Rough Shaping a Stock Blank

Anyone that has shaped a chunk of wood into a finished stock by hand  knows it is lots of work, especially in the beginning.  So, there was a question on a method I started using on the last gun I did, and a second that I am currently working on.  There are several way to rough shape a stock blank so I'm not going to say this is the best, but just one of them. But as we get older it's nice to find ways to do some of this work that is easier on the arms and body.   

So I thought it may be helpful to anyone thinking about working from a blank and don't know where to start, or maybe just interested in how it's  done, to see some of the process in the early stages.

So starting with a blank as shown in this first picture, I draw the rough shape of the stock on the wood.

I'm not getting into inletting here, that can been seen in other threads by me and others, but the action obviously needs to be attached to the wood as well as the buttplate. Then the final stock layout can be done and rough shaping started.  This second picture shows how much wood needs to be removed just to get to a rough finished dimension. 

I then use bandsaw to remove most of the wood, to a close finished profile, of the top and bottom.  Third photo.  I have left a little more wood on the belly at this point because I wasn't quite sure where the bottom line would end up as it transitions into the buttplate.

In the case of this gun, it's a Stevens 44, so it has cheeks that will protrude from just behind the back width of the action.  This being the widest portion of the wood, at that point, it is marked on the top and bottom from the center line, with a little extra, just for comfort. The same at the back at the buttplate.

Photo 4 and 5 show the top and bottom with the lines drawn.

I've never felt comfortable with my wood working skills to start with a blank and completely shape a stock. So I'm watching your work in awe Bob!
Even with a semi inletted stock set it takes me forever to final fit, and makes me even more nervous if the action I'm fitting it to is a finished action! 
I know I'm going to enjoy this thread!

I like how you do layout lines, Bob.  I do somewhat the same, but you're a lot more precise and thorough!

In preparation for removing the major portions of the wood, which lays behind the grip and then back to the buttplate, I work the grip area down to the rough final width of the the previously mentioned cheeks.  I do this with a heavy rasp, and by hand, just because I feel more comfortable, knowing and seeing this width, once I start remove the bulk of wood from the grip back.

So here is a series of photos of how I do this in order to keep the width very similar from side to side.  You don't want to get lopsided right from the start so I do try and keep things fairly even. 

This first picture shows the line I need to work to on the top side, and of course, there is a match line on the bottom of the stock. There is probable 3/8  inch of wood to remove.  You can see where I just started on the bottom edge (top in the picture).

In this second picture can be seen I have rasp the wood down to the top line at a fairly steep angle.  I did the same to the bottom.

In this third photo I have work the line, using the top and bottom angle cuts, to work the wood, at the back of the action frame down to the same line.  Note that I do not need a pencil line here because the depth is already established at the top and bottom.  I have also started working the top and bottom angles longer, moving toward the center.

In photo 4, I have worked the bottom line to a center point. 

In photo 5, I have worked the top, bottom and front lines to a peak in the center.  As the wood is worked at these different angles, from the original steep angle, and with a light correctly positioned, you can see when the two angle meet keeping the original width lines the same.

In this first photo I am showing the final picture of the rough grip width completed.  By using a good angle of the lighting, it is easy to bring this down to the final flat surface, without cutting past your original layout lines.

Reading this, it might seem like a long process to get a flat surface, just to a couple lines.  I do it this way for a couple reasons.  First is obvious in that it is accurate and gets you to that flat surface.  You could just rasp this off without all the angles, and that's what I would have done in the past.  But, doing it this way I have found it is much easier on the arms. 

As far as time goes, using the picture time stamps, it took 6 total  minutes to do, which included setting up for pictures.  I would guess, actual time, 2-3 minutes, per side, without stopping for the pictures.

This next picture shows the the front of the wood after removing the bulk from each side.  Still looks like lots of wood to come off, and there is.  I have a rough estimate that the peak of each cheek is 3/16 inch wider than the frame width.  So I have left about 1/4 inch for a margin of safety.

This third picture is of the rasp I used to do the previous work on the grip. It's an Auriou number 3 rasp.  It is very course and in tough wood hard to push, but is the chain saw of rasps!  This rasp is what I would use, in the past, to remove the bulk of wood from a blank after the bandsaw.  If you want a workout buy one and go at a chunk of tough wood with it.  Some caution is suggest if using a rasp like this, I alway support the the wood front and back.  Using a tool like this, with the wood not well supported will put lots of stress, especially on the grip area.

The bulk of wood can be removed using any of several different tools.  A few being, the rasp I just mentioned, chisels, drawknife, hatchets, wood planes, I suppose someone has tried a chainsaw and I'm sure there are more I can't think of.

The fourth photo is of the drawknife I have used one a few stocks but I have found it really only useful in more straight grained wood.  Figured wood just gets too hard and hard to work with one of these. 

I've tried wood planes, and some people like using them, but I find they don't remove wood fast enough for me, and are limited as to where they can be used in stocking a gun.

I haven't tried any other method but maybe someone else has, and can add to the list.

This photo shows what I will be using today, and I used on my last gun, the Stevens Favorite I show in a previous thread here in gunsmithing.  It's a flap disc used on a 4 inch grinder.  It worked really well on the Favorite and we will see how it does on this 44.  The favorite did not have a cheek piece, where this gun does, so I will see how well I can shape around it.  On the Favorite I found it would really remove wood fast if I wanted too, but was very controllable for very rough shaping.

