Introduction: 16 Tons Hydraulic Press

Press thing is not the first need, but many are useful in the household. Especially people who like to tinker in a garage or a workshop. While making it very easy.

Step 1: Make a Foundation

For the base we use the channel.

Everything is simple, we weld a rectangular structure with movable part in the middle. Base dimensions 105х55cm, you can make your size.

Drill holes for the choice of height, weld the legs.

Step 2: Make Hydraulics

Our task is to make the jack work upside down

Get a stopper from a jack, drain the oil. Unscrew the big nut on top of the jack, remove the cover, see two holes, we are interested in a hole near the piston. Through this hole, oil is pumped into the working cylinder. It is necessary to make so that oil acted in a cylinder when the jack is turned upside down. For this, I used a hose from a disposarle infusion set. Fix the tube with glue and collect the jack in the reverse order. Fill the oil with a syringe back into the jack, maybe have to add more oil, it's OK.

Step 3: Finish

Make a platform on which we mount a jack. Weld to the plate eight nuts, four on each side. Bolts and plates are fixed in our base. Jack can be moved left or right.

    I am surprised the jack works in that setup. Most commercial presses set the jack in it's up right position and use a large diameter rod that is pushed down when the jack is pumped up. I've been using my commerical press for decades without any issue. You also need some way to collapse the jack when you release the pressure. Most use a couple springs for that. JMHO

    I agree, the springs will be useful. Thanks!

    A similar press on Instructables (with jack the right way up) used bungee cords as the reverse springs.

    I made one a few years back. To keep enough oil in the jack, I removed the rubber fill plug and threaded it for a 1/4" NPT fitting, and used an old lawn mower gas tank as an oil reservoir. Used 2 old car hood springs for the ram return mechanism. Worked great.

    Why go to all the trouble of mounting the jack upside down ? The one i have built is very similar to yours but has jack at the bottom, pressing upwards. I find that this way works fine.

    is hydraulic Jack working well in vertical position I have little doubt on that.
