DIY Socket Wrench
What is needed Tools:
- - arc welding machine.
- - angle grinder.
- - other tools (file, metal brush, hammer ...).
- - a small metal plate with a thickness of 8 mm (probably thinner as well,but not less than 5 mm).
- - metal pipes (with a diameter of 20 and 25 mm, about 40 cm in length each).
Giving a six-sided shape
At this stage, it will be more convenient to work if the metal is heated. (I didn’t maintain a constant temperature and I didn’t manage to bend the whole part in one piece.) Clamp the strip in a vice at the level of the previously made indentation. Check whether the angle fits, try it on the appropriate nut. Repeat for each segment. As my strip has cooled, it has become more difficult to work with metal. This led to a fracture over the third leg. In my case, it went to my advantage, since when I began to bend the fourth segment, it turned out that its length was not enough and it was necessary to grind off some metal so that the nut would fit properly.(I think that adding a millimeter to each segment will help to avoid the lack of the length of the inner face of the key.) So I got a part consisting of two parts, each with three faces. (It is possible to work with such a machine easier than with a single piece curved into a ring, as I had planned to do initially.) Check that the workpiece is properly put on the nut. But not too tight. (If necessary, you can grind off a part of the inner surface of the faces)Now it remains to weld the part into one. (In my case, I used a 2.5 mm welding electrode) After that, you need to try on the nut again, and if everything is suitable, then you can fill the incisions with welding. (3.2 mm electrode). Again we try to put on the nut,because the high temperature during welding can deform the metal. (At this time I additionally tried on the workpiece to the six-sided protrusion on the filter ...) After that, you can clear out all the excess by making the part shape more smooth.Only after this step, the result of the work can be called a tool. I just welded the pipe on top of the received part (it turned out to be suitable for my single-purpose key). And then after trying the key on the lid E van filter, I welded to the pipe handle. (They are made of a pipe with a smaller diameter cut in half). I welded them at an indirect angle, so it will be easier for me to work. (If I had fixed the handles at 90 degrees, then, when rotated, I slammed my knuckles into the hood latch.) After grinding and rubbing with a brush, I applied black paint from a can on the key. Now everything is ready .

>After grinding, place the part on the sheet of metal from which the strip was made, and draw its outline on it. I preferred to carry the line along the inside parts, adding a couple of millimeters at the edges. But you probably can want to circle the part on the outside, on the contrary, removing an extra couple of millimeters. Then weld the received top part onto the previously manufactured part. (We use 2.5 mm and 3.2 mm electrodes) Check again whether everything fits.

ApplicationThis socket wrench is quite clearappointment. It’s a pleasure to change the oil filter with it. But I think that the way I made the tool can be applied to any other bolts and nuts that are in hard-to-reach places. The manufacturing method is quite simple . The work does not take much time (I made it in 3 hours), and the key is quite cheap, even if all the materials you buy in the store. I think that after this project, I will do more of such tools in the future. I hope you enjoyed it.
