I no longer make my buttplates out of two pieces. I got a set of Southern mountain hardware from an old rifle that burned up in a fire, that had a beautiful hand forged buttplate. I was shocked to find it wasn’t riveted, and brazed together. It simply had a waste filed, or forged at the juncture of the buttplate, and the heal, that was filed to fit when folded, and forge brazed. That would almost eliminate the parts creeping when the brass flows.
