Misaligned Tailstock and Headstock

I have been having trouble getting a hole centered in the lathe.  The headstock and tailstock are misaligned which explains everything.   A bit of searching suggested cleaning the headstock mating assemblies (in this case the headstock and the spacer).  Problem solved!

Attempting to get the center on the mill should have been easy but it never quite worked.  Once I had marked with a center drill, I used a center finder in the mill to get 0,0, then used a 1/2" carbide endmill to get a perfectly centered hole!
