I have a 10" South Bend lathe (serial RKL) that I'm

The shaft was probably flexing since you were not supporting it with the
tailstock.

Nope, workpiece deflection would make the free end bigger, the headstock end
smaller. On most lathes the headstock cannot be adjusted, it has
vee ways on the bottom that fit to the bed ways.

The tool can push the free end away, or (if it has aggressive rake) can pull the
free end of the workpiece toward the tool. It doesn't always make the free end bigger.

While a headstock cannot be adjusted, it's possible the bearings can
be shimmed or adjusted (don't know about this model in particular).
