if you want to keep doing sheet metal projects, you should really invest in a slip roller for curved pieces and a bead roller for the flat areas to add strentgth
My father had all that stuff. Super expensive unfortunately. I can’t remember what it’s called but it puts “dimples” in sheet metal parts which strengthens the crap outta them. It’s pretty inexpensive as far as I remember. Some sort of stamper/press/cutter that is pretty small. I think Grind Hard has one.
Anyway, they are great for adding strength and rigidity to sheet metal.
@@EdwardMurray06dimple die and a mechanical press I would assume
Aluminum oxidizes
Big sheets that are supposed to hold people and water moving in it need☝️ this rigidity without having extra mass.
Hope they add it to the build, I wouldn't want it it to fail
He has one of the dimple die things, he used it with the V10 M5 motor swap build
I would not marry the tub to the pontoons, I’d cap them and leave a small clearance between them. That structure absolutely will flex
My thoughts exactly eyeballing this. It'll float, but even at 10-15 MPH the water in that hot tub is a Problem. The boat is going to hit a wave and the hot tub will continue forward ripping those pontoons open.
Even if you always empty it, the flexing is real and would still cap the pontoons seperately.
Welding inspector here! For those long seam welds you want to ensure stay watertight, I would recommend doing a dye penetrant inspection or similar surface testing method. That will be way more sensitive than a soapy water test and may find some defects you may have missed. Relatively cheap and quick too! Good luck with the project!
I would have thought any welds made on this would need to be subject to some form of NDT for safety.
@@brummiescotNo Oceangoing or for commercial use, so who cares. And the Williamette is pretty narrow.
@@robertgarbe6348 Coastguard who are tasked with saving asses?
@@brummiescot You have heard of the OceanGate Titan thing right?
That's exactly how we did it at Vigor. I also noticed Oscar is not ramping into his tacks either
I think you should add the nose cones that you removed from the front of the centre pontoons to the front of the hot tub to stop wakes 'punching hard' into the front of the hot tub. This would soften wave impact keeping more water in the hot tub and reduce stresses of impact onto the flat potentially weak front of the tub.
This
Also, that might reduce any turbulence/ drag (of that's the right words for that)
Why not go one step further and just add a "boat like" (aka a triangle) piece to the front to help cut the waves?
Yes. Anything that will diminish the brunt force of waves on that Jon boat front will be better.
Blunt nose like they have is definitely going to be bashed by waves and break welds. Not to mention I really think maneuvering is going to be diminished a ton.
the hot tub should be a huge drag on your speed. The pontoons knife the water. The hot tub will plow water.
Nothing that a few hundred more hp can't handle 😅
Not just that flat front but the flat bottom will create suction, slowing it down.
He's gonna need a mid mounted outboard engine on the back of the hot tub like a long train with multiple engines throughout it's length. 😂 It's going to be a self-powered pontoon barge. I can't wait to see it's bow wake.
The amount of drag is going to be like trying to race a semi truck with a full load. The shape isn’t half as bad as the weight of the water on the front of the boat. The pontoons normally sit mostly out of the water. The water will want to sit at water level. I don’t think the two pontoons on either side of that giant hot tub are going to pull it out of the water. Was a miniature model used to test this? Or an engineer? Hopefully I turn out to be the guy yelling at the wright brothers that it’ll never work. I really love the idea so I hope I’m wrong.
I was going to suggest to add the cutoff pontoon noses from the other tubes added to the front of the tub - would help with some of that drag, and would also give a cool look to it.
Maybe add a watertight baffle inside the tubes before you weld on the hot-tub, so if that weld joint does fail those tubes don't fill with water?
i was just going to say that he should weld that separately of hot tub wall, it would be less troublesome to weld it water tight that way and stronger.
Great idea!
I was thinking the same thing.
Having separate watertight compartments worked for the Titanic.
They already have baffles, check previous episodes.
Looking great! If you haven't already welded it, you may want to cap the center pontoons and pressure test them before attaching it to the hot tub box; That way, if the weld cracks in the future, at least the center pontoons will remain sealed.
They will definitely crack
After they cut the noses from the center hulls, it LOOKED like there was a bulkhead a couple of feet in. So if/when the hot tub box cracks loos it shouldn't flood the entire tube.
My consern as well
I came here to say the same. Those center pontoons need a front bulkhead separate from the hot tub box. If you depend on the box skin to seal the pontoon, those welds will fail to remain water-tight as the connected unit flexes. Worst case they result in leaks into both the pontoons and the hot tub box.
