Vacuum Bag is Hard. Squeegee is Easy. (it's finally coming together LITERALLY)

Carbon Fiber base plates and S-glass dodger legs!? Vacum Bagging is not our strong suit, but dang can we run a mean squeegee! This is starting to get interesting!

A couple of suggestions I learned the hard way that you may have already figured out: Keep a tube of cheap latex caulk handy when sealing up your vacuum bag. Run it around outside the butyl tape. Guaranteed not to leak. I omit the tape altogether. Those shims you needed to temporarily fill a void in the foam. Use Styrofoam and melt them out later with acetone.

[@patwhite640]

A quick hint... Don't rub it in when you clean. Use a towel/rag folded and wetted. Clean in one direction with a new section of the rag each wipe. This is great for glass and varnish. Great show today!

[@barrycashman7001]

Hey guys, with you constantly going thru good clothing while fibre glassing. I worked in the Caribbean factory in Australia, go and buy yourselves a pair of coveralls (long sleeve or bib and brace), and leave them in your workshop, just wear an old pair of shorts underneath, save on your good gear At the end of the job, just throw them in the bin.

[@blueclue57]

Lots of armchair quarterbacks here. I am just thankful that you are back. Love when Jade tries to get Bret serious and he just gives that little-kid grin.

[@Tillersweep]

I am concerned that the structure might be weak and fail in parallel. The 4 corner attachments will dictate this. Unfortunately, if it fails in that way it will be at the worst moment. High seas in the middle of a storm the traveller will come loose. I hope I am wrong.

[@JHK66]

Did a structural engineer calculate that whole thing and made a lamination plan? Same for the fixing at the boat? Or is that all by feeling?

[@giles-df9yu]

Well I was concerned about the foam board, and would have groved 3/4 bent it to form and filed saw groves to hold the form, but then what do I know about it.

[@gaylacrisler9818]

I’ve missed you! Happy to see your work almost completed.

[@user-lq3ss9xf8c]

As a geeky engineer myself, I was a bit concerned when you mentioned using the dodger as a mount for the traveler. Huge forces at work in that part of the rigging, especially in a brisk breeze. I hope you all did the calculations on those loads.

[@ToddManOut]

Hey Brett, a quick note that your influencer link to the Cuts website isn't complete, so clicking the link in the description only goes to their homepage, not your influencer page, the whole URL isn't hyperlinked. Just want to make sure you get all of the credit you are entitled too before the video is up for too long.

[@ExpeditionEngineering]

thanks!

[@allenclark1914]

Great video, I always enjoy watching your content.

[@grubbypaws3566]

Hello Brett and Jade, nice blog I would like to mention a couple of comments, don’t use aluminium as the metal for mounting the arch, as it will start corroding the day you install it. Did I see you both sanding carbon with out goggles?? If you use peel-ply you don’t need to sand it for the next layer, you peel it off and glue up it helps squeeze out air and gives a ‘keyed’ surface. Love the blog keep going there is a lot to see in the med. 😄👍👍

[@etalon3141]

Thats what I understood, but then again Sailing Uma tried this and it failed horribly. kzbin.info/www/bejne/bpy6kIV_qaiKn7c For them, nothing compared to acetone and then sanding, even if peelply was used

[@TheDailyKeno]

It's a myth that peelply is an adequate banding surface. 80 grit or lower for any structural bond. The peel ply has a low surface energy and transfer that characteristic to the 'molded' surface. Yes it's bumpy, but under a microscope its very smooth.

[@grubbypaws3566]

@@TheDailyKeno Having visited the Grobe and the Diamond aircraft factory here in Europe they only use peelply when making their aircraft.

[@badcat4707]

Okay , the project is starting to look a lot more interesting now that the davits are starting to come together , the video as a whole though could definitely benefit from a Penny & Dingo - Hello , welcome home - cameo at the end of the work day ( guaranteed to boost your likes 😸😺)

[@Gwatson000]

I love your work ethic and that you want to make this dodger/bimini yourselves. Of course you could have it made but where is the fun in that? Having the two parallel risers is twice as strong as one but if you tie them together the structure will be many times more rigid because deflection is proportional to the thickness cubed. (One riser twice as thick is 8 times less prone to bending.) Three or four horizontal webs would strengthen the structure significantly. Vertical webs would be better because they would be in shear and there would be more strength in the longer connection interface. It would be like an I-beam. You have to decide on the aesthetics. Maybe a center web without foam six to ten mm thick. Then cut holes in it to reduce weight and bond it in with epoxy/glass. 6.4 lbs is my guess.

[@chipcleveland990]

It's fun to watch this project come together.

[@garybensel6680]

Love your videos! Don't really know how you are going to build/finish that but be aware water will need a place to drain if you seal it in.

[@shawnmoore9380]

Great job guys

[@jeffensing]

I learned fiberglassing as a kid from an old guy that did RC plane pylon racing. Use toilet paper and roll it backwards across the surface to pick up excess epoxy. Just choose your toilet paper texture pattern wisely! 😄

[@robinsmith9734]

Nice save Jade! Unlike the turbo charger issue we dont want the answer before we get a chance to guess!

[@Kevin15301]

A very telling sign of a strong relationship is being able to work and complete a large, complicated, and frustrating project together. You all get a pass.

