Over the Comb Tang

[Ken Guy]

Don't know if anyone is interested or not but I thought I would post in case. The information has been posted in bits and pieces in several threads and I thought it might be helpful if it was mostly in one thread.

I started an "Over the Comb" tang today and took pictures as I went.  I'm sure there are lots of ways to accomplish the task.  If your method differs from mine, feel free to post.  

The tang is just a long straight piece of metal at this point. Measure where you want the wrist screw to go and drill that hole.  I glue or solder the screw in place to help when shaping the tang.


This is the point where you are going to spend some serious quality time with your bench grinder and best files. Getting one of these shaped is a lot of work.


You'll want to bevel the screw boss or you will get a gap at the top of the screw boss.


Now the first part that makes me nervous. Making the bend for the wrist to the comb. Too short and your out of the wood. Too far back and you are in for some real work. The problem for me is once you heat the tang red hot any marks you may have made are gone.  I carefully measure where I want the bend and then bolt a little piece of copper to the tang that will indicate the exact spot where I want the bend. I'm sure there are other ways but this works for me.


Heat the tang red hot with a small torch and bend away.


Others may do this different but I always leave the tang straight till I get the inlet started.  


Once you get going down you can make the bends where you need to. Bending a long tang that varies in thickness and has a hole in it presents some special problems requiring finesse bending, not brute bends.  


After getting the tang bent to shape the first thing you will run into is the tang hitting the nose of the comb. Second part that really makes me nervous. Make dang sure it is straight an centered on the comb.  


Keep them chisels sharp and work her down. A's much as you may want to have the nicest tightest inlet you have ever done, this is not the time. You do not want it fitting so tight you have problems getting the barrel in and out. You should be able to tap the butt with the rifle upside down and the barrel come out. If you pull it up and out by the muzzle you will bend the tang every time.  


I leave the tail sticking up like this for now. Take the breech out of the barrel and proceed with building.  I guess you could inlet it across the top of the comb now but I like to get the buttplate inlet.   The angle of the comb may change when you inlet the buttplate. OR at least it does for me sometimes.  
Cheers,
Ken

How long are you going to make the tang???  (How far down the comb is it going to extend?)

I have a Southern Mountain fantasy gun in the works, but I was just planning on the tang running about an inch down the comb.

[Ken Guy]

Lloyd,
The tang will extend all the way down the comb and tuck under the buttplate comb.  I think the most common over the comb tang I have seen on TN rifles does only extend an inch or two down the comb but there are plenty that go all the way to the buttplate comb.  Some tuck under, some have a screw on top and you'll even see some that have a lug underneath and are pinned like a trigger guard would be.

Excellent, excellent pictorial, Ken.  Clear photos, steps taken in a logical order, verbage plain enough that an escaped mental patient up in Corn Patch can understand. Glad you are sharing with the craft.  Can't wait to see the next instalment.  Cheers, Bookie

Ken,

How's it going buddy?  Thanks for posting that with the great pics.  Makes me wanna throw up.  Why?  Cause I love the southern rifles with long tangs, but know what you mean when you refer to a part of the inletting that "makes you nervous".  I about lost it inletting the lollypop tang on my rifle.  The "gap will appear here" drawing looks all too familiar.  I'm chickening out on my next one and claiming to love SW Va rifles so I can do a shorter tang.  Good thing I'm an Elisha Bull fan, his tangs stop at the top of the comb haha!  Forget that all the way to the butt plate stuff.  I'll leave that to you and Keith.  Just kidding, I guess I'll try one someday when I am ready.  Maybe I'll still have my eyesight.  I admire your work and knowledge of southern rifles.  Keep it up.  By the way, is 10 weeks too long on a set of southern triggers?  I'm still tweaking mine.

[Nate McKenzie]

Great tutorial, Ken. Hope you'll show it going the rest of the way. Was there a certain area of Tenn. or elsewhere where this style was used?

Ken,
Great work.  This job is at best tedious to do, but the results are well worth it.  Did you you weld an extension to a breech plug or make your own plug with the super long tang?  Look forward to seeing the remaining of the work.  Everyone needs to do at least one to appreciate the delicate work you have done.

Thanks guys and glad to see there is interest in these long tangs.  As Roger pointed out they are tedious at best.  Hard to imagine some gun builder putting them on every gun they built.  I'm continuously wondering what the true purpose of the long tang might be.    

