Tapering the material to be thinner at the edges can allow higher speeds. For instance, the wheels of a supersonic car have a lens-shaped cross-section. As a bonus that should allow for jetting more towards the center of the wheel thereby providing leverage that allows the wheel's edge to spin faster than the speed of the water.
First reply in 18 minutes?!
yes, moment of inertia. maybe have two cylinders of different diameters, so they can shoot the water at the small, thick one, while a thin, large diameter part is spinning with more angular velocity
WAIT, ARE YOU CODY??
Interesting… we’ll have to try that on our next spinning wheel endeavor
Hi Cody
More Cody videos please. Chickenhole base vid?
The problem with the bullet proof glass wheel was you had the waterjet hitting in between the layers of the bullet proof glass so it was just separating/destroying the weakest layers causing it to blow apart faster than probably if it was designed the other way (instead of looking at the face of the bullet proof glass having a hole in it, it should have been the side of the bullet proof glass having a hole in it).
bulletproof glass is designed to be strong from the front, not from the side
could probably get around that by encasing the glass in resin as well as having resin between the layers. Even so, it likely would slightly perform better than what was done in this video since it's similar to the broken glass in resin wheel.
It would delaminate and be destroyed faster, thats my guess
Or if it had been spun normally from the center rather than using outside force and friction causing erosion to begin with
Bullet proof glass isn’t resistant to centrifugal force, only kinetic energy from the front/back.
Mad respect for picking up a black widow spider. I've seen maybe 2 or 3 in my whole life and it took a lot to rebuild my house each time after I burned it down.
Literally saw a half dozen this summer in Arizona.
They aren't mean or really bad spiders they are fairly docile and most of the time hide and run!
@@CalebCantrellPBR True, and if you look into the actual danger of their bites... they're not often fatal, though I'm not volunteering to get bit any time soon.
😂😂 координально
Bro, after a single incident like these, the hydraulic press channel decided to build a concrete bunker around the test area. And you, things keep exploding and flying in every direction and you just chuckle and move on. You are certainly playing with the odds.
He's like .1% of the area something flying could hit, so the odds are in his favor... until they suddenly, violently, aren't.
He shouldn't even need a chamber, surely all the electronics can be moved further back or operated remotely. It doesn't look like anything needs to be constantly held down in order to operate like a Sawstop, but it's possible there's some regulations since it's a shop, they have to follow OSHA rules or the owner will lose their license or something. If not, it's just foolish.
Definitely playing with the odds...anyone who has worked with dangerous machinery knows it's a matter of time, especially if you play fast and loose like they do.
I wish them the best obviously but can't help but feel uncomfortable when I watch these videos
"Or we will waterjet your house in half" Got me!
"Daniel will you waterjet me" 🤣
🤔
Welp my mind is in the gutter
Daniel do you want to be twins 🤗
@snowballil3133 😅 well it was a gay reference so!!
What I like about this channel is that every video feels like the first video all over again
they need to bring back mail time.
Thank you for telling me I'm special for pausing the video. ❤
Your his special little boy
at 0:10 you look like a "hello fellow kids" dollar store version of Steve Buscemi
Seriously hoping the "30-year-old toddler" look doesn't catch on
Glad someone noticed
Dude, you're actually so funny, i have TEARS.
Just stopping by to appreciate how nice your waterjet is and how well maintained it is :)
I love your videos. You can probably tell because I watch every single one. But I still wanted to tell you! This was a particularly fun one to watch!
I love you Tracy!
Getting flash banged by cardboard Nate was not expected
Thanks for video and hello from Russia
I am surprised this channel is still going strong, at least three different changes in the face of the channel, but the heart stays the same as day one.
Aw the marriage proposal bit was actually so cute!! Hahahah that was awesome
Your personality is unmatched. Great videos!
9:41 Mickey Mouse? Is that you? Are you finally back from prison?
There's a company in Woodlands Texas called ChampionX. They make Diamondback 3D printer nozzles out of a substance called "Bort", or polycrystaline diamond. Unlike regular diamonds which are incredibly hard, but brittle and easily smashed, borts are incredibly hard and very durable (those nozzles are basically invincible). You should reach out to them and see how big of a bort they're able to make, and if they could make a bort skateboard wheel. I can pretty much guarantee the algorithm would love a title like, "Spinning a solid diamond skateboard wheel at hypersonic speeds", and a thumbnail with "REAL DIAMOND" in it...
Everytime they post a video we can confirm that Daniel didn't die this week. Hope we'll seeing another video next week.
Daniel’s outfit? Damn😅😍
love this guy.
I like seeing the resin wheels filled with different materials.
I've been watching this glass artist's youtube channel and apparently there is a resin specifically for glass. You should look into getting some and see if it makes the bulletproof glass better
4:15 The tool you're looking for is an arbor press. You can use a piece of material just smaller than your bearing OD and just bigger than the ring's ID, and pass it through the other side, then press the ring out.
