Notes: This is a dry vase and is not designed to hold liquid, despite being formed by water!
The graphite finish does not come off, so does not mark hands or surfaces. Here's where I found out about it th-cam.com/video/5smcTUJYoVE/w-d-xo.html
Connor Holland hi, will you be selling any of these?
Yes, they are made to order and will be added to my website shop soon www.connorholland.com/shop.html
do you make ones in silver? like candle holders
insert a sleeve so that it can hold water....
you could probably mark out any leaks it sprung during hydroforming process and weld them up later on
never thought i wanted to see a stack of hexagonal steel pillows...
Those aren't pillows . . .
yeah
but it looks puffy and pillow-y
Steel Pillow Club (SPC)
I remember seeing them do this on Mythbusters as a kid and it blew my mind at the time that a power washer could bend metal like that. Still awesome.
It seems like you could make it into a really cool centerpiece for a fountain
If I make it I’ll post it. In the process off opening a start up for one off water features.
one way to test your welds
Should be working for SpaceX
They squeeze (check welds preasure test boilers) with pressure washers... Before they clear out scaffold.
@@heuben Ive welded parts for space x... and no.
i don’t know if this is a joke or not, but hydro testing is actually a way to test welds on pressure vessels and piping
@@loganhugmeyer2756 no you haven't.
Interesting idea. I could also see that design looking nice as a water feature with low pressure water being pumped up through the middle and cascading down the sides in 6 waterfalls. The coanda effect would pull the water most of the way around each section before letting go of the surface and falling to the next section. I could imagine it being quite a pretty effect.
That's not Coanda, but Hydrogen Bond ;)
You nailed the execution of this, and the finish you chose for it is perfect. It's magnificent!
Thank you!
Absolutely beautiful. I love the finish, I never thought of using graphite powder to get that kind of onyx ebony steel style look! I absolutely have to try that.
Thank you! I'm looking forward to using the finish again on future projects
Plz guide me which pressure machine you are using
I mean about psi and bat
@@renugupta3032 I use a CoTech 90 bar pressure washer. It does not need much pressure to inflate.
Will it really not rub off? I'll have to look for videos about using graphite powder on finishing.
Not gonna lie, I was terrified when you started filling it!
Don't worry I'm a professional ;) The water pressure never gets dangerously high, as it escapes though pinholes like at 3:07
Why? There are several reasons why that is pointless. He's only dealing with less than 100 PSI, hydraulic systems on heavy equipment operates in the 10 to 15 thousand PSI range without incident. Second, water is non compressible, which means it doesn't store energy. If you fill a 1 gallon tank with air at 100 PSI you've probably put at least 10 actual gallons of air in the tank, compressed. So if the tank ruptures, 1 gallon very quickly becomes 10 gallons. If you fill a 1 gallon tank with water at 100 PSI, it does NOT compress and so is only actually 1 gallon. If the tank ruptures the water just falls on the floor. The only reason it looks like the water is compressed and sprays out of the leaking joint when he turns the pressure washer off is because the shape of the vase is springy and when the steel contracts a bit pressing the water out. It doesn't matter how big a hydraulic tank or water tank is, or how much pressure it is under, if it ruptures it immediately equalizes pressure and becomes safe. Now if the tank is also full of a ton of compressed air you will have a significant problem. In the process shown in this video the smart thing to do would be to use a hose to fill the pre expanded vase structure to the top with water before hooking it to the pressure washer. Even though that is not done the risk is still relatively low because the pre expanded structure has such a low volume of air in it that it wont expand much.
