For the next step, I had to put the silicon back together, and then rubber band it before pouring in the resin. As seen in the picture above, when pouring the second half of my silicon, I did not leave enough room in my foam core box to pour the silicon fully over my mold. So when I placed rubber bands over my mold to hold it together, I also placed a piece of plywood over the back to reinforce this area of the mold. When my mold was sealed, I started my first pour of resin into the mold. After the pouring was complete, I placed my mold in the pressure chamber to help get rid of air bubbles as the cast formed.
Is this a good/useful/informative piece of content to include in the project? Have your say!
