Our Next MASSIVE BUILD : The EXPEDITION ENCLOSURE (We're back BABYYY) | EE 144

[@mikeandjenn394]

Hey y’all. I am a composite specialist and would like to offer advice. Your layup schedule is nearly perfect. The only thing I would add is a piece of peel ply to the back side if you plan to do a layup on the opposite side later. When bagging leave plenty of extra bag for making pleats and putting ports in. Don’t be too sparing with it. If your bag is too small It can lead to voids in the part as well as uneven pressure causing a deformed part. When working with angles and radius’s give relief cuts in your peel ply, release film, breather, and perforated layer. So cut all the corners and do small overlaps with the materials I just said at every corner. Then When you bag it add negative folds into the bagging material to allow stretch and movement in each corner. (Have a fold in the bagging material thats flopping away from the corner or radius) It will ensure no voids and a nice tight squeeze from your vacuum pump. Make sure there is absolutely no leaks in your bagging material. This is why your first layup was dry and did not bond. You want zero air leakage. When you are vacuum bagging optimal vacuum pressure is 26.0in or higher. If you cannot achieve that high pressure with your pump it’s ok it won’t hurt the part it just won’t be as compressed. So have no worry about over vacuuming your parts. In fact the more the better. You are only going to suck air from the layup not resin. It is ok to be resin rich when bagging a part. Your breather will soak up the excess resin. The resin is actually squeezing out not sucking out. The only time resin will suck out is if there is an air leak. NO LEAKS. I saw comments about you need a pressure pot for overflow resin. This is not necessary unless you are doing what’s called vacuum infusions. This is where you do the entire layup dry and then push resin through the part. If you decide to do that I’d love to offer advice for you there. But for now will stick to bagging. Lastly do not be sparing with your Butyl tape. Id recommend don’t buy it online from a composite store if you can avoid it. It’s very common in the roofing section of a hardware store. Just ask for Butyl tape. It’s the same stuff just cheaper. You will go through a lot of Butyl tape bagging parts. Lastly to avoid excess heat when doing a layup I wouldn’t recommend applying more then 6 layers of material at one time. This will assure you don’t have an exothermic reactions which will weaken your bond or light on fire. I hope this helps you a little bit, if you have any questions feel free to ask. I will help where I can.

[@sambarrett4590]

Reservoir. He needs a reservoir in larger layups so he doesn’t pull resin into the pump.

[@letsdosomething9610]

If you did a video on vacuum bagging fiberglass I would watch it.

[@dougtooo]

The Duracel project on youtube shows Matt doing lots of vacuum bagging construction of panels he is using to rebuild their boat.

[@jackdbur]

Additionally youtube.com/@youngbarnacles is there in Barcelona Spain working on a Americans Cup project, He is a master class of carbon fibre construction having been on the build teams & crews of multiple cup racing yachts. He and his kids are also pretty good at rigging & sail trimming.

[@4ustube]

Matt did a video chat with Sailing Melody to help them with their vacuum bagging, maybe he would do the same for you?

[@Tweetystar2]

Was about to say this too

[@xLunchBoxx]

What I came here for. The most recent ha great shots of the work shop

[@ryfish5]

Matt and Mike Patey on his aviation channel would be gold mines of vacuum bagging knowledge.

[@andrewwaxman2724]

Hey Buddy, you NEED to reach out to Matt from Duracell project. He’s a complete pro at vacuum bagging and making/installing parts into pre-existing boat structures!

[@edwardh2444]

Thats where I go for my weekly dose of vacuum bagging. Matt is also a super great guy, I'm sure he'd offer to help out.

[@dansegelov305]

Hey. You should definitely get a resin trap in the vacuum line before the pump. This will prevent epoxy being sucked into the pump and destroying it. They are simple devices, often just a pot with an airtight lid and two ports in the top. Epoxy from the part will be drawn up the pipe and into the trap, but it will just sit in there instead of continuing on to the pump.

[@kathyhoward8202]

I am so impressed with you two. Anyone else would just go and buy the parts of the boat that you are building or just buy a new boat. What you are attempting is remarkable and I am so very impressed. You two are smart and creative and I know it’s going to turn out great.

