Your first part looks good. I just wanted to give you a couple more suggestions for your journey. Try to place your vacuum port towards the middle of the layup as best as you can. Reason for this is because you actually loose vacuum pressure over distance so to get an equal squeeze it’s best to be centrally located on the part. You can also use more than one vacuum port if you have them. Another suggestion is to remember that carbon is conductive and will corrode metal parts. So make sure to place a layer of fiberglass over any locations that will come into contact with hardware or dissimilar metals. It’s easier to just add a bit of fiberglass to your layup right away verse have to go back and sand the carbon to add glass later. Keep up the good work thanks for the videos.
skateboarder here, nice job on the ramp lol. no but all jokes aside you guys bring a lot of joy and positivity into people's lives and for that I say thank you =)
i wanted to say the same thing. Like skateboarding down the road to the ramp at age of 14. until later when a half pipe was created in the neighborhood cool. i love their channel.
The foamy oil in your vacuum pump, the brittle epoxy and the shorted space heater all seem to point to excess humidity in your work space. You might need a dehumidifier. Also, you might want to put something down under the bottles you're using as weights to keep the work piece from pulling up, something to spread that weight more evenly. Pretty darn good for your first piece of composite construction, though!
The carbon fiber dust is conductive and that is probably what took out the heater. I worked in a company that made carbon fiber and the electrical panels had to be protected from it.
Get you a small box fan and duct tape a good quality a/c filter to the back of it. Then cut a hole in your wall and put it in there. Turn the fan on low speed and you will have a positive pressure room to help keep the dust out.
unless you make it crazy super thick, the rigidity of composites actually doesn't have enough deflection. Ironically, steel or aluminum has enough deflection to not deform. What I'm suggesting is when you have a composite structure with a high static load someday it will fail and when it fails it will be catastrophic. Do you know how much static weight you are expecting on the davits? I would be worried about long term static loads?
I worry about moving forces, not just static loads, weight of dinghy amplifies movement of boat and forces on structure. Also, you talk about “arch”, which is one continuous structure, but you seem to be using flat panels to build a frame with critical joints at feet and corners. Please go talk to an engineer in Spain.
Some comments/tips from a vacuum bagging nerd from way back... When you use a foam core with VB'ing the carbon/glass/kevlar can be forced into making a 90 degree bend. This is a bad thing (tm). But you can feather the edge of your foam core -- just sand a slight bevel on the top edges for, say, 1/2 an inch to an inch. That way the material takes a gentle bend and your top and bottom layers of carbon/glass/whatever are bonded to each other at the edges as well as to the core. Also, be careful of where your foam cores meet when using more than one piece. If there's any movement when you pull the vacuum, you can wind up with the fabric being pulled down between the cores which may lead to a slightly weaker spot. Way back when I was helping an engineer make parts for an aerobatic aircraft (ailerons for a plane called a rebel I think?) The foam cores we cut didn't go clear to the edges of the part, just nearly. I think we had an inch or so of just pure material around the foam cores and the cores had the taper sanded into them I mentioned. In our case (for the curious), we made a top and bottom part. The bottom of the aileron was like a dish (bottom skin, sides, and leading edge of the control surface) and the top was just a flat plate. Then we sanded the edges (the part that was pure carbon, no core), drilled them, clico'ed and bonded the top to the bottom and a new aileron was born. :-) Also, if there's any way you can get an on/off switch for the pump to keep the vacuum at a certain level, that's better than just turning it off overnight. Just sayin'. Yeah, I know, might not be possible. I could never afford one for my own VB'ing (making wings for RC gliders). But I'd just babysit my stuff for 8 or 10 hours so I knew I had a good (but not too hard) vacuum at least until the resin hit the D-stage. Anyway, kudos to both of ya for doing the vacuum bagging! It's a lotta fun. I always thought it was like Christmas every time I opened a bag to see the part I'd spent so much prep time on to see if it turned out like I'd hoped. And watch out for how sharp parts edges are when de-bagging them.
