I had done the same, the side keels fit me well, the central keel gave me many problems, I did not use the vacuum pump. I will have to assemble a vacuum pump. thanks friend. excellent work, greetings from Argentina, M.A.R. surfboards
Hi there, im currently carrying out a fin making project and am focusing on laminate design. I was just wondering what lay up orientation you used for this, and whether it provided you with a good strong fin. Thanks
Hello friend I was left with doubts where in one part tou demonstrate a vacuum process, and in the other did not use only closed the mold, to make the fins should I use the vacuum or is It not necessary? Thanks in advanced and good waves... Im trying to make my own fins.
Hey awesome job! Why do you make vacuum twice for the same piece? Do you use a kind of fiber glass over the carbon furface in the firts vacuum and polyestyrene in the second?
hi thanks, first vacuum bag for carbon fiber, second vacuum bag for eps, final compression twice moulds. I make separatly because the pressure and time is diferent in each material.
Ok ok. I'd like to try for my kiteboard. It use to be smalller than yours. So I suppose that your procedure will work properly. When you are filling moulds with carbon fiber (both sides) do you fill until the top of the mound or keep some space for eps and how many space ?
You will not buy a fin like this ever! 32g one fin. Less than 100g three fins. I spend the time, 2-3h to make 3 fins, I'm looking for the lowest weight on my surfboard. If you don´t understand better buy.
isopor? mas se eu usar resina normal qual material coloco no lugar do isopor? porque isopor é pra resina epoxi, e esse material que você usa é tipo um pano ne isso?
A mí no me sirve de nada ver este vídeo, ya que no me está diciendo cómo se hace desde el principio,si todos tuviesemos ese molde,todo lo que sigue despues lo sabemos,con el molde ya no hay dificultad!!..

I use vacuum bagging for first parts and finally close with compresion
What is the cure time for extracting the parts?
it depends hardener, usually I use fast and can demold and sanding 8hours later

virus Thanks for your feedback!!I got it. But what is the purpose using Eps in the second vacuum.
eps gives to the fin the support, like a surfboard, best method to getr a fin strong and lighter

first vacuum three layers of carbon fiber, next eps, finally compression moulds
What resin system do you use to make the mold?
ua-cam.com/video/5APWjLADB5s/v-deo.html
the same process, polyester resin
What was the white sheets you were using?
Eps
why can not you watch this video, part 3. thankyou
try now
now if you can see thank you. excellent work
What have you used for the core??
eps
Craftsman.
Now you can see why carbon fibre vacuum laminated fins are expensive!
a set of fins cost approx 100$
how many hours to make one ?
no need to continue my demo ... good job though :)

es.wikipedia.org/wiki/Poliestireno_expandido
posso usar outro material?
isopor? mas se eu usar resina normal qual material coloco no lugar do isopor? porque isopor é pra resina epoxi, e esse material que você usa é tipo um pano ne isso?
