How to Make Molds for Fishing Weights

How to Make Molds for Fishing Weights
Many fishermen enjoy making some of the equipment they use out on the water. Custom-built rods, homemade lures and raising bait worms are all examples of how fishermen have traditionally gotten involved in their sport. Use the following information to make your own sinkers to your custom specifications.


Difficulty: Moderately Easy

Things You’ll Need:
  • Polymer clay Petroleum jelly Small aluminum pie pan Plaster of Paris Sealant Paint brush Putty knife
  • Polymer clay
  • Petroleum jelly
  • Small aluminum pie pan
  • Plaster of Paris
  • Sealant
  • Paint brush
  • Putty knife
Step 1
Make clay models in the shape of each of the sinker types you wish to make. Use any of the favorite sinker types you currently use as a guide. Place the clay models in the oven and bake according to the directions on the packaging. Remove and let cool.
Step 2
Apply sealant to each of the clay models with a paint brush. Let them dry fully, and then cover each one with a light coating of petroleum jelly.
Step 3
Mix a batch of plaster large enough to fill half of a small pie pan. Pour enough plaster into the pan to fill it halfway. Place each of the clay models halfway into the plaster so that the top halves are not covered in any plaster. Wait for the plaster to harden.
Step 4
Smear a thin coat of petroleum jelly over the top of the dry plaster. Mix another batch of plaster and pour it directly on top of the dry plaster in the pie pan. Make sure to cover the clay models in plaster fully. Allow this second plaster layer to harden.
Step 5
Turn the pie pan over slowly and carefully slip the mold out. Take a putty knife and insert it in the crack between the two layers of plaster. Gently work it around the edges of the mold and pry them apart.
Step 6
Remove all the clay models from the mold (save them for future use if you will be making more molds). Apply a coat of sealant to the inside of the mold cavities. Allow them to dry, and your molds are complete.