I feel as though your mold should have some sort of skeletal framing within the carbon fiber structure that you're building. There will be some really strong forces stressing your structure, both wind loads and weight shifting loads from the dinghy, while underway.. I don't know if the foam wrapped in carbon fiber will be strong enough. I'm not an engineer and I know that carbon fiber is strong but, it just makes sense to have an internal frame of some sort for strength. Especially when you compare how the stainless steel framing is designed for the same purpose. But, It will be a treat to watch you guys learn and build this much needed extension of your home.. Really cool..!
Yes I am exactly, I think the edges of your panels are doing the structural work to resist bending, need to be more like a shallow I beam than flat panel. How does foam + carbon fiber resist compression? Maybe you need to build a small model first and load test it
The epoxy probably has IPD (Isophorone diamine) hardener and this enables a fairly brittle initial cure, you must postcure at elevated temperature acording to producers instruction to unlock elongation properties.
Me alegra mucho que estéis en España, trabajando en vuestro proyecto y disfrutando de mi país. Confío que el resultado de vuestro esfuerzo de buenos resultados.
A quick mixing tip. I like to use 2 cups for mixing. Mix the epoxy in one cup then transfer to a clean cup and continue mixing. This will eliminate the chance of unmixed epoxy going into the parts being made.
Love the hermetically sealed space you have created for the construction of your project. However don’t you think it would be wise to do all your dust producing cutting outside of it?
Do you ever think about the composite company getting your orders, answering your questions, then later, seeing your videos, subscribing numbers, and going, “holy crap, we had no idea! If we had known, we could have offered EE a space in our shop, a shop instructor/specialist!” I do.
@totalboat did this for us when we redid our countertops! They would have done the same for this project because they are awesome, but logistics of being in Europe made it no fun
Looking good! If you hold your epoxy cup on the sides/ not in the palm of your hand you substantially reduce the heat transfer from your hands to the epoxy that can set off the exothermic reaction in epoxy.
Nice work with the layup!! Since I never remember when I buy things, I've started writing the date of purchase/delivery on things like tool batteries, and even tools, especially electronic ones. That way I know if I'm getting good service life out of them. This goes especially well for things like 3rd party/knock-off parts, like this knock-off Dewalt batteries, as you won't remember in a few months.
Brett, no shame dude, but I think I can tell where Jade took over the video production. P.S. Her music is better, too! 🤣 No matter. I love it all. Keep it coming!
Well it's no secret that she is a gifted editor, no doubt better than me. But no way is her music better! (besides I pick the majority of the music for both channels) 😁
Howdy Youngin's , Love this new RUclips format. I read all the comments and as usual some really good comments. I woke up this morning thinking about your new fiber project. and how fortunate you are to have a 3.2k data base..Haha Well anyhow I have one question. If you sandwich your carbon fiber with foam does that make it a giant drycell battery? I'm sure you have thought about this. You guys do a great job researching all your projects.. Love you and have great hope for success in this project.
Cool what you are trying to do..If you succeed I'm thinking the structure is going to act like a sail. As the wind blows on the structure it may cause steering issues....Hope I'm wrong..There is a reason most use aluminum or stainless tubes...
I have looked for left handed scissors for years and had people look at me real strange. Of course they were all right handed. Also would love a left handed egg slice, one with the angle on the end going the other way, about as rare as “ Hens Teeth “ . Have to draw a diagram,:-))))
A carbon fiber sandwich!?! That’s a bold move, Cotton! You make an excellent technical work team. 👏 👏👏 I try to avoid buying electrical/electronic stuff off Amazon. I’ve been disappointed too many times with shoddy products or repackaged damaged goods.
a little worried that when you finish the build of it it looks too flat without and curverture to the framing of it to suit the curves on the boat. I hope not tho. loving the way you both enjoy doing these projects together.
If you are anything like me then the hours working on the boat outnumber the ones sailing it - well mine have been power boats, but you know what I mean. It turns out I quite like working on boats, who would have thought 🙂
Don’t forget to create strengthening stringers for your build. Also get an electric shear for your cutting needs. Also I agree about the sound levels. Make it more of a background and not so much in your face. Great work otherwise!! 🎉
Awesome work, this should be fun. The "twice as good" as the manufacturer batteries might not show out furing short term use. My knockoff Makita batteries were fine for about a year, then started overheating during charge and use, then died at about 13 months of 5 days a week use. 4-5 year old Makita batteries are still like new
Well I’m enjoying this content enough about the music you will fix I’m sure nobody could ever say you’re not workers because this project will be big bold and beautiful cheers from Perth Australia
It may be too late but…what if you make a whole rectangle panel and then cut out your part after? It will have the curve and you will have nice clean edges. Look at the way “the Duracell project” makes panels using foam and fiberglass.
hey jade, cut the gain on the music by 6db, the voice should come through, music should be in the background, great editing otherwise, say hi to the pups!
