A while back someone posted excellent photos and explanation of the process of relaying shotgun ribs. I have searched for this thread and can't find it. Could someone direct me to this post. I know it's been a couple years ago. Thanks
I found it easier to view and read in the slideshow format.

Now can someone go the extra mile and provide info on the process of joining barrels at the breech end including the short rib/rib extension. I have not found a good description of this and have only read that higher temperature silver solders or brazing is used in the breech area.