@LauS0 no they won't
As a Former Naval Engineer i say plumb a pump for the hot tub and basic sediment filter system along with a good drain. Drop in a big fiberglass hottub and flush and fill on the water. Tuck a couple bilge pumps under and a way to access possibly some cool powered deck topper. Flush and fill takes care of most of the nightmares it causes by existing.
Agreed and that’s basically what they do on large yachts that have hot tubs. Fill at anchor or at dock, flush when moving because as you know, the water is going to be so heavy it’s going to possibly make this boat notable to be piloted and at the very least the water will splash everywhere.
@@WeTheDylan usually flush and fill at anchor, dock water is narstyyyy stuff
agreed. or just make it a moon pool! save a ton of unnecessary weight and could still add heating elements if you wanted and a net to keep out fish or debris
so much this.
as a former naval engineer you should be roasting the shit out of the hydrodynamics of that hot tub & how its going to push more water than the daily tide 🤣
You should probably create a point on the front of the hot tub to push water around it, instead of a water plow in front. it will help with directing the water around for better flow dynamics and wont try to sink it like if were just one single blade pushing the water, but cutting through it. kind of like the front of most boats..or the front of the pontoons for the same reason. Especially with that much weight in it will be a plow in the water. Stringers underneath the hottub down the length of the pontoons probably would not hurt. This would probably help structurally as well with the weight of it all. just my thought on it.
I hope you have a gantry crane to drop the hot tub down into the box. They're stupidly heavy and awkward. Also, I don't think it's a good idea to weld the hot tub box directly to the center pontoons. Wont the mass of the hot tub flex and crack those weld joints? Maybe cap the center pontoons and keep them separate from the hot tub box.
That was my thought. I was surprised to hear him plan to direct weld them.
Watching the expansion and contracting of the aluminum in real time was fantastic
not being a marine engineer but my gut feel is the hot tub box being sunken is more hassle than its worth. I imagine the purpose of pontoon boats is its a low drag profile in the water that wont plain as such like a flat bottom boat. The big box seems to sit lower than the pontoons so will require a significant amount of power to plain. The sheet metal thickness is fine in my opinion from a structural perspective but fatigue when subjected to repeated slaps by the water pressure on the outside will fatigue the focus points (corners and flat surfaces that flex on the intersection with a rib) purely my perspective as a time served mechanical design engineer. But as always loving your work
This build feels closer to a house boat than a yacht.
It's already a thing that exists, it's called a party barge
Chris, in order to strengthen the large surfaces you can use a bead roller to roll a bead In them.
Crosses work very well.
B is for buy everyone a life jacket.
Man I wish I could find an employee half as good as Oscar for my business he such a good worker
He's a good dude.
He makes this channel
Better have deep pockets…Chris is paying him or sharing revenue quite well no doubt.
Oscar isn't just an employee, he's obviously also a good friend.
Banding occurs when the refresh rate of the LED is different to the frame rate of the camera. If you can change the camera frame rate to match the refresh rate you should eliminate the majority, if not all, of the banding. Make a couple of tweaks there and run some tests, it should help greatly.
timelapse cameras dont have frame rate, but ive worked on it and i think ive got it fixed!
@@BisforBuild thanks for the info, I'll do some research and learn some more. Fingers crossed it's sorted
It’s not the framerate, it’s the shutter speed. They are different. You don’t want the shutter speed to match the LED refresh rate, because the shutter will “open” either only while the PWM controlled LED is on or while it is only off. What you want to do is set shutter speed to something >2x slower than the PWM frequency of the led. This ensures light hits the open shutter no matter what phase the PWM sync is at. The banding is due to the camera having a rolling shutter. Even digital cameras have a rolling shutter, global shutter CIS sensors is usually high end.
@@acreery1 yeah I realised I said frame rate a lot and absolutely did not mean that, I definitely meant shutter speed but I'm tired and my brain isn't working right.
Thanks for the information though, I'll make a note for future
@@TotallyNotRoadkiill haha, no worries!
That's the largest beer cooler on a party boat that I have ever seen!
The volume of that hot tub is greater than the volume of the pontoons that are supposed to float it - just look at it. I see lots of foam blocks in your future to make this float with water in it.
people worrying about how well it's going to plane, i'm over here wondering if it's going to float long enough to find out. and how long it'll take for the weight of 300ish gallons of water plus the hot tub itself to tear out the welds on that thin aluminum and flimsy 1" square tube.
