I thought I'd share this prop with my new friends on Halloween Forum. I made this last year.



This is my take on the classic cauldron stirring witch. My haunt is themed to jungles and islands, and witches don't really fit, plus I don't really like them. I have always liked the grim reaper and Charon the Boatman, so I guess this was a natural interpretation.

Before I get into how I made it, let me give a shout out to those who inspired me (ahem...whom I copied).

Also thanks to everyone in the technological terror forum who helped me get him going.

So this guy is a 1/2 pvc armature made with the Zombietronix calculator for a 5 ft skeleton. I used hardware cloth for his rib cage, and it has ribs are made with greatstuff. Inside of him is a 6rpm motor that cranks his head up an down slowly. It hard to see in the video because I kept moving around. His head is a 2 part urethane cast from a mold of a bucky skull. The rest of the bones are from a "bag of Bones" from Biglots and are attached to the black pvc frame with hot glue. The motor is the standard Monsterguts wiper motor, and I have hooked it up to an ATX computer power supply on the 3.3v circuit.

What makes him different other than being a skeleton is that his stance over the cauldron and the natural movement of the arms are due to the fact that one arm is fixed, unlike most witch cauldrons. The right arm is rigid all the way to the wrist. There it is joined by a simple linkage to the hand which is glued to the stick. If you visualize the shape the stick makes as it travels in circle, it would look like a cone, whereas the normal setup would draw out a tube shape. Since the upper hand is mostly anchored, and the movement there is minimal, the skeleton can be leaning over the cauldron without being hit by the rotating stick. The bottom of the stick has been shaped to a dull point, and rotates inside a 1 1/2 pvc end cap, filled with hot glue to prevent the stick and the bolt which attached the cap from binding.


Check out ScareFX's how-to, it was a huge help to me.

That thing is awesome! Especially with the lighting. Good lighting always takes displays to another level :) The only creepier thing I can imagine, is if his head were on a cam, slowly looking back and forth, scanning the crowd for... um.... ingredients.

- Hook
Well is goes up and down, hard to see when i am jerking the camera around. I have been thinking of putting a spring return on the neck to pull the head sideways as it travels down.

That's Awesome! I really like him better than a witch too.

Actually, I have a wall paper for the computer that's a calendar with this picture. I really liked it, but I wasn't sure where it came from. Now I know, and it's even better.

Great twist on the old standard. Mind if I copy??? lol. Are you sure it's a guy? He looks like a woman that works at my hospital. Nice work with the dual motor setup. Def adds more character.

I've seen this video several times before and am always impressed with it. It is by far my favorite cauldron stirring prop. Everything about it - the stance, the motion, the use of a skeleton, the glowing eyes, the back lighting, the painting - comes together to make it an excellent prop. Well done, DC!
