>>back in the 1930s, and later (as noted in Heathkit manuals) it was always stressed that a strong mechanical connection was necessary; that the solder was not to be the mechanical connection, just the "mortar" for the join
All the way into 50s and even 60s, Soviet radios were made using the free-hanging parts, same as the US, with one major difference: the connections were not soldered but welded.
I did not know this, until one day, as a kid, I was trying to desolder something, and all my iron did was removing the patina and showing shiny brass-looking surface.
Only later did I found what it was.
It sure was strong mechanical connection. Without any solder.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
