The heater cartridge

i made this post about the heater cartridge because i did not find much on the internet about making heating elements so here is what i did

i made this heater out of a tungsten wire that is about 40 cm long with about 5.5 resistance
i wind the wire to make as small as i can and put it in a heat insulator and i putted the insulated wire in a piece of  little metal tube got it from an old radio antenna

the pictures will describe better the making of the heater
