The most important issue for lovers of hiking, survival and outdoor activities in general is to stay warm at night and in the cold season. Fans of going out of the house into nature are not at all stopped by the most favorable weather conditions. However, so that the rest does not turn into a truly deadly test, it is necessary to take care of the methods of warming up in advance. This is especially true for a cold winter, during which even a fleeting removal of gloves or mittens to perform certain actions threatens to completely lose a comfortable body temperature.

The way out of a difficult situation may well be a pocket heater, which anyone can make with their own hands from simple components. This device is easy to use and helps warm hands for later cultivation of a full-fledged fire. In some cases, this not only increases the comfort of rest, but even saves lives.

Materials and tools needed

To make a pocket warmer, you will need:

  1. Metal pipe. You need a piece about 100mm long and 25mm in diameter. The wall of the pipe should not exceed one millimeter.
  2. Plumbing lock nut 15 mm.
  3. 15 mm plumbing plug, equipped with an external thread.
  4. Broken headphone speaker, which has a protective grille. It is better to choose an element based on the diameter of the pipe used.
  5. Pliers.
  6. File.
  7. Drill with a drill of about 2 mm.
  8. Soldering iron with tin solder and flux.
  9. Marker to mark.
  10. Little hammer.
  11. Solvent.
  12. Cotton wool.

How to DIY

The manufacture of a pocket warmer begins with the preparation of the body of the future product. It is necessary to take a pipe of a suitable diameter and cut about 100 mm from it. Then the edges of the cut are processed with a file and sandpaper. It is necessary to remove all burrs to make the product as safe and convenient as possible.

Next, a 15 mm lock nut is installed on one end of the tube, which will serve as the internal thread.

The edges of the nut are ground at a slight angle, after which the ground side is placed inside the pipe.

The element is fixed with a hammer.

The second end of the pipe is closed by a grille previously removed from the old speaker. The closer the elements are in diameter, the more convenient it will be to assemble the structure.

If you can’t find an appropriately sized enclosure, you can use a thin, pre-cut sheet of metal. It is necessary to drill as many holes in it as possible, forming a kind of lattice.

The elements are soldered together with a soldering iron. During the work standard tin solder and acid solvent providing high adhesion are used. The remaining tin is removed with a file, and the solvent is removed with a cotton swab.

Drill a few holes in the plumbing plug that will provide good traction. The more holes you have, the better. Places for drilling can be pre-marked with a marker. Processing is carried out with a drill with a 2.5 mm drill bit.

After that, the pocket oven can be considered complete. To work, it needs fuel, which can be birch chaga.

Ordinary barbecue charcoal, medical cotton, a roll of cotton cloth, and in general any material capable of smoldering for a long time are also suitable. The fuel is crushed and placed inside the heater. All that remains is to open the cork, set the contents on fire and close it.

Such a heater easily ignites from a single spark, so there should be no operational problems. During operation, white smoke comes out of the tube, so it is best to always use the system outdoors.
