Mount for the hydraulic jack.. Turning it upside down.
Wanted to add bigger jack to my press.
To get most of the pressure to the small area, i decided to turn the jack upside down.
This way i can mount hole punching and stamping dies directly to the cylinder of the jack.
In use:

Takes about 10 seconds to assemble / disassemble.
Springs are surplus from trampoline. Bigger holes drilled with a variable wood cutter, with diy hss blade.
Used cheap 8 ton jack that was sealed with welds.
Actually this should work with "any" jack, without need to open it.

Jack mount is locked on its place with two M8 screws. Lid in front is weld to the mount...

Latch on the back is bolted to the press frame..

This is the reason why i welded similar plates to the bottom and upper bars of the frame..

I can use same dies with both jacks.. when i need to bend thicker materials i use bigger jack..
With thinner ( <5mm ) i use smaller one, wich is more accurate and faster to use.

I used surplus cutting fluid container as a oil container,
for mounting it to the press, i used clamp that's originally intented to connect flashlight to the welding mask.

And why i originally wanted to add this jack to my press.. i had this idea in firts place when i made the original frame, but no i needed it. So, i made it.
For stamping sheet metals. These are going to be reflectors for small leds. I got idea from Tony Foale, i decided to place dozen small led spotlights to my shop where i need more light.

Fitting. Didn't find suitable, so i made it from bigger one, cut the end out and welded piece of 6mm ( hose is with 6mm inner dia ) thick pipe to it.

Cap is made from a bolt. I filed groove to it, it allows container to breathe.

I used this hose in that first version. Now i changed it to appropriate one...
Attachment 23351
But at that time, i had any hose and stores we're closed. So, i improvised.
I peeled it from electric cable. It worked nicely that time i used it, but i decided to change it before it breaks.