[@grubbypaws3566]

Hi Bret, couple of helpful tips I hope, put your scales in a plastic bag that catches all of the spills, and it’s replaceable , a heat mat speed up the cure 4 hours at 50 degrees usually works for small items and you can do a couple in a day. Some syringes for the harder, and a silly point when pouring out a ‘thin’ liquid have the opening of the container furthest away from the pot this stops the ‘glug ’ An idea for the actual job, on the under side of the dinghy hardtop lay in some cable space for 2 forward red night lights, 2 white stern down lights and a manual search light…..just some thoughts looking forward to the rest.

[@scott32570]

Definitely check out the Duravel project lots of vacume bagging on that boat rebuild. For the hardener get a squeeze bottle that you can cut a small opening in to easier control the amount you put in. It will let you do anything from drops to steam depending how hard you squeeze it.

[@lesliefarr6922]

Have loved watching your videos…. From number one up to the latest one in the workshop, at times binged watched while on nights at work, taking me into your world on the water…. Hope Jade has a safe trip to her family keep up the good work that you both do…. will look out for your next video take care regards Les from the UK 🇬🇧

[@etagrats]

You should probably have a reservoir between the pump and the bag to gather excess resin before you suck it into the pump. See MJ's first attempt!! Also, you should practise actually infusing the resin from a supply container for when you do bigger pieces.

[@danateel]

I was going to suggest the same thing. Since you beat me to it I'll just give your comment a thumbs up.

[@pauli7457]

Thank you! ⛵

[@QluGymdad]

Another thing Matt did on Duracell was a sealed solvent bucket to keep tools in so they were always clean and ready. Each project he starts with opening the bucket.

[@lesliefarr6922]

Thanks…. Keep the good work up.

[@ExpeditionEvans]

Thank you!

[@alvarofernandezlecuna118]

Hey guys I'm from Barcelona, I work at BCN airport, I follow your channel from the beginning, my weekends are off so if you guys need a hand, I'm glad to help you, if your a near Barcelona. Regards

[@ExposingReflections]

This is pretty exciting stuff. Great video as always. Very cool filming (do we still call it that?) with the footsteps in slow-mo. You've some great techniques and could teach classes on that if you were bored. Hope everything is fine with Jades family, and she comes back no worse for wear. She's missed when she's gone. She makes a great vid into an Awesome one.

[@happybunny4732]

you guys have brought so much love into my life

[@larrybourne4176]

A couple of thoughts from experience..... I built a small boat some years ago, using the epoxy encapsulation stitch and glue procedure. I used System 3 epoxy, but they're likely all the same. My epoxy had no smell, either, but I could feel the "presence" in my nose. Toward the end of the project I started to develop a heaviness in my chest that went away when I went back out into clean air. I "believe" it was a mild sensitizing to the resin and started using a home made fresh air supplied mask toward the end. It worked. Also, proper saturation of the resin into the cloth uses very little resin. When rollering it on, I squeegeed it out till the weave was clearly visible and felt when cured, using 6 oz. cloth. Then a light coat later to back it up and "just" fill the weave. You don't want to sand into the weave. A little experimenting showed me that cloth prepared that way was very strong and flexible. With more resin, it became brittle when cured. Check yours for strength as well as dryness. That's critical for optimum strength.

[@shirleylewis3490]

Love watching you guys! Can’t wait to see how it all turns out!

[@Rendezvouslife]

Looking forward to your build videos. @Brett rockin the Altra shoes, comfortable!

[@davidbroman8391]

Excited to see your progress. Cover your scale with a piece of the vacuum bag material to keep it clean. Yes, definitely wear a mask around fiberglass. Definitely check out and maybe contact Matt at the Durrell Project.

[@texarama]

I put mine in a plastic ziploc sandwich bag. Scale still looks new.

[@jesuschrist-alphaomega]

You guys are awesome. Always nice to have a new episode.

