Next time when bending or molding HMW plastics, use HEAT! You can basically mold the entire sheet to fit the hull bottom. Boiling water is great for bending and molding it because of heat distribution, but also a rosebud torch, applied sparingly, and other heating methods can be used. Also, consider cyanocrylate/powder welding for joining pieces together. You will come up with a more robust design altogether.

[@TheSmokingMustache]

Probably the only time I've ever sat here thinking 'Man... Ethan should PROBABLY have a helmet for that creek..." And I'm not a safety anxious person in the slightest lol

[@HenloduToit]

Had the EXACT same thoughts - an accident can happen so quickly... And I'm also not a safety person at all...😀

[@matthewchin6454]

I'd wear a helmet before the life vest. Takes about 2" of water to drown when you're knocked out face down in a creek

[@demoths]

Yep, never really considered a helmet as a necessity for going up a creek, but that was a rough section, I would definitely want a brain bucket going up that

[@davidlewis3291]

Thank God it was all good. This time.

[@campervanbug7658]

Forehead stitches and broken noses🎉

[@Hootman865]

Not sure if Josh is just hangin for a few. But man, that’s one piece of the puzzle I had no idea you needed. Formidable team

[@isaacclark6749]

I'm also curious why he's been in the background the last couple videos

[@DanteYewToob]

@@isaacclark6749I know.. I was joking that he’s just a magic casual cowboy who shows up to help and offer lessons and then disappears! Hahahaha

[@lesgobrandon9826]

So, that was the guy with the twin turbo Toyota ute? Vague industries? I thought it was him!

[@scottspropertyservices6877]

Probably setting something up in the new workshop like a cnc or big plasma table. These boys shoot multiple project videos on the same day while they each work on something different so he could’v literally only been there for one day but has appeared on a couple different videos

[@benedictcumberbatch4275]

He looks like a midget driving around in that thing

[@RyanWithAviators]

Can you imagine how effective this sort of boat would be for Search and Rescue operations? Specifically for the searching part. It would be so easy to put it in the bed of a pickup or on a tiny off-road trailer and get it to remove streams with ease.

[@benw2751]

They have inflatable ones that would probably be better for that but yeah

[@badman187ification]

I could swear I just saw that boat being pulled on a trailer, lol. 441 Belleview. 👍👍👍✌️

[@bisket2003]

Honestly didn't expect another jet boat video, but I'm here for it!! YEEEWWWWWWW!!!! Happy Friday boys!

[@Eyespyd]

Thank you guys for the mini jet content. Its the reason I found and follow your channel. More please

[@andersonruppa-ot8bx]

For marking black uhmw, silver sharpies, or white paint pens are your best bet. Also for filling seams and gouges, you can take a small scrap, like a 1/4" wide strip, light the end on fire, and drip it like a candle. Definitely not good to breath in, but that at home plastic base welding.

[@htmmotoring]

White Paint pens are my new shop drug.. they are amazing

[@goosenotmaverick1156]

I personally do pink lol that way nobody steals em at work 😂

[@jlucasound]

@@goosenotmaverick1156 Genius!! 🤣

[@BreakOutOfTheAlgorithm]

Y'all never cease to amaze me on the builds that you do. Not to mention the silly shenanigans. 😂👍

[@jimmyBurnett]

I love it!!! Great idea in that boat. Looks like it's really fun and it's fun making it. Can't be more fun.

[@kleinbiker1]

An old fiberglass boat trick. Use the counter sink bit in reverse on the drill so you don’t accidentally counter sink too much.

[@ReignitedAuto]

I hope I never have to use this tip, but good tip! 😄

[@Benzy670]

I love how you put an ATV muffler in the boat and it became an ATB. All terrain boating is crazy lol

[@ranger6779]

As a 3rd shifter thank you guys for making videos longer. Love watching you guys regardless 45 mins of premium content

[@robertdarnell5141]

That would be a great sport, almost like rally racing, timed run up a streak of shallow river or creek, jumping over sandbars, hopping out as fast as you can to push your boat off of obstacles. Great event to attend, good spectator sport as well, not too expensive as well so low cost of entry.

