid piece of metal to be clamped back into the stock when we are ready for
that step later. Once this done, the tang hole on the bottom of the tang
is taped over and the flash hole in the barrel.
While the epoxy is setting on the barrel and
breech tang, bring out the Acra-Glass. I use the Green box. This makes a good
hard epoxy when it has finally set.
Open
up the bottle of release agent. Using a special applicator (cotton swab) I
painted the stock area surrounding the breech tang and barrel. This will make it
easier to remove any excess epoxy later.
By
the time I've finished this, the epoxy on the barrel has set. Using my knife I
cut off excess epoxy so I can have nice tight fit of the barrel to the
Acra-Glass in the breech area. Now I an paint release agent onto the
breech tang and barrel. I apply at least two coats to everything and allow
it to fully dry between coats.
After the second coats dry, I then use a
toothpick and draw equal amounts of resin and hardener onto a piece of paper.
(Use a different tooth pick for each one; do not want to contaminate each
other.) Then I mixed the two compounds together by folding one into the other.
Do not stir heavily, so as not to stir in any bubbles into the mixture. After a
couple minutes, you then cut the end of the brown color tube and put just a pin
head amount of color
into your mixture. (A little goes a long ways.) Stir a little more till you have
a good color thru out the mixture.
Using the toothpick, pick up a small amount of
epoxy and put into the breech area of the stock.
Keep
applying the epoxy until the area is full.
Now take the epoxied barrel and place it into
the stock. To help pull the barrel into the stock, use a clamp to draw it
down. At this point using an oily rag, wipe off the excess epoxy off the
tang area and then apply a second clamp onto the tang.
Put the barrel pins into the barrel tenons down the length of the stock.
Now the barrel will sit for 12-14 hours in the
clamps.
After this time has elapsed, remove the
clamps. Clean off any epoxy along the edges which may prevent the barrel from
coming out. This is generally between the lock cavity and the top of the breech
along the side of the barrel. Now take the rifle upside down and gently
tap the comb of the stock's butt onto the work bench whilst holding the barrel.
Do this carefully and gently the barrel will
come loose.
With the barrel out, you can not remove the
tape you applied over
the tang hole in the wrist and the other pieces of tape you put onto the stock.
In the process you will find a very thin blue film on the epoxy. Remove this
material because it is the release agent you painted previously onto the barrel
and the breech tang.
Now the stock should look like this at this
point.
Looking at the area where the breech hook
interfaces with the
stock, you will see this area is not solid and more release agent film here
too.
Before proceeding you need to remove the extra
epoxy in the hook breech cavity. This area is needed
in order to be able to pivot the hook breeched barrel out of the stock later.
Using my propane torch, I gently heat the
barrel tang and pull the breech tang from the barrel. Once these are separated,
they are both cleaned up by removing any remaining epoxy.\
Put the breech plug back into the stock and
secure with the tang bolt. Next install the barrel into the breech and insert
all the barrel pins.
Let the barrel set at least 36 hours before
taking the gun out shooting. This way you know the epoxy has fully
set.
Job is now COMPLETE!!
