This Instructable covers the construction of the snout for a donkey mask.
With an effective donkey mask you can:
-Play a practically-themed joke on a farmer
-Scare your dog
-Promote the Democratic Party
-Rob a bank
-Make an ass of yourself
-Get a discount on your entrance to a furry convention
This project was created at TechShop.
Step 1: You Will Need:
-Two-part silicone rubber
-Two part soft urethane expanding foam
-A fine-toothed sawblade
-Proper mixing containers and tools
Step 2: Sculpture
Step 3: Into the Real World
With both halves complete the donkey head takes shapes in the world of the physical.
Step 4: Casting the Snout
Step 5: Add a Release Agent
Step 6: Mix the Urethane Foam
The two parts are to be mixed in a 2-to-1 ratio. A fast a thorough mixing is necessary for optimal results. I am using an electric mixer on a cordless drill. The foam has to be poured after 30 seconds then left to its own devices.
Step 7: Watch the Urethane Expand
Step 8: Release the Part
Step 9: Cutting and Trimming
Here I am cutting open the mouth and hollowing-out much of the shape to create an even more responsive part.
The superstructure was vacuum formed in PETG plastic over the MDF forms.
Urethane foam can be painted with airbrush paint, either using an airbrush or a standard paintbrush. Hair can be punched and glued into it as well.
