Skull construction part III

Another week with not much results, but many hours spent on it.  I've started with the installation of two new lights which are on top of the helmet.  I put them in place the same way i did for the eyes (view last week post).  The only difference is that the LITE-BRITE pins are sideways.  I'll have to adjust the LEDs because they bring much more light than the eyes.

Here are some pictures

 

  

Than, i started working on the jaws mechanism.  My first idea was to put a hinge on the bottom jaw and to use aluminium wires as resistance.  It wasn't a good idea.  There's too much weight to get good results.

I was a little angry that night and couldn't find any alternative, so i ask for advices on stopmotionanimation.com .  The next day, Boy Oyng sent me this drawing and hope came back.

 Back to work, i made this according to Boy Oyng's drawing.

It was much better, but something wasn't right...  I forgot that the bottom jaw joint should be just under the skull and not low as i made it.  After taking apart this mechanism, i begin to build a third one using the same principle.  This time, it came out as i wanted it.

 

 

 

Here's a quick test of the jaws mechanism.

This week, i plan to start building the teeth and to add some shape on the bottom jaw.
