new Turner, still learning so all help is appreciated.
I have a Nova SuperNova 2 Chuck on a Laguna 1836 lathe. Am creating a tenon using guidance from Ken at turn a wood bowl. Tenon is about 2 Inches with shoulder 2.5" or so. Chuck seems to fit perfectly against shoulder and tenon is only about halfway down jaws. Dovetail on tenon looks good to me. There is space between the jaws and at 2" the jaws appear to be circular.
Once seated I use the handle to tighten the pinions and twist on it pretty hard to make sure there is a good grip. Both pinions get tightened with about the same force. Prior to starting the lathe all seems tight and true.
After turning for a bit, I check the pinions and they are loose.
What am I doing wrong?
