After retrofitting a Nautilus coil or two yesterday I decided today I'd aim my sights at a even harder challenge - retrofit my Aspire Maxi and T1 coils with temperature control.
Taking them apart was easy enough, I could see why I stopped using them - both had burnt cotton and gunk on the coils, one looked almost new (I had soaked/cleaned it so the coil looked ok but the cotton was still burnt).
With even less room than the Nautilus I figured even 32awg Ni200 was not small enough so I got out the 32AWG Ti and assessed the situation. The coil sits in a sort of u-shaped hunk of metal with cotton wrapped around the coil filling the gap between the coil and the metal (heat spreader?) and the outside is wrapped with a very thin wrap of cotton (looks like a tissue or paper towel).
After getting a bunch of wraps on a 2mm mandrel, I carefully slid the mandrel with coil inside a chunk of 3.5mm Silica rope. (I figured replacing cotton on this thing would be a PITA and likely would never happen).
However with TC and 2000F Silica in contact with the coil, I think outside the coil itself getting gunked up this wick will only need a simple rinsing - not replacing.
The rope with mandrel and coil inside was not large enough to fill the inside space of the 'u' shaped hunk of metal so I wrapped the silica with a bit of cotton to fill in the gap.
Mounted the Ti coil came out to 0.92 ohms. Here it is mounted on my SXminiM. I've since cranked the temp up to 430F. This was one of two tanks that came with my starter kit.
So if anyone ever asks the question - YES you can do temperature controlled toodle puffing with Aspire Maxi and K1 tanks however you'll have to rebuild the atomizers for TC yourself.
(the seemingly constant eating/clogging/burning of atomizers is what pushed me away from these and Nautilus tanks towards RTA's and higher powered rigs in the 1st place)
