How to install plastic frames for traditional wooden boat building (Part 1 of 2)

[@muaddib7685]

This guys boat knowledge is next level. I had no interest in boats until I watched some of these vids.

[@dwaynekoblitz6032]

You explain things so clearly. I deeply respect the talent that flows from your hands. You make it look so easy. You’re an artist. ⛵️

[@stevecarlisle3323]

Louis is a true craftsman, explains what he is doing, and why. I have sat in the same spot, but here in the PNW. I enjoy his video,s and always come away with a new trick!

[@_onesimpleidea]

+Tips from a Shipwright Nice explanation. Although I feel like I'm drowning in terminology sometimes, you do a superb job of explaining, including the terms, in a way that helps less experienced people like me follow your process. Really get a lot from your videos. Thanks.

[@AR1G3]

I like how Louis keeps traditions intact but also isn't afraid to use modern methods and materials, and isn't afraid to sometimes use the metric system. He doesn't seem conservative, which is special for the trade he is in I think.

[@craig5477]

And just when you begin to think you understand how things work you run into someone who truly does, belaying misconceptions & saving myself from once again having to learn things the hard way. 👍

Just finished 9 sister ribs on a 1933 29ft American car & foundry (ACF) cruiser. It tightened up the planks and just about restored the boat to the original shape. I had seen the first video on this method and decide to try it. Thank you for all your video,s.

[@Brian90402]

Was it difficult to do?

[@georgedodd9616]

no, it was very easy, the ribs can be curved by hand or in a vice. you also use a heat gun to bend the rib. I just finished doing 10 more sisters this year approx.1 1/ 2 days of work.

[@brian-nd5sl]

+George Dodd where did you buy your plastic?

[@georgedodd9616]

I got the material from jamestowndistributors.com. it is king starboard polymer sheet and I think you can it cut if you want. I bought the sheet and cut it on a table saw.

[@hogheadv2]

Nicely done, I have used that type of plastic for other things. Never thought about boat ribs. Amazing strong and can take a pounding.

[@TipsfromaShipwrightvideos]

hogheadv2 Sure does.

[@richardbohlingsr3490]

Nice job on the planking.

[@Tshade67]

I have been enthralled by your videos! You knowledge and skills are outstanding, and the quality of your videos is top notch! I've been building, restoring, repairing automobiles for over 30 years, never been interested in water going vessel until I found your channel. Maybe I was a shipwright in a previous life?

[@briansb2455]

I used this method to replace/sister 15 ribs on a 36' foot sailboat. It saves you tons of time and money. Sledgehammer the HDPE frames into the bilge. The modified C-Clamp is an excellent tip. You may read naysayers and skeptics about this technique. Just ask yourself if you think the Naysayers know as much a Louie. HDPE is insanely durable stuff and perfect for this application.

[@luckygargoyle4881]

I can see the tear out if you didn't use it. Definitely a time saver

[@kz4506]

Plastic frames with a carval hull in a big sea and stiff interior framing I can see the planks moving to pressure from sea And the calking opening up as to stiff timber frames keeping the form in align as it was designed for ,pdfe is different

[@guyvangenechten6484]

Very impressive !!!👌💯👍

[@Hennessey_and_smoke]

Seriously, thank the sea gods, people are moving away from wood in traditional boat building. I use King starboard for everything now. hdpe is the wave of the future in keeping these boats alive. It makes me such a huge fan of Louis.

[@baltsosser]

U. S. and British Navy still have wooden boats, floating and serviceable that were commissioned before the U. S. was an idea, let alone a nation. It is technique that still has a strong place in proper construction of a boat.

[@IandiBoats]

Great video. Where are you sourcing the Doug fir. It looks like really good material

[@oldtoby8279]

This video really inspired me. I'm getting a parrot!🤣

[@tomhutchins1046]

have you considered King starboard? Its simular to Hdpe but a little harder and has UV protection. Most HDPE does not and the sun will break it down pretty quick

[@symbolsandsystems]

Can we get a video of the new boat construction that uses these materials?

[@bobd.]

Teach me to build a boat. I would be thrilled to apprentice under Lou if given the chance, just for a year. I don't even need a salary, just give me a job where I can learn. :-)

[@RaySmythe53]

Louis, I've seen you scarf boards on boats twice now. How do you ensure you're getting the correct scarf angle on both boards without removing the original one. Thanks!

[@bg147]

That was some nice douglas fir. I wanted to replace my porch with quarter sawn but it costs a fortune today. So, I just rifled through a hundred pieces of it at the Menard's and found a few that had vertical grain to replace the damaged ones. The other boards are staying. They lasted close to a 100 years and will probably go another hundred. Most people tear it all out and lay down pressure treated southern yellow decking with gaps. That stuff is just bad and is no substitute the old tongue and groove fir.

