April 27 – Finishing off the Stock
Ok….so you may remember from a couple of postings ago that I
decided to move on to the process of finishing the stock while I wait for the
drill and tap on the receiver.
The stock has been shaped now to its proper dimensions and
everything seems to “feel” right.
My chief concern was to reduce the shelf (where the barrel meets the
wood) to a nice 1/8 inch from the ¼ inch I started out with. That has been done and the curvature of
the wood around the fore end has a nice symmetrical geometry to it.
Now, the fun part!
I’ve partially removed the recoil pad, this will act as a “holder”
so that I can manipulate the wet wood with the finish on it, and not mar it
with finger prints.
To protect the wood from minor abrasions, but most
importantly human oils, we need to get a protective “shell” on it. A polyurethane coating is nice,
and we will put one on at the end, but we want a deeper penetrating
protection….for that we will use Linseed oil.
So here is what we’re going to do….we will pour a little
linseed oil on the stock and use 600 grit sand paper as the application
medium. We will quite literally
“sand” the oil into the wood. This
does two things…. it obviously will spread the oil about the woods
surface, but more importantly it
will create a sawdust/linseed oil mixture in the process. This paste product will be worked into
the pours of the wood during the application process and harden into the
wood. Essentially we are filling
the imperfections of the wood with itself!
You can see at the bottom of the picture the area of the stock that has not had the oil applied yet, and the color difference between the two.
The other benefit of linseed oil is that it naturally brings
out the color of the walnut (especially the marbling) without having to “color”
it with stain. What you see is
what you get. A beautiful specimen
of American Walnut!
Now, we will need to let it sit for a while and dry.
I will end up doing this exercise seven
or eight times before it is complete, then I will do it again, this time with a
polyurethane finish. Once that is
completed we can move on the checkering phase!
