8. Complex Casting

Time is key in the Molding or Casting process.  Many of the processes have one chance to be done right. Scheduling out each step helps:

Mold setup
 clamp, secure, glue or otherwise sure the 2 or more parts of the mold.
 Test the mold with water.
 Measure the water for mold size
 Dry the mold
 Apply mold release
 Re-secure the mold.

Preparing for the unexpected:  leaks, spillage, under pour, over pour, etc.
 Cover surfaces it absorbant brown paper
 Have paper towels ready
 Put on PPE as needed (gloves, masks, face shield, etc.)

Prepare materials before mixing:
 Do the math. 1/2 A, 1/2 B
 Measure each part in a seperate cup.

 Set timer for pot life
 Scrape the side and bottom

 place mix in the degasser
 secure the lid, shut the release valve and turn on the pump.
 keep a eye on the pot life timer, always complete the process before the timer 
 wait for the bubbles to stop
 open the release valve.
 Smooth pouring will reduce bubbles. 
 Pour starting in the low point.
 Observe - watch for leaks, spills, until the end of the pot life

Mold / Casting storage
 Put the in process work in a safe area where for the cure time

 open the mold and pull out the cookies

 keep "objects" out of the process that aren't helpful. reduce hazards.
 remove spills before material sets when possible.
 Carefully dispose of waste.
