Chest Emblem Mold

Progress has been made on the mold of the top plate of the chest emblem.

Here's how the top half looked when I pulled it out of the box. I needed to cut a thin layer of silicone out.



Here is the back half. I'm going to use a brass rod to cut vents into the mold. This will allow air out of the mold when it is curing, so hopefully no bubbles.



Here's how it looked after the vents were cut.



The next step is to run a few pulls out of the mold. Two sided molds like this always take some time to figure out how they work. You need to play around with it during the pouring process to see where the air pockets tend to gather, and if necessary cut more vents or figure out a way to work around them.
