- I make surfboard fins for a living and field a lot of inquiries about construction and processes. As I just finished single fin number 1,000, I felt it was time to document my procedures and share it. I believe strongly in progress through shared knowledge and hope this video may help someone make their own fins, or perhaps see some way I can improve my own process. Thanks for watching!

Thanks for sharing your knowledge Korey. Best fin panel layup and foiling tutorial by a long way. Would love to see how you do your twin fin foils and do the tabs particularly for Futures boxes. Cheers mate, can’t wait to see your next upload.
Amazing tutorial dude! I’ve been making my own fins for a while now and learned so many great tricks from this! Thank you for sharing!
Stoked to hear that! That’s all I can hope for. Thank you for checking it out.
Amazing REFERENCE, not only a tutorial... Good work
I've been making fins since I was 16 years old . It must have been pretty hard with no power tools at all . Enjoyed your video to advance my skills . From Santa Cruz , Ca . Thanks
Great video, lots of good information. When I lay up thick panels of one colour I either vacuum them to the flat surface or now use resin infusion. It means one can do the whole laminate in one go with low exotherm resins. OK, one colour is a bit boring, yours is much more artistic! Your foiling process is terrific, I learnt a lot. Cheers
Hell Yeah, a cartographer girl here :D
thx fort the video, wonderful knowledge you shared 🤙
Beautiful work Korey. Plus a really well put together video that includes a ton of hows, whats and whys that make the physics of that build so effective.
Thank you!
Amazing craftsmanship.. It is a functioning work of art... New subscriber.
What a great tutorial! I have always wanted to make a fin for my log thanks for the cool tips and tricks!🤙🤙
Watched this a few times it’s awesome thank you
such an awesome video, thank you for sharing,. definitely have a newfound appreciation for all my fins.
Thank you for the lesson! This is a precious video for anyone who wants to try to make his own fins. Exhaustive, to say the least.
It can be daunting, but rewarding. You just have to want it!
I used to do gel and silk nails and it’s interesting how similar these processes are. The filing process in particular is what builds the strength of a nail enhancement, and if I’m understanding this correctly, the filing process is what builds power/steering ability into a fin?
I’m in TN note and learning to refinish my old epoxy surfboard. Maybe I’ll try to make my own replacement fins next so that when I make it out to the Atlantic again, I can welcome my board back home.
Awesome video. Thank you for sharing your knowledge, and really, your art! Beautiful work.
Thank you so much for this - I've been looking at making fins for a little while now and this is without a doubt the most comprehensive tutorial anyone has done! Question for you re: finishing:
1. What are you using for paint to stamp the board/sign? Posca/Acrylic?
2. What finish spray are you using... concrete sealer like with boards?
Thanks again for this amazing resource.
Thanks for sharing your knowledge 🤙🏾.
Thanks for sharing your knowledge!!! Excellent video.
Amazing, thanks for letting us into your process and mind on these things. New found respect for this craft.
Great video and nice Jive Lifter in the background.
I could get rid of them all but that one sometimes.
thanks for sharing, the fin with the orange edge is very cool
I am intrigued and thanks for this very informative vid. I am now looking forward to getting started and making some sick fins.
Excellent video mate, and beautiful fins 🤙
Awesome stuff Korey!! Thanks for sharing this!!
Best in class dude - thanks for sharing and well done.
Hey, thank you!
Bro the way the red glows 😍
Nice work!🤟🏼
That was informative and fun, I have a new found appreciation for your craft. The fin looks amazing! Thanks for sharing.
Thank you!
Loved it. Thanks for sharing what you know
Hermoso trabajo! Gracias por mostrarnos tu arte y maestría. Un abrazo desde Lima-Perú.
Great video! More pls 🙏
Amazing video. Thanks so much for sharing. Absolute works of art. Keep it up!
Thank you greatly!
Wonderful, worth watching. Exquisite work in every detail. Thank you, I learned from you, and this is an honor for me, my teacher
it's so nice, good inspiration! Thnx!
This is so sick! Beautiful fin. Thanks for the helpful vid. You gonna make more vids?
It’s only a matter of time!
@@hydrophilesurfcraft Looking forward to them!
If you didn't know ? now ya know !!!!! Fantastic, thank you
Man, I wish I would have found this sooner. Thanks for sharing, wish I could have joined the raffle! :) 🏄🏼♂️
Wow! It's awesome! I really appreciate it you sharing your knowledge and your beautiful work! Thanks man and keep going!
this was a nice video, thanks.
