Thank you very much Jon, and the ones that voted by clicking thanks button.

This build will be continued.
At the next week or after that.

Made a mount for the vise.
Material is 10 x 50mm steel.

It connects to vise with four M8 bolts.

I have couple ideas for motorising the jack.
Allthougt, i don't want to build whirlygig around it.

Here is the idea about the first version.

Unless some modifications were made to the jack you are going to have problems with it operating, to use a jack on its side the pump has to be on the bottom, or the bottle has to be over filled.

I use this same way that i have used earlier.

This time extra container is integrated to the jack...
( Sounds weird, but that's what i planned)

That would work.

Extra container for the jack.
Now it works better on sideways.

Material is 1,5mm stainless steel.

Short clip about testing with modified hydraulic jack..

Jack is still unfastened, that makes using little tricky. Also handle is too short, and with little too small diameter...
But it works like expected. Now i can go forward...

Extra container is weld to the original container trough the hole, where i later placed the cap fitting.
This gives little extra room for welding. Cap fitting was weld on its place after containers we're densely weld together.

your jack looks like a 2 ton. A normal 6" screw vice can, at a push give about 1.5 tons. The idea of the saddle tank is a good one. If you want to increase the output of the jack one method would be to decrease the size of the pump piston and cylinder. (All jacks seem to have the same size pumps, the load piston being increase in area to increase the output, so conversely, a smaller piston would deliver more force with less effort).

Thank you Hans. I keep that on my mind.

This version was for testing the idea. I have three different versions on my mind that i want to try.
Smaller jacks are cheaper, i use them for making prototypes.
When i found the best option for me, i make bigger version from it.
