How to Make Soft Bait Fishing Lures

Interest in your fishing hobby can be greatly expanded if you add an ability to make your own soft bait fishing lures. Making the mould and casting the resin is not a difficult process and can be done with a minimum of expense and equipment.

What makes the process so attractive to many, is that once you have learned the process, there is no need to restrict yourself to making reproductions of naturally occurring bait.

Increase the fun and expand your interest by modelling a unique design of your own. Air hardening clay is the perfect modelling medium and silicone moulds reproduce every detail. Models can also be made by whittling the original from wood or carved from wax.Use whatever material with which you feel most comfortable.

Steps to making the Faux Lure:

Model Selection:

Start your fun by acquiring an original model from which you are going to make a mould. The model can be an actual live bait or as explained above a model you have made yourself.

The Mould

The mould itself will be made from liquid silicone RTV (Room Temperature Vulcanising) a silicone that will flow around the model in a liquid state and after a period will conform to the shape of the mould and set firm but flexible, for easy removal of the resin faux bait.

Types of Moulds

Depending on the size and shape of the model, the mould can be a one piece mould which has a flat back or base or a two piece mould which reproduces 3D shapes completely.

Pouring the Mould

Being a liquid the silicone rubber must be poured onto the model which must be surrounded by a wall to contain the flow. The wall can be wood, plastic, metal or even a suitably shaped container.

The Resin Casting Material

The Alumisol Soft plastic that we recommend is a virgin vinyl that requires heat in either a microwave or on a stove, to form the soft lure. This is explained in the instructions that come with the material. It can be dyed, recycled or made to any degree of softness by adding a softener. The lifelike appearance of this faux bait in the water has to be seen to be believed.

Casting the vinyl

It comes as a white liquid which should be shaken well before heating in a metal pot on a stove or in an approved microwaveable container in a microwave.

As the vinyl expands slightly on heating, ensure that your container is large enough to cope your mixing action and with this expansion.

Full manufacturer’s instructions on the heat processing of the plastisol comes with the product.

Once the plastisol has reached a clear and pourable consistency you are ready to add decorative material if desired.

Decorating the Faux Lure

Decoration of the lure can take the form of dyes or additives such as metal powders or mica flake or the new Alumidust powder colours.

Once the decorative material has been mixed in thoroughly you are ready to pour the plastisol into the mould. Keep stirring gently right up to the time you pour the plastisol into the pre-warmed mould. Avoid vigorous mixing that can beat air into the mixture.

Safety Precaution: Once poured, allow the plastisol to cool fully in the mould. It is all too easy to get burns if you demould too quickly.


When you have removed the faux lure from the mould you are now able to trim your piece with scissors. Cut the flash off from all pour areas and edges.

The piece can be further decorated at this stage by use of an airbrush or brush. Most any paint can be used but most prefer water based acrylics for ease of use. Finish with a acrylic gloss or matte spray to seal.

Kits are available for either hard or soft bait fishing lures and provide an easy way to master the art of making fishing lures and adding another level of enjoyment to your hobby. Happy Fishing!
