Making Simple Soft Plastic Worm, Fishing Lures

Making soft plastic worms from the modelling process through creating a single sided silicone mold and pouring the final worms in soft plastic. With a touch of perch fishing thrown in.

RTV Silicone For Making the mould
The product I used in this video was Polycraft GP-3481-F RTV Silicone which is a two part kit of
silicone and catalyst which sets the silicone. There is a huge range of mould making silicones out
there with different properties; often the companies that supply soft plastics for making the lures
will stock a RTV silicone to suit the home user making things easy. If this is not the case then the
main properties I would look for in a silicone is that it is 1.)condensation cure rather than addition
which is more expensive and reacts with lots of other materials. 2.) It can be hand mixed and hand
poured and does not require vacuum degassing. 3.) it has moderate flexibility when cured so the
master can be easily removed.
The most important part of any RTV two part kit is the instructions; I would not like to guess the
amount time I have wasted because I had failed to read the instruction properly.

Soft Plastics (plasitsol)
Soft plastics require some health and safety considerations especially if like me you are planning to
cook them up at home. Again following the maker’s instructions is vital. As a rule I use a respirator,
gloves and cover up arms and legs; this may seem over the top but I like my arms, legs and lungs. If
the weather is fine I cook up outside. Most soft plastic can be heated in a microwave or on a hob in a
pan. Most Manufacturers recommend that you do not use a microwave that you will be using for
food preparation, I bought a separate microwave for this which cost me £30 brand new from a
ASDA/Wallmart . Again refer to the instruction for heating times.
