I havent tried to rebuild these dual coils yet but i have just cracked one open to see how
they work ..you seem to make one coil up .. then put a tiny bit of wick on top of that .. then put
your next coil on top of that and thread it thru the first wick .. if you havent rebuilt one of these
before i would suggest try building a regular single coil first... single coils are not that difficult to make at
all once you have had a few goes ! ive been lucky and havent had any shorts as yet ... you just need to make sure you
have one end of the wire on the outside of the rubber gromet and the other end of the wire straight through in and just make sure
your coil isnt touching any of the metal edges
