Jigsaw Billy Pupett Mask-Need Help

[Clow]

Hi everyone!

I'm very sorry to bother you all for this, i wouldn't if it wasn't really important ><, but somhow my brain is not fonctionning to pick up the right mecanism.

I am planning on doing the billy Pupett Mask from SAW the movie, With a movable Jaw.

I searched online for tutorials, but couldn't find anything really helpful ><

Here's a reference image of it :

JIGSAW MASK

The sculpture part really wasnt a problem, i figured i should mold and cast the mask with a separable jaw, obviously, but the mecanism for it to move up and down (when someone's talking? with the help of the person's jaw maybe?)...remains a mystery Y_Y

I would be really gracious to anybody who could gimme a hand with this..

Thank you so much,
Clow :confused

you could use a chin strap pulley, just have a strap on the bottom of the chin that pulls down when the wearer opens their mouth, put a wheel or ect near the nose that pulls the bottom of the mouth up so it pivots

I second that. A chin strap mecanisem would work.