@@14768 small home pressure washers like he shows in the video tend to operate between 1000-3000psi. It looks like he is using this: www.thegardentoolshed.co.uk/product-offers/cotech-90-pressure-washer-at-clas-ohlson which can operate at 90 bar (although in Colin's video, th-cam.com/video/HpjAq1Nq4X4/w-d-xo.html, he mentions at one point only needing 20bar/290psi to do his forming; YMMV), so 90bar*14.5psi/bar ~= 1305psi. A Kärcher K7 series pressure washer gets up to more like 180bar ~ 2610psi. A more beefy home pressure washer running off higher voltage even goes a bit higher, over 3000psi. But I mostly agree that this hydroforming is reasonably safe. It's basically like hydrostatic testing (en.wikipedia.org/wiki/Hydrostatic_test) which does mention some issues "A pressurised hose that is not securely attached or which fails under pressure may whip around" and "leak of high pressure liquid can cut or penetrate the skin" ...so I wouldn't hold the object under test in my hand. Also, if the pressure washer is still running and the rupture is less than or equal to the size of the pressure washer hose, well, I guess it will keep shooting out water out of that hole like a pressure washer would, which is kinda strong. Here's an example of a steel form blowing up under hydroforming pressure that Colin Furze did, doesn't seem to be very dramatic...although you'd think he'd want to at least put some safety glasses on :) : th-cam.com/video/llhcATrmsBg/w-d-xo.html
@@perspectivex100% wrong. That's a theoretical max pressure output of the machine if it's dead headed. The steel sheet is yielding so the machine can't reach max pressure. You're pressure limited by the bending moment of steel and total surface area of the sheets. I guarantee you it's no more than a few hundred psi. If you rewind and watch when he hooks up the garden hose before he turns the machine on the steel already begins to move with just house water pressure which is only about 40 psi.
Again, still moot, even at 10k psi it's completely safe.
@@14768 "100%" is a very provocative exaggeration as it sounds like you're referring to everything I said. If you take issue with one point, like you mention, it would be nice to target just that. But you're right, when I wrote "operates" I felt like that wasn't quite right somehow, I mean, the pressure washer can, but doesn't have to be, that high pressure, so I updated my comment. Anyway, I've investigated some more and see Colin measured his pressure washer attempt on a metal piece that at least looks similar in thickness at around 20bar / 290psi; th-cam.com/video/HpjAq1Nq4X4/w-d-xo.html. Another diy hydroformer says his piece used 90bar / 1305psi but it's not clear if he measured that or assumed it based on the max his machine was supposed to put out: th-cam.com/video/RQE9cJApSgQ/w-d-xo.html, and it looks anyway like the sheet he's using could be thicker.
Why is this in my recommendation? I’d not know, but I enjoyed every second of it.
very cool, reminds me of something I would see in an expensive kitchen
Elegant demonstration of your skills, congratulations
Okay you got me with the graphite powder. I never thought of that or seen that before that's a great idea.
What is this powder used for? I dont get it.
The end coloring
@@ipodhty Okay. Interesting that it seems to stick.
Don't know why but it made me think of how cool it would be as a pawn in giant outdoor chess set!! I wonder if that's doable
love the sound of a TIG torch on pulse
This entire concept an the execution of it was all done so well! Very cool video!
Very cool! Thanks for sharing!
That is amazing. Thank You
The graphite finish is awesome! Will have to try that on my next random project!
It's awesome what you can do with a welding machine and a pressure washer!
That looks like the body of an AMAZING lamp.
I'm thinking about making one. I'm just deciding whether to use a shade, or an exposed decorative bulb
geez what a game changer for forming parts.
I would never have thought you could use a preassure washer from Clas Ohlson for hydroforming.
You could also use a cylindrical glass vase and glue it inside of the structure to make it a normal water vase.
A glass test tube would work well. The hole on top can be sized to fit the diameter, so the tube rests on its lip.
Excellent. A one off for sure.
Slick finish!
I remember seeing Colin furze do this same method to form pulse jet motors.
I'd like a hot water bottle.
Dude that's awesome and original
Lovely to watch the process. And great video editing
Thanks for watching Ben, glad you like it!
That was cool to watch
Talent has no boundaries
Wonderfully Fantastic 👍😎
I think this could work as a musical instrument
woah thats insane dude
That look so clean
looove...so fun...
Very cool
When it blows up that means you're done. LOL
This is genius !
