What You Need for DIY Sinker Molds
To make DIY sinker molds, you need a few key things.
- Silicone for Molds: This is a popular choice. You can buy RTV (room temperature vulcanizing) silicone from craft stores like Hobby Lobby or online. This silicone often comes with an activator. You mix them together to make the mold.
- Lead or Metal: You need lead or another heavy metal for the sinkers. You will melt this metal and pour it into your molds.
- Wood or Metal Shapes: To make sinkers in certain shapes, use wooden dowels or metal pieces. Make sure they are very smooth. If wood is not smooth, the grain might show on your sinkers.
- Glue: Use glue to hold your shapes or any swivels in place inside the mold box before you pour the silicone.

How to Make Your DIY Sinker Molds
There are a couple of main ways to create DIY sinker molds.

Using Silicone Molds
Silicone is flexible and good for detailed shapes.
- Mix Silicone: Carefully mix the silicone and its activator. Follow the instructions that come with it.
- Prepare Shape: Get your wooden dowel or other shape ready. Place it in a small box.
- Pour Silicone: Pour the mixed silicone over your shape. Make sure it covers the shape completely.
- Let it Cure: Wait for the silicone to dry and harden. This can take several hours.
- Ready to Use: Once cured, take out your shape. The silicone mold is now ready for pouring melted lead. You can see how this is done in YouTube tutorials.
Using Wood or Metal Molds
These are simpler but might not last as long as silicone.
- Make Mold Shape: Cut your sinker shape into a piece of wood or soft metal.
- Smooth It: Sand the inside of the mold so it is very smooth.
- Pour Lead: Carefully pour melted lead into the mold.
- Cool Down: Let the lead cool and get solid.
- Remove Sinker: Take the finished sinker out of the mold.
- Smooth Shapes: Sand any wood masters very well. This stops wood lines from showing on your finished sinkers. A smooth master means a smooth sinker.
- Right Mix: If using silicone, follow the mixing rules exactly. Too much or too little activator can make the mold weak or not set right.
- Level Pour: Make sure your mold box is level before pouring silicone or lead. This helps make sinkers that are even and balanced.
- Cool Fully: Let lead cool down completely in the mold before you try to take it out. Removing it too early can break the sinker or damage the mold.
