I have a mold that makes egg sinkers1/2, 3/4. 2,3,5,6 and 8 oz. I was thinking of running a wire through them and twisting the end into a circle and attach planer board clips like a homemade snap weight. I bought a bunch of clips from Russ of Anglers Ave at the Niagara Show 2 years ago. I'm going give them a try this summer. They're not perfectly round so I don't know how they are going to work.
