Ballard stock adaptation/inletting/fitting

This is an incomplete project, but I have been promising a few people I would post it, so here it is in it's incomplete state.

I have a number of semi-shaped Ballard buttstocks.  I'm not a traditionalist, and my thoughts of what makes a usable rifle differ a bit from the original Marlin Ballard stock layout.  Unfortunately, the blanks were shaped to more or less original configuration.  Fortunately, for me to be able to modify them, they weren't drilled for the through bolt.   Or unfortunately, as that's a bit difficult to do, but perfectly achievable with a bit of effort.

I'll start by illustrating how I want the stock to fit.  My intention is to raise the comb a bit, and make it parallel to the bore.  The original slopes downward at about 15 degrees, more or less parallel to the ballard receiver.  

Here's an original angle stock overlaid on the angle I think it should be:

I want the top of the comb to be parallel to the barrel, use a straight edge to lay it out behind the receiver, to that angle: (this picture is out of sequence, actually after I've drilled the stock and cut the front to the angle to match the receiver).

I mark the through bolt location at the receiver end, and the butt end.  The butt end location drops about 3 inches from the factory ballard location, because of the angle change.  Set up the lathe, with a dead center on one end, and use a series of center drill, short drill, and finally long drill to do the through bolt hole.  This is the easy way to make it come out in the right location at both ends: (You need to Login or Register to view media files and links)

After the small hole is drilled, I use a series of larger drill bits to drill out the tang end, then use a MT2 reamer to do the taper, and then finish inletting to tang shape by hand:

With the tang inlet and through bolt ready to draw the stock onto the tang, I can start laying out the inletting.  I didnt take a picture of it, but I put the stock on, and marked a parallel line on it with the back of the receiver.  There was a large angle difference between the factory angle stock and my layout; I went out to the shop and used the chop saw to recut the front of it to the new angle.  Then, started removing material to get the wrist close to receiver size; then thinned the sides of the stock to be more parallel to the receiver instead of bulging out:

With it down to shape, I need to inlet it.  I tighten the through bolt, tap the butt with a rubber mallet, and that gives me an inlet line to start cutting the shoulder that fits inside the Ballard receiver.  After it's started fitting into the recess, I use inletting black on the receiver, and remove high spots until the inlet is complete:

I also want it to be a bit better shaped cheekpiece, and with a shadow line, so I lay that out with a pencil and cut with chisels to shape, and smooth a bit with a rattail rasp and a flat file:

Here is a picture of how the bottom of the stock aligns with receiver when it is finished:

And the rough fit stock compared to a rough shaped one:

The point of this post is that you don't have to live with pre-shaped stocks, you can modify to fit to accomplish what you want.

Reality is that too few have your skill and experience.  Still, that's a very interesting set of photos with much to be learned from them; so many thanks.

LOL!!!  Yeah, it always looks easy in pictures when someone else is doing it. I know better. My biggest problem is I stop sanding too soon. Don't get rid of all the little scratches. But I keep trying.

Ballards may be weaker,

Great tutorial Dave! I've had to do some of this to realign stocks that were off center, or didn't have enough wood to fit up properly.
Thanks!

Nice work Dave!  Looking at the starting stock I wouldn’t have though you could this.  Going to be nice when you are done.

Nice work Dave!
I made a few scrapers from some O-1 rod and a screwdriver for Ballard tang stock work when I was doing mine..already had a reamer for the tang. Need to get back to that...
Fun stuff!

Do you drill the bolt hole from one end only?  I have heard stories of the long bit wandering off center.

I have a HW stock to drill

Thanks

Great work SSDAVE!


IDJEFFP, I’ve mentioned before that I make scrappers out of spade drills, but I don’t think I’ve ever posted pictures of them, so here is one:

Nice AJ, 
I'll keep that in mind as I see spade bits at the local pawn stores in the hand tool bins for dirt cheap.

I drill from one end only.  The reason I use three bits is to get it to drill straight.  The stiff center drill gets it started perfectly straight, and with the bit on one end and the center on the other, that hole is perfectly on the lathe axis.  Then, use a jobbers bit, again to be stiffer than the long bit, to extend the hole.  Then, the long bit, and the straight hole to guide it will keep the long bit from wandering.  A pithy area or a real hard knot or a combination of them might make it wander off, but usually I'm within 1/16" or so of hitting the point of the center.

A gun drill would be the elegant answer, but I've always gotten by with a twist drill.

Thanks Dave

Time for me to “get off the pot” and just drill the stock.