[@philvale5724]

Hi 👋, after first running your pump, doublecheck to make sure your oil level is correct, and check before every time, There are some silicon brushes on the market, which are supposed to be very good for doing layup as they are easier to clean, And as for cutting carbon fibre that are some scissors, you can get some discs. You can use on a angle grinder, type machine or even a Dremel., and I have seen somewhere where you can get jigsaw blades, and I’ve heard of device caught a wet saw, And I suggest you use a breathing mask whenever you’re cutting material and keep it on as there will be dust particles in the air, i’m not a professional, but I have done quite a lot of layup many years ago, making radio control hydros, which had to be very, very strong, I hope this can be some help to you, Completely changing the subject, not sure where you are located, but there is a storm coming across called Irene, It’s supposed to be very bad, I hope your boat is secure, I think they said Highwinds, very bad storms relating to rain and snow and sleet, stay safe keep up the great work, look forward to seeing your next stage in your project,

[@craigsmith1965]

I teach vacuum bagging. Looking forward to your progress!

[@SJones-f9o]

Hi guys. Thanks for the videos. I have many years composite experience, boats, race cars and aircraft currently . If you have a question do not hesitate to ask. 1. !!!!Please wear safety glasses when working with resins. The hardener only takes a minute splash to blind you or somebody around you. Order some pipettes as you will find it a lot easier to dispense the smaller quantities of hardener accurately. Epoxy should be about 55% by weight to the glass, The perforated and absorbency of the bleeder fabric need adjusting to achieve the correct final weight, yes it looks dry but check weights first. Remember a good vac pump will generate an optimum 14.7 psi to your job and is capable of destroying or twisting parts. Your bleeder and breather fabrics should all contact the vacuum port by connecting with each other. the non perf in your trial is to big.

[@petesheppard1709]

SUCCESS! You learned from it, even though it didn't turn quite like you expected! 👍😎

[@loubserd]

Easy composites have a great youtube channel with good tutorials

[@clewerhillroad]

Totally agree - really well made videos covering vacuum bagging and laminating challenging shapes and sizes!

[@charlesholt8773]

Hi Brett! In my experience 5 psi is a good target vacuum level for laminating glass and carbon fiber. Have fun...

[@arkeyethenoo]

Hi Bret, I can appreciate the desire to fire up the vacuum pump and get your hands sticky to get a feel for your materials and it is evident you need to purchase a few more odds and ends. I would say you are days and days if not weeks away from actually glassing anything as you need to get the foam cores bonded together, trial fitted together, mounting points defined and finally shaped before any glass is wetted out. If you intend to run the carbon inner core tubes in the rear arches these will likely be the first things needing laminating before building the structure around them.

[@chipcleveland990]

I enjoy videos with smart people figuring things out..that said one of my favorites from 'from the beginning' was when Evan was working and Jade painted the bottom, impressive perseverance.

[@johnalden4605]

The blanket is called breather and allows the vacuum to pull the bag down overall. It is also used to bleed the resin out. The perforated film is available in different hole size and spacing for different bleeding needs.

[@bryanirwin5473]

Talk to Mads from Sail Life. I think he used this process (or a very similar one) to build the rudder for Athena. He has a few videos on it on his channel.

[@80884bpresley]

Awesome video guys!!! You all got this! See ya next time.

[@robertcoulter7592]

Always such a pleasure to watch your videos. I feel we all get more anxious about things the older we get which might explain why this feels more nervous to do than the structure maybe! Anyways thanks as always! 😊

[@_JustinCider_]

2:40 Everything everywhere except the US will be metric, so my suggestion is that you learn how to multiply & divide by ten real quick if you plan on doing more projects & repairs 😁.

[@spencercroft1839]

This video really through me off at first because the song you used is used by matt’s off road recovery in EVERY video. I thought i had two videos playing at once 😂😂

[@Matt-e4x]

Good luck on the Expedition Fabrication

[@Verb130]

In my vac bagging I'm happy if I get voids sucked out and the layup running flat with no distortion in the weave. I get worried if my vacuum gets to 2psi. I try to stop it there. At that point all your doing is making the part lighter, but not changing the structure's strength.

[@CemeteryShop-yg6gi]

Instead of frantically starting, list everything you’ll need and go get it. Watch your comments here and see what the experts are saying. Things you don’t know are important to know. Good luck Evans. 😊

[@SirCarlosMusicBMI]

So happy to see you kids. Blessings,Carlos ✝️🙏❤️😊🇺🇸

Groovy video.

