Bobw, thank you for pointing out the subtleties in the shaping of the stocks you make.

When I do "stockmaking," (I use the term with my usual devil-may-care abandon) I generally get the wood to a point where the shaping is close to what seems to me to be optimal, but "off" in a way I can't identify.  I'm generally afraid to go any further, because I can't exactly see where the problem is, and think that anything I might do would take off wood that I can't afford to lose.

At that point, I generally say to myself, "Well, from six feet away, it looks like a stock; it's functional at least, and since I've been at this for months, I'd sure like to shoot the rifle before I'm too old and decrepit to do so."  So I smooth it down and apply the finish.

Your tutorials are great, and anything you can bring up about developing that "eye" for proper proportions is golden.  My Howe gunsmithing book says that proper stock shaping is simply a matter of going over and over it, in smaller and subtler increments, using one's eyes, one's experience, and one's sense of proportions to achieve the final result.  Alvin Linden, on the other hand, thought stock shaping was a matter of working down to lines and precision measurements.  I remember him writing something like, "Looks like we're almost down to that final shape and we haven't used any of this 'trained eyeball' stuff yet to do so!"

You might think of combining these articles into a book; "The Single-Shot Gunsmith" or some such.  I'd buy a copy for sure.


Other than muzzleloaders I have never read up on stock making, so these books are not familiar to me.  I do use measurements for placing lines and for thing like the grip width, but other than that I use the method you mention by Howe.  I usually end up with four passes in shaping.  The first is really course shaping, then rasping/shaping to a close final size, maybe within 1/32 inch.  Then really look it over and make any changes to the shape or modeling.  After any changes then I take it to the final size and shape with fine rasps. After the rasp it's sanding which I can do some fine shaping with.  

I've had really good stock makers tell me 1/16 inch can be the difference between an "ok" stock and a great one.  I actually believe it's even less than that.  

I was also told a long time ago, get the wood down to were you are done and then take more off!
Bob

Thanks Dave.

Bob,

You should be commended for your ability to stock a Hepburn with style. The design of the action, with the grip area being so low in relation to the centerline of the bore, really complicates the creation of a classic style of stock.  Honestly, the original Hepburn stock almost makes me cringe, as the lines  break all the rules of what a classic stock should look like (although the stock might be very functional).

It looks like part of your magic involves a tall butt plate to set up a classic toe line, and a functional comb line.  My guess is that planning this all out took a lot more effort than stocking something like a Winchester 1885 or Remington rolling block.

Well done!


AJ,
Yes, the taller buttplate really helped.  My first drawing was with a shorter plate.  I think I redrew the stock 4 times before settling on this one.

Bob

Back to the gun.  I got going on the forearm wood the last couple days.

I didn't take any pictures of fitting the wood to the barrel.  The barrel has some taper, but not much, so I mounted it in my mill and milled out the octagon shape, to the barrel size at the front of the octagon section of the barrel.  The octagon section is only under the forearm wood.  I then hand fitted it to the octagon barrel section by sliding it back and removing wood until it contacted the action frame by using inletting black on the barrel.

The first picture is just showing the top of the forearm when installed over the barrel.  When completely installed and finished the forearm will be much lower on the barrel side flat, most of the flat will show above the wood.  This is part of what I talked about earlier, on everything narrowing or getting smaller, as you move forward on the rifle. 

The second shows the wood getting fitted up to the frame and the tenon section that fits into the front of the frame.  That tenon really stabilizes the forearm but I'm not sure how it will effect the accuracy of the gun.  Normally I leave a small amount of space between the forearm wood and the metal.

This third pictures shows the frame imprint from the inletting black as the wood is fitted.  The cycle is black the steel, install and give the wood a couple taps, remove the black from the face with what ever tool works.  Repeat until it fits. 

So fitting the trigger frame tongue, it sticks out the front of the frame, was a question as to how to do it.  It ended up being very easy.  I held the forearm forward, not pushed clear into, or against,  the frame.  I installed just the two rear screws in the trigger frame, attaching it to the action frame, and rotated the the frame down onto the forearm wood, with inlet black on it. I removed wood under the tongue until it was down and I could install the front screw.  Once the front screw was in place I just started inletting the forearm wood "back" on the barrel, until it was tight to the action frame.  Usually, if you rotate a part into wood while fitting, you end up with a gap at the front between the metal and wood.  Inletting the trigger frame tongue short in the wood, and then finishing by moving the wood back into the tongue until contact with the action frame, this gap does not happen.

Picture 4 and 5 are showing this process.  In 5 you can see the tongue is tight to the wood but, there is still a slight gap along the action frame.

Hope that last post was understandable! Cheesy   

It was hard to explain!

Continuing with the forearm fit to the frames.

This first pictures shows the wood blackened by the inletting black (arrows).  The wood, above the arrow points, will be removed later. 

The second shows the black removed.  In order to progress quickly while removing this black, I chop it out pretty quick until I get down close to the final fit and then slow down to just scraping the black off, along with a small amount of wood.

