We Turbocharged Bottle Jacks by Closing the Pressure Valve!

We tested how much bottle jacks can lift if you close the pressure valve. Don't ever try this at home! Closing the pressure valve will jacks fail in dangerous way and going over the rated capacity makes them dangerous. All tests were done in bullet proof bunker by profesionals.

"Do not adyoost" I love you guys...

[@jasonbirch1182]

No idea what that meant until shortly Into the video 😂🤣

​@jasonbirch1182 I figured it out immediately cuz I'm Scandahoovian

[@xploration1437]

Adjust, not touch. Get the quote right at least.

[@yayweredoomed]

He says “do not adyoost, don’t touch, and that’s, like, promise of adventure for us” so your correction is not correct either.

[@Beyondthepress]

It's quite late here so I won't spend too much time today on the comments. Been long day already but hope you enjoy the video! I have been wanting to test this out for a long time and now finally got to do this

[@surplusdriller1]

Perkele. fill an empty hydrolic sylinder with sticiometric amounts of hydrogen and oxygen plugg it and compress on your press as fast as possible. greatings from Norway

[@neshpro6521]

I’d like to see your hydraulic press hose hooked to the bottle jack and test its strength and durability maybe smash some stuff with it!

[@Tibersun]

I would likely buy some dice if they were more than 6 sided.... I have many friends that play DND and I think that would be a good gift for them

[@marksmithson1414]

This was still an interesting video Lauri and Hanna

[@matthewellisor5835]

I did enjoy but I would love to see a teardown of the 4ton. See exactly how it failed

[@declanb6985]

Love the "any amount of fuck-around here is going to be dangerous."

[@ronblack7870]

the pressure cylinder is inside the outer cylinder. there is oil tank between the 2 cylinders so you won't see anything break.

[@stevencooper2464]

Most likely, the hydraulic cyclinder ruptured inside the reservoir; the oil is just circulating back in to the reservoir.

[@benchpressguy]

We did something very similar at my old job. We found an old hose laying around the shop that just so happened to be the same length as the current pressure hose on our small press machine. We replaced the hose knowing that it had to be weaker than what we took off but we didn’t know exactly how much weaker. We put a weight on the press button and ran. Sounded like a tire exploded which is what we told the boss since the tire machines were like 20 feet behind us.

[@rachelfrancis1990]

“Any amount of fuck around would be dangerous” would be STELLAR merch.

[@WoodworkerDon]

As Lauri wisely said several years ago "do not never modificate your tools." 😆

[@android01978]

Translation: always modify your tools.

[@davideimperati1802]

Probably they have a burst disk somewhere in the circuit so that it won't go bang is someone tampers with the screws. Liquid filled vessels are boring. They stop moving as soon as the vessel cracks and pressure is relieved. For a bigger effect you shourl try with a pneumatic pump. Air is compressible and it stores quite a bit of energy.

[@ib.i.b]

I like the "Fuck around and find out" method too!

[@DarkZodiacZZ]

I love how you incorporated the "fuck around and find out" into the lecture. ❤

[@valtsu56]

The real danger in overpressurizing a bottle jack is not explosion, and metal pieces flying around, and killing you. The real danger is, that normally you are lifting something too heavy with it, and when your jack fails, that heavy thing crashes down, and kills you.

[@Bagline]

You bought that expensive camera holder robot arm, use it to pump the jack remotely.

[@pastaalalamborghini]

My brain hurts thinking about how much programming that would probably take

[@RabbitsInBlack]

@@pastaalalamborghini Actually it's very simple.

[@howa08]

​@@RabbitsInBlackIn some aspects yes, but, I have a simple CNC machine and programming basic things still takes time

[@chitlitlah]

@@pastaalalamborghini Once the robot is in position and attached to the lever, it only takes two commands within a for or while loop. ABB robots have a MoveC command to move the tooling in a circular arc, so you use the command to move it one way, and then just reverse the parameters to move it the other way.

[@hhg7832]

I completely forgot about the robot. I was going to suggest using the press.

[@Zoroff74]

Soo... You guys just demonstrated that we can "upgrade" our bottle jacks without them exploding, I might interpret that as a recommendation, hehe.😁

[@IridiumRedTheOrigina]

Am guessing relief valve is something like a screw on top of a spring on top of a ball/check valve. Screwing it in sets the preload on the check valve, so at some level of force (a certain psi) the valve opens up, allows flow back to tank. You have a machine shop, how about you take all of those parts out, and make a solid plug to thread in? Something that will physically plug the relief port? Might even be as easy as replacing spring with solid plug. I bet THAT would do something. I'd like to find out how that works :)

[@bevis226]

12.8 ton out of a cheap 4 ton jack is quite impressive lol. I cranked the relief valve in 2 turns on the cylinder in my Mower jack. Before it was having trouble lifting 300lbs. Afterwards it easily lifted 900+lbs. Did have to reinforce the metal at several places because it was starting to bend up like a taco but it will lift much much more than it was advertised to lift.

