fin for surfboard
I am curious. is it possible to create surfboard fin?
Anybody has done it?
hello! yes you can make a mould for surf and windsurfing fins!
I am planing to mill a small fin key ring mould to night
the same way but bigger scale is the normal fin
the only problems is going to be the bubbles and what type of plastic is more suitable for the fins.. you will need something hard and strong for the windsurfing about the surfing i dont know:)
It looks great!
How did it goes?
I want to set-up a workshop in Sorake, Nias (famous surfing spot).
Making fin, next to other plastic product, seems to be a great idea.
Technical speaking, I am a layman. But I have groups of Indonesian army on my side 🙂 @ramdhan2805 and perhaps they can learn from you.
ps: Thank you @dbougas
Yes it’s possible to make a surf fin from recycled plastic. I have done some experiments with milk bottles HDPE which were strong and seem like a good idea . I have yet to test them in the surf… coming soon.. A lot of modern fins now have carbon fibre embedded for strengthening which can be good for strength but are very tight on the wave. There are a lot of surfers who still prefer simple plastic fins (iv heard including 13 times world champ Kelly Slater). They are preferred for the flex and a little bit of movement that plastic has which aids manoeuvrability on the wave. There can be a lack of drive because of the flex but that can be subjective. the famous surf fin brand has made plastic fins and they were very successful so I think it needs exploration with recycled materials as it’s all conjecture until we try..🤙
I’m starting to build the shreder, and the other machines… it will problably take this month to finish all of them.
I’ll send the updates as soon as they come up..
I have ridden a set of plastic FCS. Definitely not carbon fibre. They were good! Yes there is talk of less drive but carbon fibre gives drive but at the expense of manoeuvrability. It’s your preference. I like to carve 😉
I have also recently seen these people who are making fins in Bali/australasia and doing good work! I see they say they are re-inforced with fibreglass. I have not tried them out.. Has anyone tried these?
We love this POST, we are in the same process of manufacturing the surf fins, we are doing some tests and testing economic molds, these pieces that we did with a red silicone mold for high temperatures (up to 300 ° C), still remain a little deformed and we are now looking to make some molds in aluminum as in the videos of preciosu plastic !!!
These tests are in PP, and PEHD, at 250 ° C in the injection machine.
When we have more progress, we will be showing you photos.
In addition to this, we want to implement it for the project we are working in the Colombian Pacific, because many times with children who surf, have many difficulties because of the surf fins, since they are very expensive in Colombia and are not easy.
So we keep working !!
Greetings from Colombia !! 🤙🤙🤙
I forgot to upload picture about the little fin that i tried days ago..
here is the key ring fin for advertising purpose for my windsurf center (i will go to engrave the link on top to the mold at a laser machine)
the photo does not appear i try again!
Hello! i didnt try if the keys is floating i think no..
i will go to cnc to engrave the logo and and i will upload the final result!
Awesome work guys! Im a surfer and creating a plastic recycling workshop in the dunes of The Hague. Im focussing on simple creations that can be made and used by highschool kids and not (yet) really on surffins but I’m an adaptive surfer (i surf with a prosthetic leg) and can participate at the World adaptive surf championship in California end this year so it would be awesome to do this with recycled fins and use all the media attention to promote plastic recycling!
Please let me know if it worked out for you to make recycled fins. Can i follow you online somehow?
All the best!
sorry for this late reply, im busy moving to a bigger workspace and will start posting more pictures soon.
hahah yeah a prosthetic leg made off recycled plastic that would be insane! I will definitely keep it in mind. For arm prosthetics thats not even impossible, i think that can be done by 3D printing but for legs its more complicated cause it has to be strong and firm. My foot though.. could may be made by injection moulding. But then i would spread microplastics in the sand at the beach when i walk barefoot haha, maybe with a coating. Somebody familiar with this?!xD
