    Default repair your 901 atomizer

    after about 2 weeks my first atomiser broke. I had a spare but i wanted to find a way too fix it just in case one breaks when i dont have a spare

    first insert a small screwdriver into the hole in the center of the brass connector and gently rotate/pry the center out breaking the exposed solder joint

    then insert a small flat machine screw into the new larger opining and press out the atomiser coil assembly the second wire should also break at the brass connector solder joint

    once the assembly is completely removed insert the machine screw in the other direction and place in a vice with just the steel lip on one side and the screw on the other tighten the vice to remove the threaded part of the brass connector

    to disassemble the coil i first pried up on the metal bridge covering the coil then wiggled on the mesh/ceramic until i could get it out but now that i have seen it apart you should be able to first remove the plastic cover or just widen the hole on the back with a drill bit and push the hole thing out hopefully keeping the mesh intact

    to repair the coil i used some thin stiff but ply-able wire to grip the broken end (copper is what i had but don't use copper it puts off fumes when it heats up)then its just a matter of re-soldering the connections and putting it all back together now i just have to find a good source for nichrome i tried some from a light bulb but it was too thin , glowplugs are too short and a fishtank heater was too fat

    i pictures and a vid but i haven't made 15 posts yet

    Maddog--if you think it is rough and takes a lot of patience, then I now really want to see what Vnshng is up to here. I can not see a 901 atomzer stripped down like that and put back together to be viable--but lets wait for his video--who knows--maybe the Holy Grail??????---Sun

    You should be able to get nichrome wire at the hobby shop. Its used to make hot wire cutters for styrophome model airplane wings and such, comes in 4 foot rolls.

    Been working with this stuff for the last 3-4 days - Unfortunately the resistance is not high enough at workable lengths - Still looking

    Good to know, Madog. I wonder how hard it will be to get the same stuff they use in the glowplugs. Someone has to make it. And if the make that, you should be able to get whatever resistance you need.