[@mircomuntener4643]

Today I learned that bottle jacks are adjustable, just pop the 'do not adyust' cap out of the turbocharger port, bottom out the screw, and back it out a half turn.

[@altern8tive]

I think someone has been adjoosting the F-bomb threshold valve on this channel lol

[@danielgoodman3578]

Thanks for teaching me what the "DO NOT ADJUST" adjustment is! That was neat to learn! :)

[@davidotto7666]

Just want to say thank you for keeping it real like with the swearing and all that you keep it down to earth that's what's up that's what real people do they talk how they feel comfortable and hey I'm glad you're doing how you feel comfortable brother thank you for keeping real

[@meJaso]

It would have been neat to see how close to spec each relief value actually triggered at before adjusting, then max it out.

[@ml.2770]

And now we are going to find out what we are going to find out.

[@Jo-the-fixer]

They have come along way from when they started. Your FAFO way of saying it's great

Got to love a video with "DON'T DO THIS!" stamped across the thumbnail.

[@yld244]

Disappointed we didn't get to see you squash the shit out of those jacks till flat 😂

[@tslim250]

i would definitely buy some titanium dice from you guys. can't wait for that!

[@steves7189]

Love watching you guys! Thank you for the interesting videos. Good luck with the dice!

[@garymcdonald6529]

Promise of adventure, let’s go all the way, FAFO, famous last words! Love it!

[@ruger8412]

Its designed not to spontaneously disassemble. Its a safety feature

[@fritz46]

They probably sell the 4 ton jack as 6 ton and 8 ton for more money, with just a different valve setting.

[@epajarjestelmainsinoori9037]

Exactly. No maybe even for more money but a different brand. I have 2 exactly same cheap jacks, one with 4 ton label and one with 6.

[@rjgaynor8]

Those jacks have rings that keep the piston tight to the cylinder. They are a secondary fail safe. They will fail before the metal fails.

[@ludecom-cz1wz]

DO NOT, the most dangerous words to tell a human.

[@pierrelaboom4026]

I love when a channel highly recommends turning the ,"Dont turn this screw" who needs a bigger one," majic screw makes it bigger"

[@marcliebich9166]

"This is what happens when you fuck around with the pressure"... love it!

[@mojojomo6750]

Not much happens, as it turned out! It would have been nice to see it explode, or at least to have had the jack cut open to see what had failed.

[@NOTNOTJON]

Failure point was probably an o-ring inside. Those things are made to spec and don't often fail, but when they do...is bad.

[@Barbaratio]

thanks for showing how to overclock my bottlejack.

[@mickellis8747]

I'm disappointed you didn't pull the smaller jack apart so we could see the split in the cylinder.

[@andybobandy641]

Aaaaaand there's another T shirt. "Don't Do This". Perfect.

[@reaganpm7968]

i appreciate you being patient with the fact that your girlriend/wife has less understanding of english

[@martinpanks992]

Try and do it the other way round, pump the jack up to the press and measure its force that way you can easily re calibrate and reset the screw on the jack.

[@jbsthegamer]

Take the spring out of the 20Ton bottle jack and then tighten the screw and make some sort of metal rod to push the valve closed

[@chrongen13]

"Any amount of fukk around" 😂 I wish this guy was my coworker, he'd make my day a breeze 😂

[@douglasmayherjr.5733]

Appreciate the Videos. I was hoping for an explosion. Your commentary is always great. Thanks from Michigan.

[@jasonbirch1182]

The outside is just the resovior. The internal cylinder on the first one probably split.

[@MikkoRantalainen]

I would guess the o-ring simply snapped and the piston started to leak.

[@cmsracing]

Take the spring out and install a metal rod in it's place to fully lock out the bypass valve.

[@royb.1441]

I definitely learned a lot - thank you!❤

[@robertwest3093]

Do not f around with it so let’s see how much we can f around with it. Any amount of f around could be dangerous. 😂😂

[@disturbedmaynard3873]

Sorry Laurie, I have the nicest dice. They are made of natural stone. But if you can make some metallic dice that don't get all dinged and scratched up, that would bee cool.

[@Nbomber]

i did this, and bent the frame on my cheapo 6 ton press. the jack has never really worked right since

[@thezen8021]

Fun video guys, i like it

[@ZMAN_420]

DON'T F*** AROUND AND FIND OUT! 😆😅😂🤣👍🏻

[@johnbennett1465]

There is a nice robot arm right there. So how about using it to "manually" pump the jack. This would allow checking how hard it is to actually blow yourself up.

[@johnbennett1465]

Edit: the jacks are too safe 😥. Oh well, something to keep in mind for the future.

[@epajarjestelmainsinoori9037]

This is an excellent idea. You could see if the lever can handle it. Or the lever you can always replace with anything, but the lever base.

[@_Dimon_]

That was exactly what i thought. Like, you have a nice robot arm right there, why not use it?

[@jgrenwod]

It won’t “explode” unless there is a gas compressed inside. If properly filled with fluid (fluids don’t compress) and the air is purged, something will break but an explosion won’t occur.