[@FordHogge]

Always a good day when the mini jet boat gets time on the water. 💯

[@dereelmatts]

Sick as always! Let's see a full nighttime run!

[@Hootman865]

I hope you countersink

[@jlucasound]

Lights! Camera! Action!!...

[@randomdan85]

your channel has grown so fast. this is amazing because it allows yall to keep on building such amazing machines. Thank you for all the great content. Stay blessed.

[@TheMCFisk]

Always love the build montages ❤

[@TS34675]

Love the jet boat videos, always looks like a ton of fun.

[@memorris2]

Not one use of the word premium!!! That makes me so happy!!!

[@LivinRentFreeInUrHead]

They do use it a bit to excessively.

[@calebpovey4967]

10:14 10:43 you lied but ya 10 time every video it kills me

[@LivinRentFreeInUrHead]

@@calebpovey4967 I did hear it 4times One dude said it relatively quietly, another at the creek rocks. Another after the drone incident. Then the last right before the very end.

[@sebastiantaylor5213]

Out of the whole video said it twice in one minute

[@memorris2]

Yeah, they got a few in at the end......but so much better than just watching Will be a dumbass and saying it every 10 seconds hahahaha

[@dakotatristan692]

You all are living the dream!! Love watching the projects and I hope it never ends😁

[@asssm89]

You guys are an inspiration. The first 30 minutes was great, it showed how you can upgrade your boat without 30k+ of machine tools.

[@DataRew]

Now you guys need to make another similar boat, as it waaaaay more than doubles the fun! ❤❤❤

[@Billyjoe978]

Yes, everything’s always funner with a buddy 🤘🏼

[@joedoerksen9166]

It’s so good to see someone with impeccable skills in mechanical engineering and over all excellent fabrication skills

[@pullitupjamie810]

Lolllll

[@wirebrush]

The video I've been waiting for since this build started. That looks like so much fun!!

[@kilgorefamily76]

Nice! Fun day on the water with gorgeous scenery all around. That first part with you hiking through the brush along the river in your vest, had a solid Burt Reynold 'Deliverance' theme to it. Was waiting for the banjo music to start up. Good content as always.

[@thomasreimer1767]

As much as I enjoy watching you guys build something I even more enjoy seeing you have fun playing with your awesome toys and yes, it also makes me a bit jealous. 👍

[@raycar1165]

Nice to see Sam is doing well. That looks like a blast! Much ❤ Love 🌎🌍🌏⚡️☯️

[@stuartblack9258]

GRIND HARD .... building the best things you never knew you needed!! Just awesome guys! Cant wait to see the new shop up & running!👍 much love from the U.K 🇬🇧👍❤

[@fixit4182]

You guys are very enjoyable to watch. Very respectful bunch of fellas which means you have good percents. Stay safe

[@MultiDemension]

I can see a need for a little foldable oar mounted on the engine cover :)

[@JS_CIC]

That plastic welds very well. You can take a thin scrap and use it like a welding fill rod with light torch work.

[@jamesmcgee9279]

Awesome guys! Your channel is never short of any entertainment! Dead battery! Quick to the Jackery! Thanks for sharing.

[@jacko4483]

You may have been able to warm the plastic with a rosebud torch and get it to drape over the hull better. Just a thought.

[@lcrazyjeff]

I could only imagine how much it hurt to hit those rocks in that tiny boat

[@Hellsong89]

And damage it causes to boat that cost tons to build in parts not to mention labor that went to it. That armor is there to protect against rocks, not enable it to run on rock like its normal. Also leaving to expedition like that with out checking and double checking things like battery. Its same thing with bikes. You go to do physical work for whole day until you are exhausted, then tip your bike on its side and if you cant lift it up and kick to start, then its too heavy for you, that is just one of the things to consider when preparing to leave for expedition like that, cause you are utterly fucked if you run into issues middle of nowhere.

[@r00kiet80]

​@@Hellsong89who asked?

