I'm not sure who it was, Metis, but there remains quite a bit of oily residue on the lathe frame, the tool rest, and especially the surface of the bench behind the lathe. Please take a look at the space and see if you can do anything to clean it up beyond what I did (which was to wipe up the majority of the visible splash drops, and whatever was on the motor housing).
For all: When sanding or applying finish on the lathe, the tool rest should be removed, and perhaps some paper or other drop cloth could be used to minimize the "splash" that occurs during the rotation.
In our shop, I see little reason to use finish on wood while it sits on a tool. Mineral oil, as one example, may not ruin wood; unless the woodworker intends to apply a water-based finish. Then, the oil may prevent the polyurethane (for example) from bonding appropriately, or at the very least potentially cause the oil-stained area to be discolored in relation to the rest of the piece. If wood is tainted with any oil (or glue, for that matter) prior to staining or dying, this can also cause noticeable difference in color.
