What would you say, can one run a 230/440v motor that is 45 years old,

I had a bad experience running a 230v only motor of a similar vintage,
due to current leakage. The 440v motors, though, have better
insulation.

I would really like to run this lathe from a VFD as opposed to the
phase converter.

Given your proclivity for this sort of thing, you ought to be smart enough
to just move.
Yeah, it's a pain but so what?
Make your life look like your end game, or desires.
