Now my curiosity is really peaked for the purpose of this build. It's gotta be something really cool 😎.
LIke my thoughts also...
Maybe it's just test piece for larger project.
It has almost twice the pushing power then a normal double acting piston. , but it's allot longer. Can be handy in some situations where you need lots of power and don't have the space for a bigger cylinder.
????????😮😊
From design, editing, to the final product, there's never a disappointment. *Well done.*
И что это было?
Aw
Aw
Aw ja
ពួកែធ្វើបូមណាស់សូមសរសើរៗ
Дружище, давай что-то более утилитарное, как раньше. Транспорт хорошо заходит.
A work of art. Made by a master of his trade. Thanks for a great video.
This channel never disappoints
You make it so smooth that it looks easy.
Did you hone the cylinder bores? A good dingle balling then a flat hone. Keep those seals intact for longevity
Those seals will be in shreds in no time.
That's very impressive, and relaxing to watch! Great Job and Craftsmanship.
Fantastic work, dude! Really impressive!!! 😃
Stay safe there with your family! 🖖😊
Great work. Very inspiring!
Great job Michael 👏👍
Amazing!! Great job I didn't want the video to end 😂
Nice work, and we rarely see these homemade. We shared this video on our homemade tools forum this week 😎
Great project and video.
Thanks for sharing.
Great job, thank you brother. You are so talented
Very nice in-depth video on how you made this
AWESOME as always!
Wow....great job, congratulations!!!!
Always the best 💪🏻
Awesome tool. Thanks Ron
Amazing skills 👍
Very nice. Thank you for sharing
Did you cut out the part about honing the inside of the cylinder because I can't see this ram actually lasting very long before the seals wear out and start leaking passing over a standard inside pipe finish...
its a hydraulic cylinder tube, is already smooth inside.
@@petrosant123 because welding doesnt distort metal.. yeah… best practice is to check and rehone the barrel
I bet it would last long enough for what he is gonna do. And if it doesn't more content for us then.
@@Tgiles13 lol of course it doesnt.
There is so much more wrong with it. Did you saw at 10:30 how he had to bend the piston rod to assemble it. It will start leaking really soon. Video is looking nice and people who don't understand machining are liking it. But this is not the right way to make hydraulic piston. Most of it is wrong.
Very interesting quality videos 👍
From parts of steel to a functial product..👍🏻👍🏻👍🏻👍🏻
Beau travail très sympa
Wow! Good job! I build my machine with pneumatic drive
Omg. It's the best sample how make some simple thing to very difficult.
BEAUTIFUL!!!
Wow great build
Good job mister well done
nice work 😁👍
Always amazed me......
something tells me you did this on your lunch hour!
Очень красивая работа!
You are very talented person
Excellent work. Oh, I almost forgot. Congratulations, Happy New Year and welcome to 2023.😀😀😮😮😃😃🎆🎆
Nice work
Nice job
The best!
Belo trabalho
Awesome products
Great work
Nice. What is your fallback colour in case you run out of that green paint?
Prob has a closet full of the shit since its such a big part of his brand.
Congrats on the job.
Did you use stainless steel or carbon chrome?
Request: can you do the same but with steering rack and steering pump powered by small motor for DIYers?
Безусловно очень аккуратно и профессионально. Однако отсутствие зеркала самого цилиндра вряд-ли позволит ему долго прослужить. Момент с ханинговкой либо вырезали, либо его просто нет.
Сердце кровью обливается когда сначала делают мехобработку и потом сваривают детали
Good job
the story of the overly complicated bong
Very good 👍
انت مبدع
perfect 👌
Muy buen trabajo y excelente presentación. Sólo una pregunta, ¿la conexión es en SERIE o en PARALELO? Muchas gracias.. Felicitaciones!
It's parallel
Great!
