I've tried various methods I know to try break the live centre out of the tailstock spindle. Nothing works. The only thing I thought of was to purchase the replacement parts. Mike told me his cost is close to $190 and he doesn't know how much to sell me... At this point of my life, I have to be careful with my outlay.
