Got the second side done! It de-molded fine with no damage to the sculpt.
You notice the other half is blue. We used a quick cure catalyst so I could try to prep for casting tomorrow.
The Pour Spout
Here is the pour spout. When it is rotocast, I put the plug in. There is a small hole drilled in the plug so that some of the heat can vent.
The resin gets hot and expands. The hot air would bulge the mold if it couldn’t escape. The heat and a little resin goes out the hole.
You have to put a little zip lock bag around the plug when you rotocast it so it will catch the resin. If not, the resin will fly around the room. (I learned all this from Mike Petryszak)
