It won't go out of center in storage. If it was fine before, it should be
fine now. The first thing to check is if there if there is anything that
could cause the drive center to seat improperly - dirt, sawdust, burrs
either on the spur center or inside the morse taper in the shaft.

Another test it to put the spur center in the shaft, bring up the tail
center, rotate the shaft, and mark the high spot on both the center and
the shaft. Then rotate the spur center 180 degrees in the shaft and find
the high spot again. If the high spot matches the mark on the spur
center, then the problem is with that and the lathe is fine. If the high
spot matches the mark on the shaft no matter how you position the spur
center, then the problem is somewhere in the headstock.

You weren't by any chance talking about the alignment of headstock to
tailstock were you? The tailstock has a slight amount of play in it. See
if you can wiggle it into alignment. The headstock on the 46-700 rotates.
There is a big allen head bolt underneath. Loosen that and rotate the
headstock into alignment.

Give all this a try and get back to us with the results, and we'll go from
there.

i own a Delta 46-700 which has not been used in a few years. i
purchased it new, and worked fine when last used. now, when i power it
on, the headstock's morse taper turns off centre. is there a way of
adjusting this without returning the unit to delta?
