I have tried numerous ways to rebuild the dual coils for my pt3. The best way I have found is to use cotton ball for the wick and make the coils a bigger diameter about the size of a toothpick. The trick is to get the proper amount of wick in each coil. It seems like it wont be enough to keep from flooding with such a small amount of cotton, but it doesnt unless you use to little. I use 32awg Kanthal and wrap 8-10 times, I actually started using a toothpick after I got tired of burnt wicks from the micro design. I get around 2.2ohms with this way. I also do not use the dividing flavor wick between the coils. This makes it harder to rebuild yet! But once the 2 coils are in the body, you can adjust them to be spaced out correctly and away from the other metal surfaces after the insulator is in. Then slap some wick in it and prime and go. Only need 2 pieces of wick, no flavor on top and no divider. 2 coils and 2 wicks has stopped me from throwing this thing in the garbage!
Also, I get good flavor and lots of vapor production now, that I haven't gotten since the 1 original coil that came with my protank3 burnt up in 2 days... The second original was even crap! Never bought any aftermarket coils either. With the price and the short life span of these, I would've bought a new tank if rebuilding wasn't an option.