The third picture shows the trigger frame is actually touching all the way around on the top edge in the picture.

And lastly the final fit.  If a part is fitted like I have explained it should look good when the final shaping is completed.
Although I'm not saying this is the only way to inlet parts.  There are other ways, but being self taught, this is how I have always done it.

Thanks Vall.

Continuing with the forearm.

After getting the wood fitted to the barrel and frame, it's time to remove the extra wood from the sides.  This first picture shows the sides already narrowed, sorry no pictures from before trimming the sides.  As a guide, I mark the top of each side with a pencil line.  I cut the side off, on the bandsaw, to just outside the line and finish with a rasp to the line.  As discussed earlier, this is just the starting point and more wood will be removed.  The barrel has a taper, but the wood will taper slightly more than the barrel, narrowing at the front more than the rear. 

The second picture is from the side before cleaning up with a rasp.  As I rasp the wood off each side I get the side straight, front to rear, and square to the top barrel flat.

Yesterday I mentioned that the wood will be lowered, showing more of the barrel side flat.  In this third picture, I am showing the line I will trim to, at the top of the forearm.

The fourth picture is showing the side trimmed to the line.  Although it's the opposite side from picture 3.

Picture 5. To trim the side down as shown in pictures 3 and 4, I start this removal using a fine rasp and working from the center of the forearm out, cutting at an angle down to the line. Arrow 1.  By doing the work in this direction, center out, any chipping ends up on the outside which will be shaped later, removing any damage.  Once the angle is cut to the line, I flatten out the rasp and then remove most of this angle. Arrow 2.  I then repeat this on the other side.  Then once the second side is complete, I then work straight across both sides, finishing the tops, making them flat and somewhat straight.  I use a very fine rasp so I don't damage the inside edge of the barrel inlet.

I will, more than likely, lower this top edge more later, but for now this will work.

This first picture is showing the front of the forearm, barrel inlet shape and the sides.

This second picture isn't a very good one, but does show the wood height against the barrel side flat.

Photo 3, this shows the fit of the wood to the barrel, I got a bit wide at the rear, just in front of the action frame, but it will be fine when done.  This picture also shows the taper to the top of the forearm wood, although a little exaggerated.  The reason for this is because of what I am showing at the arrow.  The side of the forearm has a cheek coming off the action frame, just like the the stock has.  The arrow is pointing to the place where the cheek is at its maximum width.  In front and behind this point the forearm wood will narrow up.

Photo 4, This is the transfer copy of the forearm profile from my drawing.  The actual copy is against the wood.  I then run a pencil over the lines on this side of the paper and the graphite transfers to the wood.  After taking this picture I realized my copy was too short for the forearm wood length I actually ended up with.  I simply moved the paper forward so the front was at the point I liked on the barrel.   

Photo 5,  Once I know the transfer happened, I remove the transfer paper, go back over and darken the lines on the wood.  The picture shows the profile I will shape the wood too.

Today while doing this transfer I decided there is something that makes me uncomfortable with this profile....I just haven't decided what it is yet!  There's a good chance I won't cut the profile out until I figure out what it is.

No apologies necessary. We all have our own ways of fitting wood. If it works for you then go for it. I like the profile you chose. Going to look great.

Will you simply shape a schnabel tip on the wood? Or will it end up with a horn, ebony, or steel tip eventually?

At this point just wood.  This forearm is a very close representation of the gun on page 255 of Tom’s Hepburn book.  I like this style tip but it is somewhat different than I have done in the past and is also shaped different than what Stevens did.  In my opinion the Stevens seem to be both shorter and taller than this schnabel.

I looked hard at horn originally and I have plenty if I were to change.  If I had gone that way, the tip would be shaped more like an extension of the rear of the forearm, basically rounded off.  I also thought about a horn tip and shaping it like what I am presently doing with wood.  But decided that might look strange combining the schnabel shape with horn.

Although, here’s a couple picture of an ebony tip I did on a modern rifle stock.  It has a schnabel similar to the one I have planned, just shorter.  Pictures aren’t real good but it’s the best I have.

Maybe I should do something really different and copy what I did on this modern gun. Smiley

Bob,

Since your mentioned Stevens, I’ll share that my first thought when looking at your forearm design was that it looked like a Stevens, but without the slight belly forward of the receiver.

I built a forearm for my Ballard #10 Scheutzen Junior that came without a forearm. I tried to copy some horn tips I have on original Ballard rifles and I like the small schnabel they have on their forearm tips.

I have a whole bunch of pictures of the layout and shaping of the forearm that I will show in a few days.  But first I decided to show where things are as of stopping today.  It's probably 90% shaped.

These give a pretty good Idea of what it will be when done.  I did add the upside down view because I think it shows the profile better than the others.

Besides the fantastic shaping, I really like the grain flow from schnable to the butt plate.  Thanks for sharing.