Im pretty sire he did his calculations wrong by saying the hot tub will add Buoyancy. It will not. It will be a neutral object for the volume of water for inside the hot tub
@@justinhowell8484 the only neutral bit of water in the hot tub would be the amount below the plane of the water surface he's floating in. and if he did try to make plane with this brick, the amount of neutral weight shrinks as the tub rises out of the water. this would effectively make the hot tub heavier on the nose as it went.
It will certainly be neutral when it sinks
It feels like it's gonna snap in two at the first wave the boat runs into
fellow Oregonian guy here, good luck, and these comments are brutal.
Hello great videos. I would slide the hot tub back a few feet and put 2 of the pontoon in front of it so that would take the hits of the waves. Not the hot tub frame.
We live and we learn, whether its a success or a fail learning is occuring. I am neutral in the project since I have no boating experience or boat design experience. I'm here to watch creative minds bring an idea to life. Thats more than most people.
Looks Like a expensive mistake 😅
Good luck ❤
ikr he couldnt even keep a pre built yacht above water so this will be interesting
he doesnt even have a way to haul it yet lol
It may be the first pontoon submarine.
I think you should have left the bow point on the two middle pontoons and stuck the hot tub on top of all four pontoons . That way you’d have four hulls of buoyancy to counter the weight of the tub . This looks to be very nose heavy and will perform like a Mississippi barge and no amount of power will make it plane
Just can't stop thinking about the possibility of the pontoons snapping in half.. I'm trusting the process, tho!
The problem is the pontoons will want to displace the water and sit about 50% in the water. That box without a V hull will want to plane off out of the water 100%. As designed the boat will porpoise in and out of the water
i disagree, i think itll have enough buoyancy itll plane across the water
There will be no plane with this huge contact surface (hottub box) touching the water! Unless you plan to mount a rocket to it 😅😅😅
It might plane like a flat-bottom airboat. I'm trying to envision the effect. Either way, it's an entertaining build.
@@kdwalker1656 A flat-bottomed airboat has a much flatter slope and smooth transition than this triangular box with a very steep slope.
@kdwalker1656 that's my thought, the problem is that will raise the pontoons out of the water in the front. It will definitely ride nose high
I am no boat expert but is all the weight in the front really ideal? Did they do the weight calculations?
None of the water below surface level will weigh anything.
@@Grunk-ik9osif it’s going to plane out the water in the tub will all be above the water so it will be thousands of lbs of bow weight making it bow steer and plow
@@jaydenbankes8126 I can't imagine this thing going to be fast enough to "plane out of the water". Is more a mobile pontoon than a boat.
@@framegrace1 His plan is apparently for this thing to plane according to his other comments... This thing will likely be a failure, but im still gonna keep watching lol.
Can't wait to see the aluminum lift 2 tons out of the water under stress. Better have the coast guard on standby if you are going to try it.
The hot tub will be pushing water even though it has an angle on the front side. It would be more aerodynamic to have the angle rounded(radiused) on the bottom front of the hot tub. As it is, there will be a lot of cavitation created there that will interfere with the props on the engines. I would not weld the hot tub to the center pontoons. I would put the nose cones on the front of them or at least cap them off. If the boat flexes or hits an object in the water, it may break the welds at the hot tub, flooding the center pontoons. That is just my opinion.
Interesting to see the engines going on this. B is for Barge.
Can’t wait to see how you insulate the hot tub. Whatever water the boat is in is a giant heatsink for the hot tub. Will be hard to have more than a “slightly warmer than the river” tub.
Now that’s what I call a big live well.
If those super-long aluminum tubes don't crack apart or leak at the seams as soon as you plunge through a big boat wake, I'll be astonished. They seem a bit fragile given their extreme length for the forces they will encounter. Love the videos!
Damn Oscar gets treated like an old work horse on a job site.
A four person hot tube is about 400 gallons of water. Thats 3,350 pounds of water that should be in the middle or back of the boat. Ever been in a cruise ship pool?
I was thinking the same thing -- Search pontoon boat hottub, they're always in the middle of the boat.
I agree,definitely going to be nose heavy by the time you put 4 fat chick's in it lol.
where in the world did you get your 400 gallon spec? I have my hot tub already and its 222 gallons
222 Gallons is 1,830 pounds. The thumb nail looked like a four person tube to me. But still that's a lot of bow weight with water in it.
he cant even keep a pre built yacht above water, are you surprised
I think you need a structural bulkhead between the hot tub and pontoons - something for rigidity. Looking awesome! Cant wait to see it sink, .. . .. I mean, DONE!
