Step 1: Solder Iron Assembled

All three parts when assembled.

Put copper wire inside antena pipe with same diameter. I grinded it a little to be able to fit inside. At the other end put steel wire with same diameter.

Step 2: How to Use

Use it with candle.
Put the flame only to copper.
Clean copper part for best effect.
I use it for years, becouse of easy conceilability and travel sizes.
It works great, heats fast - in about 15 sec.
Its usable with other sources of flame like alcohol.
I have made upgrade to electric for stationary use - just one old fuse(ceramic) and heater wire (cantal) from old water heater. Only 24 volts, becouse of open wires.

    Years ago I had to make a solder repair and my soldering iron didn't work. I held a nail with a needle nosed pliers over a candle as an emergency soldering iron. I still can't get over how well it worked! From my own experience I can say this does work. Thanks for posting this for others who may need this info.
