I have been trying Ccell ceramic coils (all variants). While they are compatible with Aspire type tanks they just dont wick. Constant dry hits even at low power. Avoid like the plague, they are shit.........
So, in my search for a decent ceramic coil that is compatible with Aspire Atlantis type tanks I came across Freemax 20-160 watt coils which came with the Scilla tank and are very good, wick really well and last ages.
The Aspire Atlantis coils work fine in the Freemax Scilla tank, however the Freemax coils are not threaded on the top of the coil so Atlantis tanks are not held together.
This is remedied by getting an M11 x 0.5mm die and cutting your own threads.
A die like this can be procured from China on Ebay for ÂŁ2. You will need a handle for turning the die on the coil to create the threads and a vice to hold the coil still.
I wrapped the coil in cardboard and tightened the vice just enough to stop the coil turning with the die.
I did not monkey it right up and crush the coil like a fanny..........
I cut threads about three mm down the coil, just till it was about level with the "w" of the laser etched 160W on the coil.
Then I discovered the coil did not screw into the base because the band around the coil where the silicone seal sits is too wide to fit down the aperture on my Aspire Atlantis 2 base. I measured it with vernier callipers and it was 12mm, the stock Atlantis coils measured here were 11.8mm.
So simply remove the silicone seal, file away 0.1 mm all the way around and replace the seal.
Now Your fantastic Freemax 160w ceramic coils fit all your Atlantis compatible tanks.
Profit.
Win.
Nice.
