Glassing Surfboard - Fused Carbon Stringer

Glassing a Stringerless Surfboard whit UltraWhite Epoxy Resin Kinetix 110.
I used a Carbon Stringer Fused 30mm for Top and Bottom Lamination.
Start to Finish Lamination process.

I’ve been shaping since 2017, but I would not declare my self as an expert.
Everytime I put a surfboard I shaped into the water the exlamation it is always the same "F**k Yeah GALLEGGIA" (it floats).-

Board looks good but you can shave off lots of time if you did the futures box route out and set them before you did the carbon . Not only does it save tons of time its essentially a lot stronger as the boxes should be capped with the same glass that the board is glassed with plus extra patches - thats the real meaninb of fused . if you are worried about air use a blade and pop the bubbles near curetime. After the flip amd before the hotcoat open up the boxes with a grinder , keep moving around so they dont soften the glass ..this exposes any air bubbles that get opened up during the pre sand. Hope you found this helpful grasshopper!

[@cerritosway]

Thanks Peter. I appreciate It. I usually route boxes before laminating bottom, this time i got confused by carbon stringer application and i went straight to lam. I Will keep your message as guidance.

Grazie MyFriedFriend! 😎

[@seanmcgann6643]

That single carbon strip on a stringer less board adds unnecessary stress points. You should wrap the rails also. Thats sharp edge on the carbon beads up with resin and is a point where stress will crack it easier

[@cerritosway]

I will take note, many Thanks!

[@lirider3932]

Nice shape and those rails...

very good work and i really like it

[@cerritosway]

Appreciate It man!

[@benskai2475akurfishing]

@@cerritosway thank you brother for all the knowledge

[@slavickskromul281]

Nice work bro... I see you use like 1lb or 1.5lbs foam like insulation material, and then you fill it up with micro balloons and gabosil(silica)... that would give that foam, a nice white look, and add alot of strength, plus foam with big beads obsorb water alot easier.... but it cant do it... can it? Lol not if you mix up the filler from epoxy.... so in conclusion... where I'm from you can get that type of foam for less then 20$ 4x8 feet 2 inch thick, slice that in half you got 2×8x2inches... you basically got a blank for 25$ + work... that's awesome... 1lb foam floats atleast 40% more then pre-made EPS blanks ... so you get a snow white ridged 1lb pound surfboard.... That is something like Firewire "HELIUM" construction.... Super smart bro! Nice work! I've tried 1lb foam before but I was using patch and paint spackle... it was coming out weak... so I had over glass it... and then it was too heavy loo. Keep.doing what you doing man. Cheers.

[@cerritosway]

Yhea you are right, Is 1.5lb, with small beads. Buy still absorb Lots of water if you get a Ding and keep surfing It. I used microballon plus epoxy, mostly becouse give me a Better lamination with less air Bubbles. Now i am trying a preshape super fused EPS, they says suck less water, we Will see After the test. Thanks for your support, means a lot to me.

[@dacat8171]

I really enjoy watching you 👍🏾

[@cerritosway]

Thank you so much 🤗

[@jamesplaum1927]

hey why would you seal the board with epoxy/microbaloons instead of spakle or something like that? epoxy is way heavier and harder to sand?

[@cerritosway]

I tried both, when I was using cut block eps. Once I used spakle I had a delam issue, so I stick to epoxy and microballon. For a short I usually stay around 3kg max. But now using superfused molded eps I am not sealing anymore.

[@manuelmarques5669]

Nice! the heat gun in the hotcoat is for bubles to rise in epoxy?

[@cerritosway]

Yes It Is. Aldo becouse was a humid day

[@Mach1-9538]

What do you use for the decals i lay? I know its a bit late

[@cerritosway]

What do you mean? What I use for logos?

[@confdenhaag]

more tail rocker plz !

[@cerritosway]

I know, unfortunately we are mediterranean fishes! I usually go for 5-6 cm tail rocker.

[@anon8730]

How come your're microballoon residue is so white? I did it but my board hasnt gotten any whiter it kept kinda transparent. And when i add more microballoon it gets to thick?

[@cerritosway]

Footage and light enanche the brightness. But I use Kinetix 110. The R110 uses a custom designed UV Optical brighter and create superior whiteness and the highest levels of UV stability.

[@PoltergeistWZ]

Hi! It's EPS or XPS? What density of foam did you use for this board?

[@cerritosway]

Sorry for late reply, But I took a period of youtube! EPS not superfused.

[@JorgeRodriguez-np3jk]

Muy bueno sencillo rápido espectacular

[@cerritosway]

Muchas Gracias Jorge

[@xisotopex]

do you both sides with the microballoons? you flip it while it is still tacky? never mind!

[@cerritosway]

Ei. Sorry for late rep. Yes I do both side. I wait to flip it. Or insted I tried laminate bottom while is still tacky. then flip it, seal it wait 1h and laminate top.

[@xisotopex]

@@cerritosway are the microballoons necessary? my local pro shaper uses exclusively eps foam and epoxy resin and does not use the microballoons, and his boards are amazing, extremely light and never lose that lively feeling.

[@fra_ce]

@@xisotopex not necessary all. The are different Eps foam. If your local shaper use Eps super fused, the beads Will be tight and wont suck much resin. Instead when you use a block cut eps there Is more space between beads, so It Will suck much resin in. You can use epoxy+microballon, someone use only resin, others use no sealing and just put extra resin into the Lam process.

[@joeblow1942]

Nice! Thank you. If you are spraying acrylic paint on the foam, would you seal (epoxy + micro balloons) the foam before spraying the paint or after?

