I started this plug with wood. first maple in the 16/17 winter, then ayc the following winter, then started molding them last year, and just recently made a better mold where I took my time with the little details, and some fellow surfcaster's feedback after using the plug for themselves.
In the pic, the top one is ayc, which worked well but eventually the nose would bust open from contact with rocks. The second and third from the top are last year's mold, when I cast that mold I suspended the plug in my mold "box" and poured the silicone to mid-line with the intention of a 2 part mold. You can see on the green one all the air bubbles it trapped in the mold, and thus every plug I made was a one sided rough-side lol. The bottom one is the new mold, and you can see the small white spot on the base of the plug where the pliers are just ahead of the swivel... that is the original swivel position. In the new mold I simply added another swivel location.
