Carbon Fiber Freediving Fins, Resin Infusion, DIY

[@epicadventure1474]

Thank you for a wonderful video ! what weight carbon fiber cloth did you use ?

[@diyfreediver]

The magic for me is when the carbon fins turn into plastic at 10:28! But all kidding aside, amazing, carbon fins in 24 hours. It would take me 24 years to do everything you did, but it’s cool to see the whole process up close, thank you :)

[@mechanijun]

Haha thank you for watching my video! I forgot to wear the carbon pins when taking video. In fact, I was hesitant whether to use the that footage or not. but I decided to use it because I spent a lot of money (airplane, hotel, drone, etc.) for this video:) thank you!

[@diyfreediver]

@@mechanijun Yes, I see what you mean. Luckily, I think the video flows smoothly. I was just watching your fin movement very carefully because I recently purchased my first carbon fins and I’m not happy with their performance-especially on the surface.

[@mechanijun]

I understand how you feel because carbon fins are expensive. It is easy to make one side of a composite product a glossy side, but difficult to make a double sided glossy side. If your fin surface are poor, there may be a problem with the fin mold. Normally, fins are made in three main patterns. Straight pattern (the way I made it) V pattern X pattern. It is better to choose one of the two (X,V) as it is more natural when the fins are bent. but these are expensive due to carbon fiber consumption.

[@diyfreediver]

@@mechanijun Thank you for the helpful information. What is your opinion regarding fiberglass compared to carbon fiber? I noticed that Molchanov uses fiberglass for their best mono fin and carbon for their best bi-fins.

[@mechanijun]

no problem! The advantages of carbon fiber is especially weight and strength, except for price. The difference is little, also we're not pro divers, so I think fiberglass is good enough. But people are always looking for something better :)

Dios te bendiga mucho me encantó tu video te veo desde República Dominicana San Pedro de macoris quisiera saber en cuanto me haría un par de esas

[@AK-47-z1c]

Well done, thank you for this useful topic

[@TAGspearfishing]

Great video! Do you use a special resin so that they can endure thousands of bends without cracking? Also, did you just guess at how many layers of carbon?

[@rogamingz206]

whats the orange thing called along the sides of the fins? and what did you use for stickers? and how did you seal the slope of the jointing glass?

[@AtasubSpearfishing]

epoxy resin or polyester? rigid or flexible? i from brazil

[@aidilzikri5789]

Can we use resin hardener only rather than resin infusion sir? Can u explain tu us? Thank you sir!

[@myotiswii]

Was coming here to maybe make them myself. Not happening whatsoever, but still cool to know how the fins that I could theoretically afford but dont want to spend so much money on are made.

[@slplktr]

Wow. That looks really good! Although I almost had a stroke when you used your brand new fins on shallow rocky water. :D

[@mechanijun]

haha thank you so much :D

[@kaloplorossevedoukas254]

very nice video brother, could you tell me what the last two green sails are and why you wear them? thank you good evening from greece

[@mechanijun]

these are water rails and prevents water from spreading out of the fins.

[@muhammadgomaa5768]

Thanks for sharing this experiment really appreciated Where did you get those silicone Rails? The orange thing in the sides?

[@mechanijun]

thank you for watching my video. I got those from a Korean internet store

[@AK-47-z1c]

Can you help me send me the full names of the equipment and tools used in the video?

[@TheVlood]

Hi! Whats the sticker you use for naming?

[@max.m4Q]

what is the actual material name last liquid used ：the “top coat”？

[@mechanijun]

Yes

[@ConvenMaster]

Incredible bro..

[@mechanijun]

Thank you

[@kizzjd9578]

Should use angled tapered layers of uni instead

[@mr2ferrari]

Clever design!! Great work 👍

[@mechanijun]

Thank you sir 👍

[@phillipdeblanche9083]

Excellent!!!

[@GHOSTspearfishing]

Did you use laminating epoxy or vynylester resin? What do you recommend?😊

[@mechanijun]

I used epoxy resin for theses fins

[@cortneyschwartz6523]

Awesome video!! You rock! Have you categorized the flexibility of the fins(high flexibility vs low or medium) based upon the length of the 4 inner core sheets? What lengths of sheets did you use? Can you provide some detail about that ? thanks again.

[@mechanijun]

If increase the distance between layers, it becomes shoft, if narrow, becoms hard. Length is 800mm

[@ahmedal-amrain5274]

What are the dimensions of the fins length and width, and the angle at the foot

[@diegosabba3936]

sorry can you give me a name of top coat to buy it?

[@ryle9045]

So satisfying to watch.. was the top coat resin as well?

[@mechanijun]

Yes

[@PinkFreediving]

혹시 얇은 카본천을 이용해서 더 많은 적층을 쌓을수도 있나요? 그렇게 해서 내구성이나 탄력이 더 강해진다든지

[@mechanijun]

안녕하세요 얇은 카본 원단으로 만드는게 장점이 더 많을 것 같습니다. 얇은 원단으로 적층의 단계를 더 많이둔다면 핀이 휠때 두꺼운 원단보다 핀 곡선이 자연스러울 것이고 물속에서 추진력 발생시 좋은영향을 미칠것으로 생각됩니다

[@salomtabai]

hi sir, what kind of clothing did you use? how thick? and what is the number of wet system resin did you use?

[@baghovicizet2957]

sorry, where do you buy the side grip (orange) from?

Hey really good video and work 2 questions : what are the dimension of the blade to fit perfectly with the foot pocket ? which spar did you use to fit with your foot pocket ? you use a leaderfin foot pocket right ? thanks a lot

[@mechanijun]

Yes, I use a leaderfin foot pocket so dimensions are the same as a leaderfin blade

[@nicolasolive3849]

@@mechanijun can you send me the dimension ? I want to try to do the same as you did but i am beginner in composite Which water rail did you use to be compatible with the foot pocket ?
