I am toying with the idea of pouring my own jigs. I am going to start simple, regular ball heads and see how it goes. I'll probably play around with some powder coat and see how that goes as well. Before I get started I have some concerns. I have young children, and we all know that high amounts of lead can be toxic. What precautions, if any, do you guys take when heating lead and then shaving the flash? I was thinking, at the bare minimum, of some type of exhaust hood over the work bench. Thanks in advance for any advice.
