GUYS! I just took this method a step further and resurrected COMPLETELY COLD ATTYS! Great find frostmonkey!!!! Instead of scraping the coils, when an atty is COLD just restretch where it broke apart, make sure it touches both sides of coil then mash it back down in there and VOILA!!!! A completely DEAD atty WORKING again! Take it a step further and be very careful w mesh/bridge and u can carefully replce everything but the fiberglass and have like new attys again!
That is excellent! I've tried this on 6 dead 510 attys but was only able to get one working and it hardly produces vapor, yet it seems all my dead attys failed somewhere in the wire leads or coil terminals.
It is interesting that without any soldering it's possible to restore a dead atty coil. Picture of how you did this would be amazing if you could

.
Any thoughts on WHY this would work?
This mod seems to work because the fiberglass wicking covering the atty's coil builds up with gunk and essentially becomes a part of the black slag buildup on top of the coil itself. After removing the wicking you end up pulling a lot of the gunk off the top of the coil therefore decreasing resistance.
Removing the bridge is simply a means to get to all of the wicking and coil easily, and maybe even give the coil a good scraping. Also, if an atty has a hard draw removing the bridge seems to improve airflow just a bit. Then again maybe it's just me.
