I would like to ask you what kind of glue you used in this reconstruction. My brother and me have brought 5 or six rifles back from the dead, all SMR. Glue is the main part of reconstruction on wood. I look forward to your kind reply.
Shortbarrel, for you, and other guys that might want to give this stuff a try, That would be Titebond III. Some time ago I did a test with several popular glues, and Titebond III won hands down. I use it for areas where you'll need some time to align the pieces and get them clamped in place. For smaller pieces where you can hold them by hand, I use a super glue made by StewMac. It comes in colors and Medium Amber is a good one for these old guns. It too is tougher than nails, and the wood will break before the glue bond breaks.
You are probably aware, but for anyone just starting to do this sort of thing, for any glue joint with these old woods, it is imperative that you clean the area to be glued really well. Clean/scrape the discolored surface off, as well as the pulpy wood, if any. Then use a sharp object to score the old wood to give the glue a solid area to adhere too. I don't want things to break apart down the road, so I score the new wood as well. Where you don't want to score it is right at the edge of the glue joint! You want that joint to be as tight and narrow as possible, and the glue line as small as possible.
In the end, to make a good glue joint, make it as narrow as possible! No matter the joint, I try for a gap of no larger than .005". Zero is better, but not always possible.

If you glue it like this, be well aware that undoing this glue joint is going to be next to impossible, so be sure you have the pieces exactly where you want them!