Definitely sink 😂
They'll float-test this before adding furniture and stuff, right?🤷🏽♂️
Man that is nuts! what an awesome build. very interested to see this thing finished and on the water. can't wait!
Gotta respect the amount of effort and creativity. Will be watching
Awesome and outstanding content.Thanks for sharing and taking us along
This thing is so cool! Can’t wait to see more.
Kudos, BIFB crew, this project is awesome and y’all are fearless! Love it!
Guys, please weld in a separate end cap for those inner pontoons. Their integrity is more important than the whatever weight or money or time you're saving. I'd hate to see this beast sink because of a small oversight.
You might want to think about storing your spools in an airtight box and evacuate it with a vacuum pump. Then fill the box with Nitrogen. They are oxidizing, not getting old.
Love your videos chris!!
Are you going to fill the floor and sides with floatation foam for insulation so you can keep the water in the tube hotter easier.?
instead of the hot tub under the boat, use your two extra pontoons to make four total long ones. then have a hot tub mounted on the deck. that way you dont have to deal with all the structural and hydrodynamic issues that others are talking about
Future episode- 'My giant hot tub sank my giant yacht'.😂
Looking forward to the finished product
you should cap the center two, just in case leak
This thing is wild! 🤘🏼
Thank you for all the hard work in making these excellent videos.
It's going to be incredible!
I have been building kayaks and boats for years and what concerns me is the slope of the tub. You are going to be pushing a lot of weight of water. You might want to increase the slope or use the front bows that you cut off to improve performance
I agree! The style is like an airboat, but the slope is way off! They are way more "pointy" and have a long smooth transition from slope to flat, whereas this just angles to flat.
The bottom needs to have either more supports or needs to be 3/16 or 1/4 aluminum
That is a very vulnerable section of the boat !
Very interesting build. Its going to be fun seeing the outcome.
There sure are a lot of people making suggestions about the design.
I can’t figure out why the hot tub box is being welded directly yo the center pontoons instead of them being capped and the box separate.
Wow the hot tub turned out so much better than I envisioned!
I’d cut those leftover nose cones and weld them on the front of the hot tube structure. Probably cut the water better than that flat face.
So cool Chris! Great work everyone. Keep the updates coming! Don’t stress too much about the striping, it sucks but we can still see whats going on, thats whats important. If you can fix it great, but not super critical
I really enjoy your videos, this custom pontoon is awesome..
Staying true to "Building!" I love it!
Great project! Keep going.
That sheet aluminum your using for the tub is a bit thin looking theres going to be alot of pressure from the water pushing on it.
They’re putting a hot tub inside of the area they just created no pressure unless your talking about the out side water force .
Physics not your strong point I take it?
I'm an engineer and work with lots of aluminium, the sheet metal for the hotub is too thin which is why it's distorting so much, I would definitely go thicker. The box section also looks way too small, there is a high chance the welds at the bottom of the tub will fail with all the weight. I would suggest welding some gussets in for more strength.
@@MrThisIsMeTooRight back at ya!
shoot.. hope its not to camera thin
I think I agree with the bead rolling guys here. Makes aluminum way more strong but not add any brittleness to it. And it's neat skill. To have
Make sure that thing will fit out those doors!!! Sick build
Can you Bead Roll the sheets of aluminum? That should make it a lot stronger
Indeed B is for build & it's evident Chris loves working with metal, you must love the Cybertruck I guess
Consider building a garage door style cover for the hot tub that pockets under the floor.
Y’all are crazy, I’m a fan of it
I use my DJI osmo action 1,2, and 3 for time lapse and they are flawless
Yacht!?! More like a raft with this huge hydrodynamic killer box of a hottub!?
Sick dude
Banding or no banding I'll still watch and enjoy. You're killing it!
You should make a small scale model and test it on the water
Sweet build
Cap off the center pontoons on the inside diameter before welding the hottub box to the outside diameter. That way it wont leak if the weld between the box and pontoon breaks. And maybe an extra baffle plate inside it too
Having weight concentrated at each end of the boat (hut tub at the front and engines/fuel at the back) could cause a decent amount bending stress on the boat.
