Thank you. I guess that is another vote for Dog.

I am not sure but I think the crank mechanism you did on your peeper is a better mechanism then the ones I have in my dog. But, for some reason the crank mechanism typically used seems to bind for me. Or they can torque out of whack. I really ended up with this slotted mechanism because of desperation when the lear mechanism was giving me fits. It seems to work pretty good though. And I mentioned to someone else that for some reason I think the one I used seemed to be a little more compact(especially the one in the jaw) even though I think they have the same motions.

I started making teeth for Wolf/Dog. I have two pieces of 1/4 inch copper tubing bent to form the "jaw". One for the upper and one for the lower. This goes along the inside of the mouth in u-shape. Now the question becomes what do I use for teeth. My first inclination is to mold clay to the tubing and then cover the whole thing with epoxy to get it to adhere to the tubing. Then paint them white and wire the pieces to the respective jaws. Another concern is getting the teeth to overlap when the mouth is shut. I also plan to caulk between the teeth and jaw with black caulk so it looks like gums. I accidentally go some caulking around the mouth last year and it looked pretty cool.

What did you use to open and close the mouth. It didn't look like a servo but it worked well.

It is a low rpm motor out of an appliance. I wanted to convert Wolf/Dog and some other props I built over to servos. I just haven't figured out the best way for me to control servos yet.
