ill try explaining:
rebuilding a bulbstyle atomizer from ft:
basically one just pulls out the center pin on the bottom that makes the connection with the battery. after removing the rubber ring one can pull out the coil from the top.
there will be 3 holes, the middle one for air and the two on the sides for the wires. one of them has a tiny tube in it to avoid short cutting. this little tube is probably the reason why some wires are suitable and some are not (diameter that can go through that tubing, i have only the standard wire from fasttech).
the hard part is to get the wire of the fresh coild into those tiny holes again, but with some skill it can be done without too much hassle.
steps:
1. remove center pin and rubber ring
2. pull out coil
3. insert wires from new coil into holes
4. fit in rubber ring, insulated wire goes through the rubber ring, the other one not.
5. put in pin and cut wires
done
if wished i can try making pics, but i doubt my cam will be able to provide accurate resolution
