I have an aspire atlantis and have some Japanese cotton and 26 guage kenthal wire. I want to try rebuilding the coil and it does not seem hard, 5/32 drill bit, etc but how do you keep the coil from burning the rubber grommet? I think the stock coil has some resistance wire soldered on to the ends. I've seen people rebuild on Youtube but they never mention anything about the whole coil turning red.
