Scrap metal jack, do it yourself. A simple scheme that can raise a lot.

After starting construction with your own hands, it is impossible to stop. And I want to "create" in all directions.

I continue the theme of reviving my change house, which is already about 20 years old. The first thing I decided to start with was the foundation. It will be made from old fence posts.

I wrote about this in detail in these articles:

Scrap piles. The fence posts that have rotted in the ground for 20 years will now be the foundation.

I use waterproofing to protect metal posts from corrosion. Much safer than just painting.

The next stage is the rise of the change house.

The plan is this:

• I raise her on temporary supports.
• I install the pillars of the foundation, and do the strapping.
• I lower the shed onto the new foundation.

It's simple, the main thing is to solve the question: how to lift this "iron box"?

I didn’t want to buy a jack for this, because later it would just stand. Automotive, I'm not sure what to handle (I don't know how much my construction weighs.

So I decided to experiment:

Remembering, all the same ordinary, car jack, whose principle of operation is based on a conventional threaded stud, I decided to create something similar.

• Hairpin M20, left over from the attachment of the Mauerlat on the aerated concrete walls of my house (if interested, you can read about it here).
• And nuts to it, 4 pieces, welded together to increase the thread support area. The more nuts, the more powerful the jack.

Then we take a few parts from a pile of scrap metal in the yard to complete the construction.

✅ From this, you need to create a support for these four nuts, on which the entire mass of my change house will press.

• I welded 4 stiffeners to the nuts.
• Motom bottom plate with a hole in the center.

• And he put all this on a scrap from an old fence post. It is needed so that the hairpin has where to go.

That's all...

No calculations, no measurements, all by eye. And how he can cope or not, with his task, read in the following articles.
