$100 Homemade Kayak 

My first time Kayaking and this Kayak held strong. ru-vid.comUgkx4k5UrhC3v_Y4hIEaXLGvHcN5a5aBmZNB The water got pretty rough as a speed boat zipped by me, and the Kayak withstood it (I expected to be capsized). The Ores are very easy to put together, the pump worked beautifully. the seats are a bit hard to sit in after a while (I recommend sitting on the floor). after reading the reviews I was very scared it'd get a hole in it, the material is very strong and durable. The Air valve may need a small Phillips head screwdriver to adjust, other than that, it's well worth the money!(update)I've gone Kayaking in 3 Lakes and 2 rivers totaling about 40 miles. the kayak had two holes and they patched easily and no other problems can't wait for kayaking season this year!

If the pvc is sealed, it doesn’t need foam. The foam is just extra weight. Air weighs less than foam.

When I went to high school I had to take geometry as one of my math classes. Using the volume of a cylinder will tell you how much weight your kayak will float. The wood touching the water floats by itself so you could basically call that a neutral weight, but the materials above the water level all count as weight along with the weight of your pipes. So you have 4" X 120" pipes. V=Pie times R squared times height so you have 1507 cubic inches of volume per pipe or 3014 cubic inches in them both. A gallon of water is 231 cubic inches so your two pipes displace 13 gallons of water. A gallon of water weighs 8.35 lbs. so your 1st effort kayak can effectively float 109 lbs. Volume displacement is not arithmetic--so if you went to 8 inch pipes you'd have 12,058 cubic inches of displacement and your kayak would now float 436 lbs.

You guys are maniacs for making vids every day in this Texas heat. It's been 🔥🔥🔥🔥🔥🔥🔥🔥

12:58 his example for its gonna float is “it’s shaped like the titanic” 😂

A light weight material you could use for making a cheap boat like that,is rigid insulation foam board. It will still float even if it's punctured. Where I live I can get 8'x4'x4" sheets for little over 30$. Probably need 2 sheets at the most for a boat. I love this kind of creativity! Rock on!

You lost buoyancy when you put all that foam in the pipe. The pipe now holds less air.

Dang, you beat me to it rob and lfg. I was gonna build one of these. Homemade stand up paddle board anyone?

Great video. A thing about the foam. Adding foam to an airtight void will NOT make it any more buoyant. It will prevent the void from taking on water if there were to be a breach, BUT the only thing foam is doing at this point is adding a small amount of weight. Think about it this way; what would float better? A balloon full of air? or a balloon full of foam?

I think i heard that the spray foam will absorb water instead of making it more buoyant. And putting foam in the pipe will only help when the pipe takes on water it is a reserve buoyancy so your just adding weight. Looks cool though.

One more thing, tell your friends from Favorite when they’re doing the dozer work for the lake that if the land has ever been used as row crop acreage to make sure they do a lot of work with a sub soiler. Because if the land has ever had any field drain tile put in it to keep the water drained off of it the piping will still be there. And some of it may still be functional which could keep the lake from holding water. This could be disastrous for the lake if it’s got any in it. The subsoiler will destroy the piping so it won’t drain anymore. Just some thoughts I’ve been meaning to share for a while. Peace

Lfg is so skeptical 😂 he's a measure twice cut once kind of dude. You can tell hes been on his woodworking game. Rob on the other hand is flying by the seat of his pants lol. Yalls different personalities make for entertaining content

Congrats on 1 million

best gift ever for LFG! these flies in texas during this time of yr are the ultimate pest

Awesome Video! Congratulations *Fisherman.* Have a great week of very successful! Hug!👍🎣🐟🐠

Steven was playing with that can, trying to make y’all feel more manly 😂😂

i think leaving the PVC pipes empty would have been much better. And probably put a third one in the middle. Maybe 2 more

Congrats on 1 million subs Lunkers! You deserved it ❤️

"High-speed, low drag..." You just brought me back for a bit. Thank you for your service.

You could have calculated the displacement volume of the PVC tubing. You could then figure out what length or how much tubing you would need (depending on your body weight) to keep you a float. If I'm not mistaken you want the displacement to be 3x your body weight, if you want your canoe to not only hold your body weight but remain floating with majority of it staying above the surface :)

the expanding foam would not help the buoyancy because the PVC pipe is still the same surface area on the outside. If anything, you made the buoyancy worse for the pipes by making them heavier! Still a great video though,. keep up the awesome uploads my man

Congrats on the Million subs n the new book, preordered ASAP.

