It's easy to compliment Matt on his work and explanation of his reasons and method but here's a shout out for Janneke and the superb job of documenting this project. What a great combo.

[@lincolngrove2808]

PS. Nice to see the Ween poster in the workshop too, great band.

[@youngbarnacles]

Great job! Thanks for the shoutout in this vid too. It's great to know that you've got some value from our content 😁 Keep up the awesome work 👍

[@TheDuracellProject]

love your show!

[@newzealandfromadjimini2cor452]

I also watch the Sampson Boat Company Tally Ho build and it is fascinating watching the difference between the modern technical build here and the old woodworking skills on Tally Ho. Good morning inspector you are obviously happy with the work judging by your happy state of sleep. 😊

I’m up-to-date!!! I’ve been binging for 2 weeks from episode 1 til now and now I have to wait a week for the next video! What a PROJECT! Your level of craftsmanship and persistence is super! I’m not a sailor, but I’ve dreamed of sailing and building a boat my whole life. I’m 66 now, so, it probably won’t happen, but it’s so good to see a young couple working hard together to make their dream come true. Keep up the good work! I’ll be watching!

A lot of work, but they’ll be hell for stout! I could have used your Mom’s help when I was building boats! Right on Mom!👏👏👏

[@jimdinwiddie4837]

Having worked structural repair on military and civilian aircraft for 47 years my last 20 years consisted of bond work. When we laminated multiple layers of fiberglass or carbon fiber, we would "debulk" between several layers to remove any trapped air and remove excess resin. That's something you might try on any future layups. Someone mentioned their concerns about the bond between the chain plate and the hull. Anytime we were attaching two precured parts as important as these chain plates it would be with a structural adhesive to insure a good bond and never a cold bond. Just food for thought.

[@soylentgreen326]

Or layup the last few layers and instead on vac banging to self, vac bag to hull, that might work ?

[@tommcintyre5608]

In the cycling industry this is known as OCLV. Optimum compaction low void

[@DaEVOthefreak]

I see it exactly the same way

[@philareilly]

What’s a cold bond?

[@evangatehouse5650]

This is true but Matt did do the laminate in several groups. Did you mostly work with pre-preg where de-bulking is even more important? Yes we will be using a good structural adhesive to stick to the hull. Not sure what you mean by a "cold bond". Will not use hot melt glue :)

[@martinbeaumont1135]

Good shout out to Shane from @youngbarnacles - it's super interesting channel on the technical side of composites. As for the weight diff between your old s/s and carbon chainplates - just crazy!

[@truesdel]

I like the music you use to accompany your videos.

[@glennimmortal]

I built carbon masts in NZ in the early 2000's Awesome note about peel ply bonding I've seen so many videos saying no need to sand if it's got peel ply. We tested this for delamination it's very strong in sheer but horrible in tension 100% the delamination point in about 15 tests funny enough were testing chain plates, your plates are overkill but not the strongest way to build them, still you can sleep well. Love the project cheers Glenn ps if your channel blows up maybe consider building a carbon mast have not seen and decent video on that.

[@TheDuracellProject]

yep, they're definitely over built. Building carbon masts sounds like a fun project.

[@MikeC19100]

That’s a whole lot of layers for those chain plates. It’s amazing how strong they will be (or are) if only one could lift the weight of the boat. I really enjoyed the music you played while you and your mom were laminating the extra layers on the vertical chain-plates. It brought back a lot of old memories and I found myself humming along with the video without realizing it.

[@markp99]

Curious how you will attach the chainplates to the hull. With the massive glass base and the 30 layers of carbon fiber, it seems like a "glued" interface between these will be the weakest link. Any other mechanical attachments planned?

[@evangatehouse5650]

Nothing mechanical. Epoxy adhesive + more overlaps of e-glass. Also will have huge safety factors. A few linear inches (along the chainplate length) of the glue bond is about equal to the wire breaking strength. We have more than a few inches....

[@pkpsail4441]

@@evangatehouse5650 Was wondering the same about any mechanical attach. Are you also milling away material for the toggle?

[@evangatehouse5650]

@@pkpsail4441 Just cutting slots (probably with a hacksaw to disturb the laminate the least)

@@evangatehouse5650 is the differing TCE between E-glass and graphite fiber a problem at all on such a long chainplate?

Hopefully they will keep the big stick up and secure always!

[@jimmyjohnstone5878]

Here in NE Scotland, on the North Sea coast, it's definitely a place where wearing the correct clothing is vital to accommodate all the weather changes in a day. The laminated chain plate design looks great. I wouldn't have guessed at the possible weight saving from a steel equivalent.

There is nothing better than a sunny spring day on the west side of Washington. You can’t beat it. Then the mosquitos. Be in your neck come Friday. There’s a drive in movie theater and it’s not a rip off snacks are not $$ either. Grew up on lake Washington and there was a concrete sailboat very close in 70s I thought that was the silliest thing ever. The Boeing military hydrofoil bout 35 ish feet long lifting out of the water was the coolest thing ever.