I absolutely LOVE your videos.
Oh god he’s back in the shop
Thank you for calling me special ☺️
10:55 - giggles!
we're special
I don't stop this video.
I watch in slow motion.
Like a boss 😎
I love Skip to Highlight feature
Clicked on this video bc I haven't watched this channel in years, what happend to the two OG guys that used to be on here
They sold the channel to the guy that makes the rings
@@Zet-qk9drPatrick Adair? The guy that makes the stupidly overpriced rings that idiots with too much money buy?

Im happy to see you didn't kill that spider. I have a few pet black widows that ive caught at my job.
Omg i love your videos man!!!
Roda gira, roda quebra, homem feliz 😊
Special and proud!
Your videos are awesome 🤣🤣🤣👍
Not always a fan of the new presentation style however I really enjoyed this video. Thanks a lot.
The pressure of the sand and glass might have deformed the silicone. Had some issues with that before, if you try these again try some heavy duty molding silicone. i use dragon skin silicone for my molds.
Also, use a soft silicone coating on the original part and then cast that in a hard material (often plaster-soaked bandages).
Ok, WaterJet Punks, you got me to stop on this one!
Thanks, I am special. Sometimes its nice to be reminded of such. Cheers.
"composite materials are made from a fiber and an epoxy matrix. the matrix is good for compression, whereas the fibers will take the tension"
waterjet channel : "let's make a glass shard- reinforced epoxy wheel, and then subject it exclusively to tension"
Broken glass is glass but broken. Wise words
The mold was made circular, but had no support to keep it that way. The material being cast pushed out on the mold asymmetrically. Make the mold in a box and keep the box for later when you do the casting. This will help it keep its shape.
love the video
You should get a rear sprocket from a bicycle and hit each gear 1 at a time. You'd probably get world record land speed with the gear reduction to the imaginary wheels. free banger of a video right there.
When trying to make bulletproof glass again, may I suggest setting up all your layers, get the air bubbles out of the resin, and then using a spong brush to brush the resin on each layer as you stack it, you will have to leave it where you make it but it will be a big block of BP glass you can cut stuff out of it maybe
This channel should be renamed "the incoming shrapnel channel"
Blippi's c list brother? Jk love you guy with glasses
You should coat some of your next creations in Line-X, that spray coating that makes stuff indestructible. See how that will fair
The problem with spinning these up with the waterjet is that the waterjet, whether using the abrasive or not, is going to start eating into the material as it's spinning and weaken the structure until it has enough of a defect that causes it to come apart. If you really wanted to know how fast you can spin them to see when they come apart from their own rotational velocity, you'd have to spin them through some non-destructive method so that any defects that arise, come from rotating the material alone. That and if you want a perfect wheel, you need to make a solid puck or block of whatever material and machine it down in a cnc machine to be perfectly balanced and fit the bearings perfectly. I get that you want to use the waterjet because that's the channel name and it's how you've done things for a long time, but you could at least machine the wheels to be effectively perfect.
El video es muy bueno 😁
9:09 late 80s, early 90s F1 cars
Yay
"or we will waterjet your house in half"
Good thing i dont have a house
Sal vulcano ahh
you might want to do something about how you attach the wheel. The bolt is turning. see 6:39 for example. Also inhaling glass dust is no joke.
As he demonstrated at the beginning and on ther videos, he likes to live life on the edge
Interestingly glass dust isn't nearly as bad as quartz dust. crystalline materials hold an edge on the atomic scale much better than amorphous materials.
Is there a way to rig up a shaft thats strong enough to be spun by the water jet, maybe with like steel or titanium fins on it, so that the wheel of random material can just spin and not be affected by the jet itself?
Just use a pressured water pipe as the axle, and have have two off center holes on opposite sides. Optionally, extend those away from the center of rotation with curved pipes to get even faster speeds. The water comes out at the opposite angle of rotation at all times at high speed. It will keep ramping up until the considerable force of the extremely high pressure water is equal to the force of air resistance on the extenders, plus minimal air resistance from the axle rotating, plus the friction of bearings.
Right so a water jet is better then a gun when facing bulletproof glass… criminals get your note books out and a pen 😂
I don't know if you have tried this yet, but I imagine the rotation of the objects causes tensile stress in the material until the stress gets so high it rips itself apart. So, why not try a tungsten wheel, as tungsten has the highest tensile strength of any natural metal. I tried looking up alloys with greater tensile strength, but all I could find was people saying they exist but not saying what they are? The highest tensile strength material is graphene which obviously you will not be able to make a wheel out of, but it's tensile strength is about 130 times greater than tungsten even. I would dare to guess the tungsten wheel would not explode, unless you modified it so that it's just a tungsten ring around a filler material, in which case you could make the ring thinner and thinner till the tensile stress is greater than the tensile strength. In fact, that could be a cool project all together, gradually increasing the thickness of the tungsten until you find out the tipping point between exploding and retaining it's shape. Or maybe the solid tungsten wheel would just explode idk.