[@cadenaek3066]

I am pretty sure you can still buy handbook with all details you need on stodoys.

[@swirlingorlando7535]

Yes. I love that !

eminently sea worthy as always

[@Odocksailing]

First off I have never built or repaired a wooden boat with ribs so the use of plastic ribs has blown my own assumptions of the purpose of the ribs. It seems that the plastic rib would want to straighten out so the shape of the boat is maintained in large part by the deck beams fastened to the fore and aft beam at the gunwales. Sorry I don't know the correct term. Is that right? These ribs are not attached to the old ribs either so the old rib can't help hold the shape of the new rib. Can you explain what ribs actually do structurally please. I thought I knew until this video. Thanks Louis so much for sharing your knowledge.

[@Project_Prescott]

The Finast Kind II is docked just down the street from my house

[@lamontcranston8181]

So how can this stuff be easy to bend yet maintain the rigidity of the boat?

[@Damian-Church-NZ]

Anybody know where it can find this HDPE? I can only find thin sheet.

[@Knoar]

Is Portland waterproof? I use Sika-Flex to protect the bolt heads and washers.

[@shanebba2]

hi Louis I want to modify a sailboat using recycle plastic. I am a shipwright wanting to experiment with recycled material. wouldn't it be great to use recycled materials to build boats. have you heard of anyone who has tried this. love your videos

[@Rickmakes]

I noticed the use of flat head screws. Are those all hand driven?

[@scotyfilms]

Thats funny. Out west the ribs usually go from the deck down under the covering board by a foot or less. It looks like this boat, it's the bend that goes bad. hmmm.

[@adriansmyth9806]

Sweet Louis, you're the best. Build me a boat willya?

[@louisdrago3861]

Adrian Smyth )

[@GoofieNewfie69]

Interesting technique , why use bronze screws instead of stainless?

[@TipsfromaShipwrightvideos]

All the fastening in the boat are bronze and they will outlast stainless.

[@GoofieNewfie69]

Tips from a Shipwright Interesting, I would have though 316 SS would be better.

[@seancook2331]

If i watch all your videos, do you think i could build my own sailboat? lol, i havnt had time to watch all of them, but you do really good videos. Also i was wondering what kind of wood is good for boat building and does it grow in Florida? hehe

[@luckygargoyle4881]

when oxygen is removed from stainless it corrodes and pits. So SS above water level and Bronze below or just use bronze

[@151manasa]

can I use the standard HDPE for framing my 30' catamaran?

[@MrAluminox]

NO. none HDPE. It's has a too low modulus and a very bad ratio strength/weight. And it's impossible to glue. It's just good to keep an old wooden boat in one piecer.

[@TipsfromaShipwrightvideos]

+Ilan kzbin.info/aero/PLzlN3A2DLgNwWFZPXuH83wDY95x3FPdgD

[@MrAluminox]

Thanks for the links. I love your vids as you have a very pragmatic approach. I know HDPE and also a bit about boats and ships as I'm a retired naval engineer. I was trained and became naval carpenter and loftman in Sweden and France in the seventies, in classic wood and epoxy wood composites. At the end of the seventies I returned to school and became naval engineer for the French Navy making several ships around 150 feet long in sandwich cold molded wood and foam, sandwich GRP, carbon fiber nomex pieces, alu and steel. I ended my career as structural engineer in composites and worked on the structural calculations of several racing trimarans made in carbon fiber. Now I take care of my orquideas. Coming back to HDPE I answered for a catamaran framing. Generally wooden cruising catamarans are made in thin skins of plywood around 1/2 inch all glued and screwed on a rather rigid transversal and longitudinal frame of light soft wood stringers and plywood or wood laminated ribs. It's imperative to get the best ratio rigidity/weight possible, catamarans have enormous surfaces but must be kept light, and you must absolutely glue if you want a good transmission of the stresses from the skin to the frame. It's a structural system similar to the wing or fuselage of a aluminum riveted plane. HDPE has a density around 9.50 gr/cc, almost twice the density of a spruce or an okoumé plywood. It has a rather low rigidity ie low modulus, you can bend easily by hand a 2X2 inches section (you won't bend easily a 2x2 piece of spruce) and it can't be glued, so it has nothing to do on a catamaran which has structural requisites very different from a classic wooden boat. HDPE has perfectly its use on a plank classic boat as often high density hard woods are employed, weight is not a priority, and the planking has rather generous scantlings. The structural problem is very different from a catamaran structure. Making a very caricatural picture, the main problem is to keep the planks together in a way that the seams won't open and spit the oakum. Sawn ribs are the weakest structural part of a classic wooden boat because of the wood grain, So for doubling the ribs HDPE has very good qualities. Not too heavy, no grain so no splitting, easy to work, cut and shape, grabs the screws and keep the bolts, no need of finishing nor protection, it won't "eat" the screws like acidic woods do, has no electrolytic problems, it is resilient and ot is largely strong enough to keep the hull planks aligned and fitted together so global rigidity is improved. And I almost forgot not too expensive. Lone con it's ugly, or better I would say I need to be used to the color. I'm not a purist integrist of wooden boats with 12 coats of varnish. And conscious of the problem of cost, I made working and fishing boats (racing trimarans are working boats not precios pretty varnished yachts). I hope my english was good enough to make an understandable comment.