Even though the boat didn't work out very well I appreciate you posting this it is still helpful for people looking into this stuff.

Gave kayak to subscriber = instant thumbs up

Much safer to just use a notebook and keep in a safe, no website is unhackable! Remember that 👍🏻

Team building skills, squirrel!

Rob: "Its long, its narrow!" thats what she said 😂😂😂 ❤ funny video with LFG

My pipeyak used a bridge with 4 45s Angeled up 4inch tees x4 and a lawnchain in the middle and was much wider and very stable... Very happy with my build

Tip: Hang mesquito attractant on bug zapper, and set away from patio.

15:30 to skip the time wasting. Spoiler, it doesn’t work

Lmao hit us with the "That's what she said" ahhaha

I love how simple it is

THE GOON PONTOON

Still think you guys need to check out Skeeter Vac for misquote control. They run off propane and can cover multiple acres. Mine covers our 3 acre farm and my mom has one on a lake in woods that covers 1.5acres. Varies based on model and you can start them in May and throughout the summer have no bugs😁

I loved this video you guys are such a good team on RU-vid! Hope your kayak works brother!!

You guys are nuts!!!! In like a really hilarious way though! Love it!😂😂😂😂😂😂

Bow fishing out of Diy kayak

Has a Truck still sticks pvc out the back window

Density of water 62.4lbs per cubic ft. Need roughly 3.2 cuft of displacement to float 200 lbs including the pvc. That equals to 14.5 ft roughly of tube, since you dont want the whole thing submerged double that so you need roughly 30 ft of 4.5" od tubing to make this work reasonably well. Keep up the great work!

Always twist your PVC when glueing it. Helps kinda eat the plastic and put better seal. Done electrical all my life and just kinda helps.

Lunkers to 2,000,000

Hunting, fishing, and lovin everyday That’s the prayer a country boy prays🤠

You could calculate the buoyancy, but in this case an easy approximation if you ignore that density of the pipe plastic is to just fill up the pipes with water and then weight the water. The foam was great just in case it leaks, but it does decrease the buoyancy. A simple mod to make this thing float would be to add some 5 gallon water bottles as pontoons. 5 gallons is a bit more than 40 pounds of floatation. If you put a bottle on each corner then it would probably balance pretty well too and you would look so stylish 🤠

Dashlane is GREAT. Have used it for about 3 yrs, syncs between all your devices. TWO thumbs up!!

Foam in boats is more emergency floatation in the case that the boat fills up or capsizes. Inflatable bladders would be a better idea in case of leakage of the pipes. To increase buoyancy you need to increase the volume without increasing the weight.

The Loctite brand of that expanding foam is much much better. Trust me.

That was so close to floating Rob! Maybe more tubes need added or some floats down the center that are lightweight?

I ain’t got a kayak 😂😂 nah jk man great videos love your channel been watching for about a year or two. Keep up the good work!

“High speed low drag”... the phrase of my people. Congrats on the 1 mil!

That's so cool. Do another!

Each of those pipe displace approximately 54lbs. If you estimate the weight of the kayak at 200lbs and roughly another 200lbs for you and any gear, you would need about eight of those pipe to hold you above the water line.

Wow , I laughed a lot 😂🤣 . That’s submarine ? 🤣😂😅

Why not put pool noodles in the pipes?

I'd fish out of it...

I think you need to make sure the foam is all the way through the Pipe and dry, also pipe front and back

I built a very similar boat one year ago. Mine actually worked, but was heavy. it was loads of fun...

The foam increases the density. You added mass to the same volume, mass/volume=density. More dense equals less buoyant. In the short term it makes it a safer boat because a leak wouldn't fill the pipe as quickly, but the foam will break down fairly quickly, so ultimately all it did was cost more.

Wait Rob was accused of being the guy that crashed the Malaysian airlines flight?! Holy shit thats an insane story lol

16:08 is the funniest lunkers moment ever lmfaooooo

🤣🤣🤣🤣The good thing is he dont threw it in the deep side lmao

gnarlyyyy

Lol, foam doesn't equal more buoyancy XD

Who owns the phone owns the lurkers identity. *GASP* :O 😱😱

Rob thank you so much for your service you protect our country and I appreciate that thank you again

LOL! Awesome video!

