Does the point meet the one you made at the tailstock when you chuck up? If
not, you've got misalignment. Could be chuck, could be what it's mounted
to. A point in the headstock should meet a point in the tailstock.

That is what happens. Actually, never mind the drill thing; it distracts
from the problem. If I do this:
1) Rough a cylinder between centers using spur and live center
2) Cut a tenon (parting tool)
3) Remount cylinder using chuck (Talon)
4) move tailstock back to cylinder.

in (4) the tailstock live center will not line up with the old point.
Now the tail stock has some play (it is not an exact fit between the
ways), but even the play is not enough to make line up. In my mind, this
would indicate the head is not parallel to the ways; how would one go
about fixing this? Of course the chuck could be bad too, but it is much
much better built then the lathe.
