Pouring The Nose Cap: (Click
photos for larger view)
The
nose cap will be 1/8" down from the muzzle of the barrel. The length of the
cap approximately 1-5/16" long. It will be a simple nose cap, since these
were solid nose caps for this time period.
Once the end of the nose cap was identified, a
mark was made 1/4" farther back. This will be where the end of the stock
will be cut flush.
Using
a small toothed saw, I measured the depth of 3/32" from
the edge and made a mark. Then drew a line parallel with the saw toothed edge.
This served as a depth gauge for the cuts made into the stock. I made a series
of parallel cuts about 1/8" apart, then used a chisel to remove the excess
wood. The depth of the cuts made it easy to maintain the proper the depth.
With the excess wood removed, I then cut off
the barrel side panels on either side of the nose cap. This will allow metal to
flow and fill this area fully when the cap is poured.
Next I used a 3/32" drill bill and
drilled a series of holes into the nose cap area. Then I used a slightly larger
drill bit to bevel the hole on either end. This will
aid the flow of the metal and form rivets on the other side to lock the nose cap
to the stock.
Now I put the ramrod into the stock and used
masking tape to cover all exposed holes in the stock. This was done to prevent
any metal from accidentally being poured into parts of the gun it is not
intended to go into.
Using index stock paper or thin cardboard,
wrap the nose cap area. Before fully taping the mold into place, check for a
uniform gap between the wood and the a
cardboard. If the wood is not evenly gapped, remove the cardboard and remove the
excess wood.
Once you are satisfied, wrap the area with
tape several times and make sure the wooden plug for the barrel is securely into
the end of the barrel.
Heat the pewter up until the metal flows
smoothly. Do not over heat as you do not want to scorch the wood when you pour
the metal into the casting you made. When you pour the molten metal into the
casting, I use a rubber mallet and repeatedly tap the barrel. This
vibration assists the metal flowing thru out the casting and prevents any
air bubbles or gaps in the casting.
Here is what it looks like after the metal has
cooled after a couple minutes and the casting cardboard is removed. Note, here I
used a ruler and continued the top of the stock barrel channel, then cut off the
excess metal already.
Once the excess metal has been removed from
the sides, remove the barrel from the stock. Now you can see the inside of the
nose cap area. Note, the rivets formed on the inside of the stock. You must
also, remove the excess metal from the end of the stock, too. I used a hacksaw
to do this.
With the barrel still out of the stock, I put
the stock into the shop vise and then I rounded the sides and the end of the
nose cap using my bastard files to eventually my finer files. You will notice
you will have to clean the files often a metal particles will build up in the
files. you will know this when you start seeing scratches in the surface you are
filing. Use a metal scribe or your knife to flick this metal out of the files
along with using your file brush.