You should look at Formula one cars. The cars are built mostly with carbon fiber. They are the best with the technology and implementing carbon fiber than anyone.
great job you are doing with the composites. Just one word of advise. I can see you are very conscious about your PPE. However, please ALWAYS where Nitril gloves when handling epoxy resin and do not touch with bare skin. I speak from personal experience that even continued small jobs handling epoxy unprotected can have adverse effect on your heath. I have developed a serious allergy as a result of composite work without PPE.
Looks Great! Any reason why you didn't smooth the edges of the foam and wrap the carbon round? It would still be a tight bend, but the vacuum should hold it in place. Maybe worth an experiment.....? It's SO easy being an armchair expert! Love the focus on DIY, gives me another channel on top of Mads, RAN and MJ Sailing to get through the winter months - Best wishes from a cold and snowy UK!
Hi guys - I remember you were taking on a little water approaching the Azores but never saw the resolution (I have looked!) - could you say what happened or which movie covers it at all please? Best of luck with this project, great movie thank you 👍👏👏👏
This looks like a fun but scary project. I’m assuming that these materials are expensive??? I Love so Much How you two tackle projects and just go for it. I would love to try this method just for fun 🤩 But I’m not sure what I would do 😂. Blessings,Carlos ✝️🙏❤️😊🇺🇸 from Paso Robles, California
You should! I had a blast doing vacuum bagging. In my case, I learned by helping actual engineers working on actual aircraft, but on my own I made new wings for an RC slope glider I had (ie, a super thin wing for going stupid fast on high wind days, a high lift aerobatic wing that was short for fast roll rates, etc). I'd find an airfoil I thought looked interesting/fun, make thin plywood forms of it (one for the root of the wing section, one for the tip), attach 'em to a foam block and then with the help of a friend, use a hot wire cutter (piece of ni-chrome wire suspended in a wooden bow with a power supply shorting on the wire to get it hot) and carefully cut the foam core for the wing. 'Took practice but this meant I could do cool things like use a thin/fast/low-drag airfoil at the root and a thicker airfoil at the tip. Then the resulting wing had better stall characteristics (the tips of the wing wouldn't stall first - less chance of a spin). Anyway, I started very humbly -- just a hand-me-down pump given to me by an A&P who worked on full-scale gliders I helped when the weather at the gliderport was no good for flying or when I had no instructor, and whatever fiberglass or carbon fiber I could get at the hobby store. I did purchase decent 24 hr epoxy. The pump was old, loud, and had to be manually oiled and I didn't have a fancy vacuum port or resin trap. 'Just used a quart jar with two copper pipe soldered into the lid so any resin that might get sucked up the vacuum hose would land in the quart jar rather than going into the pump that way. Perforated plastic can be bought, or you can just get a sheet of thin plastic, fold it up into a square pad and poke holes in it with a punch or the point of a compass. Sop cloth can be had just going to a fabric store and buying cheap cloth. Peel ply is a "nice to have" if you're on a budget. I was cheap (going to college at the time and broke) so I just sanded finished parts that were to be bonded to something later or painted. I found foam cores in scrap bins on building sites, though that was a bit hit or miss and you can probably get better foam cores if you purchase them. :-)
Since you mentioned Atlantic Towers I took a look. Frankly I would do that- it has actual structural engineering designed for significant weight and forces. Your proposed carbon/ foam/ fibreglass composite doesn’t seem to have had any engineering calculations to it, just a guess about what looks right based on no data. Please tell us you have based your design on some data? Other commenters note that while carbon fiber is strong in tension when it fails it can be sudden and catastrophic. I worry about suspended dinghy putting heavy loads on your understrength arch. I am thinking now of that carbon fiber submarine….
