18650 soldering iron
daniel444:
soldering iron build
uses ngk glow plug , silicon nitride ceramic tip , 3mm tip , top of the line glow plug
25A momentary microswitch , beer keg stainless tube surround
fits a weller tip after being drilled out with 1/8 drill bit , then uses a small offcut of pyrolitic graphite thermal pad to hold it on by friction
switch needs to be held on about 1/3 of the time for lead solder
pictured is a spare glow plug and a Chinese nitride glow plug i bought , the Chinese version wont fit the weller tips at 4.4mm but is cheaper and more readily available
draws about 10 amps , im NOT using the high drain 18650s if i were it might be to powerful maybe
fmkit:
mine also looks crude, unlike original temp.is contrlled w/MT3608 DC step_up,as well 18650 is under-voltage protected.

That's insane, why have I never thought of using diesel glow plugs before, they'd be brilliant for all sorts of things

yes i might use it to vaporize some essential oils , with the solder tip removed of course , id like to do a torture test on the silicon nitride strength and inertness
