In this video I restored this old 'Gustav Barthel 300' Blowtorch. After purchasing the first test showed, that this old beauty still works a little bit. But the condition was pretty bad, so its time for a restoration.
I started with disassembling the whole Blowtorch. The tank was cleaned with paint stripper, and sandblasted afterwards. unfortunately i had to remove the old sticker as well. But i spray painted a new sticker with templates from my plotter. The whole paintjob was sealed in 2K clear coat.
After that the tank was done, i restored the brass parts. They were sandblasted with glass beads, after that i wirebrushed them with a brass wirebrush.
The last part was the type label. I removed the old paint, spraypainted the whole label in 2K black matte and engraved the original lettering with my laser.
The final test shows that this beast works perfectly fine now!

What is the small part in the nozzle for?
The small part AND the lever are a cleaning unit. At the tip of the small nozzle there was a little steel brush once. When hitting the lever, the brush cleans the nozzle. Unfortunately i couldnt remake this part.

How does this blowtorch work?
You start by hitting the pump for around 5-6 times. The pressure presses the gasoline at the top of the blowtorch. When preheating (what I did with a second Blowtorch), the gasoline transforms into gas. With the capillary effect new gasoline will be 'sucked' into the nozzles.
Without preheating things could end pretty bad, since the gasoline is still a liquid. it would splash burning gasoline around.
