Simple third soldering arm

Today I will tell you about a wonderful idea how to make a third hand for soldering with your own hands. This device will greatly facilitate the soldering process. The soldering holder will ensure the fixation of objects when working on precise projects. This is the soldering of printed circuit boards, electronic circuits, and even jewelry. And just solder a couple of wires to some resistors, transistors, microcircuits, etc. much easier.

We will need:

  • A piece of laminate 200 * 160 mm.

  • Two metal plates 100 * 10 mm.

  • Two metal plates 50 * 20 mm.

  • Four corners.

  • Metal plate 50 * 50 mm.

  • Two crocodile clips.

  • Nine screws and nuts to them.

  • Copper wire.

Making a third hand for soldering

To start, I drilled three holes in a piece of laminate. One from the edge, another 120 mm from it, the third is just on the side.

We fasten the corners to metal plates, to those that are wider and shorter. I took the plates from an old children's metal constructor. If this is not, then it does not matter, just find any metal plates, and drill only the necessary holes in them.

We fasten long plates to short plates. I thought that they were too thin, so I screwed two plates, respectively, at once, in the end, I needed 4 pieces. So take the plates thicker so that under weight they do not bend. And we fasten the crocodiles to them, fasten them to those screws that are in the crocodiles.

Now, everything that we screwed together, we fasten to the laminate. You will need long screws, all screws, by the way, from one designer. The simplest option is ready, but we will not stop there.

Let's make a stand for a soldering iron. You will need a copper wire. We wind it on the marker, forming a spiral. The braid, of course, needs to be removed, if any. The spiral should be so high that the soldering iron tip is about 10 mm from the laminate. From the lower end of the wire we form the eyelet and fasten it to the laminate. That is why the third hole was drilled.

We also drill two more holes in the laminate and the metal plate. And fasten it. It will be convenient to use solder, rosin, flux, etc. on this plate.

You can also attach a magnifying glass, but I do not need it, and I do not want to overload the place. This can be done. The third soldering arm is already ready. I have been using it for over a year now and am happy with everything.
