Circuit boards were often found with the parts I needed, but
unsoldering was tedious.

clamped one edge of a circuit board into the bench vice on my fathers
workbench, heated the solder side with a propane torch, pulled back on
the board to apply tension, and released the board when the solder
sorta melted. Parts, pieces, and solder would spray all over the
place. ...

Too Cool!

Torch and pliers with through-hole. Just pull off what you want.

When I was pre-teen I needed some wire. I found some...it was on the coil
of my dad's T/R relay...on the rig he had been using! I think it was a
common "telephone" relay, so not a really big deal to replace the coil, but
he had a fast break-in system using these relays and it probably was
carefully adjusted to sequence the contacts for Rx, Tx and antenna
switching. Don't remember the consequences. Maybe the concussion wiped
out that memory (just kidding).