Just don't imagine that carrying the dinghy on the davits at sea is smart. I have seen many mishaps .....much much safer to carry the dinghy inverted on deck. The davits are still useful every day or on short, sheltered hops....
You guys are awesome! This is an ambitious project with your attention to detail it will come out amazing. I watched Mike Patey build this plane using similar techniques. ruclips.net/p/PL9OFkVHYEhoFUPV78e3hh0TVPMhYI73f9&si=exwKUC_DVGMMvpgc
Be interested in how your knockoff batteries perform. I once bought a similar offering for an oldish Dell computer, that I didn't think warranted a genuine battery cost. Damn thing wouldn't even charge properly, after pulling it apart, of the individual cells, half were just cardboard tubes. Pleased to see you've got Festool for the serious tools.
I just watched your video and I noticed only one sheet of carbon fiber and if I remember right from a documentary that carbon fiber gets it’s strength from the fibers going different directions in several layers. Also that epoxy will not last very long if it does not flex like fiberglass.
It depends (wrt. to direction of fibers in cloth) on what you're building. For example, if you're making a wing, you're right, you want it strong in torsion (twisting) as well as span-wise and chord-wise. In that case you might (for example) layup the skins of the wing with the cloth on the diagonal - the fibers making X's along the wing to bear any twisting loads. Then lay up spar caps of the wing (which take the span-wise bending loads) using carbon fibre where almost all of the fibers are uni-directional, running the length of the wing and another layup for the shear web (the vertical part between the spar caps) with the strands laid to oppose shear forces between the spar caps. Or if weight is less of an issue you could just layup the skins in two layers of heavier material, one with the fibers running diagonally (this should be the outer layer of the wing skin) and an inner layer with the fibers running span-wise and chord-wise. In their case, because the structure they're building will eventually be sort of box-like (the boat being the bottom of the box) they'll get some extra rigidity from the structure itself. (sorta like a how a bi-plane wing can be made stronger than a mono-plane by virtue of the box shape).
Not sure how much of a pain in the a$$ this is but can you add some of your fav builds your other channel? Really love watching you guys and wish you both all the best!
Enjoying the videos, but the music volume is annoying. I don't know if you can change it compared to your voices easily. I have to turn you both up to hear what you say, then the music starts mind cracking loud. Yes, I'm old, lol. Hopefully you can make the music much lower than your voices, and viewers can turn it up if they want to.
Your first part looks good. I just wanted to give you a couple more suggestions for your journey.
Try to place your vacuum port towards the middle of the layup as best as you can. Reason for this is because you actually loose vacuum pressure over distance so to get an equal squeeze it’s best to be centrally located on the part. You can also use more than one vacuum port if you have them.
Another suggestion is to remember that carbon is conductive and will corrode metal parts. So make sure to place a layer of fiberglass over any locations that will come into contact with hardware or dissimilar metals. It’s easier to just add a bit of fiberglass to your layup right away verse have to go back and sand the carbon to add glass later.
Keep up the good work thanks for the videos.
skateboarder here, nice job on the ramp lol. no but all jokes aside you guys bring a lot of joy and positivity into people's lives and for that I say thank you =)

100%
The carbon fiber dust is conductive and that is probably what took out the heater. I worked in a company that made carbon fiber and the electrical panels had to be protected from it.
Get you a small box fan and duct tape a good quality a/c filter to the back of it. Then cut a hole in your wall and put it in there. Turn the fan on low speed and you will have a positive pressure room to help keep the dust out.
When I do boat work i have a pair of electric scissors for cutting fiber, i couldn't imagine doing it with normal scissors now glad you got a pair!
Get a cheap timer to run the vacuum pump at intervals to maintain vacuum a bit longer unattended.
unless you make it crazy super thick, the rigidity of composites actually doesn't have enough deflection. Ironically, steel or aluminum has enough deflection to not deform. What I'm suggesting is when you have a composite structure with a high static load someday it will fail and when it fails it will be catastrophic. Do you know how much static weight you are expecting on the davits? I would be worried about long term static loads?
Like the 787 Dreamliner: 15% titanium by weight.
