Chucky progress!!

I recently tore all the mechanics out of my chucky prop because it was just too loud with the wiper motor and i couldnt take it. I am going to have linkage from the arm to the motor at th waist and it will be a simple arm animation. I bought an air vent motor and when it arrives i will give you all a running video of what it looks like! Heres a snippet at what it looks like as it sits. Its pretty bare:(
