INSANELY HOT DIY Hot Air Soldering iron @ 15 Volts DC and 3.5 amps...PART II

Step 24 I got just over 360 degrees celcuis, but missed the capture...damned slow camera

Wickedly hot air ...and concentrated ....and controlled.... everything I had ever wanted during this past week of making this beast. Changing nozzles changes the width of the heated air being forced out...changing the voltage in conjunction with the air flow changes the temperature. That is, increasing the airflow allows me to reach even more insane hotness by increasing the voltage. The element was glowing red at this point and I still could place my fingers onto the barrel without hurting them...If I laid my fingers there for too long it got a bit hot though.
