This how I make my no-roll sinkers. What you will need : A scrap piece of ½sheetrock about 18 X 18 Ruler or Strait edge Pencil Circular saw Router with 3/8 bit 10 or more wire close hangers Wire cutters The amount of molds & size of each mold may differ for what you may want. I just plan to show how I make the molds not specify size or weight. You can change the size and or shape to fit your needs. With this mold I will be making 4 different size sinkers. First lay out the Sheetrock something like the one in the picture. A simple way is to use the ruler or strait edge and mark a strait line down the center. Then use a store bought no-roll sinker as a stencil. Or you can measure out each piece. Make sure to leave about ½ space between each mold. Lay out as many as you can fit or what ever you feel happy with to start off. Second set your circular saw depth at 3/16 and cut down the strait lines through the layouts. These cuts are were your wire will set when your ready to pour. Third set your router depth at ¼ and cut out the inside of each lay out. After you cut out each layout clean the dust out of them. Inspect for flaws inside each mold carefully. Fourth cut strait pieces of the wire the length needed for your mold. Place the wires slots you cut with your circular saw earlier. Make sure the wires set flat in the slots but not touching the bottom of the mold. Set your mold on a flat level surface. I use a work bench in my shop. Now you should be ready. Melt your lead and fill your molds like filling an ice tray. Let cool the use the wire to lift out the sinkers. They may still be to warm to handle so I drop mine in a 5 gal bucket of water. When cooled enough use pliers to hold and twist wire on the bent end. My no-roll sinkers look like this. Hope this helps.
