Organ Grinder: Head Mold pt.1
After completing the head sculpt I built a wooden box around it to create the plaster mold. Many people have different ways they do this, here's how I roll:
A) Pour first half of plaster up to the ears. Set ping pong balls for keys. Let harden for approx 2-4 hours.
B) Prepare hardened mold for 2nd half of pour. Remove ping pong balls, cover surface of mold with release agent (Crisco works fine). You can see I set screws into his pupils. That is so that the screws will anchor to the second half of the mold and pull out of the clay head upon separation. They need to be in the mold when the silicone rubber is poured so that the eyes will create eye sockets in the silicone rubber.
C) Pour 2nd half of mold, let harden for approx 2-4 hours.
D) Remove wood stocks and gently separate mold with a flat head screw driver. Lastly, clean mold thoroughly with soap and water.
Thanks for chekin' me out! Comments welcome!
