Why settle for an approximation when you can have a real soldering gun?! Bring this little baby to bear on your next PCB. Point, pull, and let the heater rip.
It's not so far fetched: A steady hand, a careful aim, an unsafe quantities of lead...soldering and firing a gun have an awful lot in common. Making your own is easy, all you need is an air pistol and a hand-held, battery powered soldering iron and you can make your own soldering gun.

Signing UpStep 1: Disassemble soldering gun
I used a small Phillips screwdriver to open the plastic housing of the soldering iron and pry it apart. The circuit inside has a 51Ω resister, one small white LED and a socket for the heating element.
After sketching the circuit onto paper I desoldered the components and set them aside.

Awesome!

Cool Instructable!
As for the soldering iron tip: Nope, I got the idea after seeing the battery powered soldering iron when I was in Radio Shack. I actually only found out while writing this Instructable that you can buy just the soldering tip through RS's website.
Just a crazy coincidence!
I think the battery should connect *directly* to the solder tip, and the 51 ohm resistor is to limit current into the LEDs.
As it stands, the iron tip will get only about 0.1 amps of current, at virtually zero volts. Result? Virtually zero heating effect, with all the energy wasted in the resistor.
Comments, please.
I took great care to keep the same wiring from the original soldering iron with this build, with the exception of adding another LED to the mix. I have updated Step 3 to reflect a new wiring schematic and a new picture of the original wiring from the soldering iron I used.
the battery in schematic and LED orientation don't agree either (long line on battery is positive and it should go towards 'trailing side' of the LEDs arrow. short line on battery symbol is negative and should go towards "line" on LED symbol).
btw nice instructable and cute video clip. i like the "pew pew" firing sound effect :-)
and i think you should use rechargables and make a few spare magazines! :-D
love the idea though.