[@ronlister4033]

Great job.

[@Brian90402]

Where can I buy this stuff? The sites I found only have 5' lengths.

[@sp10sn]

Did you ever find a supplier?

[@CROSSAWGA]

Louis, Your knowledge and ability is amazing. But a question? Why don't you use Southern Live Oak? Steve Cross

[@michaelflynn6178]

Very interesting Thanks

[@junkmail4613]

8:40 Progressive bevel sawn the first deck piece to what seems to be a sidewall(that you seem to be calling 'the ceiling") I would like to see "how you patterned it" made "the angle of one piece to exactly match" the other, I would much like to see that "demonstrated". Is there a way, that you remember "where in your vast videos" that you showed something similar, that you (or one of your viewers ) could point me to, where I could see such work? (see how to do it just below) REFERENCE: If one goes to the video where it is shown, and "right clicks it" and selects "Copy video URL at the current time" and then PASTES it in their comment, like this: kzbin.info/www/bejne/p6jZiH6EjamHl68 , then if I was to click on that hyperlink, it would take me right there to that video, at that precise second, and start that video right there. ANYWAY, I would greatly appreciate that reference. Thanks a lot. JUST FOUND PROGRESSIVE BEVELING at kzbin.info/www/bejne/Y6XCqGZuorhsmNE ALSO, HERE'S ANOTHER : kzbin.info/www/bejne/f2W6mGVni5qDpLs ----- Really good stuff, both! (also I'm impressed you selected the growth rings to be perpendicular to the surface of each of the two pieces of wood, to minimize expansion/contraction of the proposed glued joint )

[@flyfliker]

fascinating

[@chuckmesec]

Thanks for the videos. I am currently restoring a 1939 sloop and am wondering where you purchase the high density polyethylene?

[@charlesreeder2594]

Do you have a link for the supplier of the polypropylene.or can you post their contact information? Thanks

[@fayzemourie7776]

MR SAUZEDDE I LIKE THE USE OF PLASTIC IN WOOD BOATS FUTURISTIC BOAT BUILDING AND TECHNOLOGY UNDERSTANDING - FUTURISTIC S LOOKING BOATS FAST BUILD BOATS WILL WILL INCREASE FUTURE BOAT BUILDING TECHNOLOGY IN GENERAL MAY BE PASSENGER BOAT TECHNOLOGY BUILD FROM WOOD AND TIMBER PLASTIC AND MAY BE STEEL ATTACHED MIXTURE OF GREAT EASY TO USE AND VITAL TO COST IN FUTURE BOAT BUILDING AFFORDABILITY TO BUY SAFETY

[@brian-nd5sl]

where'd you get your plastic?

[@richarddavies-scourfield8413]

There's some interesting stuff here. The boatbuilder says he has done many vessels with this plastic and I assume it has US Coastguard approval. Seeing how easily he bent the plastic frames is a little scary. The original frames (probably oak or rock elm) would have been MUCH stiffer than the plastic ones. So, the question is, how has the structural integrity of the hull been affected? Surely it has to be more flexible than the original. Thus, if it is moving differently something, somewhere, must be more stressed that the original design called for. Brilliant idea but tensile and flexural properties very different from wood. At least it will never rot!

[@alexnagle575]

Richard Davies-Scourfield Much of the stiffness will come from the outer planking, and since the plastic is sistered in, I imagine that the original frames will help. He mentioned a new construction using the plastic, should be interesting!

[@fayzemourie7776]

✨✨✨✨✨✨👍👍👍👍

[@dudleycampling9355]

Master shipwright ?

[@supurbian]

the problem with that plastic is that nothing will stick to it...you cannot use glue or fiberglass resin

[@marzsit9833]

you wouldn't want to anyway. fiberglass has no place in a planked wood hull, it's ok for decks and cabin tops but that's all.

[@figueredoruley8050]

I did it too. This is what I used Woodglut designs for

[@mgmoody42]

You'll have the devil to pay! (Now to find out who knows of what I speak of.)
