Jay,
In many cases that I have experienced with oily woods, in particularly ebonies, CA does not adhere well. It can hold and not be a problem. However I found problems on the ends, when separating the bushings from the turned and CA finished blanks. The snapping would cause the CA to lift from the blank on the ends. That is what drove me to investigate and move to TBC.
If CA is put on over "not fully cured" antique oils, I don't know what would happen but I would figure that it would cause similar problems what I had with the ebony woods.
In all fairness and logic, I have not had any more problems with CA and ebonies in nearly a dozen years, so the adhesion is not any better now than it was before, I am simply not applying the same forces on it as I was before - meaning that it might work, only it may be more sensitive to shock (drops bumps) of different sorts.
Just my opinion.
