Another inexpensive and simple mold to make is to use a chunk of hard wood and drill and carve out a sinker cavity. Here, too, the mold is one piece and you are limited to the types of sinkers made with the potato mold. You can make a good dipsey sinker mold from a wood block by drilling a cavity on one end with different-size drills. First start with a large-size drill and drill only a short distance below the surface. Then use a slightly smaller drill and go a bit deeper, then a still smaller one to reach the full depth you want. After which you use a knife and gouge the ridges from the cavity. Wood carving tools are also good for this work. Cut a small slot in the far end of the cavity to take a wire eye, and the mold is ready for use. Such a mold is shown in Fig. 131. It will last for quite a while before the hot metal burns it out too much. Figure 131. Wooden sinker mold. If you have a drill press or an electric drill and other metal-working tools you can make such a one-piece mold from a piece of metal. Brass, copper, or bronze are easiest to drill and cut, but you can also use iron and drill out a sinker cavity similar to the wooden mold described above. Once made, such a mold will last forever and will make thousands of sinkers.
