I have decided finally that I like the Crazy Wire better. Now I'm thinking SS. I like the way the CW is a little higher resistance and just seems to work better for me.

Possibly it adds some resistance. IDK don't think it changes the TCR value though. Wire is wire.There's an old saying that if you can't tell it doesn't matter lol. From a heating standpoint, it would be edge of coil. From a how does steam engine work and do its calculations based on entered leg length standpoint, I don't know either.
SE assumes the wire is straight once it exits the center of the coil if I remember right. Makes sense too because the wire length formula would change from a perimeter calculation for wire length to linear length at the center. My calcs in SE always come out closer to actual when I measure the leg length from the center of the coil to the post screws.

i've been using .4 mm ti coils for the last 2 weeks or so. when i clean them by pulsing at ~10 W to a faint red, does anyone have an estimate what temp i'm heating the wire at? i'm just curious, no real reason other than maybe the effects on the gunk.
I have no idea what temp I'm dryburning at but for reference I'm pulsing for a full 10sec at 7w with 24g 2.78mm 6wrap Ti coil. 21 dryburns so far and the coil still looks and vapes great. The end turns of the coil get hot but don't turn red. The gunk turns to ash at 7w. I just give the coil a quick brushing with an old toothbrush and rinse.

i'm glad to hear the coils last so long. i have 2 in rotation, 6 and 7 wraps of .4 mm @ 3.1mm id. i was just curious from a physics/chem viewpoint on the temps.
Maybe @druckle will chime in. He's our resident metallurgist.
In the mean time my advice is to dryburn at the lowest power required to turn the gunk to ash. If I recall correctly @druckle said 1100°f is the temp Ti begins to develop dioxides and recommended not going above 800°f if possible.

How is it working out and which one did you get?
Thanks!
Their stuff seems fine... according to stream Calc, everything turned out as expected for me with it.
I've been using 24 gauge titanium wire for almost a month and have to say it is the best vape I've had so far. I'm doing 6 wrap of cleaned ti wire spaced around a 3mm screw and has just been incredible! I'm using my trusty kayfun lite . I even went back to my normal clapton kanthal and just doesn't compare!
I'm still on my first ever 24 Awg titanium coil... Like two / three month old now.
Our Hungarian friend's dry burn method is absolutely perfect for me.
I change my rayon wick once a month, dry burn and ready for another month... Vaping is just hassle free and awesome

Program a curve with a TCR of 0.007 and set the temperature to 300C and assign it to an unused profile on the dna 200.
Max temperature will be limited to 600C (real) and you can pulse whatever you want and the coil will never be overheated to the point of forming TiO2... Gunk will fall off just like with a normal dry burn.
Best idea since sliced bread.
EDIT: Corrected mistyped TCR value

Are you SURE it's "0.070"? I'm just getting into this again, as I now own a LavaBox DNA200, but I kept two notes on this technique from back in this thread, and both say: "0.007". Here is one paste, as you can see there is an EXTRA ZERO -"0". Just want to confirm, for me and anyone else just joining this thread. Typo perhaps?

"Actually it is possible with the accuracy of our mods.
Specific TCR can be calculated to shift the real temperature for dry burning. I have made it for Ti: if you set the TCR to 0.00725 and the temp to 570°F the coil will be about 1100°F I am sure that it's not perfect, the TC algorythm has been developed for wet coils, but it is good enough to have a rough limit."
