I have turned a few knobs, both small (12mm) and larger (45mm). Most simple method I have used is a 19mm thick piece of timber screwed to a small face plate, with a coarse thread screw (particle board screw) driven through the centre of the 19mm board. Cut the blanks off square and allow a millimeter for cleaning up the top. Screw the knob blanks centrally onto the screw and turn. You will need a sharp tool and careful technique. Works well for me.

Thanks TL and Jim. You've given me a couple of ideas for what I can try next that might work without having to buy new gear.
I'm thinking a chuck like TL's mounted on a large face plate that I have might work.

I'm a bit late, but...
I turned a few cedar pulls a while back and had similar problems. Worse, once I'd finished 'em and they were installed, they were broken off the chest of drawers in fairly short order. (The customer had some rambunctious kids. )
I replaced them with another set BUT I gave up on turning the tenon as part of the pull. Instead, I drilled the blank and glued in dowels which I think I made them from meranti. But I'm not sure...
I didn't have anywhere near as many problems when turning with this approach!

A jam chuck similar to TL's is sort of working for me. At least I'm keeping the blanks on the machine, it's just my tool skills letting me down. I have however moved on from 'not possible' to 'will work eventually'.
Rather than trying to turn accurate tenons in spindle mode that fit the jam chuck, for the moment I'm simply cutting a tenon on a blank first using a plug cutter. Same size every time.
