Hi folks,

This information is probably in the forum somewhere, but there are an overwhelming number of subjects, and I wanted to show what I was up to, so I thought I'd just ask anew.

This is something I've been working on. I've noticed that the basic choices of a mertail are either a lycra tail in the $125 range or a full on silicone tail in the $3000 range--and not a whole lot in between. For someone like me, a backyard/swimming pool mermaid who just wants a pretty tail to swim around in and has no interest in performing or being a professional mermaid, a silicone is WAY out of my price range. BUT, as a costumer, I wasn't loving the simple spandex designs I was finding. I wanted to see if I could come up with a sort of hybrid that merged the two.

I made a lycra koi tail that was meant to work with the monofin partially exposed. Since I was doing fluttery fins anyway, the monofin doesn't show. I love the look, but it's not much for swimming very quickly--too much drag. However, it's awesome for fluttering around in a pool at fairy and costume conventions. After I made that one, I wondered if I could use the same method to make the tail, but remove all the fabric and sculpt a pretty silicone fluke over a monofin so that it would mimic the look of a full silicone tail for a fraction of the price.

Here's where I am as of today. The first photo is my lycra koi tail. The next two are my unpainted monofin prototype for swim-testing, created on a Suntail monofin. So far I'm delighted with how it's coming along. It looks good and there were very few issues with the molding process. Finally, here's my question. Since I am only doing the monofin and not a whole tail, it's imperative that I have an adhesive that will keep it firmly adhered to the fin. I used a silicone caulk, but it's really not bonding to the sculpted part. Has anyone found something that really gets the silicone to permanently glom onto a monofin? Any advice would be greatly appreciated.

Silicone sticks to almost nothing, except silicone. You have to attach it mechanically. The method used by others:

Get self adhesive Velcro. You use just the fuzzy side. Stick that to the monofin. Cast the silicone on top of the Velcro. The silicone soaks into the fuzzy fabric, making a mechanical connection. You can also take a pre-made silicone part, put some more silicone on it, and squish it down on the velcro.

it's a bit of a trade secret it seems. People have lots of ideas but in my experience few actually work in practice. It seems when people actually find the best way, they are tight lipped ;)

Have you tried E6000?

E600 won't work in this instance, it doesn't stick to silicone.

Generally, a well-encapsulated fin (with drainage channels) will be just fine with no ballooning. The velcro idea is good, too, but I'd fortify the sticky back of the velcro with something beefier.

I love what you did with the Sun Tail monofin. Its so cool looking!

Man silicone is stubborn! Why its not friends with other materials??

I can see why tail makers keep certain things a secret.

Oh man that fluke is gorgeous! If it works and you are ever up for a commission, I would totally get one of these!

I've been planning to do something similar but with shelf liner - basically, I just want to make a clear fin (I have a Hydra, so my monofin is already clear) with a fabric tail. But I was planning to basically just make a pocket that the monofin will go into. Not sure if that would work well enough for your plans?

I have been wanting a clear koi fish fluke as well, unfortunately my monofin is a bright yellow wave. I did get shelf liner and make a pocket but the stitching really wants to come apart. The only fully clear monofin I know of is the one in Pearlie's video a while back. I had a plan for fins/a fluke with zip ties, not to propel the tail but for the fishy look.

I'm definitely hoping to make them to sell eventually. I'm still in the testing phase for now. Once I get something workable, I'll post info in the sales area. I still have to figure out the adhesive and pigmenting, but so far so good!

I just thought of it today...

How bout making the two sides bigger, and sandwich the monofin inside the silicone pieces, using the strap holes. Then you use silicone in the little holes to glue them together. And instead of the neoprene foot pockets, glue on some swim flippers?
