Soldering Iron DIY! How to make a soldering iron at home?! Amazing Project!

Hi guys! Today we will make a real soldering at home!
We need:
wooden blank,
wires,
nichrome wire (0.17 mm),
fiberglass insulation for wires,
solid copper wire,
gypsum plaster,
and so on.
This soldering iron is very compact, works from low voltage (12 V) and is quite powerful (12 W), which contributes to fast heating and comfortable, and safe operation with various radio and electrical components. Such a soldering iron can work from the batteries.