[@manicr1]

I just learned of you guys last night while watching an interview with Derek Bierri from VGG and I have to tell you I am SO glad I did! The projects you guys take on are really impressive and while I'm working my way through your channel I have to say, this jet boat project is TOP NOTCH. The fabricator (Ethan?) is the real deal and I love how creative he is at figuring out problems. I also love that y'all show your errors as well. Keep up the fantastic work as your skill sets will only improve! Thank you for the entertainment!

[@kevinAuman1]

I love that Josh made it out to the property! Sure hope you showed him the treehouse and everything!

[@AntonioClaudioMichael]

You guys are always doing something insane and I love it 😂😂 1:36

[@hcwaffles8912]

imagine being a fisherman and going all the way up a secluded creek to escape the boats disturbing the fish and this mf just flies by 🤣

[@AntonioClaudioMichael]

Drone footage is just dope guys

[@harrygreen6935]

So sick! What a ride it is. Outstanding!

[@nabilali3230]

Tip for you guys. You can use the counter sink tool on plastic with a power drill but the trick is to put it in reverse and let it melt slowly while it heats up

[@jmoney29871]

Is there a reason you couldn't heat and bend the plastic to "mold" it to the bottom of the boat rather than cut and bend? I think the size of the piece would make it tricky but not impossible. Either way, looks great!

[@thorstenwolters9025]

I had the same thought!

[@broodaiamdewey622]

The plastic is probably too thick to properly heat or won't maintain the same properties and might deform.

[@matthewchin6454]

you could potentially use the boat as a vacuum forming buck and use a sheet of kydex but that would take a lot of prep, a big machine to get it heated properly, and lots of trimming

[@DanteYewToob]

@@broodaiamdewey622That was my thought… maybe when that plastic is heated and cools it becomes brittle and defeats the whole purpose of using it as a protective layer…

[@PhonePhreak3z]

Gosh that thing looks like so much fun!!

[@ben7274]

It was great to see Sam back! Great video as always.

[@hydealmen5280]

Powder coat paint the jet boats than a rap doesn’t come off anymore

[@ecurb2]

Granky guy here. If you are not going to wear a helmet, why wear the life vest. Love your chanel. Just want you nummies to stat safe.

[@bobbleheadlova]

Life has been kicking mine lately. Smiled a mile wide when I saw that you had a new upload. Thanks :)

[@mattgraham1983]

Its always an awesome video when Josh randomly pops up 👍👍

[@reviewaccount469]

When you were going up stream over those rocks, I had a grin on my face the whole time. Completely badass! Too bad it ended short but it was probably getting too shallow anyway.

[@donzagamingofficial8902]

I love all the mini builds, theyre the whole reason i subscribed ❤

[@Unapologetic400]

Probably the 1st 360 I've seen, with a BOAT! WELL DONE ETHAN💪

[@jenkinsj0672]

There needs to be a Cleetus collab with this crew!

[@larsstougaard7097]

These guys mad respect

[@user-gx4qw5lv5p]

you need to build another small boat (a 2 seater would be nice) for filming and rescue missions like these

[@DetroitMicroSound]

The new addition to the crew is great!

[@wiresmith2398]

WHOO! That new muffler makes that thing sound PREMIUM.

[@Grimm-Gaming]

Cant wait for yall to somehow convince Cleetus to try n fit in that thing! Haha

[@ChargerrentalCoandammo]

Will is my spirit animal.

[@newt2010]

Awesome job at the add-on. Also, what a great grate. Cheers

[@PascalVos]

make 2 more please of these nice boats, love to see a pack of them running on the lake :D

[@russellzauner]

Next time use your drone pilot to help you chart the river - with the right contrast and polarizing filter you'll be able to see everything, just cruise 10 feet above the water (make sure to scout your fishing holes this way too, you should be able to see any fish/lost beers).

[@MrPunkkis]

That boat is sick! :D

[@AjGalloway95]

Edwin always expanding the jukebox! I love the Turkish sounding stuff and the 70’s funky vibes

I am a 15 year old Alaskan kid and watch all your videos and love what you do. I drive 20ft jet boats and drive atvs and 160hp snowmobiles but this little jet boat would be amazing fun and I could take it to so many amazing places in Alaska. It would be so much fun.
