Best way to "go oval"?

John i have made a couple of models of this type of chuck and noisey is for sure and i see why when one sits and thinks hard how this chuck works you get it in your head and you think you have it then when you build there is definitely a noise there is slap in the design in other words for a moment the faceplate does not touch anything then suddenly reengages i have not done this with a full size version yet but im thinking a rock tumbler attitude be the approach noisey as **** but go with it ill up when the large version is done.
