I'm no expert on this but on the Channel "Duracell Project" Matt used a layer of fiberglass between the Metal and the Carbon Fibre to prevent metal corrosion. Great work so far it all looking like it will come together well and look really good.
Random tip: For small high gloss panels, lay them up on a pane of glass. Learned that from Mike Patey's channel. Really interested in how this turns out. CF is an amazing material! At work I just watched a test on a square CF tube that survived a 50K lbs bend test.
Thank you. As a disabled veteran I must say I find your positive outlook uplifting. I feel good after a dose of one of your videos. I just wanted to say thank you to you both. My only regret is not embarking on such a voyage as yours over 50 years ago. I did it the easy way by thumb, bus, boat, ferry and plane not forgetting the odd bit of shanks pony (Walking). It doesn't matter what you encounter on the way as long as you have fun and each other. My only tip, speak and interact with locals wherever you end up on your travels. All the very best.......
CF is a conductive material. Layup fiberglass between it and your metal components to prevent galvanic corrosion. I was also thinking that the leading edge would look good if it was round. Imagine hot glueing a foam pool noodle cut in half lengthwise to the front of the arch to use as a form to lay fiberglass over. Then remove the noodle and tab the fiberglass piece in. Would give it that “airplane wing” look and be a throwback to your days as a pilot.
Adding to this, ensure ALL metal fasteners are isolated from the CF via a G10 sleeve, a layer of fiberglass or some isolation paste. If you use the paste I'd plan on changing fasteners on a some sort of routine "preventative maintenance" schedule.
Boat projects have always been my favorite part of your channel. I work with wood and metal, it's been interesting to watch your progression learning glass and now carbon fiber. Projects plus editing makes a busy schedule!
The process is cool, but I'm REALLY excited to see the finished product. I was inspired by you guys and already reached out to a company that designs and builds monster truck bodies. I sent them a link to your video which you posted the rendering and they said they could do something similar. If it doesn't cost TOO much, I'm gonna go that route. I don't have the patience or desire to tackle a project this big.
I really enjoy watching you two work together. And you don’t seem to get on each others nerves (at least not on camera). I look forward to seeing the completed cover.
Hello both, another good blog and another step forward. Now from the arm chair critic, someone else has mentioned making cf sheet, on glass or use 2 slabs of wood with food wrap and make a sandwich no peel ply needed. From my days as an A&P, beware that Carbon and aluminium do not mix, but it could/can be used if an interfay is used. Bret mount the belt sander to a block and tip and clamp it sideways doh.😄
I have been fabricating some things out of carbon fiber lately, and I swear my biggest frustration has been tracking down all of the tiny air leaks in vacuum bags. A friend let me borrow his ultrasonic leak detector and it was a game changer for me - it is able to track down and identify even the tiniest pinhole leaks by the sound the leak makes. The one I borrowed was a "VPE ultrasonic leak detector", but several companies make them. Possibly you can find one to borrow in the area, or maybe a good "win-win" sponsorship or review opportunity for the channel? The detector found a leak that could have ruined a quite expensive (for me anyway) resin infusion on a large part. My last three vacuum-bagged layups have been as close to perfect as amateur-me could hope for.
Brett, regular torch (powered by spray-can like gas storage) did wonders for me at getting rid of bubbles in epoxy, only 1 of 8 different brands of clear epoxy i tried was hard to get bubble-free with it, for others results is near instant. just make sure you do it outside of your PE plant house, lol
Really pulling for you guys! Stay strong guys. Years of safer and more enjoyable sailing after this mammoth DIY job. Keep going, guys. Maybe you could make a side gig out of teaching other's how to do this kind of thing?
Just a suggestion for the helm, instead of epoxy and carbon fiber, you should consider using carbon fiber vinyl wrap. Its cheap and easy to work with. Using your heat gun, you can get it to curve very easily around the edges and parts you want to cover. I did this on my helm and think it looks great behind the MFDs and instrument displays. Great channel. We enjoy watching your travels and projects.
If the parts you are covering in carbon/epoxy will be exposed to UV they will chalk, unless you put a coat of PU lacquer with UV absorbers in them. This won't affect them structurally, but after a short time they will look dull & grey.
Always enjoy all your videos, the two of you do such a great job at explaining everything you are doing. Keep up the great work ,can’t wait to see the finish products
🎉🎉🎉 WOW 😮❗️ There is so much Science and physics involved here. I wish that I would have learned science in school but noooo I didn’t want to learn anything 😢😢😢 I truly appreciate how you two work together and brainstorming together. I really Love watching this project coming around. Love you kids very much and would love to meet you someday. Be safe, Careful and healthy and keep on keeping on my friends. Tons of love and respect from Paso Robles, California, Carlos ❤️🙏🌊
I know this is a big ask but, I would love to see just raw video of your work with maybe a brief narrative every now and then. You guys are doing such a fantastic job, and I just can't get enough. Btw, how are the dogs doing while you are busy in the shop?
Have you thought of cushioned knee pads. A lot of your work is spent kneeling and these pads make kneeling comfortable. The things you do today could affect your body later in life.
Often when I look at the challenge of completing a long project, I don’t want to start. So I just find something to do, and do it. I find the next thing to do and do it. At the end of the day usually I can look around and say dang I got some stuff done. The next day I can light the afterburn and smile!
Do you have any renderings by chance that you can share that shows all the parts you are constructing. That would be a cool addition. Enjoying either way. Thanks for sharing.
Hey, what is the best way to send you guys info directly (text, sketches, images, audio)? I'm retired now but I have experience in vacuum bagging and vacuum bagging in molds for home-built and ultralight aircraft stuff. I watched your videos and see you running up against snafu's that I've worked against and figured out myself in years past. I would just like to pass on the little bits of practical knowledge. No sense keeping it to myself.
Guys- every hardware store in Spain sells metric tape measures, get a couple. I’m doubtful about your structure- to get the tensile benefits of carbon fiber, wouldn’t you have to wrap around the box uprights, not just make flat panels? Please make a diagram of forces- how is weight of dinghy transferred from rigging thru structure to deck bolts? How does upright box connect to metal piece inside?
Errr guys , just like to put a heads up here . A carbon arch is a really good idea , to incorporate a davit system is even better , but . I also have a project for davits , so i was really interested in being able to produce something that would fit into the mother crafts design . But It's been done before and failed . Although the actual davit arms did seem strong enough to handle the weight when loaded , the actual deck mounting failed . The deck plate pulled out of the davit bottom fixing , when tested with a light weight hard dinghy , minus the outboard . Test this carefully guys .
Wow I appreciate the link! What a bummer of a failure, certainly looked like clean work he did! very different design, materials, etc but there's definitely valuable information to be gleaned!
@@ExpeditionEngineeringJust sorry it took so long to find it , i struggle to believe it was three months ago . I figured some kind of steel back bone maybe the way to go , as that would overcome this particular point of failure , but the problem is the cost keeps on climbing with no guarantee of success . Note it didn't fail anywhere else , just the point where the load would have been at its most . I certainly think the load needs spreading out more . I hope you can figure out a path forward , and i'll keep an eye on this particular project , it would be interesting to see the outcome . Good luck .
Honest question, how long before you think you’ll be back sailing? I’m just a girl that has zero building or engineering skills or desires, so I’m just gonna set an alarm to check back when you think you’ll be done 😂
From your comments it sounds as if you are not planning to paint some of the carbon. According to many experts, carbon does not do well when in sunlight and breaks down quickly, so it needs to be painted. Sorry if that is bad news.
Realy fun to hear you having problems with metric mesurments. Don't Americans have 10 fingers 🤣 and do you not learn to count to 10 is school? 😁 You are outside US, Liberia and Myanmar, so everybody uses metric and hardware stores have all the tools you need in metric.
Please mask up when you’re cutting MDF. Both the fine airborne particles and the dust from the resin that it’s bound with are seriously nasty playmates for your lungs.