Tuan saya sangat senang sekali dengan adanya video ini dan saya sangat terbantu dalam pekerjaan saya atas adanya video ini dan saya sangat berterima kasih banyak 🎉🎉
next project. you should build a low cost mechanism to raise or lower a desk. maybe air hydraulic , electric gears, old school industrial crank wheel. that would be awesome
make it in style of citroen c5 suspension so it floats :O
Don't forget about their extreme workbench build. Perhaps this could be an upgrade for this. ruclips.net/video/38yPR25VSw4/видео.html
Сделай механическую беговую дорожку
Легко и просто и по красоте
Your al projects are amazing,please make model jet engine even I also want to make it
very good
Great job! Congratulations, a question inside the tube needs to be given some kind of finish, or polish, what kind of tube did you use. Hugs Vicente (Brazil - BR)
I have honestly never seen a dual piston hydraulic cylinder used anywhere, so its gonna be real interesting to see what you have in mind here.
because its useless
@@blackdaan в рулевых усидителях грузовиков и автобусов не редко используются. Вряд-ли бесполезно
@@blackdaan yes and no, it will make double the force of a single piston in this case
@@blackdaan Such hydraulic cylinders are used where a large force is needed, but a sufficiently large cylinder diameter cannot be used.
In this particular case, bad seals are used between the first and second parts. the oil will overflow from the second to the first
@@motomaniakpl diameter is needed for force. Double cilinders will increase the speed by 2. Bot the force by 2
Excellent job. But why compression fittings?
Just for testing and not to make a mess with hydraulic oil.
Somone should show the hacksmith this...they have been having alot of issues with hydraulics and would love this!!!
nice!
isnt the UN-seal leak to she otherside, cause it can handle preasure only from direction of the V-grove. What for you put that dustseal in there at the middle?
Nice Jobe i love your videos 💪👑
397th viewer and the 9th posting a comment!! Let’s go Make it Extreme!!
I find a hollow one is very useful
Good job, but just one thing the chamber of the piston will not be ideal because the inner surface is not smoothly so it will damage the seals in small time
I thought the same thing, but we can only assume that a man that can build hydraulic cylinders from scratch knows that and probably polished them off camera.
@@darylcompton3433 yes I agree , really it's great job
My feelings as well about not polishing the cylinder bore. Otherwise a very interesting build. Like many have asked what is it for.
@@darylcompton3433
You know what happens when you ASSume.
Another comment mentions that the “pipe” material he used is actually material made for hydraulics so it’s already the right surface inside.
I ASSume that’s correct. 🤷🏻♂️ I certainly can’t dispute it.
No seal between the 2 Cylinder sections, going to leak. Interested how you took out the weld seam in the tube too
Seamless tubing bud
The "gland" between the two cylinders is the seal.
Do you actually gain more with this? Looks like it would be more economical to have a larger diameter cylinder than to have a cylinder twice as long with half the stroke unless you just gain exponentially with it? Just trying to visualize where this would be best beneficial is all. I could see some machinery benefits with diameter space savings, but again losing a lot with length.
Did you use seamless pipe or tube? Honed or not as doesn't look like honed pipe from what I could see. Maybe isn't that big of deal. Neat build! Never studied hydraulics in detail and makes sense for a more compact diameter size.
@@illudedCeption its a hydraulic cylinder tube, already honed
@@illudedCeption 100%, i know the guys
@@illudedCeption the know what they are doing, they would not use wrong materials for this
@@illudedCeption Chill dude, want me to give you the specs of the tube they used? I can do that. its actually welded cold-drawn polished steel tube.
The cylinder should be skived and burnished to provide a suitable surface for the seals.
Ok
Great build but why? What advantage over a suitably sized single piston ram ?
Is pipe polished inside? How long gasket can work if not?
I was wondering if honed or not and if tube or pipe since looking online appears both tube and pipe can be used for hydraulic applications.
I’m guestemating but the total surface area increased by doubling up the piston that way was only about one third more not the double you’d expect. This would be more of a benefit in retract than push as it is truely double in that direction.
Considering all the extra piping it’s doesn’t seem like much of an improvement in size reduction over using a tube twice the diameter.
I think if he uses the same hidraulic pump, it doesn't increase the power.
@@tareksma1 . The pump size only really matters if it is too weak for the task.
