   Largely concur, my second case.  8)>>
   would add, tho:
   Sand OUTSIDE inner bit, and inside of outer tube.
   Small roll of sandpaper on rod, or file.
   Objective is to have _clean_, fresh surfaces.
   Classically, 'acid flux' is used: more aggressive than
   usual rosin flux used in electronics.
   Use 'lots' of heat.

   Just so.  How many people solder copper pipe?