You're more of an expert with materials than I am, so I'd love your input. If I were to use resin to mold clear beyblade parts, do you think the resin you used in this video would be impact resistant enough to survive beyblade battles?
Not if you spin the Beyblades at 6k RPM.
Don't use plain resin. Make it *composite* by using, say, fiberglass. You can buy shreds (as opposed to sheets) that are meant for molding like that.
Close enough to stopping a bullet with the waterjet that i am satisfied for now
8:34 NFTI is also present...nice!!
Your great-grandchildren will be finding glass shards in there!
With all the years you guys have been doing this, I would have thought that you would have a rig to balance all these things... If you really want to reach max speed without things blowing up balancing would be the most important thing I would think!
how about mixing resin with graphene or carbon fiber. DO you balance them?
Honestly it makes sense, if the plexiglass wasn't really contributing at all then the glass+resin wheel and the glass+plexi+resin wheel should perform about the same
7:27 its crazy when you pause it right as it splits into 4's it turns see through cuz of how fast its going on the frames I'm guessing?
“Break a speed record” *Proceeds to spin wheels at thousands of rpm*
You should make a wheel using ground up flint and resin, maybe sparks?
@ 4:17 It's called a _Race Remover_ 😆
Looks just like the CSUF machine shop
You guys should try making an air bearing for these demos !
Could you test big bearings, just the bearings on their own, and different types like roller bearings and ball bearings, to see how fast they go before they fail.
Could you use the waterjet to make a wheel more wheel-shaped while it is spinning?
I think it is important they are very wheel-shaped.
Your costumes crack me up
I love this channel. I just wish youd give us some info about the waterjet.
Its very suspicious that youve never mentioned the pressure.. how many PSI does the waterjet produce???
He mentioned it 0:55 exactly
@8:26 NATE FROM THE INTERNET xD
Want a true test to see how fast something can spin without the extra variable of the waterjet touching and damaging the item? Build a finned wheel onto the shaft that the water jet hits and spins and let the item of test to sit attached to that shaft. The finned wheel should be a strong enough material to resist coming apart.
8:26 - The problem w/ the mold was that it didn't have reinforcement on the sides and when you put the side on it bulged the mold causing the bearing locations to be different, causing the wonky wheel... You could have wrapped it in duck tape or gorilla tape before pouring the stuff in or put it in a container to keep it true. Maybe next time.... 😁👍😂
STEEL BALL RUN🎶STEEL BALL RUUUUUUNNNNN🎶
6:13 - what's with Nate in the background? how did he get there?
A very interesting video! Since childhood, I have also been interested in things that can be called extreme. For example, will a match light up and how will it burn at a pressure of 10 or 100 atmospheres? How will the electric motor behave with a smooth increase in frequency from the standard 50 Hertz to 100, 200....400 hertz? What will happen to a bullet flying through a cutting jet of water?
The mold is fine. You just needed to make the mold a shell so that the soft silicone didn’t deform while curing.
Bulletproof glass wasn't that strong because the water jet hit the sides, and it can take a lot more compressive force than shear force. You could get it to work a lot better if you cut progressively smaller circles to make the wheel, but the wheel would only be as thick as the sheet of glass you cut it from. The sand didn't care because its one solid object.
Great video btw!
The end video link is to cutting wood not spinning things?
Over 10% likes! Keep it up people!
LET’S GET DANGEROUS!
thanks, i know im special! :)
Bro got that Vector fit.
Pure plexiglass wheel would be pretty cool
Thank you for adding a Russian translation. true, AI translates crookedly, but still the essence is clear
12:54 missed opportunity for a classic “Don’t breathe this” 😢
for those people who wants to know the speed of the spinning wheels in kmph or mph
The speed of the 3d printed wheel is about:
274 kmph or 170 mph
the speed of the sand wheel is about :
1357 kmph or 843 mph
the speed of the glass shard wheel is about:
788 kmph or 489 mph
And the speed of the bullet proof glass wheel is about:
777 kmph or 482 mph
Keep it in mind that these values are not completely accurate.
Like this videos thumbnail
Mach3 is 2301 mph
Mach2 is 1534 mph
And Mach1 is 767 mph
The Mach 3 in the thumbnail is for the water leaving the waterjet. But I’d be lying if I said I didn’t think some people would think it’s for the wheel lol
@@WaterjetChannel sorry I got confused.
nice
Good to know other people have PTSD of going to Joann's fabric
pink gatorlyte @ 6:20 is so real bro
the fact a small little thing like that can hit the big thick metal disc and send it flying like that? Yeah, that shrapnel'll put a hole'in'ya.
you gotta feature the cincinati press brake in a video

It amazes me you still haven't upgraded the shield to protect the waterjet.