Excelente muy bueno
Great video, I liked the camera angles for the tig welding shots. Subbed for more!
Thank you!
Could I suggest a 2stroke expansion exhaust, I have seen 1 done this way , although not as exact as your fabrication.... would be interesting to a lot of enthusiasts...cheers ,nice job.
really cool to make unique stuff like this. only one in the world!
edit: Unless you made another one of course?
I plan to make some different variations, with different shapes and sizes
Thank you for using a filter on the camera.
Great stuff. Keep going.
quite concistent welding, judging from the consistent final form. what bar did you use? sheet thickness?
Cool , gotcha . 👍
Lovely
This is my kind of art.
Hey that's pretty awesome, different creations, thanks for sharing, Gene Cooksey woodworking
Thank you Gene
Man, I would love to weld with this machine, very clean
This is insane! In a good way!
Came across something similar on one of those Raw Craft with Anthony Bourdain videos using compressed air instead of water. Really cool and artistic process. Thanks for sharing.
Thank you, found it: th-cam.com/video/TTlG1BPoj-I/w-d-xo.html
@@ConnorHolland yup that's the one. Pretty badass process. I think your method is safer without the molten steel and sparks.
Yep, I use 1mm thick steel sheet which can be shaped quite easily without heat
Damn, using compressed gas is very dangerous. In the oil and gas industry we always try to use liquids to pressure test equipment. If they fail the energy released is orders of magnitude less than a compressed gas.
Watching you do this was cool. Except for the constant fear of explosion 😂
This would also make a very cool lamp!

Awesome vid, could you show closeups of the welds?
Very nice.
Very very cool, I'm exploring the same technique, staying away from inflating with air/gas as its dangerous. Don't know aything about the graphite powder finish technique but it looks very nice ! Curious about how you go about with that any links for more info on that ?
Thanks, here's a quick walkthrough of the graphite process: th-cam.com/video/BSuEIMpj_S4/w-d-xo.html
Hydroforming is safer if you're new to the process, or need high pressure to fully inflate a piece. I use compressed air (Aeroforming) for pieces that require very low inflation pressure, as it's less messy and more precise: www.connorholland.com/aeroformed-chair.html
what made you thought of this shape and what is the application for it?
Beautiful art. Subscribed. How much metal is used
Why do I feel like this needs to be on the end of a war-staff
This is really awesome, I'd like to try it myself!
It looked like your tig rod was a little over sized, you might want to try a smaller diameter.
Thank you. Yes I think I should get some 1mm rods, I currently have 1.6mm
Holy shit
That was cool!
Yknow this could be a interesting concept to build homes with. Just take 2 large sheets and blow them up with water, cut holes for doors and windows, reinforce a bit, and spray some protection and voila a tiny house.
or boats
There is a concept of doing concrete sheds by wetting a cement impregnated fabric shell and then inflating it with a leafblower. Super simple and gets ridgid after drying.
that thing would be amazing with a mirror chrome plating
Very good
impressive welds
cool
Good video
Great work!! I think your work is so much cooler than Jeff Koons' ;)
So dumb question but do you have to worry about rust from the inside? Like water on the bare metal inside when it dries out then I imagine you have some nooks in there that still have some moisture and start to rust.
No, I heated it up to remove any moisture, and there's still no rust after over a year
So, how much for the "scrap" bottom piece you cut off, finished like this vase was? I need a cool bowl as a conversation piece!
Here's my contact page (www.connorholland.com/about.html). Please send me an email so we can work out the details, thank you!
Nice
I see you are familiar with l cornelissons too then! Great shop!
What made you go with the hexagonal plates instead of the circular ones?
Was it your floor?
When you inflate metal the outer edges are pulled towards the center, so circular shapes often develop large wrinkles/dents. I also really like hexagons!
well, it would be some work, but you could hydroform the disks one at a time in a proper clamping setup!