Well. Clearly if you do the math then 2x diameter is MUCH more than 2x the volume so in a Captain Obvious way you’re correct. 🤦♂️
@@Crewsy . It’s not so obvious.
The force is exerted on the surface area of the piston, the larger the area the greater the force, however on the second serial piston the surface area is diminished by the piston rod , you would actually get more force out of two parallel pistons than out of the serial setup.
There is something that I almost completely forget about how to calculate the force on the second piston however.
I kind of remember something about force being slightly greater than the total surface area of the piston with the rod taking up the middle of it. It is less than piston with the full surface area available but more than only the available surface area would suggest.
@@anomamos9095
You’re overthinking it. It’s obvious that a 6” circle has a much greater surface area than two 3” circles so doubling a cylinders diameter will way more than double its pressure.
You specifically mention “using a tube twice the diameter.”
Awesome skilled video. Not everyone can go all vid with no speaking😅Is it destined for use on some massive machine???ThankQ.TkEZ>UK
Make a double extending hydraulic cylinder next
Hands up if you remember the death metal videos ? OG’s where u at ?
супер ! 👍
Хорошего токаря щас братва с огнём не найдёшь, а этот молодец
Good ii boss MIE💪💪👍👍👍✌️✌️
En cual parte del video realizó el pulido interior del barril (cilindro)‼️⁉️❓
listen to the boss,,,,, don't forget to stop by for black coffee together... goes duit and goes natural so that you will increase your enthusiasm for work and add brothers thank you very much
The wife, At last, something I can use".
Did you feel the Earthquake happened in Turkey a week ago ?
NASA should hire you
I like it but what kind of application would need a cylinder like this?
For example, if you are limited with space in side direction, yet need bigger force?
#makeitextreme More power with smaller cylinder diam? Or did you mean speed? Because of higher velocity from flow?
Just wondered or am I wrong?
Always enjoy your videos thumbs up from me
Is that a 6 jaw chuck there?
Very nice, as always. But I don't really see the point of it, especially without a description of how it works. Thanks though. Regards.
Are you from GREEC
What does a double piston ram gain over a conventional ram please?
Double the surface=double the force applied on the ram.😏
@@jocelynbutty thank you.wouldn' it be just as easy and cost effective to use a slightly larger ram?t
@@jocelynbutty not double, you need to retract the area of the rod.
@@philleeson7835 I think that was the point, maybe you need a really thin cylinder for some reason, this is one solution for that. Not sure he has a practical scenario, more like a proof of concept. 🙂
@Jocelyn Butty but it's actually only double the surface area in the retracting/pulling direction and like 1.5x in the other(ruffly without knowing piston and rod sizes). The second piston has the rod on both ends, giving it less total working surface area.
Do you have the sectional drawing of hydraulic cylinder and its parts name?
Will it be more powerful because it has double pistons and if so how ?
It is like having two pistons.
The hydraulic force is the product of pressure x area. In this cylinder are two separat volumes so the area from the piston is nearly doubled (second area is reduced by the piston rod)
It's essentially pointless.
It will be almost twice as powerful than a single piston with the same diameter cylinder and piston rod diameter. It will also require twice as much flow, so operate at half the speed as a single piston.
@@EVLS10 no its not
What's the double piston do that a single cant?
Please provide the name of material and gread sir
Like always excellent craftsmanship, but idea don't have too much sens, at least for me : you add double the length, instead couple mm of piston radius, if shaft seal start leak you lose pressure in bouth cylinders any way and you triple connections (points of potential leakes) and at last, because in secound cylinder you have shaft, power gain in extend cykle is negligible ?
Could that design improve power on a mini digger?
The force Output will be Higher (its Always pressure*surface area) but you need more Hydraulic flow. Its only Advantage over a bigger cylinder is the Formfactor. You wont gain anything by using this on an excavator comparing IT to a regular cylinder with the Same surface area of the Piston (pressure*surfacearea).
The only reason to do this is to get more power from the same pressure when you have cylinder diameter constraints. On a mini digger, this would be pointless because you could get the extra power needed by going with a slightly larger diameter cylinder off the the shelf.