[@helpermonkey6641]

test antique jacks against new jacks. bottle, floor, screw jacks

[@BrianLyod-nj1vg]

You know so many mechanics have played with that screw know I know the outcome x

[@TrabberShir]

What I learned is that this is a lot safer than I had assumed. Project un-blocked.

[@epajarjestelmainsinoori9037]

You could put washers or something in between the adjustment screw and spring and ball (or just the ball). In anycase good to know that a few turns of adjustment is perfectly fine 😂.

[@lauxmyth]

I like the adventure. ‘Not optimal’ indeed.

[@rastislavzima]

I have started to learn Finnish so now I understand the roots of pronanciation "hudraulic sustem" 😁

[@V00D00M0NKY]

this should be the motto of this channel "we fuck around so you don't have to find out"

[@gabiold]

Probably the piston seals or the piston itself broke in the smaller one. It is also possible the the cylinder wall broke, but you can't see it as the outer wall is just a shell, that's where the oil reservoir is.

[@jessicamcmillen5517]

you want some vodka

[@irishpsalteri]

This is great.

[@LouMihniak-kk3xb]

If I were a jack manufacturer, the label on the pressure relief valve would say, "DON'T FUCK AROUND WITH THIS!"

[@dillonwarman7769]

I remember in your early days you were taking suggestions from us in the comment section i said bottle jack and the next video it was there still to day your doin the bottle jack

[@arcadeuk]

When you ask your girl "How much we should fuck around" And she replies "A lot" 😂🤣

[@truthpopup]

It would be funny if a bottle jack actually said "Do not fuck around with this screw."

[@nicholasfrank2428]

Wonder if one was to lift the cylinder all the way, and somehow add more oil to the system. Might just blow out the "holding tank" but still look cool!

[@android01978]

What I got from this is you can increase a 20t bottle jack to 50t and it won’t explode. Good to know!

[@CommunityGuidelines]

Will the Kickstarter metal dice have perfectly machined, razor-sharp edges?

[@philipstephens1825]

Loved it 😂❤

[@Imnoexpert69420]

You need to figure a method for making a set of dice for DnD. Have fun figuring out the program to CNC the d4, d8, d10, d12 and d20. You can do it.

[@francesray6465]

Remember that song by Electric Light Orchestra (E.L.O.) called Don't bring me down? Yeah well now Don't FK Around keeps playing in my head while I try to lift my house with a prybar and a jack

Don't bring me down, Groos 🎶

[@fredmorton1631]

I would like to see soda syphon Co2 cartridges in the press.....He! He! He! He!

[@JoeVanGogh]

I would love to buy all the dice I can but atm I don't have a lot of extra money so depending on the price and or how long you have them available I will definitely be interested in the dice!❤

[@justskip4595]

Get a long enough lever that you can pump it through a almost completely closed door. Just enough for lever to move up and down.

[@billagedad1]

You should disassemble the pressure relief and put in something to plug it. Then hit it

[@sinformant]

"How much shouls we fuxk around" "alot" 🤣

[@TRLC]

If you wanted to pump the handle you could use your bunker robot :)

[@greenspiraldragon]

Keep going and crush the entire jack.

[@MrBradaz111]

to set the jack back at the right relief, wouldn't it be easier to lower the ram to the jack, then pump the jack, reading the presses pressure? rather that keep trying to squish the jack with the ram?

[@johnbeck177]

I would be willing to bet that the seals in the jack would blow out before any unscheduled disassembly occurred.

[@jonathandepenau3370]

You guys are the fucking best. Much love!

[@gregculverwell]

You could have just replaced the spring with a metal rod. I'm assuming that on the bigger jack, the screw bottomed out before the spring was fully compressed (good design).

[@woodcox0171]

Hell yeah, ask and you shall receive! ❤I requested bottle jacks in your poll for ‘what should we smash next?’

[@samhughes1962]

Could you do some kind of car brake pad test? Like hook up the master cylinder and see how much pressure is needed to brake the brake pads?

[@WoodworkerDon]

@Beyondthepress Lauri, when I come to visit I will ask to see your collection of useless cubes. Thereby rendering them useful. 😉

[@teardowndan5364]

The big bottle jack's adjustment screw must have bottomed out on its threads or spring bore, you'd need to pull the spring and replace it with a suitable size metal pin. For the small one, my guess is the main piston's seal blew out and is now leaking internally back to its tank.

[@billgaudette5524]

Maybe find a way to manually pump the jack while it's on the press and the pressure sensor is engaged. That way you can see how much actual pressure the jack is exerting; does it go above 20t when the valve is "closed"? Is there a way to modify it so that the pressure relief fails?

[@norfolknchance.500]

Would been good to see ypu blitz both jacks completely!

[@unlokia]

00:07 I thought she said “… and I have AR##HOLE” - I was gonna say that’s not a nice way to talk about him 😂

[@bikkiikun]

maybe, if you let the press continue to go down, even after the jack failed, you might get an explosion... at the very least you get some interesting crush.

[@AlaskanGamester]

i love your sweater Anni is it for men to ?