Nate,
It's mainly rifles from upper E. TN that are known for having long tangs that extend up and over the nose of the comb.  

Greg,  A tang going all the way to the buttplate is only a wee bit more work than just over the nose of the comb.  The two bends are the worrysome parts.  Keith has it down to a fine science.  
Them triggers is some work.  The first set is the worst and then they get easier and easier.  

Roger,
This is a barrel Bookie and I rifled a year or so back and it was never threaded for a breech plug.  I sent the barrel off to have the breech threaded and had a breechplug with long tang extention made at the same time.  I'm pretty sure it was Bobby Hoyt but it could have been Ed Rayl?

Cheers,
Ken

I do mine a lil differently than Ken does, but results are the same.  Inlet the barrel & tang & 1 tang screw to lockplate in, get the barrel pinned in, lock in, trigger in, buttplate & toeplate on. Then I make the extension for the tang & take the tang off the barrel.
The reason I take the tang off is because it is very easy to keep bending the extension when you have 44-46-48" of barrel on the other end, and not want to bend it, and believe me that sucker catches Everything.......    Thus I take it off & deal with 12-16" of metal rather than 60" of metal at a time.  
Take the tang & extension to the welder & weld them together & make sure they have a lil extra support under the joint & taper if toward going out the extension.
Take the piece back, clean up the welds to the shape I want, heat it & anneal the weld,  drill pilot hole into boss for screw, bend the extension up behind the boss where I want it, inlet that part of the extension.  Then I bend the over-the-comb part & inlet it.
Put the buttplate up over the extension & mark where it will butt to it.  Take the tang out of the inlet & cut it off, saving 1" of the part I cut off. Put the whole tang back in & check measurement again at buttplate, take back out & grind then file to ? .025 of where I need the end to be. Take the 1" piece I saved off the extension & out 1/2" of it under the end of the extension & silver-solder it on the end. This is the lip that will go under the buttplate to hold the rear of the extension down & in place.
File clean it up & back to the stock for final fitting, buttplate on & file fit til I have about .010 clearance between the buttplate & the extension, fit buttplate back on & insure everything goes where it is supposed to.
Take it out & put the tang back on the barrel & back in the rifle, clamp boss & on drill press with drill pilot, drill boss hole & countersink & then tap hole & install screw & cut off excess.
Now I do the final filing down on the extension & final shaping, etc.

It is Imperative that you refrain from bending the tang upon installation & removal every time. If you bend the extension & straighten it, the metal grows in Length & now it won't fit, as the boss has moved....  This means shrinking the extension in length or cutting it off & reweld it, or making a new one, or having sloppy inlets, etc.  Thus it is time consuming & frustrating, and if you are not a patient person, this may not be something you want to start.  Once you make that initial cut down the comb, you are committed......  

As for it being a useful item on a rifle, I can find no use for it other than it protect the top of the comb & point of the comb a tad, but not a protection from anything major. I feel it adds no strength to it as it is too small a piece to give any noticeable strength because it is mild steel & small/thin.   However it is an appealing feature that I like, thus why I do some of them....

[Ken Guy]

Once you make that initial cut down the comb, you are committed......  

Boy, that's true!  There's no second chances or wiggle room once you get going with it you are committed.  

Thanks for sharing your way of doing them.  Your results look great and prove there is more than one way to get to the same end point.

KEN, IS THAT A PRE-CARVED STOCK AND IF SO WHICH ONE?

[Ken Guy]

Mike,
Yes it is a precarve but it is precarved from a pattern I made and sent to a stock maker, not one that is out on the market.  This is the first rifle I've built from it so the jury is still out on how it will turn out.

  Great tutorial, look forward to seeing the next installment. Question: How close to finish shape are the wrist and comb when you start?

PS: I like your bending jig.TC
  
 

[Ken Guy]

Tim,
On this pattern and for this barrel size (13/16)  it is very close to the right size in the wrist area.  I left a lot of wood on the butt and around the lock panels.  Maybe too much on the butt.  Those are the areas that need tweeking on the pattern.

Ken and Keith,

This gives me even more appreciation for what you boys do! I have trouble just sharpening a pencil )

Ken,

Is that going to be a Soddy rifle? Hard for me to tell from the pictures?

Thanks,

James