[@robertlemoine3500]

Thankyou Mr . Evan’s

[@thomaswbennett4857]

Your question re cement dust or concrete dust. Cement is basically a liquid slurry that bonds the aggregate together when hardened. The hardened (cured) stuff is concrete. thus, the dust comes from the concrete. Concerning viscosity, think of your car. You probably use multi-wt oil (ie 5-20 or 10-30). In the winter, do you want to start the car with a very thick sludge or a very thin slippery oil? The multi weight oil starts off at the first number and changes to the second number as it warms up. Thus, the lower number is the more liquid like.

[@beverlyscheidt583]

I just can't get over how pretty and handsome you both are and cutest couple on the planet !!

[@TreasureoftheSun]

I like Raka marine epoxy medium, because of work time and the mix is 2 to 1. And it's cheaper than west system.

[@TreasureoftheSun]

Cabosil for thickener and graphite mixed together with medium Raka marine epoxy I used as bottom paint on my ocean fishing boat made a bullet proof bottom paint that repelled growth. And was slick low drag.

[@darkmoon855]

you guys are awsome really enjoy watching your videos:)

[@georgeingram9665]

I believe you will need a collection tank between the pump and the work piece. You do not want to get resin into the pump

[@evangatehouse5650]

I used a mason jar (canning jar) with 2 holes punched in the lid. butyl tape around the tubing. worked well and dirt simple and chea

[@chasepuzon6893]

MJ Sailing are doing lots & lots of fiberglass work, they are building a boat which looks like foam sandwich with fiberglass both sides, thought this might be good for your Dodger roof

[@tunatyme720]

Can't wait to see how things progress, talk to Raff about this they did a great job on their top although they had someone build it, he designed it 👍 good luck 💪💯🇺🇲

[@j.a.n.8456]

Yep I still love you guys. Thank you.

[@gardnep]

On building and engineering in the metric system all measurements are usually in millimetres so 4x4 becomes 100x100 mm (dressed it’s 90x90 mm). (25.4 mm / inch). Vacuum at 1 atmosphere is 14.7 psi.

[@rayb3117]

I love DYI with Brett, there is no telling whats going to happen.

[@erents1]

This is almost exactly what I want to do to my Morgan 38, I’ll be watching!

[@eralko]

I've been watching The Duracell Project rebuild Duracell from an ocean racer to a cruiser his fist editions contained a lot of vacuum bagging plus so much more I hope this helps

[@MihneaStoian]

metric system - all you need to know is to multiply or divide by 10. To quickly convert in your head, remember that 1in is about 2.5cm and 10cm is about 4in. Weight-wise, 1lb is about 0.5 kg, or 500g.

[@OttoSteiner98th]

You Got this ( slow is smooth,smooth is fast )

[@duanelarocque1541]

Found your expedition engineering youtube channel, but noticed that there is also an adventure business with the same name “Expedition Engineering”.

[@mkllove]

Brett, Did you check the batting layer above the release film ? Guessing the resin was drawn into that matrix instead of intended fiberglass. For the folds in the vacuum film (red layer) pre test fit to prep & mark where you want them and place a tiny strip of butyl or adhesive putty there. Think 3D... If you've sealed it right there should not be a need to run vacuum pump 24 hours, You could get a timer/pressure monitoring switch to cycle power on off for really big full scale parts. If the vacuum was complete, the batting materials should have gotten compressed much more and avoided the wicking of resin away from intended test part. PS Just subscribed to new channel !

[@dunkie976]

As mentioned before, it might be worth having a chat with Matt at the Duracell Project on here. He's a pro a bagging!! ❤

[@Tillersweep]

RE: "leave the pump running" You have to, but some small pumps aren't designed to run that long. If you get into that an old commercial refrigerator compressor can be reworked to be a vacuum pump and will run for days.

[@redensign9975]

That happened because you had an air leak so the resin was able to be sucked out. If everything was sealed the pump should suck to a certain pressure and stop there. In this case pressure level 11.

[@SuperSrjones]

The Orange plastic is called Mylar, to do the corners of the bag add a vertical piece of sealant and squeeze the Mylar over the extra bit of sealant to take up the extra slack over odd shapes. or just go to a decent airport and ask a LAME if you can watch him do it. You can suck down the piece without resin and add it from a connected jar and collect it from the opposite corner. You can also inject and suck from multiple places at the same time. And you don't need much suck as you can do it with a vacuum cleaner

[@MrLucretius]

Get a couple retractable blade razor knives and a box of blades. Its cheaper than carving up your fingers with a naked razor blade.