[@cerritosway]

I never try to spray Paint on the foam. EPS would melt if you spray Paint directly

[@joeblow1942]

@@cerritosway I said acrylic. Acrylic is water based and won’t harm eps.

[@cerritosway]

@@joeblow1942 Oh ok, I misunderstood, scusami! I think I would first seal the blank and then spraypaint, becouse epoxy+microballoons create a kind of white layer, so it will ruin the color.

[@joeblow1942]

@@cerritosway Thanks! I took my board to a glasser last June and he did nothing so I just got it back and I’ll glass it myself. Problem is, he sprayed it yellow without sealing it first. (1.5 lb eps.) Question: Since he already sprayed it yellow, should I seal it with straight epoxy (with no microballons) or forget sealing and just start laminating? What would you do?

[@fra_ce]

@@joeblow1942 whitout having a look a It Is difficult to Say. But if you feel that It Needs a sealing you can do It with only Epoxy. Try not to squeege with to Much pressure otherwise some beads can pop off. Also when resin dry, you should give a little Sand, try to be gentle to not scratch the Paint.

[@robbieevans6536]

I don't understand why they don't make blanks with an actual carbon stringer instead of wood.

[@cerritosway]

It could be and idea.

[@Logan-gi2lm]

Because it would be a bitch to shape cuz of how hard carbon is

[@CarsonWilcox08]

So if I’m doing carbon strips on the tail is it just for looks or does it do something, if so do they have to go a certain way?

[@cerritosway]

Let's say it will reduce foot dent and give a bit more strenght. It is still carbon fiber, so it will give more strenght to sensible part such as tail

[@surfershaper]

Lay up a test swatch on a piece of scrap foam and that will be your evidence to what strength it offers

[@dacat8171]

For looks only. It is not a stringer and therefore foot dents will only be a matter of time. ☝🏿🧐

[@Mullersemacesso]

👏👏👏

[@Monstamonkey]

Very nice! Good to see the application of the carbon stringer in a video too. What are the dimensions of this board Mate? And don't worry about your English, it's actually quite good.

[@cerritosway]

Thanks Mate! It Is 5.9*19.5*2.25.

[@Monstamonkey]

@@cerritosway Thanks for the reply. I'm liking the Kinetix resin too. Watching the video again.

[@GGGinJe]

Very nice job! But realize that these Carbon Stringers, other than looking very cool, provide only an itty-bitty bit of spring characteristics, and add zero to negligible strength to the board.

[@cerritosway]

Thanks B B! Seems to work really well. At least the owner Is satisfied. You are right without a 6-6-4 lam schedule Will It broke within the First session. However i think the carbon stringer give to the board a bit of rebound in Linear Flex.

[@GGGinJe]

@@cerritosway Yes, the "rebound" is what I referred to with the "bit of spring characteristics" comment. I will be looking forward to your next build!

[@cerritosway]

Oh ok.. understood

[@surfershaper]

Glass a piece of carbon with grade A epoxy and see how negligible the strength is. Thanks for the laugh!

[@GGGinJe]

@@surfershaper Negligible strength in the videos applied configuration, comment stands. I won't further respond, so go ahead, bust a gut and have more laughs.

[@MD69BarrelKilla]

What’s the point of a carbon stinger?

[@cerritosway]

You should ask BIG Industry. They say it helps Rebound and Strenght into the board. But I have seen many stringerless Surfboard broke in half.

[@MD69BarrelKilla]

@@cerritosway I wasn’t being sarcastic in any way. Was just honestly curious because it seemed so thin.

[@cerritosway]

@@MD69BarrelKilla sorry It's just me that I am bit skeptic about carbon striger. I use it becouse market use them and It is always carbon fiber so it will add strenght, but I am not so sure about it. Last time time I have seen a thick carbon striger from a notorius brand broken in half, so it deepence most on how you use the board, If you land a big air in a bad feet position or a big close out on the board It will broke the board. Stringerless board need a stronger cloth lamination otherwise is too wick also with a carbon stringer.

[@MD69BarrelKilla]

@@cerritosway yea I agree. If the board is going to break it’s going to break. I can’t see the carbon stringer helping too much.

[@surfershaper]

@@cerritosway I use S-Glass for the extra strength, in addition to the fused carbon for the kinetic recoil

[@SMC4117]

Not sure what’s up with the carbon fiber stringer thing but if it’s for environmental reasons, you’ve been lied to again! Carbon fiber boards on top of an EV? Saving the environment by destroying it! Makes sense 🙄

[@markusbroyles1884]

The waste of cloth and resin is reprehensible. I never waste any resin. The cloth always gets used for ding repair or fins etc. The guys I've known who glass throw away so much !

[@juergensplieth6068]

Thx for sharing 🤙. You seal the eps blank with epoxy +microballons. After this you wait for 2 hours and then you start the carbonband application, then waiting 2 hours again, after that you laminate the Board. Is that the right timelap? Best regards

[@cerritosway]

Thanks for your appreciation. Yes Is the right time lapse, rember that time can change It depence on temperature and humidity. The epoxy should not be fully set, It Need to be a bit sticky, otherwise you Need to Sand It Down a bit. Sorry for my english.

@@cerritosway What is the measurement of the epoxy & microbubble for sealing 1 side of the board?

[@cerritosway]

Hey Damaro, Sorry for late replay. When I lower down the lamination lap i use like 40/60 grit to go faster. For sanding the glass part at the end i usually start from 150 to 400 grit. Hope Is helpfull.
