**Project:** Restoration of a vintage German pocket flamethrower (gasoline burner)
**Summary:**
* The device was disassembled, revealing carbon deposits, rust, and worn-out parts.
* Various cleaning methods were used:
+ A commercial cleaner for non-ferrous parts (effective with minimal scratching)
+ Chemical paint removal for the iron tank (successful with subsequent rust removal using emery cloth)
+ Special coating for metal protection on the iron part
* After thorough cleaning and restoration, all parts were reassembled.
* The flamethrower was successfully tested, producing a powerful, high-temperature blue flame that works in any position, outperforming a standard gas burner.
Here are the extracted key facts, each numbered and in short sentences, excluding opinions:
**Device Information**
1. The device is an old German gasoline burner, also described as a pocket flamethrower.
2. It is compact in size.
**Initial Condition and Restoration Process**
3. The gasoline container was in poor condition with cracked paint.
4. The container needed to be unscrewed from the front of the burner for paint removal.
5. A vice was used to hold the front part for unscrewing.
6. Cotton laces were found inside, possibly serving as a filter for gasoline flow.
7. The piston of the pump is made of leather with a special lubricant.
8. A rubber gasket was found in place on the tank cover.
**Cleaning and Painting Process**
9. A mountain fireplace cleaner was used to remove carbon deposits from parts.
10. An emery cloth paper was used to remove rust from the iron tank.
11. A chemical paint remover (gel) was applied to remove the old paint coating from the tank.
12. The tank was painted with a newly acquired paint, which matches the original closely.
13. A special composition for coating real weapons was applied to the iron part for protection.
**Assembly and Testing**
14. After cleaning and painting, all parts were reassembled.
15. Purified gasoline was used for testing to avoid potential hazards.
16. A piston was used to pump up pressure inside the tank before ignition testing.
17. A bath of alcohol was set on fire to heat up the burner nozzle for faster evaporation.
18. The device was successfully ignited and produced a high-temperature, bright blue flame.
**Performance Observations**
19. The burner worked in any position.
20. It heated a thick wire to almost a white glow.
21. A brass tube melted in seconds when exposed to the flame, indicating high power.