I'm not an expert in aluminum, but I would expect that Increasing the length of the pontoon and having a weld/splice near the center could impact the strength of the pontoon. Fatigue near the splice could also be an issue.
Why don't they sell pontoons longer? That was my thought too, as the reason. I thought if you could somehow have them offset and then have them hinge in the structure including the floor it could flex in the middle at least. If it's only small waves in like a river maybe not a big deal.
This is incredible. Don't get me wrong, I love the car videos, they are how I found you, but the boat stuff is so cool. I always wished there were more yacht videos, now I'm stoked to watch everything.
Can't wait for the airplane project!
im scared of flying
Okay then b is for Train? @@BisforBuild
@BisforBuild Think I've had more pucker moments on water than in the air 😂. Not a pilot, but about a million passenger miles.
you have to Face your fears
or forget about it i dont whant you to die It is difficult to find good CZcams channels these days@@BisforBuild
@@BisforBuild good thing you did not win that helicopter then. 😀
With the spare pontoons you can make a floating dock or trampoline to tow behind for bigger parties
look into videos of pontoon boats getting stuffed due to too much weight on the front end, you might wanna relocate that hot tub time machine to the mid deck. otherwise sick ass build dude!
Yaaasss! B is for build!
Ptown!
This is so awesome 😂
Oxidized is the word you're looking for.
introducing impurities into aluminum welds seems like a great way to Have A Bad Time™.
Insta 360 Ace Pro or IPhone works well for time lapse. That hot tub is massive. Loving the b is boat build.
The water coming off the front pontoon cones will be hitting the front of the hot tub hard! Most likely damaging the front at high speeds.
You can buy extra wide aluminum rolled sheet, you have to buy usually 1 Metric ton so if you go into production it's definitely worth it. Especially because at melt volume you get wholesaler pricing.
Cool bbuild!
The hot tub cover could have baffles that drop into the tub when covered (part of the tub cover hinged for flat storage) to handle sloshing when hauling or when boating when not using the tub. Might make docking safer... Just a thought might not be worth doing just excited about the build would love to have a toon for the lake,
You should of built with the front towards the door. That way you could back a trailer under it and pull it out. Right now you have to get it out of the building before you put the trailer underneath. It was so simple and easy. Now you have added a whole new job to the project
im no camera expert but from what I recall the banding has to do with shutter speed or fps in relation to your room lighting leds and such have a flicker we cant see, when that happens
ND filters help this
Insta 360 cameras have been incredible for me and I'd recommend that. You can turn them from action camera to 360 cameras too
Finally, an early SEMA build!
0:28 ❤🎉 Love your content.You know I was thinking with those 2 extra pontoons.You gotta you should make them fold down for side support while on the lake.That way, you can have a lot of people on top and you don't have to worry about tip overs.
Keep the videos you're doing great🎉
Can’t wait to see it on plane with hot tube full! 😂😂😂😂😂😂
No water left in it....
Deck washer 5000!
*tube
It will never plane, wrong hull for that.
I don’t think that’ll be a thing happening.. I don’t even think it could go in the ocean 🌊 it’s going to be a slow and steady process kind of beast. It’s only going to be in fresh still water. It’s in pontoons.
Chris putting some bead rolls in those various panels strengthens them trmendously stops oil canning and with lighter thinner materials as in using Angle Aluminum and C channelo not to mention all the various radiuses imaginable through extrusions , I would build the entire cabin with it inside and out , furniture too plus its all removable , reconfigurable and reusable . you could redesign it every year without spending a dime , a metamorphic house boat that evolves with time , through the use of extruded aliminum for that minimalist sustainable bamboo type finishes .IKEA type stuff , tough durable lightweight modern timeless. but sticks and plastic laminates will probably be cheaper and easier but you get what you pay for , SOLAR would be my primary theme that and days off grid without the need to dock with full anemnities .
that barge is going to plow a lot of water:)
To help keep the water in the tub I would put a rolled edge all around the tub so when the water tries to escape it will just flip right back in the tub.
10:17 "lunch time steel run" while building an aluminum boat LOL
I would suggest sealing the front of the center pontoons before you set the tub in. If you just seal it with the back of the hot tub it will be a weak point that could cause a disaster. Also looks more like a barge and you might need a tug to tow it.😃
The vertical banding is most likely caused by a mismatch in the hz of the LED lighting and the shutter speed on the camera, try lowering the shutter speed to somewhere between 1/30th and 1/50th of a second on the camera and it will probably go away, hope that helps!