[@SirCarlosMusicBMI]

🎉🎉🎉 I’ve got to admit that after watching you kids do this over and over again I still don’t understand how this entire process works. And I’m really trying to learn with each video but I’m still lost 😞. This is really turning into a huge project. But I have tons of faith that you kids can do it. Blessings,Carlos ✝️🙏❤️😊🇺🇸

[@sputterscott4728]

Don’t feel alone…cannot wait to see it all together. My imagination doesn’t cut it! Great team effort you two!

[@philipblauw4687]

7.7 lbs. Looking cool guys. A hard dodger is gonna be a game changer. Can't believe more boats don't offer that as an option with some ceiling glass to keep an eye on the main.

[@1kontrabida]

If i may suggest to add a fan/vent the blows out (add a charcoal filter on the back) and better mask and eye protection. We don't notice there are a ton of very fine particles present in the room and that same particles are the ones that stick in your lungs. Great work btw.

[@CarlSmithAviationBroker]

Something to think about as you two spend time around all these chemicals… there are many diluents to use for the thinning and cleaning of epoxies and other resins. Turns out that choosing these various solvents to dilute or clean all have different levels of impact on your health as well as the efficacy of your epoxies and other glues and resins. I learned that acetone is quite high on the toxicity list and also has a stronger effect on the bonding & adhesive qualities of many epoxies and resins. The good news is that denatured alcohol is the opposite. Much 'healthier' to use and is far less harmful to bonding strength. AND - it's probably the cheapest choice!

[@muskyful]

Exactly ....I use denatured alcohol for most everything.... and only acetone when its a must. Also use white vinegar to clean uncured epoxy from skin, clothing and bath for tools.

[@wr4tune]

Amazing how fast these parts form a solid structure My guess is a weight of 5.8 for one of those legs.

[@colinjacob1702]

So enjoy watching your videos thanks for putting them out.

[@RandyB509]

What are you putting in the middle for structural support? Those are gonna bow in the middle and collapse some square aluminum tubing with a metal base plate

[@claytonhudson3941]

I also like the MCM shirt 👍

[@nzrodders]

Chopped!!

[@gregoryh4601]

How about checking out US Composite Hybrid Fiber instead of Just Carbon Fiber?

[@patriciacrosbie6029]

Could you use webbing as a spacer instead of foam. Webbing would handle more pulling maybe.

[@paulsmith6553]

Will this addition change the profile of Eva to more like a Windelo 54? Also why not wear coveralls when you two are in the shop? Good job, keep going!

[@ThePicklePilot]

[@skullhart]

8.7 lbs. I've learned more about fabricating fiberglass molds in these few episodes than I could ever find on KZbin before.

[@tomatobrush3283]

You should run a plastic tube in the legs to run the wires.

[@badcat4707]

Clever 👍😸😺

[@MrWolfie78]

Hey, just wondering. Could you have put maybe some stainless tubing in the middle of the body to allow you to feed wiring through?

[@nutsandbolts432]

How are you calculating the loads the main traveler will put on the bimini vs how to build it? I want to do something similar on our boat, but picture a gust of wind ripping the bimini off the cabin and watching it all dangle over the water from the boom.

[@superformOG]

how are you going to brace this thing from lateral loads are you going to cross brace it?

[@yhlee9498]

Just curious are you guys going to have some sort of support in the middle? Like some sort of bar or plates that goes in between the two wall inside the structure?

[@robertscranton8293]

You're blowing my mind with all the hard work you are putting into this project

[@DarkSevariant]

I find it eye opening that carbon fiber is just a clothed material like fiberglass, with different properties. All the carbon pieces that I see are solid, so I thought it was created ...magically. Like it was liquid or something, and then heated to a chemical reaction point. It's difficult to grasp, carbon fiber...starts out as a cloth, just like fiberglass.

[@user-sn6xz9tb1b]

Forgive my ignorance but is there a difference between Resin and Epoxy, and if so what's the advantage of one from the other? Or is Epoxy just another word for Resin? I ask because back in the day they were two different things...?

[@robm.4512]

Resin is the generic term. Epoxy Resin, Polyester resin, and Vinylester Resin are the most common resins used in composite layups but there are many other types with widely differing properties and applications. Hope that helps. Cheers, R. 😎👍🍻

You guys really need to invest in some suitable PPE for what you are doing. Please read up on the similarities between carbon dust and asbestos, you are putting your own health and health of any future children at risk. In an environment like you are working in a full face respirator or even a powered supplied air respirator(PAPR) should be the minimum when carrying out any sanding/drilling/grinding of any carbon fiber.

[@robertgarbe6348]

Gee you sound like a health expert, what are you credentials? I am one and have not seen any credential research to back up your contention. What they are doing is creating mostly if not entirely very large not respirable particulate, heck even a N95 mask would be enough. And Carbon fiber is not friable at all, so the comparison to Asbestos is just sensationalism.

Adding glass and carbon in one piece is pointless. Their characteristics are not added, instead the stiffer carbon will do all the work, until it fails, and then the glass will take over, until that fails. Use ALL glass or ALL carbon instead.

[@joelnat]

Glass + Carbon in a resin matrix has advantages. As a former aerospace composite tech, I've seen glass add greatly to the toughness and impact resistance. Which is a likely failure mode for this. (Unrestrained dingy, bumping into another boat, etc.)

[@davidbarnes5953]

I'm sorry, but it's so hard to watch. You're making it so hard. It doesn't have to been. If you want to see glassing difficlut shapes. Look through my Cozy Mark IV build. Hope it would help you.