My God ! Solid fiberglass. I use two. 0.020 FR4 sheets and a 3/16ths fiberglass rod to make the curve foil shape. I cut the FR4 sheet to shape so i have the fin shape to start with. I bond the rod between the two sheets, then bond the sheet edges. Then start glassing onto the correctly curved blank. Not much sanding to do. And it it much lighter. WOW. Well i will need to post some photos on my channel. ❤❤
Ha, yes. Fins like this have been the foundation of surfboard fins for decades. Yours sound interesting!
@@hydrophilesurfcraft Best information at tech ingredients Utube channel the guy is way cool, the electric catamaran project. Perfect foils with minimum effort.
Anyone ever tried using a Cricut machine with rolling blade to cut out layers of glass in a rough shape of the fin before laying up? ... I really liked your explanation of the blunt leading edge and maintaining laminar flow in a bottom turn, btw.
Sam of finflex has cut layers rough to shape and laminated them to reduce waste, etc. He’s also recently been laying up a couple layers of glass into a thin sheet, then cutting those layer by layer and then gluing those “veneers” together to create a similar result. Thanks for digging in!
Awesome tutorial Korey! Thank you.
Thanks, Eric!
Great vidéo ! Can i ask you how to make futures fins ? Cause the cant angle in the fins is so hard to do...
I definitely won’t be able to explain this process in a comment. I *might* do a video about this in the future, but I am not planning one at this time.
Thanks for sharing Korey, learned a lot!
Thx for this video man! Nicely made, lots of tips and tricks! It helped me at some points where I wasn’t sure if my process is alright etc! And it has another value. Now I can show this to customers as people usualy don’t what amount of work/skills/experiences etc is behind fins making / boards building. Cheers Milos / Apatyka surfboards
Thank you, Miloš!
Btw as you mentioned using jigsaw blades for cutting metal, they really do not work good on fibreglass panel. I tried it once and they got dull so fast… since I did a bit o research I started to use a carbid blades, bimetal blades and some others made for laminates/fibreglass.. I can check it out later on and write up the info here, maybe it could be helpfull to other guys trying their luck with jigsaw :)) I watch the video for the second time already and really enjoying it haha. Thx once again!
They definitely dull quickly! I don’t use one much, so I have not experimented with other blades, but that makes sense since I use a carbide bandsaw blade.
This is great!!! You’re from New England? I’m from MA. Love to support the locals
Thank you, yes!
Hi, love the video, the best one iv'e seen.......I want to add a signature to my fins when made, do you need to seal the posca pen after with something? and what paint did you use for the stamp?
You are at the top of your game.......definitely a master of your craft.......well done...... very professional........I do have 1 question.....where did you source your articulating clamp from......been trying to find one for woodworking projects......thx
It’s a multi-angle vise by Stanley.
so good Korey, thanks man!
thanks for sharing!! awesome work man..
Thanks for watching!
that was a great video. Thank you.
Great work .... Thank you.
Hell yeah!
this was awsome! mahalo braddah Korey! i got a couple questions. what did you use for the spray finish and can you use poly instead of epoxy?
I use Montana gold varnish, and yes, poly is a much more common resin for fins than epoxy.
id love one for my Log...
Thank you for your awesome video! Just what I needed! I have some scraps of fiberglass laying around that I would like to use for my first DIY fins. Some are 4oz, some 6oz though (approximately), so using the same number of layers as you, would not sum up to the same thickness in total. So I guess my question is: how thick should the stack of cloths be, pre laminated?
Thanks in advance, and keep making them fine fins!
If you have calipers(get some if not and you’re making fins) you can measure the thickness of your cloth and use that number to calculate how many layers it will take to reach 9-9.5mm or so. It’s always better to ensure your panel is thicker than the box so you are able to shape it to fit.
6oz single fin panels are about 42-44 layers, 4oz panels are at least 60 layers. You can calculate what you’d need judging by those numbers as well. Good luck!
@@hydrophilesurfcraft Thanks man! Another question: if I would not use the twe colored lay up, like u did, would I still do the lamination in three go's? The obvious answer would be 'yes', since having to take into account the curing time of the resin. But, you know... asking for a friend ;)
ps: so how do I win this awesome fin? :)
By the way: since the sawblade on your bandsaw tends to dull very quickly, mayby you could skip sawing the edges of your plate, before cutting the actual fins (assuming that your plate is flat, even at the edges). Just a little something that caught my attention. Cheers!
