My 3 axis skull...in progress

I have a couple of pictures of my prototype. I will take a bunch of new pictures as I make the other three skulls, but this should give you an idea of what I am doing.

I am making a singing quartet based on (That means idea stolen from) Mike C's Graveyard Quartet. Ever since I saw his video I couldn't get it out of my head.

A neighbor of mine with a machine shop has helped me with the prototype, machining some of the parts I needed, and helping with the design.

I have been using the prototype to do some programming to make sure it all works with Brookshire's VSA software. So far, so good. I will post detailed pics of every step as I start making more skulls, but for now, here's a couple of basic shots with labels on them.

The Jaw servo was not mounted yet in this pic. It is in now. You can see the mounting screws and the linkage wire in the pic. The servo mounts standing up on end. I will add pictures of that later. The eyelid servo is mounted under the plexi-glass. That one is not hooked up yet, but when it is, it will be attached to one of the eyeballs...I am using wooden balls for eyes. It will move it up and down, not side to side. The purpose is to make it appear that it is blinking. I have large fake eyelases that will be attached to the eyeballs. When the eye is moved down, it appears to be closing as the top eyelid moves down with it. In the pic below, you can see the slot cut in the eye socket where the armature will go to move the eyeball. Don't worry, I will post pictures of that as well. I am using a 3/16 rod end as the gimbal which allows movement in all directions. When I build the next one, I will have clear shots of that as well.

Feel free to ask questions, and I will answer as best I can. I now have it hooked up to VSA and it is working very well. I am using the lightweight Pirate Skull and so I do not need springs, elastics or counterweights.

Thanks. The store is now open and ready.
Wow Bob! You've made incredible progress since your last post in Oct...I've been planning on buying a small 3d printer this fall to toy around with animatronic projects....I noticed on your photo at the store your standing beside a Stratsys printer which is incredibly expensive....The only person I know that personally owns one is Jay Leno.....Did you buy that for this endeavor or do you have access to one?.....Feel free to ignore that personal question, I'm just being curious and a little jealous either way LOL...Once you get going and established, you should look into doing a 3d printed raven!....That's also on my 3d print wish list.....Also think about updating your link from sindy skinless to your new site so every time you post, there is a link....I would've used it at least 3 times already....Congratulations on your business start up!.....ZR
Thanks for checking it all out! No, that's not my own personal machine. I have access to it at work. I do have outside 3D printing sources now that I am done prototyping.

Thanks for the heads up on my signature link. I had forgotten to update that.

That's really cool Bob....I've been re-visiting all the 3d sites this weekend and ended up placing an order this afternoon for a Prusa i3 MKllS kit with the multi-material upgrade...My sister has one and loves it....Definitely not for everyone but I've been researching for over a year now.....I've seen many bits and pieces - working eyes/lids, hands but yours is the first working 3 axis skull I've seen printed....Thanks for pushing the limits.....I know it's a long road but you've inspired me with a working proof of concept.....ZR
