- A commercially available bottle jack was modified into a hydraulic cylinder.
I am making a pipe bender using this cylinder.

Scrap, is the channel to make the machinery and tools in combination with a commercially available product.

You have no idea how much I appreciate your knowledge, thank you

Link for buy the large jack bottle used in video,please?
You could just remove the outer sleeve in this and make a clevis mount with the right thread? or is the body in the cheap jacks load bearing?
Нечего не забыл? Там две риски, для перепускания жидкости в верхней мёртвой точке, для предотвращения разрыва материала поршня и чтоб, крышку не вырвали при накачивании.
is the piston on the rod rotating? any way to disassemble it?
@blueworkclothes7384 This is very interesting, but what i would like to know is, do you put oil back in after this conversion, as you do not show this in the video.
Do you think its possible to connect two bottle jacks as when one of them goes down the other one goes up?
Aboslutely great and convincing but how do you get it go go downward afterwards? Through the pump???
Thank you for watching the video.
Open the relief valve of the pump to free it.
Then push it down by hand.
It is used in a mechanism that naturally lowers by the weight of the lifted object.
@@blueworkclothes7384 what sort of pump is that? Is that available to buy online?
@@blth14 Amazon he pointed it out.
Will this hydraulic cylinder work in an inverted position with your conversion?
Yes. The only reason that these don’t normally work upside down is because the lever pump sucks fluid in from the bottom of the outer cylinder.
I saw someone convert one of these to work upside down. They added a long tube so that it sucked in the fluid from the top. So it only worked upside down :)
This modification here completely removes the pump, which is the only part that has problems upside down.
@@gf2e I ended up tapping and plugging all holes (except the two needed for fluid transfer between the pump side and the one under the ram rod) with grub screws and red loctite. Doing it this way removed the need for a hand pump and adding an extra tube and was still able to use it upside down with an external air pressured hydraulic pump.
@@BigSidtrous Thanks for explaining what you did. I am thinking of doing that but with a battery powered pump. It’s a long term project, though. The off the shelf battery powered pumps are way too expensive, so I might try making my own by combining a motor and gear pump.
How does it retract
I'm guessing you reverse the pump. That would mean that its only good for transmitting power in one direction but it can retract.
The most common technique is to have a separate valve that lets the hydraulic fluid flow back into a tank. That doesn’t make it retract, but it lets it get pushed down.
I’m pretty sure that most hydraulic pumps aren’t designed to suck fluid back.
I required this any1 know the dealer plzs inform me
where can i get a pump like that? 7:49
I am active in Japan.
You can get it for around $200 on auction sites, but I don't know about overseas.
How will you release it.....
See other answers in this channel. The pump has a lever and he turned it before. You do the reverse. You can attach springs to lower it. This is not a dual-acting hydraulic pump. It is a single-acting pump so you need something to push the rod back down after you release the lever.
I need an hydraulic cylinder for my press project. I was thinking if i could get an 50T bottle jack and make this conversion since i have an old Nike pump. It still works upside-down because all the fluid now comes from the pump right? So no need for the pick up tube modification. Please tell me it's possible :D then of course some sort of a spring return setup.

isnt it rather a pneumatic cylinder now?
I think it can also be used as an air cylinder.
it uses oil so its hydraulic
Thank goodness you included that obnoxious music, or the whole thing would be so confusing...