If I’m doing a solid or uncolored layup, I will lay it all up in one session, with multiple mixes. Generally I won’t mix more than about 40-50oz of slow cure epoxy at once at the very most. If I’m doing a full sized 30”x30” panel, it requires around 4 pots of epoxy that size. You just need to consider your own comfortability and working time with your resin before doing a big mix and having it go off on you before you’re done. Once the glass is laid up and the resin is distributed over a larger surface area, there is less of a risk of exotherm than there was while it was in the bucket.
This fin has been given away already via Instagram. Any further giveaways will also be done there, so please follow me if you haven’t. ✌️
@@hydrophilesurfcraft Thanks again, sir!
Thanks this is awesome ! Perfect lesson 🙏🏼
Thank you, glad it was helpful!
Great vid and info! Can you recommend where we can get template for fins?
@@kellydoran7039 I mean, there’s tons of images of fins online. I make all of my own templates and use Illustrator to scale and modify them.
super!! real supirior hand!! thank you
Hi.nice to meet you, my name is Tomo.
Thanks for sharing your amazing knowledge and technic.
I'm making fin at my friend's urfshops.
So I have question.
Can you tell me about fin's base sanding machine, I really want that one.
I’m happy to share! I use a table router and 1” spoilboard bit to bring the base close to thickness, then take it the rest of the way with a sanding block I made myself.
@@hydrophilesurfcraft
thanks for reply regend!!!
table router is made yourself too?
I want copy your sanding block!!!
@@北村友宏 no, the table router is made by Bosch
oh!I got it!
thank a lot really🙏
I'm check it out!
Sick video. I’ve watched this about a thousand times. My question how did you mark off the centerline of the fin?
Thanks! I use a 3d printed tool I’ve been working on with a friend of mine. I’ll have them intermittently available. Here’s a post about them:

Awesome video, how do I purchase a fin off you?
I sell direct through my website when I have stock available. Some are available now via Pilgrim and Surf Exchange Co.

Thanks so much for inspiring budding fins makers!... You're a legend. What do you use to print you logo and details on the fin? And what do you use for the final spray coat?
Appreciate the long video. I'm not a cartographer, but foiling fins is the best use of my physical geography degree I can think of! Haha
I use a laser cut rubber stamp bought online with white staz-on permanent ink and white Posca pens. The spray I use is Montana gold varnish.
Thank you for sharing your knowledge. I really appreciate it.
I tried to make the layered panel 2 times but either I failed for piling up the layer.
Could I ask you for advice?
First time, I used Entropy CLR resin with CLX and while I was layering it up it started hardening so It was clear that I did choose wrong hardener. CLX is extra fast hardener.
Then I tried again, with West system 105 + 207. According to the mechanical sheets it said usable time is 100 to 120 mins but after 20 or 25 mins it started hardening so I couldn't make it again.
Could you let me know which resin and hardener do you use?!
Should I use Entropy CLR resin + Slow hardener or maybe CCR Casting resin?
Thank you
Never use casting resin. I use entropy CLR and CLS slow cure hardener. I never mix more than 40-50 ounces at once, despite what it may say on the epoxy’s spec sheet, it will go off quicker in a container where the volume is concentrated, especially with CLX. Epoxy takes time, and it is worth it to give yourself that room for error when starting and use slow cure hardener.
@@hydrophilesurfcraft Thank you for reply! it helps a lot to me
I mixed it just 1L like 40oz but while I was working it went hardened so fast;;
I rekon I need at least 1 hour for working
Could I ask how long it takes for layering up in your side?
By the way, I will try CLR with slow hardener!! I will keep you posted!
Thank you so much
@@김기훈-b4p9o 40oz, but with CLX, it will go off much quicker than CLS. If I am doing a full 30”x30” fin panel, I will mix in batches of about 40-50oz of resin, which will get me through about 7-9 layers of cloth and take about 20-25 minutes. Anything beyond that, and you are mixing too much epoxy, in my humble opinion.
cheers mate, learnt so much, just wondering what are the pros of using epoxy instead of poly resin? will it have the same flex? Thanks!
The flex characteristics are definitely different. Epoxy has a more plastic flex, in a good way I feel. I use Entropy especially for it’s lessened ecological impacts and no odor. It allows me to do this from home without infiltrating my house with fumes.
@@hydrophilesurfcraft Nice, thanks for the reply, please post more tutorial videos. cheers
good vid. What is the ink and stamp you use for your Logo?
