Hydroforming Cube with a Pressure Washer

How to use DIY Hydroforming to inflate steel cubes from flat to 3D. The first experiment attempts to mimic an expanding paper origami cube, but proved to be much trickier to achieve using sheet steel due to the large force required to unfold correctly. I may try this again, inspired by how the MythBusters managed to make an inflatable cube/balloon from sheets of lead.

It's more of a stress test for the welds.

4:46 - Most. Painful. Beach ball. Ever.

Wasn't planning on watching an awesome hydroforming video today, but here I am watching an awesome hydroforming video.

[@alanshelby5980]

Being from the old school of oxy acetylene welding You might try that instead of tig welding . 2 U-shape bent parts to make the cube with 60 % less seams

[@Lockbar]

Thats a very uncomfortable pillow.

[@MajorDrinkins]

Great stress test. You can really improve the skill by doing this kind of work. Great training.

[@JonMurray]

That cube was extremely satisfying. Awesome video as always mate.

[@ConnorHolland]

Thanks!

[@humdinger7275]

Impressed with that hose and those fittings

[@deucedeuce1572]

Even if I know it would never work... I would have loved to see those first one's unfold into cubes. I wonder if that's even possible. Like, is there any kind of weld that can withstand that level of deformation?

[@ConnorHolland]

I do think it will work if I made it on a larger scale, as the steel will be more flexible. The unfolding cube design works when made from paper or metal foil, the Mythbusters even made a lead balloon the same way

[@GWAYGWAY1]

I made two stroke expansion chambers like that, but the welds take a real pounding.😊

[@jiggasvr6]

Hi, can i ask what gauge plate are you using here , and what method are you using to weld the edges together? ...Thank you for the fascinating content...

[@ConnorHolland]

I'm using 1mm thick mild steel, welded with TIG

[@logancook8983]

would should try annealing the metal at different points in the forming

[@timberframe4646]

Nice!

[@ovalwingnut]

I've been taught that you can't put a round peg in a square hole. Your video just blew the WATER out of that theory Hey wait! It sill doesn't?.... We kid because we love! Thank you for the video. The effect is memorizing. Cheers from So.CA.USA 2nd House On the Left

[@grahamjones1446]

It's like a steel LIPO failure without flame's 😂

[@Enjoymentboy]

Interesting. Now do a tesseract.

[@xploration1437]

Please make more videos.

[@SufiRepublic]

Nice video, could you please tell the pressure produced by the pump, and tge sheet metal thickness? We would be very thankful

[@ConnorHolland]

90 bar pressure washer and 1mm thick mild steel

[@Siberian81]

Symbiosis of square and ball. I wonder which shape can withstand vacuum pressure? 👍

[@2k7u]

ball also square + ball squall 😎

[@lexvelema5576]

Any tips on how to connect the hose? I welded the nozzle but the tube melted so i had to cut it of

[@ConnorHolland]

I think I welded one tack at a time at low amps with TIG, with a wet cloth around the hose, and cooling it down after every tack

[@lexvelema5576]

@@ConnorHolland thanks hopefully it also works with 2 mm steel

[@ConnorHolland]

@@lexvelema5576 Yes I think 2mm will work fine

[@jamespayne8781]

One would suppose that mechanical stress begins to affect the welds as the angles change during inflation.

Было бы интересно узнать как изменится прочность швов если сваривать лазером?

[@rubberducki0406]

What is the purpose of this?

[@3Mwalker]

Brilliant

[@pef1960]

Well, that was a bust...

[@KinneKitsune]

Love the lead balloon fold

[@ConnorHolland]

That was my inspiration, a larger one should work, just like Adam & Jamie's one

[@seabassmastermatt80]

Shame about experiment No1 man. The pop was potentially epic!! Exp No2 a ball with corners it is then.

[@ConnorHolland]

It was close to working, just need to make some changes and try it again

[@firstsurugi5250]

Now paint it gold and put some question marks on it.

[@dogedog2447]

Cool

Try a dodecahedron

[@UNIVEGAMETALLICA]

Too much boom means too much air. This only properly works if you remove all the air. Air compresses and water doesnt.

[@stomis2346]

Put filler rod in your welds and it wouldnt fail like that...

[@IliadDreyfus-js9oe]

Those aren't welds, you didn't use filler metal

[@terryatpi]

It’s how dirt bike exhaust are made ?

[@2k7u]

metal cube pillow is my favorite

[@makaylabuckman7911]

Was it fun playing with that and spinning it?😊 I mean did I have a good balance...

[@ConnorHolland]

Yes it has a satisfying perfect balance while spinning

[@mcseforsale]

Final exam at TIG welding school!

[@Pikulev_Evgeniy]

Есть какая то практическая польза от этих опытов?

[@contessa.adella]

Why?

[@ConnorHolland]

Because I wanted to know what would happen

[@granofon]

Металл 2.5 мм аозможно надуть?

[@ConnorHolland]

Yes 2.5mm will work

[@ANLWhip1]

Now test it with a vacuum

[@jonathanshaw8868]

Now do it with compressed air

[@DanielLCarrier]

Now do a tetrahedron.

[@ConnorHolland]

[@robotnikkkk001]

....OK,THIS *WAS* ARGON WELDING INDEED OR KIND OF THAT SO I GUESS THIS WAS THE BEST OF WHAT WAS POSSIBLE ............STILL KIND OF SAD THAT PLAN A DIDNT WORK THIS TIME

[@thomasmica2856]

Сфера вписанная в куб

[@djwindkind]

Noice!

[@6B8RX]

It's a Borg cube after bean burrito night!

[@josemanon6295]

Funny

[@SoylentGamer]

These videos scare me, injection wounds are really horrible.

[@copescale9599]

looks like a Samsung battery

[@CRAZOR6]

Not a cube.

[@ZappyOh]

Why?

[@ConnorHolland]

To see what would happen, is that not why you are here also?

[@xploration1437]

Somebody hates learning…

These are ferrigami art objects. Good work.