#ssturdbucket.. that's the name for it..

I recommend you, instead putting 2"x4" (wood)across, continue using pvc, you gonna need 10 ,"T"s and lot of cuts but that would make it more lighter and resistant to the pressure

“Your outfit is very dad-like”. line of the day

Meet up wisconsin plzzz

Steven no strong:(

Hey, you might want to check your cement because that glue is for CPVC.

Where did you get the boat seats and where do you buy Flex Seal? Thanks!

For sure gonna try! Keep up the amazing job!

What happened to military Monday's

The best part is when you talk about cement cooling, then you skip to sitting in the tail end. So awesome. U inspire me keep that up. Laughing so hard right now. U are the shizzzzz

Lunker, I too tried filling a closed container with some of that stuff which was supposed to expand to fill the interior of the container but failed terribly. The reason it doesn’t expand is that stuff needs air to activate the expansion process. To be honest, don’t put that stuff in the PVC pipes. If that stuff doesn’t float in air, then it’s heavier than air. Just cap both ends of the pipes, strap the pipes to the frame, and launch the “Pipe Dream”, (wait for it) downstream!

Foam is why it’s sinking

You can go to Walmart and buy a kayake for $150

Name it the Big Floating Turd!! Lol

LFG's catch was so smooth haha

Robs pale feet tho

Has anyone noticed that rob has been saying thicc as cardi B in like every video smh 🤦‍♂️

The pipes are more buoyant empty than with foam in them. It is a matter of displacing water , and the foam just makes the pipe heavier, thus less buoyant. If the pipe got a crack then the foam would help keep the water displaced keeping it afloat. The reason some boats (kayaks and canoes) have foam in the bow and stern is in the case of the boat capsizing it would stay somewhat afloat and not sink to the bottom of the lake.

Love your vids, this one was awesome!

You made a mini pontoon boat 😂 Put air valves and fill with helium =maxim buoyancy and if it leaks just refill

Im a plumber and the way you primered and glued the pvc pipe made me cringe

6:30 that was such a Peric moment

BETTER GET A COUPLE MORE PVC TO HOLD YOU UP IN WATER LOL.

I looked at this for 5 sec and knew that it wont displace enough water to support your weight....i dont know how you people survive

You should have put four pool noodles in each pipes it would definitely make it more buoyant

Congrats on 1 mil!

Congrats on 1mill Rob!!!

Good idea I'm making one but haven't got the extra money right now been working on making for year now now I do have a pontoon boat just like what your building were your feet in the water or I have a way to get my feet out of the water. But mines 6 ft long but the plug Is so big you stick your fist in it. Yeah. So last year I leaned back was July 29th my birthday camping trip birthdays the 30th. But I flipped the boat back lost my new rod and reel took 10 years to get a new rod and reel I won't buy new cause I always give my rid and reels away so I buy cheaper so I'm able to buy and give more. But my plug popped open it's on top. But I leaned back the pressure of the tub going under water some popped that top. My daughter yelled your sinking I tried to lean forward but with my back can't do that fast it filled I went backwards. I hear splash my daughter dove into the water and was at me before I could come up from going backwards. So got up hranned the boat and few rods and reels of course few were in a holder so they didn't go no we're but my new one done. My daughter was able to help get the boat flipped and to the shore. You no your daughter loves you when you flip a boat and she's to you before your back up I got a great girl. Best 17 years of my life raising her by my self all 17 years only had help 7 months. But hey this ain't about my boat it's yours. I hope you read this far or atleast watch a video here's a man who made one also but with 6in and 4in need 4 pipes unless you get lucky and find 8in pipes. But good job can't weight to see it finished but thanks for good content and nice finds there bet he likes that copper pipe hope he uses for something cool. Have a good week God bless ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0cMgQQRYh6c.html

Congrats on one million subscribers!

Love metal detecting!!! So much fun.. love the buckle! Also that buckle is possibly a colonial shoe buckle.. just didn't get a good look at it!

before I even see the video...i'd bet those pipes wont be buoyant enough... love the design and idea.... now i'll watch the video !

I am definitely trying this...

I love that they put the yak in the all complicated when there is a legitimate kayak launch ramp... right next to them.

... Barely 2 mins in, and I'm getting flash backs from Matt and Rob's last cardboard boat building challenge. RIP, surfboard...

What do you recommend for fishing off of docks?