I worry about moving forces, not just static loads, weight of dinghy amplifies movement of boat and forces on structure. Also, you talk about “arch”, which is one continuous structure, but you seem to be using flat panels to build a frame with critical joints at feet and corners. Please go talk to an engineer in Spain.
Some comments/tips from a vacuum bagging nerd from way back... When you use a foam core with VB'ing the carbon/glass/kevlar can be forced into making a 90 degree bend. This is a bad thing (tm).

That way the material takes a gentle bend and your top and bottom layers of carbon/glass/whatever are bonded to each other at the edges as well as to the core. Also, be careful of where your foam cores meet when using more than one piece. If there's any movement when you pull the vacuum, you can wind up with the fabric being pulled down between the cores which may lead to a slightly weaker spot.

Laying out your patterns on the material to find the best usage is called nesting. Really enjoying Expedition Engineering. You two are a great team.
The epoxy probably has IPD (Isophorone diamine) hardener and this enables a fairly brittle initial cure, you must postcure at elevated temperature acording to producers instruction to unlock elongation properties.
Fantastic, looks perfect.
Y’all are awesome. I haven’t commented in a while but it is awesome how well y’all work together.
Love the community, "Sailing Yaba" T-shirt - does not go unmissed friends!
Great seeing you guys doing your own stuff I've watched the whole boat build you guys are great ! You do great teaching!!!
Expedition kick butt Engineering
Just remember 2 bend one way and 2 bend the opposite way
Fun fun fun to watch you two. I learning by watching and reading everything I can find to better understand the process.
I LOVE this type of content! You are using the skills you have and growing them into something more. This is how we all learn. Thank you!
I know nothing about composites so I will hold my opinion. Always in joy your content.
Love the content!! You guys are awesome! Nice you can work together without getting on each other’s nerves! 🎉
Me alegra mucho que estéis en España, trabajando en vuestro proyecto y disfrutando de mi país. Confío que el resultado de vuestro esfuerzo de buenos resultados.
I'm looking forward to seeing how it comes together..the attachment system will be interesting to see 👏👏👏
A quick mixing tip. I like to use 2 cups for mixing. Mix the epoxy in one cup then transfer to a clean cup and continue mixing. This will eliminate the chance of unmixed epoxy going into the parts being made.
we totally agree and recommend this to all our epoxy users!
Sand bags will work for weight. It’s heavy and will form to the mold below it.
Love the hermetically sealed space you have created for the construction of your project. However don’t you think it would be wise to do all your dust producing cutting outside of it?
Reminds me of when you started rebuilding the boat…. Great start
Super interesting stuff! The first part is done! Beautiful from far away - LOL
Do you ever think about the composite company getting your orders, answering your questions, then later, seeing your videos, subscribing numbers, and going, “holy crap, we had no idea! If we had known, we could have offered EE a space in our shop, a shop instructor/specialist!” I do.

I have been dreaming of doing some stuff in carbon fiber! Thank you! we can share learning curves!
Awesome as always!
Make sure you get all the air out. Is most important to do.
Nice soundtrack… Gamma Skies now added to my workout playlist….
Nice work with the layup!!

Congrats guys!!! Amazing how you are so brave to start proyects like this!!!! Keep going!!!! It would be nice in visible carbon fiber😅
Epoxy settles in containers, mix well in containers prior to catalysing.
Brett, no shame dude, but I think I can tell where Jade took over the video production. P.S. Her music is better, too! 🤣 No matter. I love it all. Keep it coming!

Jade I would love to read your book when you get it finished. Oh and Brett if you haven't read BACKYARD STARSHIP check it out. It's a good one.
Don’t forget to create strengthening stringers for your build.
Also get an electric shear for your cutting needs.
Also I agree about the sound levels. Make it more of a background and not so much in your face.
Great work otherwise!! 🎉
Awesome work, this should be fun.

Can you explain a bit on how these become finished pieces? I don't have any composite experience so I'm trying to figure out how these come together.
I think Paikea, aka Young Barnacles, is in Barcelona , Shayne has alot of composite experience.
Well I’m enjoying this content enough about the music you will fix I’m sure nobody could ever say you’re not workers because this project will be big bold and beautiful cheers from
Perth Australia
It may be too late but…what if you make a whole rectangle panel and then cut out your part after? It will have the curve and you will have nice clean edges. Look at the way “the Duracell project” makes panels using foam and fiberglass.
