....see I used to tin all the wires before putting them into screw clamp 
terminal blocks, but I read something a month or two ago about heating 
and cooling cycles causing the tinned wire to come loose.  The article 
proposed a compromise solution of tinning just the very tip.

I think tinned stranded wire is more subject to vibration work 
hardening, but much easier to work with and no chance of the wild 
strand causing problems.  Aircraft have all wires terminated in crimp 
type connectors as far as I know. I used to build stuff that went into 
the avionic bay.  I ought to know, but I cannot remember how we put 
the pins on the wires on those huge cannon connectors with dozens of 
pins.

I thought I read in the instructions for some device – probably either 
Phoenix or Traco – not to tin the ends of stranded wire, you must use 
ferrules or it will be the end of life as we know it.

Or, just solder the stripped wire and not use ferrules.

The crimpers are not really needed - the terminal block does a fine 
job of squashing them.   Of a pair of channel locks if you must.    
The ferrules are really just to keep wire strands from sticking out 
and causing a short and to make reuse easier.

Oh great, now I have to think about getting some.  The crimpers alone

We added some ferrules at sites...
