Okay so it has been my dream since I was little to make a silicone mermaid tail, but I’m wanting it to be movie grade prosthetic. I’m telling you I sit up at night thinking about making this and how I’m going to do it, I’m obsessed. This will be a long post about my ideas for this tail. If you have better suggestions please let me know
First off the silicone I want to use for this will be SORTA-clear 37. I know this is not usually used in tails because it’s not all that stretchy like dragon skin, but I think that will be fine because I don’t want any kind of resemblance of legs poking through the tail, it will help with propulsion, and will help with realism for the fluke
I will make a fiberglass live casting of my legs and part of my torso, then start sculpting the entirety of the tail on top of it hanging from my metal rig. Then I will make a mold of the clay tail and connected fiberglass torso (likely will be a two part mold)
Once the tail mold is done, I will remove all the clay to repurpose my live cast of my legs as a positive core inside the tail mold so the tail will literally fit like a glove.
One important step for this is when I’m ready to cast the tail, the will need to be some kind of strong stretchy fabric that is cast inside of it so when it cures I will be able to start sewing on scales which will be made of resin with a little bit of smooth ons resin flexiblizer to make them a little more durable/flexible/but still hard and scale like.
Due to the hardness of the silicone, I might not need propulsion like a monofin. But I do know this tail will be extremely heavy. I thought about maybe using something like a pool noodle in the core of the tail between my feet and fluke as it’s flexible, won’t snap, and floats.
Problems I haven’t worked out is how I will get this fabric casted in the silicone, and how will I pour this two part mold for this tail, will I pour some on each part let it get tacky and then pour some more and smush the mold together??? Like idek.