That’s what I love about you two, no River too wide, no mountain too high.✌️❤️🙏🏻😎🙃🍷
Note if you want a dust free area use a box fan and a air filter as big as the box fan. Tape the filter to the back of it .
Looking good! Suggest you do your cutting and sanding of the cured pieces outside of your “dust free” tent. Keep the clean area as clean as possible.
I really enjoy watching you two work together. And you don’t seem to get on each others nerves (at least not on camera). I look forward to seeing the completed cover.
We see Jade working hard and I am reminded of how diligently she worked n the boat's grid when you first got the boat. Great work ethic!

"I considered taking up vaping for this project, but I don't own a Subaru anymore." had me dying! 😂😂😂
thanks for the videos, inspiration/motivation to build a hard dodger on my 30 footer
Use any old trainer sole to clean the belts.

Thanks for showing this...mistakes and all. We learn by doing, right? Love it. Keep up the hardwork, looking forward to seeing the final product.
I was talking to the screen when I saw you cutting and measuring: “But… the curve!” 😂
Always enjoy all your videos, the two of you do such a great job at explaining everything you are doing. Keep up the great work ,can’t wait to see the finish products

great video and Jane she's a artist with a big heart 👍⛵👍🛠
Love this series guys thank you! How did the stove conversion go?
Nice work.
How many layers of fiberglass and carbon fiber did you use?
Considered taking up vaping, but I don't own a Subaru! Got me dying!
Hahahaha. " I don't own a Subaru anymore" . Factually accurate description of a wrx owner.
So the beat goes on. Grab the gusto!
I think the little lump is where a rail will be fitted, or may something for the davit

Cava is sparkling wine from Spain. Either rose or white
The never ending project 😢 lets get back to sailing
If adding metal,keep in mind galvanic corrosion Don't let the Carbon Fiber touch the metal...

Thank You.
Wait, did he say he doesn't vape anymore because he doesn't own a Subaru ? props.
It's not often you do something that is counter productive, but cutting and sanding inside your dust protection environment is rather daft..🥴
Nice @sailingyaba shirt! Love their channel as well!
One small question, are the epoxy, taht you are using uv resistant?
Its too late but weld the bolt through the metal and all you need is a backing plate and nuts to attach it to the boat.
Nailed the time lapse Narration. Had me chuckling out loud, thinking , not bad for a pilot.
i did have to consciously refrain from eating the microphone!
Or using the 2 octive down voice😅.
You'll have to do one piece narrated in your pilot style. Could be hilarious if you did it with a lot of dry humor

little bit of soapy water for leaks on your vacuum bag. works for bicycle/car tires?

this way you can clean them instead of wasting belts
ah USA and your kryptonite, the metric system
brett, we used a 2"x2" eraser to clean our sand paper at work
And would you hooligans get some knee pads? Arthritic ptsd watching kneeling without em
I have a feeling after four weeks, that this project is not going well.
You will need some UV protection on your carbon skins.
Are those real ponchos or are they Sears ponchos?
surely a tape measure, and a ruller etc with the propper measuring "system" is dirt cheep. oh and metric is the correct measuring system hahahaha
Don't meen to be a smartA, but a measuring tape from a local hardware store is 2-5 €, and in metric. ;)
Be sure that the metal piece will be well isolated from the carbon. Otherwise it will corrode no matter how RF it is.
Do you know that you have to insulate the carbon fiber from the steel.
I love you guys, but you need to put yourselves in the water. Can't take too much of this. OsoYolo, Antigua Guatemala.

Why metal - g 10 and or carbon Fiber blocks would be better no corrosion
