In this video I restored an old hydraulic jack.
I found it on a junkyard/metal waste. When I saw it I really wondered why someone would throw this away, because it wasn’t in a very bad condition, besides being very dirty.
As you can see it wasn’t too hard restoring it and making it work again and I am sure you guys could do that too! If you don’t have a lathe it’s not a problem. Pretty much everything I did on the lathe can also be done without one. Also sandblasting is not mandatory. So go on, restore stuff and save it from scrap disposal! :) If it can be repaired, why throw it away?
Simplified explanation of the physics behind hydraulic jacks:
Other than gases fluids are incompressible. The laws of fluid (liquid) pressure (Pascal’s law) says that pressure in fluids spreads evenly through the liquid. Example: If you put pressure on a fluid then there will be the same pressure everywhere in that fluid (if hydrostatic pressure is neglected).
Through the pumping movement hydraulic oil gets pushed into the jack cylinder and pushes the ram up, since the hydraulic jack is a „closed conduit“. The oil in the jack can’t be compressed (like air for example: compressed air), so it has to push something away to move. It’s kind of the same principle of a syringe.
If you wan’t more detailed info just write it in the comments and I will try my best to answer your questions.
The work on the project took about 30 hours (inclusive filming) plus about 18 hours of editing.

I hope you will have some fun watching the video! If you have any further questions on the process, tools, material, zinc plating or else write a comment, I will try my best to answer your questions.
I hope you liked the video! Thank you for watching and feel free to leave a comment and subscribe if you liked :)
