Thanks guys, i'm going to take it apart tomorrow and try to heat it loose. If no luck i'm sure some stern tapping might be in order. hopefully with some sanding and filing this will be the last time i have this happen. Again many thanks!
Using anti seize or lubing them just defeats the purpose for which they were designed. I have a metal lathe with a jacobs chuck with a MT3 taper for the tail stock. Typically I can just 'slap' the chuck in the tail stock and all is good. Sometimes I smack the chuck nose with a leather mallet for good measure. Particularly if I'm drilling 1/2" or larger. Of course my tail stock has a self ejecting feature which makes removing them easier.
