Mold-Making In Progress

So, it's been a long time since I did some mold-making, but I had a request to cast some difficult to recreate parts. This is a silicone mold and will have a second half poured on top. Once the molds cure, I can pour resin in the channels (where the white styrene bits are). These will hopefully trap air bubbles below the area of the actual railings. I'll also be pressure casting these in a pressure pot at around 40 PSI, which will significantly shrink any air bubbles. If you are looking to get into resin casting, I highly recommend the California Air Pressure Pot, which will really help with air bubbles. Not to mention, this pot is ready to go out of the box, and is super simple to use.