I can't take credit for the idea though!  I think Mike Brooks, redrighthand here, mention it on the long rifle forum.  I believe he said it helped him extend his gun building time as a professional builder.

I will show the good, or bad, when I finish today or tomorrow.

This is very interesting Bobw! Not being much of a woodworker I find it educational. A question though, how do you hold the wood as I always find that problematic. Do you use vices and/ or wood clamps to hold it in various positions? As long as the action is attached that could be used to hold it.

Before doing all that hand work slowly taking of small amounts of wood with hand tools - try using a grinding disk.

I just use a metal grinding disk and quickly silhouette out the stock - then do the fine work using the hand tools.

Takes hours off chiseling down a stock.

I found it works much better than power rasps on very hard wood.

Vall, I really prefer working with an unfinished action or one that need lots of filing and polishing in order to clean it up.  This one can’t be beat up at all!

Richard, I use clamps as you will see coming up.  First side is easy, second a little more challenging but not too bad.  The way the disc works it really doesn’t grab or push so it takes little to hold the wood.

As I mentioned before I buy semi inletted stocks, but when I'm working down the excess wood I use long wood clamps with hard polyurethane ends to clamp stocks lengthwise. Then I clamp the wood clamps into my 6" swivel head vise. The vise allows me to swing it any direction, plus turn it 360 degrees to get at stocks from different angles.
I've seen stock maker's vises, but the long clamps and this vise work great for me, and I don't need another vise on my bench.

Vall, the clamps are how I held the wood while grinding outside on a piece of plywood.  I'll show a picture shortly how I hold the gun in the shop while hand shaping.

This going to be fairly picture heavy, but I don't know how else to explain what I am doing.

Photo 1, The stock is clamped to the plywood and the first pass with the grinder is done down to the line.  This first grinding is just to quickly remove wood down to the approximate final stock thickness.  Shaping will take place after this operation is complete.

Photo 2 and 3, The right side is done, too thickness, and fairly straight from front to rear.  The amount of wood left for final shaping can be seen at the buttplate.  The area where the ruler is laying is always the hardest to work down, the grinder makes short work of it.

Photo 4, still working the right side, I make a contour line of this thickness, I call it a light line or high point.  Doesn't need to be perfect at this point but I just need something to work to.

Photo 5, at this point I also marked out the comb lines and will grind to them as I shape the stock.

Unfortunately, the outside picture are not very good with poor definition because it is cloudy today.  As you will see shortly it started snowing fairly heavily, the temperature was around 30, which it very warm for us this time of year.

Photo 1, shows the final lower right side shaping with the grinder.

Photo 2, shows the right side comb line I need to grind to, along with the center line of the stock.

Photo 3, shows the right comb grinding complete, the center line is still seen.

Photo 4, the left side ready to start grinding.

Photo 5, like I tell my friends...it's not always pretty under the hood while it's being worked on!  Looks a bit rough but should work fine and lots of wood is gone....it's snowing.

Photo 1, top of the left side after grinding.

Photo 2 and 3, back in the shop.  It took exactly 30 minutes, by photo time stamps, to grind this stock.  This saves hours of hard work.  A couple better pictures of both side of the stock just after grinding, nothing else has been done at this point.

So, this thread originally started just to show rough grinding a stock, but since there seem to be interest in this rough shaping, I will just continue with everything I got done today on the this stock.   

If some want to to see more after this, I will continue at that time.

Photo 1, just evening up the wood, side to side, so I can start forming the cheeks.  Like I usually say, I do pretty much every thing by eye, so as these cheeks form I will probably be adjusting the length and height above the frame as I go anyway.

Photo 2, Ready to start the cheeks.  First, I layout what I think I want.  Just hand drawing it on.  In this case I started 3/4 inch out from the frame.  Marked the center line and the outside edges.

Photo 3, penciled out now on both sides.  Looks little long but I can alway shorten it up if I feel it's needed.

Photo 4, Starting the rough shaping of the cheek.

Photo 5, looking at it from the bottom you can see it's not a straight line but a tapering profile blending back into the rest of the grip, off the back of the cheek.

Photo 1, Started shaping the front side of the cheek down to the frame.  Metal foil tape with two layers of painters tape on the frame.  First layer gives me an idea where I'm at, before hitting the frame with a rasp.

Photo 2, Shaping the center of the grip around to the top tang.  This also shapes the top of the cheek and gives it the rounded profile, back around to the center of the grip.

Photo 3, I shaped the center of the stock around to the lower tang.  Gives an idea of what it will look like, still not real straight but this is just rough work anyway.  This will be finished with a very fine rasp that cuts much slower than what I have been using so far and leaves a better finish.

Photo 4, view from the bottom again. I won't do anymore on this side for now until the other side is shaped.  But, I can say the front side is not what I like yet.  It's at too steep of an angle, and not curved enough.

Photo 5, This what the stock looked like when I stopped today.  Two hours from the start of grinding to this point.

I don't start anything else on a stock until the full grip it pretty well established.  This is because the rest of the stock needs to flow up into the grip area and it is impossible for me to know how to do this until the grip area is roughed in.
