Greg is absolutely right. The wood looks like a single piece of beautiful walnut with a Hepburn action sitting on it near the middle. 
I have a favorite rifle that Bob has built, but it may soon fall into second place. However, that won't be any shameful change, they are all stunning.  Smiley

It looks like the tree grew around the rifle.

Thanks guys!

Now I'm going to backup and show the layout and shaping of that forearm.

This will cover the next 5-6 posts that are picture heavy, so sorry in advance.  This should end up being more detailed than what I usually do.

I talked earlier about not being comfortable with my original profile drawing.  These first two pictures show the change I made.   

The first picture is the original drawing copy, shown as I was transferring it to the wood, I didn't get a picture of the actual drawing before changing it.  I also flip the photo so the forearm is orientated the same as the second picture so it's easier to compare the two.

The second is the actual drawing of the the new profile.  This version is much slimmer and flows much nicer up into the schnabel.  It isn't so pot bellied.

Photo 3.  After the drawing was transferred to the wood I needed to be sure the layout lined up and was going to flow properly off the action frame.  So I rasp the wood down just in  front of the action until I knew the frame lined up with my layout, and sure I was good to continue.   

Photo 4.  At this point I went ahead and band sawed the the excess from the blank of walnut.  I still leave a slight margin for any errors or adjustments that I want too make.

Photo 5.  Now it was just a matter of rasping off wood until I have a nice smooth flow all the way forward and around the schnabel.  This needs to be very close to the final shape so that as the modeling starts taking shape I'm not constantly make changes to this profile.

More to come.
Bob

Continuing with the forearm.

Photo 1.  This shows how close I rasp the wood down to the action frame, showing what I mean about it being close to the final profile.

Photo 2.  I've talked lots about guide or layout lines, and here's more about them.  There maybe people that can shape a stock without lines, but I'm not one of them.  In this picture I'm showing the layout lines for the full width of the forearm.  These may be narrower, against the barrel, than many may realize.  At the rear, in front of the frame, it's 3/32 or .093 wide agains the barrel.  At the front .070.  I simply use a drill bit to measure at each of these points.  The sides will be cut down, to these lines, square to the top barrel flat.  Visually, from the top, these flats will get narrower a I shape the sides and radius up from the side layout line.

Photo 3.  The layout line used for the the side shaping.  The wood above and below this line will be removed and modeled into the top line, along the barrel, and the lower center line that I will show next.  Although I said the profile needed to be very close to the final shape, that's not true of this line.  I will move this line, as I see the need, for the look I want to the modeling.  This also shows the thumb nail extension off the of the frame which needs to be shaped and properly flow into the forearm.

Photo 4.  More on lines!  This bottom center line keeps all shaping centered to the frame.  I have also added the schnabel side line for shaping later.

Photo 5.  Here I am finally starting to shape the forearm.  I always start at the bottom at a shallow angle to the flat bottom, cutting up close but not to the pencil line.  As can be seen I have worked both sides down the same amount....give or take a little.  By staying short of the center line gives me the ability to radius, to the line later, as I progress in the shaping, without ending up with a flat spot in this area.  I don't really work the schnabel much at this point.

Photo 1.  After cutting the bottom angle, on each side up close to the line, I move to the sides.  This picture shows starting the wood removal on one side.  Again, this is cut at a low angle up to the line.

Photo 2.  Continuing the rasping up to the line.

Photo 3.  I then turn the gun so I can access the corner where the side and bottom line connect.  This picture shows this edge.

Photo 4. At this point, some stockers I know, cut narrow facet to form the rounding of the wood between the bottom center line and the side center line.  I use this same method at times but not here.  I just form the rounding as I work the wood down.  Here I have just started the contouring at the front of the forearm.

Photo 5. And then a close up of this rounding.  As can be seen this is rough work with a course rasp and I'm still not working to the line, allowing the the use of finer tools later to get a better finish to the wood.

Photo 1.  Continuing the rounding of the wood.  I'm still not working the schnabel.  At this point I'm using clamps to hold the forearm in place.  As I get closer to the final size I will get the screw in place to hold the forearm.  Then I can work the whole forearm, including the schnabel much easier.  I make the screw and brass insert and I need the wood fairly close to the finished size in order to get them correctly sized to the forearm. I'm also not working the thumb nail extension coming off the frame.  This takes much finer tools to shape, so I will work it later.

Photo 2 and 3. It's hard to show this rounding but these are an attempt.

Photo 4.  Here I have started the rounding above the side line.  This is tough to do with the barrel in place but I get it started and then remove the forearm wood and finish.  This also continues the narrowing of the wood showing, from above, against the barrel.  And while doing this I do bump the barrel some, but since I have not draw filed the top flats, or polished any, these will cleanup when I do.  

Photo 5.  This is bottom view after rough shaping both sides.  All the layout lines are still in place.
Bob

It is going to be a darn nice rifle, Bob.

Question, how long is the forearm and the barrel?  I like your proportions!

I for one look forward to you shaping those thumbnail portions front of the action. Selfishly, as I have to do one this winter myself.

13 1/2 length of pull.
11 1/4 forearm length .
30 inch barrel, 29 showing.
Action frame showing, about 3 1/2 inches long.

I don’t think anyone has ever commented on the proportions of my guns.  Since you brought it up, this is not by accident.

I use my version of the old golden mean ratio, which is simply dividing 1 by 5.  The best ratio is 3/5 to one or 60%.

So using the numbers above.
29  barrel showing
3.5 action
12.5  pull less an inch because the trigger pull in longer than the stock wood.
———-
45 is the approximate total length of this gun.

Then.
12.5 stock length
3.5 action
11.25 forearm
————-
27.25 total length to the forearm tip.

27.25/45= a little over 60% 
The length of the gun, to the end of the forearm, compared to the total length is 60%

I generally will allow this number to be between 60 and 63%.  This number is known and calculated in before I ever start building.

I know…some will think I’m crazy, but it’s just my OCD! Cheesy Cheesy
Bob

Being reluctant to keep showing more of this initial shaping, I still want to show one more picture that's more from the side.  A little better view of how it rolls away from the pencil line, both toward the top and around the bottom.  From here I will start working to the front and back shaping the schnabel and the thumb nail at the back.

I think these two picture are self explanatory.  Rough shaping the schnabel.  I'l show the refining of this later.

As a break from the humdrum of shaping this forearm.... here's a preview to the natural color of this wood.

Holy moly. Look at that figure right at the schnabel! You planned that perfectly.