[@robinjenner7784]

Go to waches Duracell racing sail boat to a family sail boat.thay do a lot of vacuum seals in all shapes . Carbon laminates

[@nickcooper14]

You clamp the hose off once the vacuum is created. That way the resin sits in the glass. Keeping the vacuum running you pull everything out. Great try can’t wait to see the big stuff.

[@dcallan812]

try to keep the vacuum port away from any cloth-materials, just to keep the pump resin free. Try keeping the butyl tape in one bit. 👍👍

Cement dust would be from someone mixing concrete or moving cement from one place to another. Concrete dust would be from someone demolishing existing concrete, as concrete is a conglomeration of cement, aggregate, and water cured into a solid.

[@jenadidio6536]

Just saw you in a commercial for a knife during Sailing Nanjis show.

[@sodbuster8355]

you need a resin catch on your vacuum line so you dont suck resin into your pump

[@ljs66bug]

Did you get infusion epoxy that’s done by sucking the resin into the parts after the part is already under vacuum so the resin is this for that purpose. And definitely get a resin trap you don’t want resin sucking into that nice new pump 👍🏻

[@czarak9648]

Watch The Duracell Project. He uses vacuum bagging a lot.

[@fromaflafl2198]

if you are planning on a lot of vacuum bagging you should get a Vacuum Regulator so you can preciously and easely control it.

[@H2Dwoat]

Hi, take it from someone who started life with the imperial system and now uses a hybrid system of imperial and metric, metric is simple.

lways wear a mask, for fibers as well as the resin. Also, ensure that the peeply is in contact with the breather:)

[@donnordstrom31]

I don't think bagging will pull the resin out of your project, it pulls all air out of your project so the resin will infuse. If there is too much resin being used, too much for the diaper to absorb, you will get resin in your vac tube. I don't understand why your project came out dry, did you find where the resin went? Is it perhaps the wrong sort of resin, one that goes to vapor under vacuum? It was surf shop resin, it should have worked fine.

[@wjhann4836]

I assume you made a principle mistake. - You had a structure beyond, - between structure and glass was a lot of air. With extracting the air you passed the resin out of the glass. " Normal" infusion has a structure, glass over it but dry. Then this is evacuated for a long time. When there is nearly no air inside, the resin is introduced to that structure.

[@BlueChrome]

Guess it's good to make all your mistakes on small test pieces first. 😀 As others have said, you need a vacuum catch can or you will end up epoxying the insides of your shiny new vacuum pump, which will glue it up solid, trust me, it will not thank you for that. The catch can will also hold a vacuum for you for a time so you don't need to run the pump all the time - provided you have no leaks, so you still need to check on it from time to time to make sure the approx vacuum you want is still there, typically one whole atmosphere for high performance parts (if your pump can pull a vacuum that high, not all pumps can, close enough is typically good enough), but obviously use less vacuum if that would crush the part you trying to make or the mold. And the mold, hmmm, how do I put this tactfully, what you did was disaster not a mold, the sharp corners likely got crushed into the outer plastic sheet causing leaks, so as a rule molds should conform to some minimum radius on the corners both to avoid that problem, but also the fiberglass fibers themselves have a minimum bending radius they can be bent under load before they will just snap and no longer provide any strength to the final part. Take a look around your boat at all the fiberglass corners they're rounded for a reason! Lastly unless you want your mold glued to the fiberglass it should be made from some very smooth nonporous material (typically but not necessarily plastic) that has been polished to perfection with some kind of release wax. But that said you really should read up / youtube the tutorials on composite part making there is a ton of them to learn from, and some may say a considerably cheaper way to arrive at a successful part than straight trial and error. But good luck with the project, it looks like fun!

[@crashgilliam5983]

You only need to vacuum it while it’s liquid. Not all night.

[@mael6834]

Thats kind of an awkward shape to vacuum bag. The process is really best for simple flat shapes that the material can conform to prior to the vacuum being applied. Basically if you can't get the material to lie close to what your glassings the process won't do it for you.

[@jackdbur]

youtube.com/@youngbarnacles?si=IVkq_mOPuauTmwWV has managed some pretty odd shapes bagging.
