How to Make Soft Plastic Fishing Molds

How to Make Soft Plastic Fishing Molds
Fishermen love soft plastic fishing lures for their effectiveness. These lures are not only good visual imitations of fish food sources, they also feel realistic. This means fish strike the lures and hold on longer, giving fishermen a better opportunity to set the hook. You can make soft plastic fishing lures right at home, making it easy to create custom lures matched to your local fishing conditions.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:
  • Polymer clay (which bakes to harden) Petroleum jelly Small aluminum pie pan Plaster of Paris Sealant (Mod Podge or similar) Paint brush Small scraper (available at most craft stores) Putty knife
  • Polymer clay (which bakes to harden)
  • Petroleum jelly
  • Small aluminum pie pan
  • Plaster of Paris
  • Sealant (Mod Podge or similar)
  • Paint brush
  • Small scraper (available at most craft stores)
  • Putty knife
Step 1
Decide on the shape of the lure that you will be creating. Many fishermen will use a favorite lure as a guide. Base yours on an effective local lure or browse through lure catalogs for ideas (see Resources). Once you have settled on a design, form the lure in this shape out of clay. Place the clay in the oven and bake according to the manufacturer's directions so that it hardens properly.
Step 2
Apply a coat of Mod Podge or similar sealant to the clay lure with a paint brush and let it dry. Use your fingers to spread a thin coat of petroleum jelly all over the clay lure.
Step 3
Mix some plaster of Paris according to the directions on the packaging and pour it into a small aluminum pie pan, filling the pan 1/2 full. The pie pan needs to be just large enough to comfortably hold your lure with a few inches around. Press the clay lure halfway into the plaster mix in the pie pan. Do this within 1/2 inch of the edge of the pan and make sure that the top 1/2 of the clay lure is not covered by plaster. Allow the plaster to harden fully.
Step 4
Apply a coat of petroleum jelly to the top of the dry plaster. Pour fresh plaster on top of the dry plaster. Use enough to completely cover the lure. Allow it to dry.
Step 5
Turn the pie pan upside down very carefully and slide out the entire mold. Separate the two layers of plaster by gently inserting a putty knife between the layers and working it around the edge while gently prying. Do this carefully, a little at a time, to avoid breaking the mold.
Step 6
Make a pouring hole. Put the two pieces of the mold together and mark both pieces where they come together, inside the mold and outside; aim for where it will be easy to pour in the liquid plastic for your lures. Then, with a sharp-pointed scraping tool, similar to what a dentist uses to scrape teeth, scrape a groove from the inside of the mold cavity to the mark you just made on the outside. Do this on both pieces of the lure mold. These two grooves are in effect cross sections that will form the pouring hole when put together. A 1/4 inch diameter hole is usually sufficient for pouring. In a similar fashion, make a venting hole. Make this hole a little smaller in diameter and on the opposite side of the pouring hole.
Step 7
Apply a coat of sealant to the inside of both mold pieces and allow them to dry. Once dry, your mold is ready to use.
