Hi guys.
I needed a micropencil soldering iron to reach some tight place.I decided to make one fast.I looked around found this which wold do the trick

a glow plug from diesel engine and i think its from citroen or peugeot.
I took some copper wire and wrap it on tip and connected it to bench psu 12V 5A over a relay and a micro switch.

It worked amazingly well, it heats up in 3-4 sek and it's ready for solder melting .I made my job done so at the end i make a wooden handle

sorry for bad english.
