Was vaping my IPV4 with the mutation X clone on it with the twisted 29 kanthal coil at 100 watts and the batteries died, so put in a fresh pair. To conserve battery life I decided to turn it down. At 80 watts still had great flavor and clouds, but at 60 watts the vape flavor became much sweeter. At 80 and 100 the vape was great but at 60 a real sweetness flavor came shinning thru on the vape. The slight muted dull taste of when the coils are about dry was more pronounced at 60 watts too. Learn something new every day!
I went with Ti because I have a Nickel Allergy. From what I've heard I could probably vape nickel but I decided it wasn't an experiment in the interests of science I wanted to do. The Ti seems nice. I got the Unkamen wire. I didn't anneal it or dry burn it. Well I heated it just a bit but not near glowing. I didn't want to mess with it at all unless I found it necessary in practice.

I did have a question, I did 6.5 wraps on a 3mm rod. This is on an STM RBA deck. The box is showing 0.42 ohms. When I run the numbers for Titanium 1 on Steam Engine for 0.42 ohms I get 9 wraps. I'm thinking maybe I have some resistance elsewhere in the system? But it seems to be working but then ignorance is bliss since I have nothing to compare it to. Vaping at 330F is a very mellow vape. As I cranked it up to 430 it got progressively hotter. At 430 it was basically a dry burn and I backed it off. The hit seems real smooth, I don't hear any rattlesnakes inside the mod. If I knew more about what I was doing I'm sure I could find something to complain about but I'm not smart enough for that yet :)

Oh yea, the mod weighs a couple of pounds, but I'll get used to it.

Difference in leg length

I allowed for 6mm of leg length. Would be tough to measure on the deck but that should be close enough not to throw it off much.
That might be too long for the STM....specially with a 3mm coil

Look at the bottom side of your coil, and make sure the leg isn't touching the first coil... This will alter your ohms...kept getting that problem my first week of building tc coils :p

Not exactly sure what you mean but if anything is touching it would be reducing resistance, not increasing it. I have too much resistance for the coils and leg.

I'm about 35% over (too much resistance). A 3mm 6 wrap coil would be about 82mm long. If I estimate 6mm on the legs but it's really 3mm, I'm only overetimating by 3/82 = 3% resistance. The legs can't throw it off by much. I have about 35% more resistance than I should for a 6 wrap coil (0.42R actual vs 0.3R expected

I always build spaced coils, and I have that problem with the leg touching the next wrap on just about every coil I build, and have to physically separate them with a needle. I did once try wrapping them on a screw, to get even spacing, but it's too tedious, I just eyeball it now.

Check the resistance from the positive post to the positive pin then the neg post to the base.

I just checked my subtank mini and got .09 ohms using a calibrated resistance meter.

That is just about my "surplus" resistance. I'll have to check that. Thanks for the reminder.

I love the machine screw method. I even leave it on the screw while attaching the legs... Back there screw out, bam! Perfect coils :p
