Elliptical path on wheel rim?

John Hill:
How do I machine an elliptical groove in the rim of a wheel?  I dont even know if elliptical is the right word but I want to machine a groove in the rim of a wheel so that I can get movement parallel to the wheel's  axis,  sort of like the action of a swash plate.

Thanks

John

Bluechip:
What? Barrel Cam ??

Similar to pic ?

Dunno, John. Tried to do it myself a couple of years ago with a uController, 2 steppers , one on a rotary table and t'other on the x-axis but although the principle is, I believe, sound my attempt was not too good.

Did work but the set up needed much more refining and was abandoned.

John Hill:
Yes Bluechip, something like that!

Fergus OMore:
Maybe Ornamental Turning is what you are looking for. Elliptical chucks?

There's a Society in the UK. Maybe- Charles Holzapffel and Ornamental Turning. Tubal Cain did a book on the topic as well.

Regards

Norman

 

JohnC:
If you put the wheel on a faceplate and packed up one side you could use a parting tool to cut a groove perpendicular to the lathe axis but angled to the wheel axis.  Tried to post a sketch but failed, will try again!
