I suspect however from what you say that the headstock is not locked down in
perfect alignment with the tailstock. I've used rotating head lathes for
several
years and finally settled for a double ended Morse Taper to ensure the
centering
of the lathe headstock and tailstock

Double ended morse taper?? I never knew such a beast existed; now that
would be just the ticket. I have been trying to figure out how one would
get the two parallel with each other. I will have to track one down.

If the misalignment is not too great, you can turn on the lathe before
bringing the drill up to the wood. Allow the wood to self center the drill
and then lock
down the tailstock.

Ahh, also a great idea. Never thought of that. Some things to try.