Now, I am an OLD geezer, and when I heard the Norwegian being spoken after (in my case) 69 years it took me way back to my best friend's home in 1952. Johnny's grandmother lived with them and when she scolded "Yahneeed!), she'd lay into him with that high pitched scolding and he'd cringe. I never knew what she said, but, Lord love a duck, she got results. I had totally forgotten her, so, thank you for bringing those memories up from deep in my Teflon lined memory bank.

The caul answered a question I was going ask about the first set of chainplates. I may have missed you mentioning the cauls in last week's video. Thanks for the video.

[@imusuallycorrect]

Awesome job! I've made lots of race boat chain plates and one of the worlds largest yachts. Very impressed with how much resin you are taking out under the plastic. As they said when I was learning, pull it off like you're pulling me off your mum! 🤣

[@imusuallycorrect]

Only thing I would suggest - you see when you pull the vac down and the breather is saturated quite quickly. Once it is saturated it looses it's ability to compress - can't compress a liquid - and air to travel. You could put a length of spiral tube to help maintain the vac across the bag.

[@Twelvestonestacking]

Go mom , go Mom...you guys work well together! Goodonyas!

[@MrTremors1]

I was wondering about how the thickness would change the shape of the chainplates so I'm glad you showed that part. Awesome project!

[@capthawk57]

The strength of carbon fiber ONLY is realized when the composite is cured under high pressure and temperature in an Autoclave. Without the Autoclave it is just a slightly stronger fiberglass part.

[@rollinrock6696]

Very good

[@ATAP...AnotherTime]

The weight difference just shocked me... Great job you guys. Another Time Another Place 🐕🐈😄

[@LeftFlamingo]

Good emphasis on squeezing out the excess epoxy. Matt's point is of course one important one. But another very important point, especially with carbon fiber (but other cloths too), is that excess epoxy is heavy and most importantly, brittle.

[@TPLeary]

I agree with all of your “Least Favorites” instead of DH’s I call them “Richard Cranium’s” My least favorite is fog.

[@videotrexx]

Janneke is 110% correct about the weather; I hate it when it's hot and humid while many here complain about the winters (central NY). I say "you can only remove so much clothing during the summer, but you can always wear more during the winter". Funny thing is, the winters here are nothing like they used to be when I was a kid (over 50 years ago), a lot less snow these days.

[@Liofa73]

8:39 -- Looks like you have some delamination between the two folded stacks near the wedge. Is it still in spec? I guess if it's fine, you'll need to fill that to avoid further delamination in service.

[@RebuildingScotland]

I don't think, in my humble opinion, that it would affect the strength in any way. The forces are acting along the length of the assembly, and if 6 layers can support the weight of the hull, then (I forget how many layers in total) will definitely have an enormous safety factor. Then, consider how many chain plates there are in total, I think it'll be okay! The sailcloth will fail long before the chainplates fail.

[@hanfordcreek5309]

To be fair, a lot of the weight of the weldment was for distributing the load to the knees, which you have accomplished with multiple layups in the hull where there was once foam.

[@evangatehouse5650]

He removed inside skin + foam, then added more layers. Probably net weight addition was in the 5 lb range.

[@rjnerd]

I am curious, with all the fretting about correct wet out on the carbon, why you aren’t using vacuum infusion of the resin. The last time I was in a pro composite shop, they even used it on stacks of carbon to lay up wet. (Custom composites in Portland Maine, builder of hull molds) For those not in the know, with vacuum infusion, you lay up the cloth dry, and add in an extra tube at the end of the bag as far as possible from the vacuum port. Fold it over to close it. Pump the bag down, stick the tube in the cup of mixed resin and open the tube so it sucks the resin in. When the resin gets to the far end, crimp it closed. A bit of a trap in the vacuum line will keep the pump resin free.

[@TheDuracellProject]

infusion is a little outside of our scope. you have to use a specific kind of resin for infusion which we don't have and can't afford. maybe we'll do it in the future.

[@rjnerd]

@@TheDuracellProject thanks for getting back to me. I didn’t realize it took specific resins. What is different about infusible resins? It really seems a lot easier, I always thought the reason it wasn’t more widespread was that most don’t have the vacuum bagging gear/peel ply.

[@kennethpaladino4948]

Hey Matt, U & ur mom could start a fibreglass company! U 2 work so well 2gether! 👌❤️

[@Tomm9y]

As these are such vital pieces of the boat would you consider making a few control pieces for each batch? This weight saving should help balance the interior and coachroof alterations.

[@TheDuracellProject]

the chainplates are so overbuilt that I don't feel it's necessary. There's also been enough testing of these materials already. If I got 1/5 of the performance that I expect to get, they'd still be overbuilt.

[@flossey100]

I didn’t understand the diagonal chain plate construction…..is the bias cut on an angle ? Great work and don’t have a boat but very interested in good honest work. This modern process reminds me of old blacksmith springs for carriages. Probably influenced by Britains carriages getting an airing this weekend.❤❤❤❤🇦🇺🇦🇺🇦🇺

[@TheDuracellProject]

no, the chainplate is at the same angle as the lower (diagonal) shroud. Thanks for watching and commenting every week :)
