A bit confused here too. A slight wobble, yet the chalk test was good. ????? Please detail your method, this is not normal. Look for 50% contact (or better) towards the big end.
"took it out of the headstock." ??? Explain, please. If you're adapting the spindle taper, your chalk-test method comes into question again, this time on the OD of the adapter.
If you're attempting to mount a dead center in the spindle taper, this is all good practice but I use a 3/4" bar with a 60 degree point on it that I true every time. Just grab it with a 3-jaw chuck and re-point it. Lathe dog leans up against one of the jaws. Call me lazy.
