Hey guys. Looking for some help with casting. I just started, and am using my Energon axe as the first casting test. I made the rubber molds last week, using Smooth-On Mold Max 30. It seemed to turn out good. I tried casting, using Smooth Cast 325. Since its neutral color is a translucent amber color, a friend suggested it be great for the axes, especially with an orange dye. So I tried casting the axes, and its not turning out too well. I keep getting the top of the axes not filling up with the plastic, or sometimes the big sphere won't fill up. Plus, the casting has tons of microbubbles inside the plastic. The Smooth Cast 325 has about a 2 min potlife or something. So I mix Part A and B together for about 30 seconds before I start pouring. Anyways, any help or advice on how to fix these issues will help. Also, should I just invest in a Vacuum chamber? Especially for translucent parts?
