Anyone make rubber bait molds?

[Sundowner]

I briefly looked at some stuff online. I'm the kinda guy that needs to be able to see it happening and ask my questions then. I have 2 different lobsters/crayfish that don't have a maker on it and I can't find it anywhere online. There are the small legs, antenea, and protruding eyes that make me skeptical about trying on my own.

Thanks,
Bob
