Greetings to all lovers of homemade products and those who just looked at the site in search of useful tools in the household, garage, workshop, which you can make with your own hands from scrap materials. In general, hello to everyone who loves tinkering. Today I want to bring to your attention an option for making a vice that will not interfere in a carpentry or locksmith's workshop. Yes, there are many options for such a device on the site. But the author equipped this vise with a hydraulic drive, in other words, he installed an automobile jack instead of a standard screw. Maybe such options are familiar to many of you, and someone will say that it makes no sense to install a jack on a vice, but as they say – how many people, so many opinions. In my opinion, this version of the vice is very convenient. If you are interested in the idea, you are welcome, read the article and take notes. Below there will be a video from the author on the manufacturing process, so if someone is too lazy to read, go downstairs and look.
* sheet metal of various thicknesses from 4-5 mm to 18-20 mm (choose at your discretion),
* metal corners (section not specified, also select individually),
* round metal pipe (the author uses it for reinforcement),
* four bolts,
* two rigid steel springs,
* paint for metal in cans.
* welding machine, < br> * drilling machine,
* grinder with cut-off wheels,
* marking and measuring tool (square, mark, ruler),
* magnetic squares for welding (optional, but desirable).
First of all, the author makes the base of the movable (clamping) jaw. To do this, he uses two corner pieces. Their length is selected based on the dimensions of the jack and the stroke of its shaft, plus the total thickness of the two jaws. The author combines these corners on the shelves, installs magnetic corners and welds both parts, it turns out something similar to a channel. In principle, you can use a channel, if available.
Next, the author prepared a round timber of sheet metal with a thickness of about 10-12 mm. The diameter of the disc, at the top, is about 25 cm, maybe a little more. He installs a previously prepared base on it, and on the sides applies two more parts previously cut from the same corner. Welds them to the disc.
On top of the edges of the welded corners, the author places a metal plate of the required size and also welds it to the edges of the corners. All seams are processed with a grinder.
At this stage, the author proceeds to the manufacture of the first clamping part (stationary). Takes two plates of sheet metal of the same size, roughly the same thickness as the disc base. The author installs them vertically on the previously welded corners using magnetic angles, as shown in the photo and welds them.
Then he picks up two plates of sheet metal with a thickness of about 4 mm and welds them to the plates parallel to each other. At the final stage, a narrow plate is welded on top. All seams are processed and cleaned.
Next, the author removed the movable base, which he had made at the beginning, reinforced it from the inside with two pipe sections and, in the same way (as in the previous step), welded a second clamping jaw to it. I also cleaned and processed all the seams.
Since our vise will be hydraulic, and it will be set in motion, they will be with the help of a jack, it is necessary to install an emphasis on the moving part under this tool. Its author cut from sheet metal with a thickness of about 14-16 mm. Then the author welded this part to the protruding end of the moving part, while installing the jack as it should stand.
The author reinforced the emphasis with two metal kerchiefs (metal thickness about 5-6 mm), welding them, as shown in the photo. < br>
Now it is necessary to provide for a reliable fixation of the drive (jack), but at the same time, the mount should allow you to remove the jack in order to use it for its intended purpose. The author tries on the jack in its place and selects (manufactures) two simple parts – a ring made of a metal square (section about 5×5 mm) and two corner-shaped parts from the same square. The ring has an inner diameter equal to the jack shaft diameter. Having strung the ring on the shaft, the author brings an emphasis to it.
He sets the corners at the corners of the supporting part of the jack diagonally. All details are welded.
At this stage, the author provided a return mechanism, that is, when the pressure in the jack is released, the shaft together with the moving part will return to its original position. For this, the author used two springs. To fix them, the author welded two bolts on each side. I fixed the springs on them, and so that they did not come off, I strung washers on the bolts and screwed on the nuts. To protect the springs, the author welded plates over them.
So we come to the final part of the process. At this stage, the author has made the overlays, which should have any vice. Their author was made of thick sheet metal. Cut out two strips of the desired size from it. Using a square and a marker, I marked them on them. As shown in the photo.
Then cut grooves with a grinder along the lines .
Finished pads, folded grooves inward, installed between the clamps and welded on three sides. I cleaned all welds with a grinder.
hole on each side, for mounting bolts.
At the final stage, the author painted the vice in two colors with metal paint from cans. After complete drying, I checked the performance and slightly tested them. He demonstrates this in the photo.
