For the manufacture of this device you will need a conventional hydraulic jack with one vertical rod (bottle type). Moreover, it is advisable to choose a model of the device, which is able to provide support rise to a height in the range of 180-340 mm.
You will also need three segments of a square profile of different lengths, which should be included in each other. Ideally, for this, use profile pipes with dimensions of 50x50 mm, 40x40 mm and 30x30 mm. Since the gap between the inner walls of the pipes is large enough, then between them it will be necessary to insert two plates of suitable thickness.
The main stages of work
From pieces of plates it is necessary to make an adapter for stopping the bottle jack - all the elements are welded together (how to make it, you can see in the video at the end of the article). After stripping the welds, drill a hole with a 12 mm drill.
In the head of the car jack, it is necessary to drill a hole with a diameter of 6.7 mm, and then we cut the thread with an M8 tap. Next, put on the adapter for the stop and fix it with a bolt. In the next step, we fasten the base of the jack to a rectangular plate by welding.
Next to the jack we fasten the sections of the profile pipes, which are inserted one into one (do not forget to insert the plates inside to reduce the gap between the walls). In addition, you need to install another stop from the profile 20x20 mm. The holes for the retainer are drilled in the side walls.
