Fantastic video. I had never seen that exact process before. It seems pretty slick.
Another video from the Master at work....Truly Inspiring Nick!
I'd be curious if carbon and wood is a good fit? I thought carbon is almost not elastic at all but wood is. So wouldn't all the tensile strength rely completely on the carbon fiber (because it would crack first)?
I thought this was the reason why fiberglass and wood mixes so well because they have similar elasticity.
Thanks for the awesome videos!
In this context the wood is acting as a core, keeping the inner and outer layers of fabric separated. It is likely that all the interior loads would be directly transferred to the CF, causing the CF to fail before the wood, but I'm OK with that.
I'm not making fighter jets, I don't feel the need to optimize everything to the best conceivable layup. This infusion technique does further optimize an already over-built kayak for the use it is going to get.
Thanks, that's what I figured.
I was wondering the same. Good question and good answer.
I really like this video. Thanks for posting.
I assume the boat will have better saturation into both the carbon fiber/glass, and the cedar itself. In your own personal opinion, do you think the weight gain vs. strength and cost of vacuum infusion vs. hand lay-up is worth it?
It's not so much about weight, but guaranteed correct laminate to resin ratio and lack of voids (consistency), that make vacuum bagging worthwhile. On something this small, the weight advantage would be very small.
a really nice finish. Is it possible to achieve this finish without so much waste of plastic?
This vacuum infusion method does go through a lot of material to make a first quality layup. It is possible to get results that look almost as good with a hand layup, which would not need the plastic.
I love the process and have been doing it for years but now feel guilty about the amount of waste plastic and unrecyclables thrown away at the end!
love your vids. That's a lot of work setting up and installing for that method. Better off staying with the strip method.
Have you ever though about getting a large tube or center fold vac bag? It would save you a ton on bag tape! Kayak looks awesome!
Is is possible to heat seal vacuum bags?
Good evening and congraturation ,
my I ask what model of pump did you use? I wuld like to try to do the same on a your gGuillmont fast double kayak and i wander what pump i should buy.
Nice video! I know it’s old but had a question and hope you get it. How long did the actual infusion take from the time you unclamped the resin line? And what cfm vacuum pump were you using? About to embark on my largest infusion and taking as much in as I can! Thanks, James
This took quite awhile. Probably about an hour. I was using MTI tube which I think slowed down the draw. The pump was about 3cfm. Not particularly fast but it could draw a deep vacuum. I am still learning. I would like to experiment some more.
Nick Schade awesome, thank you for the quick reply! I am getting geared up to do a foam core/carbon fiber technical poling skiff for flats fishing here in Florida. I’ve done plenty of wet lay and bagged, infused a lot of small parts, but nothing of any size. This boat will be an 1854 with a max beam of 71” so it’s quite large bu diy standards! Thanks again, James!🙏

Good job!
great video!! that was wonderful!
Up to my understanding, such a strong vacuum pulls air from wood itself too, and during infusion, the resin should penetrate the wood way much deeper than during hand layup. However, the fabric should take up way less resin in vacuum infusion process, than during hand layup.
So, according to your experience, what was the balance between these two effects? Is it possible to save some weight using the vacuum infusion process?
Did you used this technique for the external fiberglassing too?
There were indications in places that the epoxy got pulled 4-6mm into the grain of the wood (along the grain). So, there is good penetration which should improve the bond between the wood and the fabric.
The compacted fabric definite took up significantly less resin than a hand layup. Overall weight was less than a hand layup, but more importantly the whole layup was just better quality, smoother, cleaner. It really looked great.
On this build I did not infuse the outer glass, but I have since this was recorded. It worked well.
Nick, thank you for your quick response! As I'm picking up more and more knowledge from your book and videos, it looks more and more evident, that building a boat is not a nailed down manufacturing process, but series of activities of different crafts, preceded with series of decisions.
I'm gearing up to build a small kayak fleet for my family, and information from your publications renders that decision making process way much easier.
Once again, thank you!
There are lots of options for how to build strip planked boats. I would not recommend infusion right away unless you just really feel like taking on a challenge. While the results are nice, it is a lot of work for incremental improvement.
No final decision made yet in any topic, just accumulating knowledge. I'm at least two month from ripping up the first board.
Anyway, may I ask, Nick, what species of wood you used on the bottom of the Petrel Play?
The Petrel Play is all western red cedar
Great video Nick. How long did it take to fill the cloth with the resin using this technique? Are the results noticeably better than doing this by hand?
Paul Ernsting It took about 30 minutes to fill the cloth on the hull. The results are beautiful.
