Hey all, I just wanted to share my latest build experiences.
I had a twisted 30 gauge 9 wrap in my Kayfun 4 and it was great. came in at .13 ohms. Bit of a pain to wick, but not too bad. I used KGD for wicking, which I really don't like that stuff, I'm a Rayon guy. Some of you may know that I was thinking about trying Titanium grade one coils.
And I did. I did a 9 wrap spaced Ti coil, and the stuff is 0.5mm, which equates to about 24 gauge. The kayfun 4 had no trouble capturing the leads, which I was worried about, it's thick stuff. Being so thick, it's obviously very easy to work with, and is much more sturdy than nickel, but much less sturdy than kanthal. It's about in between. I was actually able to wick it with rayon, and kind of did the screw in method, which got the density about right. Usually I go more dense than I did, but beggars can't be choosers, my experience with rayon as a wicking material (especially in tanks) has ALWAYS been much better than with japanese cotton.
It's working really nicely, I have it set to 370F to compensate for it being titanium, and the build is .24 ohms. I wish I could set it to 365, because I'm having a difficult time deciding if I think it's at the burning mark or not, but it's probably just me. Rayon has a higher heat tolerance than regular cotton anyway. Running it at 24.8 watts and its a blast. Probably not going to mess with nickel anymore, I had high hopes for the Titanium and they seem to have been confirmed. Glad I gave it a try.
Edit: Yeah it's burning just a tad at 370, backed it off to 360 and it's fine. Probably need to adjust my wicking a bit. Being such a heavy gauge wire, it retains heat more, so when chain vaping, its going to want hit temp control a little easier. At least that's my theory