30 grade angle on the tungsten rod bro. More pointer, more focus, ends up with nicer weldings. Best regards Sweden
please someone anwser me if this tecnique could be usable in space constructions? like build in deep space/orbit with a bot robot wharever that could be programmed for.
Yes it is certainly possible using compressed gas. The welding needs to be perfect and rated for the required pressure, but that is standard for the space industry. I also like the idea of inflated structures on the Moon and Mars.
does the graphite wears out with manipulation? or did you aplied some protective coating over it?
I buff the graphite with a cloth until it is fully embedded into the paint, and does not rub off. I think it will be as durable as the paint finish, I haven't yet tested it with anything abrasive. A clear coating would give added protection for pieces that are handled more often, and stop fingerprints marking the surface
@@ConnorHolland so it is black painted first... wondering what that was.... Looks great! You could have also used phosporic acid and some volts to remove the heat discoloration: see minute mark 4 in th-cam.com/video/DGl2EQgoKfg/w-d-xo.html
Love to see some hotwire cut lost-styrofoam aluminium casting art!
@@ConnorHolland
Hey bud, cool work.
I'm also a fabricator and painter.
Clear the paint, then add the graphite.
Give the clear a day to dry.
You will get the same result but your paint will be protected 100%.
✌N ❤
Lamp base?
No music.... thumbs up!
I wonder if you could use a much thicker base plate that wouldn't form, so you didn't have to cut it off after you're done? Either way it looks awesome.
That's a very good idea, thank you. A heavy base will also give an object more stability.
This guy loves hexagons
Sure do!
Badass
So that's how ashtrays we're made.
Can you tell me which pressure washer used for this work
Cotech 90 bar pressure washer, but any other machine should also work
@@ConnorHolland thanks and regards dear brother
What is the capacity and pressure of the water pump?
It is a 90 Bar pressure washer
bet he´s listening to "push it to the limit" when he´s pressurising these :D
I feel like this is something I’d see in the Iron Giant
What was the pulsing for in those welds? Seemed a bit too fast
I'm still quite new to TIG welding and experimenting with different settings, I'll try lowering the pulse frequency
@@ConnorHolland Don't bother with pulse yet, work on keeping your torch hand steady and your filler rod feeding consistant. Then work on heat balance/distortion control. Gotta learn to walk before you can run and increasing variables only steepens the learning curve.
this would work amazingly for lifting heavy things like with the metal vase you could have just put it under a car and it would lift it up
Should grind the seams perfectly smooth
Look at u and your sentinel hood lol lucky guy
Make a water water fountain with it
Looks like the quantum triangulation quintupler we need.
Oh boy, oh boy, that sure looks dangerous. I'd make sure to be behind something strong when messing with steel bending pressures and metal containers!
Thankfully since water (in practice) isn't compressible, as long as you're not touching or holding onto it, it's reasonably safe. If it sprung a leak and you were holding onto it where the leak occurred, you could get a hydraulic injection injury, but even just being a few feet away is fine. It's not like air, which can compress greatly and would cause an explosion. If the container ruptures, since the water didn't compress, just a little bit more space is all it needs to lose all pressure, and so it isn't going to throw metal everywhere.
That said, caution is a good idea, but it's not nearly so dangerous as to need a strong shield of any kind, especially not if you're at any distance from it.
@@Pyrichia you know how you look for a high pressure fluid leak? With a broomstick. Wave it around in front of you and where the broomstick suddenly gets shorter is where your leak is!
Is it painted and then rubbed with the graphite powder?
Yes, with gloss black spray paint
@@ConnorHolland thanks for the reply! Can you explain what's happening? Does the graphite rub the paint off?
@@thomasvmanning The graphite crystals embed into the layer of paint, which can then be buffed to increase shine
Didn't know that some Klingons still use Hydroforming.
What gauge steel are you working with?
1mm thick
Thank you
3:40 Self lubricating steel! What will the invent next!?
priceless
Clas Ohlson high pressure washer!
Muffle looking like that. What would be the sound like haha
