And had the stones to post about it, IIRC. That's the one I remember, every time I ask myself if I'm "pushing the envelope" on a stuck post. There's an old '85 Tempo frame with a stuck LaPrade still sitting in my basement, still taunting me, in part because I picture your thread whenever I feel compelled to try turning it just a little harder. Fortunately it's a fairly short post, so it's a good candidate for the jab-saw option.
