Homemade Lead Sinker Molds

Updated November 21, 2016

A lead sinker is commonly used as part of fishing rigs for a wide range of fresh and saltwater game fish species. The Carolina rig, Texas rig, drop shot and bottom finder rigs all use various sizes of weights to get bait down to fish. A homemade lead sinker mould can be made at home with the use of items that are commonly available and perhaps even prove to be a bit of a surprise.

Select a tablespoon, teaspoon or other-sized spoon for use as a lead sinker mould. Choose the spoon size for making a flat type lead sinker that is often used when fishing in both fresh and saltwater. Pour molten lead into the spoon, allow it to cool and remove. Punch a hole in the lead disc with a hammer and nail to provide a tie-on point for line.

Cut a potato in two with a sharp knife. Cut the potato around the middle and not along its length. Use the potato for making simple weights that include rectangular, dipsy and pyramid sinkers for saltwater use.

Cut a pyramid shape into the potato half with a knife. Form the top of the pyramid down in the potato with the base at the top where the potato was cut. Pour lead into the potato and allow to partly cool. Place a sinker eye in the centre of the pyramid base so that, when cool, there will be a tie-on point for fishing line.

Create a mould for lead sinkers with wood in much the same way as the potato half. Create the shape for the weight with various size drill bits or a carving knife. Begin forming the shape with a larger drill bit and switch to progressively smaller bits based on personal preference. Shape the wood with a carving knife if desired for more detail.

Mix plaster of Paris with water and pour it into a shallow container. Allow the plaster to partly harden and press weights such as disk or strip weights into the plaster to replicate the shape. Allow the plaster of Paris to dry completely overnight and pour molten lead into the plaster mould to create unique weights.
