From a riggers point of view, when doing a Ferral and thimble copper swage before swagging the wire must be the diameter of the wire sticking out at the end and when swagged there should be some unswagged wire sticking out the bottom. Why you may ask..... the unswagged wire is not compressed and will not slip through the copper if it happens to slip. When swagged by a Hand swagger have a habbit to slip under tention. On our "toy boats" we never meet the breaking strain of the wire. Wire breaks due to fatigue.

Its a pain with it sticking out but you can put heat shrink, or self evolving tape around the swage.