Stamp is ordered online. Plenty of places will make them for you. Ink is permanent white ink by Staz-on
Thanks man
Thank you so much for this video!
If I was planning on making the same size panel with 6oz instead, would I have the same amount of epoxy?
I would not let my volume of epoxy dictate what you’re doing. 6oz cloth will require less resin per layer, but your panel will require more layers to be appropriately thick. Likely 40-44
Got it, Thank you!
Do you recommend a specific brand of epoxy?
I have the most experience and success with Entropy CLR. It is a worthy investment and they have great resources and guides on their website.
Ótimo dia, Parabéns pelo trabalho, também amo surfar, gostaria com muita humildade e gratidão de aprender a fazer,boas ondas aloha!
wow !!!
Sorry if this is a repeated question but what’s the spray finish you use? Do you need that for a fiberglass fin or is it more to protect your stamp and labeling?
I’m not satisfied with what I have been using, but it’s a spray varnish. It is totally unnecessary, a glass and resin fin needs no sealant, but this step brightens the colors a bit, which is sometimes nice.
That said, the finish from the product I use has been great, but aerosol cans are wasteful and an added environmental problem I don’t need to add to my process.
and down side to using Poly resin? Besides working time?
What is the spray you use at the end please? And any chance that writing will rub/break off
It’s a spray varnish I’m not sticking with, so I won’t bother divulging what it is. I’d recommend something made for bonding to plastics. The stamp and writing are done with permanent ink, some last longer than others. Depends on how the fins are stored and treated.
@@hydrophilesurfcraft thank you so much for the reply :)
Do you make anything with the offcuts of fiberglass from when you cut the fin from the template?
Some, yes.
@@hydrophilesurfcraftreally cool video bro , I'm an hour thorough and excited to try my own
Best of luck!
Would there be any reason to not make one with poly resin?
Most people do. I started working with Entropy because it doesn’t inundate my home with toxic fumes. Now, I prefer the flex, strength, and memory of an epoxy fin. Skis and snowboards are made with epoxy for a reason.
Can you use poliéster resin rather than epoxy?
Most people do
Great video but this method produce more dangerous dust then 3d printing with fiberglass lamination, or clear 3d printing.
A fair perspective, however, so far as I’m aware, there is no one producing fins that way, let alone an individual looking to create their own fins in a home workshop. This craft is an art form both sculpturally and aesthetically as well. A massive and costly glass fiber printing device is just not financially or creatively feasible at my scale, let alone someone smaller.
I misread this initially. There is some use for 3D printing and laminating, if you are capable of getting the lamination to bond with the fiber coating and withstand the flex needed to create a fin as functional as a solid glass fin. Additionally, the reparability and durability of a solid glass fin is vastly superior to a printed core fin, be it impact, flexing to a point of delamination, etc. Home 3D printing is certainly more achievable these days to a hobbyist, but it does also eliminate the sculptural and much of the other aesthetic desires and benefits of glass fiber construction.
@@hydrophilesurfcraft I'm concerned about the significant amount of fine dust generated by grinding fiberglass. While you might wear a mask, this hazardous dust contaminates the surrounding environment, posing a serious health risk to those exposed, especially children like your daughter who play outdoors. Fiberglass particles can become permanently lodged in the lungs. A more affordable and safer alternative would be to create large, rigid fins using a 3D printer. For as little as $100, you could print several parts and then reinforce them with a few layers of fiberglass. I'ts less dangerous then your method. I produce foldable and river fins for paddleboard from 7cm to 28cm at height
@@DigitalLee Your concerns are justified, but you’re not proposing a comparable alternative performance-wise, in my humble opinion.
Why don’t you do a final hot coat after sanding?
The fin is sprayed with a varnish to bring out the colors. A hot coat is a decent option, but easy to burn through, changes the geometry of the fin, and flex characteristics.
@@hydrophilesurfcraft good point, very cool to see the process. I recently acquired a 9’0” Eaton bonzer, I don’t know what fun to use in it, any suggestions?
@@bocajred11ACE Elliot sometimes has Eaton style bonzer fins available. That’d be an ideal fin for one. Those longer Eaton bonzers rule, I’ve always wanted one.
@@hydrophilesurfcraft sweet I’ll take a look, it’s an interesting board for sure, still haven’t figured it out but have only had it out a few times, I’m thinking the fun could be the reason. You want to buy it from me lol
@@bocajred11where are you located? 😂
Why the 45 record plug?
I worked at a record store for a decade. Part of who I am. Audiophile > hydrophile.
