Trot,
I question the practicality of this in Ga1, but IF you wanted a
fusible plug it would involve three components, a bushing, a threaded plug,
and a copper rivet. The bushing is installed (silver soldered) into the
crown sheet during construction of the boiler. The rivet is soft soldered
into the plug, head down, and the plug screwed into the bushing. The plug
being removable and the rivet being renewable, this would avoid than making
a boiler which in order to save itself must destroy itself.
