Merman Marinus SLOW Extended Tail Project

Exciting! I spoke with her and I believe maybe in a few months I can place an order since my birthday is soon I'll have a good advantage with family member birthday money! Now I will hopefully have a tail too for when Marinus visits!

Ill be making my leg double sometime this week and filling it with expansion spray foam i know already I've seen a few mers put too much ill do it in small batches until it's filled im also going to put a pipe through it so that i can either make a stand for it or hang them up with hooks from the ceiling well see.

The expanding foam has a tendency to expand too much at first, then the next day, you'll find it has contracted a lot as well. Experiment with a small prototype, so you can see the coeffient of expansion and calculate from there.

[Marinus Mortimer]

Ill test it thanks PearlieMae i hadn't thought of that!

i literally stabbed my dtd with a kitchen knife in a rage after expanding foam repeatedly ruined it. I don't know if a coefficient would have helped. That stuff is the polymer incarnation of the devil himself. Please just don't.

Im going to try once if i fail I'll consider another rout

I'm sure it will work out. I have no doubt that you, and by all means Pearlie Mae, could definitely make great things of expanding foam my problems with using materials have many layers, definitely one of them being my lack of both of your mantras. 'Slow' and 'test test test!!' Do not come naturally to me. I'm working on it but- it's a process, lol. Good luck!!

[Marinus Mortimer]

Yeah its definitely a matter of patience for these things i my self am not so good at it usually i just walk away for a little while to relax and not smash everything when it doesn't look how i want it to.
I made two leg duck tape dummy one for mazu and one for me i bought 4 big tape rolls so i had plenty of tape ill be getting the foam sometime this week ill also make a little dummy of my feet to experiment on first before i go for the big one im sure its about applying small amounts very small and wait at least 24 hours between applications so like PearlieMae said it can have time to shrink so i can get it right but yes test test test

Yeah in terms of smashing everything when it doesn't work out, I mean...don't knock it til you've tried it. Lol
in seriousness you are doing an amazing piece and I look forward to seeing it come together. I love your sculpts

[Marinus Mortimer]

Aweeee thanks Merwandering that means a lot coming from an amazing artist such as your self

Also i found this while searching the forum its a great idea for filling the leg mold and it worked great in the video i might try this foam before i try the troublesome spray foam thanks a lot for the great advice guys!

This is also a good way to keep the spray foam from warping the mold although he did put a bit two much at the beginning i would have worked in layers of small amounts allowing each "batch" to cure completely

I have found that the foam stuff does not for some reason work well when making a body double. It tends to distort the form.

[Mermaid Fenicia]

I use bubble-wrap and other packing materials to stuff my tape-double, as it's light weight.

The liquid stuff? What happened in your experiment ? The reason im looking for a way to fill it so that it stays stiff cause on top of the leg double i will be sculpting the tail body on top if it so i need it to hold its shape under the continuous pressing and sculpting on top of it you know so if the fence post stuff is a bust ill be going back to the spray foam idea ill do it slowly allowing each batch of foam to rise and fall like dough ill also follow the bald guys instructions and get the one with the lowest expansion rate that way ill kind of have a bit more control, im doing this as an alternative to spending a butt load of money on plaster bandages to mold my legs and then the resin plus fiber glass to make the cast that for me is a whole new ball game as ive never experimented with resins before so ill try my damm hardest to make this successful if all else fails ill invest in the above... wish me luck

you can do exactly what you've done here but instead of using tape you use fiberglass that is activated by water. (the type they use in hospitals when you break your arm. then you can fill it with foam.

done it, works well.
