    if you decide to use plaster here is a tip: have a partner and yourself mix up the quantities in separate buckets. eg if you decide you need 4 kg to cover the fluke for the initial mold then get your partner to mix up 2 Kg then both pour together from the one point. this will ensure that you cover the entire mold without having uneven sides. speaking from experience here. NB any unlevel mold can resort in silicone pooling on one side of the mold or even spilling over the edges of the mold. this usually only happens in the thinner spots. ENSURE WHEN MAKING ANY MOLD to create the mold on a LEVEL Surface. you will be looking at a thickness of about 2 to 3cm for the mold to ensure it won't crack upon lifting.

    fluke thickness, ive created mine to be around 3cm thick at the top once the halves are put together and midway down is about 1 to 1.5cm the bottom is left around 3mm. you won't most of the thickness up the top and centre in order to act like a monofin. NB something to think about, the thickness you do your fluke needs to be taken into account in order for your extension to be able to take the weight of the fuke.

    what are you casting your fluke in? silicone or silicone Rubber?

    your fluke looks good. just a reminder your fluke needs to be symmetrical on both sides in order to add up.

    Can someone please get me back to the ocean before I suffocate... I need the water......

    Thanks alot Moonchild , actually im not making a skeleton like on the original H2Ķ tails in using lexan as the monofin.

    Thanks for the tips on mold making I didn't know all that. As for the thickness of the fluke I've made it just as you said except for the size and stuff. The lexan available to me at Homedepot is not stiff enough to me so i made the fluke like the upgraded Mako Mermaids tails the way the fluke acts like a monofin without one inside it I need that. As for materials I've been thinking about using a Urethane thats a bit harder than the Dragon skin silicone because of my obsession with my fluke not beying too flowy dont get me wrong I don't want a stiff fluke but it cant be flowy like Ariels fluke LOL...

    I thought about urethane but i was thinking that once the halves are bought together it would be too stiff. Im casting my fluke in rubber as its more denser than silicone.

    Can someone please get me back to the ocean before I suffocate... I need the water......

    What kind of rubber ? I'm going with the Silicone for the fluke because I have more experience with it. Plus the extension also haves or is a Monofin, I'm also sculpting the fluke thick.

    Ive chosen to do my fluke in rubber becuase most silicones are softer in that department. its a smooth on rubber but i can't remember its name. you can dye the rubber to any colour and from what i can remember it has good tear strength and wearing resistance. of course i will buy a trial and test before casting my fluke. most silicones ive found don't go past 30 shore A im looking for something the the 40 to 50 shore A range.

    Can someone please get me back to the ocean before I suffocate... I need the water......

    Whisper, it doesn't hurt to watch the series. I found them entertaining. In my personal opinion they weren't as great as H20, but for being able to watch Mermaids and stuff it filled the gap. The first episode COMPLETELY captures what it feels like to swim for hours and then try to legs. My guppies and I laughed SO HARD that Cyan had a gummy worm go up his nose and he had to blow it out. And the new approach they had to when a half-mermaid gets a cold was tickling.
    For me it was good to fill the void left by H20 and also look at all the new FX I may be able to reproduce at home. I am not a fan of the new tails, and definately NOT the tops, but the thicker flukes give a nice smack and i wouldn't be worried about fishing hooks.
    When you're caught and find yourself tossed back,
    take advantage of the motion, and catch the next wave!

    I was looking at the urethane sold by smoothon so seance urethane is harder then silicone is the shore 30 or 40 good for my fluke?

    if your looking at a stiff fluke then 50 or 60 would be better.

    have a look at the scale of shore A 50 to 60 is medium soft to medium hard. if in doubt go the 60, if you want flexibility or a flowy tail i would go 40. deciding on these products is hard because you can't feel the product before you buy so you just have to go off the information.

    P.S. it broke while I stupidly tried to change locations by lifting it without beying able to support the whole thing.

    you could sculpt it on some card or a piece of board to avoid it from breaking.

    do you know how you're going to add your fluke to your extension?

    Glue some glad wrap over the cardboard this way your plasticine won't stick to it.

    Get some of this: http://www.homedepot.com/p/24-in-x-3...2436/202090128

    I sculpt my flukes on it...there's a 72" option as well, I get those and cut them in half. I tape mine to a piece of pegboard, but any lightweight plywood works, and resin doesn't stick to it.

    I like the first one It doesn't look like Zac's fluke, it's your own design

    I guess you misunderstood me sorry thats my fault. I meant my old design is similar to Zac's fluke so I drew some but still undecided...

    Here is my old fluke design sketch the one that's similar to Zac's:Name:  20160801_085146-1280x720.jpg
