[Boatanchors] Desoldering Components

[Jim Haynes]

Another possibility is to ignore the old dictum that the joint must be
mechanically sound before the solder is applied.  Which is the reason 
component leads are wrapped around the terminal lugs in the first place.
Just lay the new component lead on the terminal lug while applying the
soldering iron, after applying a little fresh solder to the new component
leads.  If the component is not massive and subject to vibration the
joint will probably last a lifetime.
