I've been in the same camp as you Mawsley when it comes to TC vaping. I've played about with it on and off but never been taken with it so my daily vapes have always been good old Kanthol. I got some Stealthvape Niffy too to try and get a good hold on it at long last, just don't like Ni200 and don't fancy Ti at all, imagine doing what you've just done with Ti
, no thanks.
Anyway I ended up putting a dual build (something I'd never have managed with Ni200) in a Billow V2, 8 wraps around 2.5mm of 0.28 twisted coming in a steady 0.09ohm at room temperature. I've run four tanks through it now running it at 30W, same as I do with my Kanthol build in my other one. I tried to get the coils around the same size and mass as my Kanthol build too, not far off I don't think but I couldn't manage a clapton, maybe try a Kanthol claptoned Niffy core next time. It was a bit of a bugger setting the coils from the start, hot spots took a bit of getting out, tried not to dry burn them too much but it did take a bit to settle them.
To start off I put it on my fancy pants VTbox200 thinking I'd set all the right TCR's downloaded from Steamengine and it'd be all nice and easy. It was easy downloading it and setting up a profile for it and it did work great once I'd turned the preheat power and punch away down. Going by feel and watching it on the device monitor it was coming right up to power and temperature, the vapour and flavour was all there, nice and consistant, and I'm thinking wow this is it! nailed it!!! Only it didn't last for long, randomly it would just think it was way hotter than it was and back right off, then it would be fine again for another few toots. Given what happened next I'm thinking this must be something to do with the 510 on the VTbox, how are you getting on with yours in TC mode
Tubbyengineer?
Back to Steamengine I had a look at the Ni200 equivalent temps, let everything settle at room temp again and put it on my Tan plus DNA40 set at 210C, some might think it's a bit high but it should be just under cotton charring point, it just worked consistently
Today was the first time I'd felt confident enough with a TC set up to take it to work with me, again, no problems all day. Getting home tonight with a nearly empty tank (the fourth through this set up) I thought I'd give it a real test and vape it as dry as dry can be. I just kept on vaping it far beyond when I'd normally have filled it up, the vapour and flavour started backing off but still I went on until it pretty much gave me no vapour at all, but just as important no dry hits either,,,, this is the result.
After this pic I primed the wicks up again, filled the tank and it's vaping away again no harm done.
What are my thoughts on it??? Apart from the last bit which you'd never do with a Kanthol build it did nothing for me that I couldn't do with Kanthol with a lot less effort. The flavour is the best I've had from a TC build but still not quite what I can get from Kanthol. It has given me that little bit of hope for TC though, I'll continue to play around with it, maybe a dripper next now I know I can get a decent dual coil, maybe some hybrid coils.
