Hi guys,
So Tauruck "the man" has shown us how to make moulds! I have been experimenting with different materials and it has been a long process. I found that although it is easy to cast resin or some of the plastic composites, there is a need for a popper or stick bait that either floats or needs to be weighted to give different actions in the water.

One of the materials I have been experimenting with is foam. I have used various polyurethane foams and one material in particular is RX66F from Resichem. This is the same stuff used to make saddles so it is tuff but still floats.

Here is a before... Foam popper. This one has been weighted 1 oz in the mid  section and sits 2/3 under water and level. A barrel sinker was loosley tied to the main wire so it lies in the belly. No need to bopa it on because the foam holds it in place.

Once I had spent weeks figuring out the correct foam and method I had to have a break from making poppers. So got the compressor and airbrush out.

A silicon mould was used to make this but I discovered there is a trick to it. When pouring the foam in, the mould must lie at about a 30 degree angle. Else the foam expands too fast near the bottom and deforms the mould. Ideally a more rigid mould would work better.

Thanks, I actually enjoy doing it. I just wish I had more time on my hands! Just to paint that believe it or not takes a lot of time. That popper has about 10 coats of paint on it! And then to make matters worse, I have zero patiance.

Howzit,
Thanks. The foam is very strong. It is the same stuff they use to make saddles from. When casting it, I found tht the mould must be laid at an angle and although it can be demoulded after about 5 minutes, it is best left in the mould over night. Then leave it out over night for any residue fumes/chemicals to escape before painting. If you try painting it too soon, the paint just makes spots and bubbles. I learnt the hard way.

I started painting another 2 last night and will continue next week.

I'll start a new mould soon as well, a rigid mould for more precition moulding of the foam.
