  • For the people wondering, these 4-part lessons are really a must-see if you're into animatronic building or if you're up to becoming one :) 
  • Hello, I have a ton of questions.  First question is about the Servo supply list.  It appears as though the number of Hitec HS-82MG needed is a total of 11, is this correct? 
    Also, I seem to be confused and missing a step. 
    1) Have a mold
    2) Cover it with vaseline(?)
    3) Put WED type clay into it. 
    4) Spray with Crystal Clear
    5) I'm lost...Spread plaster on the inside of the WED clay? And stick it together? And wait for it to dry?
    6) Spread vaseline on the plaster and
    7) Cover it with bandages? 
    Can anyone please help?

    Elizabeth,

    The steps you are mentioning are for creating the fiberglass underskull.  You take the mold that was used to create the skin of your animatronic character and line the inside with clay that is the approximate thickness of the character's skin, and then create a mold of that internal cavity using plaster bandages.

    With complex lessons like this, I find re-watching a few chapters (or sometimes the entire lesson) helps, since you have more context having seen more of the process.

    Here is the list of servos used in this lesson:  (form the lesson page materials list)
    • Jaw Servo (Hitec HS-645MG)
    • Eyes Horizontal Rotate (Hitec HS-53)
    • Eyes Vertical Rotate (Hitec HS-82MG)
    • Eyelids 2 needed (Hitec HS-82MG) (2)
    • Brows 2 needed (Hitec HS-82MG) (2)
    • Upper lips 2 needed (Hitec HS-82MG) (2)
    • Mouth corners 2 needed (Hitec HS-82MG) (2)
    • Lower Lips 2 needed (Hitec HS-82MG) (2)

    Please let me know if you have any other questions.

    Thanks,

    /Chris
