"Planishing" is the word. You wallop the eye with a hammer, holding a
bigger hammer or lump of metal supporting it opposite the hammer blows.
Penetrating oil won't hurt, but I don't think it will make the slightest
difference, any more than spring pressure will. The objective is to
distort the eye ever so slightly, at which point the tapered pin will
just fall out.
