The BOC library has a section on sinkers and sinker making. Here is the link just scroll down to the sinker section.does any body no where or how to make molds to make sinkers
YES! YES! YES! In face, that's so important, I recommend that you heat your mold way too hot to touch before you ever pour in that first bit of melted lead. I can show you lead on a 10' high ceiling from not doing that. I cooled off the molds with water, dried them well with a towel, and even warmed them up before pouring in the lead. Melted lead blew out all over my hands, arms, face, and even the ceiling.I'm not sure if this was told but when ever you melt the lead and make your weights be sure there is no water in the mold or or whatever you are use. Water and lead does not mix. Plus lead if spilled on your skin will burn you until it's cool or until you dig it out your skin. So the new people wear your gloves and maybe safety glasses.