Nick Schade
That is quick! Your description of the process on your link was quite helpful. Thanks for the post, looking forward to seeing more projects
Great video. How much would you say just materials cost. And also, any reason why you didn't degas the epoxy resin?
Unfortunately, I did not do a good job keeping track of materials cost. I was too focused on not messing up all my hard work up until this point. I didn't degas because I didn't think I needed to and wanted one less step in the process to worry about. Degassing may have helped, but not much.
Nick Schade Thanks for sharing.
You don't have to use release film in vacuum infusion process. Mostly release film uses with vacuum bagging process. So you can save from money and time.
What is the brand of spray adhesive you used for fixing first layer of carbon. its look like airtac spray. I wonder any spray adhesive is applicable?
I have had some issues with the release film. I think I would get a slightly better layup without it because the leading edge of the resin gets ahead in the flow media relative to the fabric, sometimes I get a tiny air spot trapped in the cloth.
I use the release film because I was worried about removing the flow media. The peel ply is probably sufficient.
I went with Airtac spray. I know some people use Super 77, but being new to infusion, I didn't want to throw in another wild card.
Why use both cf and gf? Carbon is cheaper then a similar or higher strenght gf but dont see why mixing them. If you want more pierce resistance swap either one for kevlar on the outer layer
In order to give the interior a fine finish, I knew I was going to have to do some sanding. If I had not applied the glass over the carbon, I would have sanded into the CF immediately. The glass was a bit of a sacrificial layer to absorb the sanding.
Why do you use fiber glass in this kayak?? Carbon fiber alone should do the trick. Or this is for just bringing down the price of this project? Great videos by the way. I really admire your talent sir :)
+zodziusavas I knew I was going to need to sand the inside prior to applying the interior finish. The glass allowed me to sand a bit into the surface without hitting the CF. I could have gone with a lighter glass layer for the purpose, but I wanted to give myself some room for error given this was my first effort.
Nick Schade why use peel ply if you are going to sand it anyway?
Daniel Herbert Partly just for the science. This was the first time I experimented with infusion and it was a bit of a learning process. I do feel the peel ply left a better surface than release film would have, so less sanding was needed.
What kind of electric shear/rotary tool are you using to cut the excess cf/fiberglass off with? It's a nice compact tool...

helo nick great stuff just wandering why you use the release film in the infusion. it is pretty allright with out it.
+Petr Major Just being cautious. Since this was my first experiment with infusion, I wanted to play it safe. As I have gotten more experience, I am thinking it may actually be causing me some problems when I'm doing thin layups. I'll be experimenting without it in the future.
i thought that might be the case. i do it with out it and it works just fine.. by the way great boats i learned so much from your videos. now i do this. www.galeforcekayaks.com
Petr Major Looks like you are doing nice things with your boats.
Hi Nick - In addition to your build, I enjoyed the music. I attempted to identify it via the interweb and found a tune called Inspector Trumpet by DJ Peter however it is only 1:23 long. The music in your video extends beyond this with additional improv. Can you name the tune and where I might find it? Thank you!
The music is something I put together from a variety of loops provided with the app GarageBand on my Mac. The loops are short (1 to 8 bar) selections of individual instruments. I combined loops from a rhythm guitar, pocket bass, "Rasta" drum kit, Clav, and horn section.
It sounds like DJ Peter used some of the same horn section loops for his "Inspector Trumpet". I frequently get take-down requests from UA-cam for this music, because lots of people have released works using the same loops through music distributors who then automatically send a take-down whenever their algorithms detect similar loops.
GarageBand has some quality loops, it almost makes me feel like a musician to arrange them together is something that sounds halfway decent, but I can't call my music an original work, its just an original arrangement.
May I obtain a copy? I like how you arranged it. Cheers!
contact me via www.guillemot-kayaks.com/guillemot/feedback with your contact info, I will send the GarageBand file
Very nice you make your own music and your own kajaks :)
Très cool
Why are you combining carbon fiber and fiberglass?
I knew I was going to have to do a little bit of sanding on the inside. The fiberglass assured I had enough resin thickness on top of the CF that I would not sand immediately into the weave of the carbon.
Nick Schade I understand. It's just cheap insurance.
Just 1 layer of CF?
Yes. For a kayak of this size, one layer is plenty.
Ok
This makes me never want to paint on epoxy ever again
That is impressive. Ah, technology.
Save the Planet. What happens to all the plastic and liners. God help us all!!! How many guillemots have died eating waste plastic. Make your canoes from waste plastic instead.
