I get really anxious and nervous if im not tinkering with something. This months project is a trotline made to my specifications. How would I go about making the plastic swivel retaining beads on this comercial trotline?I was thinking about running the main trotline cord through and egg sinker mold and then pouring liquid plastic. What type of plastic do you think this is? Any ideas on how to make and fuse these beads to the main line.