3rd channel for product reviews? Expedition Evaluations! 😂
😂 2 channels is more consuming than expected, 3 could be our undoing!
very nice work.
hey jade, cut the gain on the music by 6db, the voice should come through, music should be in the background, great editing otherwise, say hi to the pups!
oh my Lord.....this will take a long time.....
Welding stainless steel is much much easier but would be boring content, so all power to you, you do make good content.
You should look at Formula one cars. The cars are built mostly with carbon fiber. They are the best with the technology and implementing carbon fiber than anyone.
great job you are doing with the composites.
Just one word of advise. I can see you are very conscious about your PPE. However, please ALWAYS where Nitril gloves when handling epoxy resin and do not touch with bare skin. I speak from personal experience that even continued small jobs handling epoxy unprotected can have adverse effect on your heath. I have developed a serious allergy as a result of composite work without PPE.
Yup that’s how you do it vac to the form
Where are you doing the build? 🤔
I figured Jade was a superior being (Lefthanded)
Ok, my theory is that you 2 really wanted to glass some stuff and this is the thing with the most glass work.
Your doing fine fiberglass is not hard.
Looks Great! Any reason why you didn't smooth the edges of the foam and wrap the carbon round? It would still be a tight bend, but the vacuum should hold it in place. Maybe worth an experiment.....? It's SO easy being an armchair expert! Love the focus on DIY, gives me another channel on top of Mads, RAN and MJ Sailing to get through the winter months - Best wishes from a cold and snowy UK!
To sharpen the cisors, u can cut some aluminiumfoil
Music way too loud. I keep having to adjust the volume.
Nice video. Good reference mivie Toc Toc
Hi guys - I remember you were taking on a little water approaching the Azores but never saw the resolution (I have looked!) - could you say what happened or which movie covers it at all please? Best of luck with this project, great movie thank you 👍👏👏👏
Yeah electric heaters and hand tools don’t like carbon fibre filliments floating round in the air tends to trip things out lol
Diagonally brace the back of the rack
Yes, please let us know what you found out from Battle Born.
Maybe consult "Duracell Project" about that Vacuuming thing for the pieces? He seems pretty versed in that sort of thing...
What happened to your original channel?
That’s for when they are sailing,they land lubbing.and working on da parts right now
This looks like a fun but scary project. I’m assuming that these materials are expensive??? I Love so Much How you two tackle projects and just go for it.
I would love to try this method just for fun 🤩 But I’m not sure what I would do 😂.

You should! I had a blast doing vacuum bagging. In my case, I learned by helping actual engineers working on actual aircraft, but on my own I made new wings for an RC slope glider I had (ie, a super thin wing for going stupid fast on high wind days, a high lift aerobatic wing that was short for fast roll rates, etc). I'd find an airfoil I thought looked interesting/fun, make thin plywood forms of it (one for the root of the wing section, one for the tip), attach 'em to a foam block and then with the help of a friend, use a hot wire cutter (piece of ni-chrome wire suspended in a wooden bow with a power supply shorting on the wire to get it hot) and carefully cut the foam core for the wing. 'Took practice but this meant I could do cool things like use a thin/fast/low-drag airfoil at the root and a thicker airfoil at the tip. Then the resulting wing had better stall characteristics (the tips of the wing wouldn't stall first - less chance of a spin).
Anyway, I started very humbly -- just a hand-me-down pump given to me by an A&P who worked on full-scale gliders I helped when the weather at the gliderport was no good for flying or when I had no instructor, and whatever fiberglass or carbon fiber I could get at the hobby store. I did purchase decent 24 hr epoxy. The pump was old, loud, and had to be manually oiled and I didn't have a fancy vacuum port or resin trap. 'Just used a quart jar with two copper pipe soldered into the lid so any resin that might get sucked up the vacuum hose would land in the quart jar rather than going into the pump that way.
