I’m new to turning, but an experienced woodworker. I plan on turning some walnut knobs for a cabinet I’m building, however after turning the knobs round I would like to further turn them to create a fairly sharp oval shape to the knob front. I can imagine doing this on a wooden faceplate off of an off-center hole the same size as my knob tenon. But I can also imagine the knob turning in its hole as it’s shaped. At least I don’t see anything stopping that from happening. If that occurs, the knob is ruined.
Is the knob likely to rotate? If so, how does one secure the knob but then rotate it to turn the other offset? Do I have this all wrong from the start? Perhaps there is a better method.
Thanks in advance!

a , Interesting question , it may be that the piece needs to be shaped oblong to begin with , maybe two pieces then turned as one ???
keep trying dusty
I don't have any experience with this, but I figure if you put a threaded insert in the base of the knob and epoxy a bolt into the "faceplate", you could thread the knob onto the bolt and start turning. Just like a screw chuck, the forces on the knob from the cutting will only cause the knob to tighten.

This is an interesting idea and I think it would work. I intended to spline the tenon from the inside and show it so I could just turn a really long tenon and cut it off.I may get some more ideas, but this one (although a bit of a pain) would definitely work.Thanks!
Instead of a round tenon on the knob, how about a rectangular or square tenon. Also more work, but the knob will definitely not turn in the hole.Dan