Perforated plastic can be bought, or you can just get a sheet of thin plastic, fold it up into a square pad and poke holes in it with a punch or the point of a compass. Sop cloth can be had just going to a fabric store and buying cheap cloth. Peel ply is a "nice to have" if you're on a budget. I was cheap (going to college at the time and broke) so I just sanded finished parts that were to be bonded to something later or painted. I found foam cores in scrap bins on building sites, though that was a bit hit or miss and you can probably get better foam cores if you purchase them. :-)

Carbon fibre is tricky stuff to cut. Try carbon cutting kevlar.
So with all the shop rental, supplies, and tools you did not have are you saving money over just buying a steel kit of what you are building?
Since you mentioned Atlantic Towers I took a look. Frankly I would do that- it has actual structural engineering designed for significant weight and forces. Your proposed carbon/ foam/ fibreglass composite doesn’t seem to have had any engineering calculations to it, just a guess about what looks right based on no data. Please tell us you have based your design on some data? Other commenters note that while carbon fiber is strong in tension when it fails it can be sudden and catastrophic. I worry about suspended dinghy putting heavy loads on your understrength arch. I am thinking now of that carbon fiber submarine….
Maybe want to wear gloves all of the time when touching carbon or glass... BOTH OF YOUR CHANNELS ARE AWSOME!!! KEEP UP THE GREAT CONTENT :)
Your mold is concave, would the reverse i.e. convex solve your lifting problem?
It’s possible a strand of carbon shorted the heater. Carbon is conductive
I've seen you on a commercial for a knife good going for sponsorship
Really? That's news
Yes let’s gooooo
Nice 👍
Could the shorted heater by carbon fibre bits getting in there?
Just don't imagine that carrying the dinghy on the davits at sea is smart. I have seen many mishaps .....much much safer to carry the dinghy inverted on deck. The davits are still useful every day or on short, sheltered hops....
You guys are awesome! This is an ambitious project with your attention to detail it will come out amazing.
I watched Mike Patey build this plane using similar techniques.

How much did the carbon fiber cost? Just wondering
What about bags of water for weight?
Be interested in how your knockoff batteries perform. I once bought a similar offering for an oldish Dell computer, that I didn't think warranted a genuine battery cost. Damn thing wouldn't even charge properly, after pulling it apart, of the individual cells, half were just cardboard tubes. Pleased to see you've got Festool for the serious tools.
Why aren't you pulling the vacuum down onto the form rather than using weights? Save all those strands (tows) and use them to reinforce corners ect.
I just watched your video and I noticed only one sheet of carbon fiber and if I remember right from a documentary that carbon fiber gets it’s strength from the fibers going different directions in several layers. Also that epoxy will not last very long if it does not flex like fiberglass.
It depends (wrt. to direction of fibers in cloth) on what you're building. For example, if you're making a wing, you're right, you want it strong in torsion (twisting) as well as span-wise and chord-wise. In that case you might (for example) layup the skins of the wing with the cloth on the diagonal - the fibers making X's along the wing to bear any twisting loads. Then lay up spar caps of the wing (which take the span-wise bending loads) using carbon fibre where almost all of the fibers are uni-directional, running the length of the wing and another layup for the shear web (the vertical part between the spar caps) with the strands laid to oppose shear forces between the spar caps.
Or if weight is less of an issue you could just layup the skins in two layers of heavier material, one with the fibers running diagonally (this should be the outer layer of the wing skin) and an inner layer with the fibers running span-wise and chord-wise.
In their case, because the structure they're building will eventually be sort of box-like (the boat being the bottom of the box) they'll get some extra rigidity from the structure itself. (sorta like a how a bi-plane wing can be made stronger than a mono-plane by virtue of the box shape).
Was I the first to subscribe, the 1 popped up !!! Great Stuff !!!
Not sure how much of a pain in the a$$ this is but can you add some of your fav builds your other channel? Really love watching you guys and wish you both all the best!
Not sure what you're asking?
I think project Farm did that product review already.
I have no game against project farm, I love that channel lol
I didn't realize Jade is a lefty lol
👍
Enjoying the videos, but the music volume is annoying. I don't know if you can change it compared to your voices easily. I have to turn you both up to hear what you say, then the music starts mind cracking loud. Yes, I'm old, lol. Hopefully you can make the music much lower than your voices, and viewers can turn it up if they want to.
