Good evening! I hope everyone had a great weekend and is settled into Monday;(
I have a few pages to catch up on so here I go!!

Nothing quite like a newly wicked coil. Yummy! Just did a Unicorn which has FANTASTIC flavor and a Dead Rabbit another with great flavor. Both are on Topside squonks.
Yeah mate I have done the experiment...I posted about it above. That's what set off this whole thing for me. I built two identical coils..one Ni 80 and the other Kanthal. To me they ramp up the same, but according to Steam Enjin the Kanthal is faster....fractionally.
Heat capacity as I understand it, is how the ramp up speed of a wire is measured.
Ni 80 takes more wraps to get the same resistance as Kanthal...but even if I project Ni80 to the same amount of wraps as Kanthal (using SE), the Kanthal is still faster on ramp up....fractionally.
This is a screen shot from Steam Enjin about heat capacity
This is further down. I'm not to flash in the English department...you will make more from it..?

Seriously??!! I had to go and check as I didn't remember entering any comps
But I've won an innokin Kroma 217 kit!! I am so stoked

Congratulations!
I got some mail today. More 21700 batteries and the new Drag kits and the Centaurus Quest for reviews.
Yeah I read that. Again, not according to Steam Enjin. Check it out. Nichrome 80 has a higher heat capacity than Kanthal.
That actually makes sense to me. If Kanthal has a higher resistance than Ni 80 it has more "electric" friction, thus it'll heat faster.
I know it's the general consensus, and always been said that Ni 80 is faster than Kanthal, but Steam Enjin's figures shows that it's not.
Riddle...isn't it
My understanding is that you are both right.
Using a 5 wrap 2.5mm id 24g coil:
Ni80:
0.321 Ω
Heat flux per Watt 10.31 mW/mm²
Heat capacity 46.01 mJ/K
Mass 102.93 mg
Density 8.31 g/ccm
Ka1:
0.427 Ω
Heat flux per Watt 10.31 mW/mm²
Heat capacity 40.45 mJ/K
Mass 87.94 mg
Density 7.10 g/ccm
On Steam Engine, kanthal does have a slightly lower heat capacity of compared to an identical ni80 coil. That tells me the kanthal will be cooler to vape than the ni80. But I don't know if that correlates to ramp up.
But like @Pigs I've experienced a huge difference in ramp time between ni80 and other wires. My guess is the differences in Density and Mass are also playing a part - when we're talking about ramp up.
To see a difference @Fredman1 you may need to go for some longer identical coils. Completely forget about having the same resistance.
I'd use two coils with say 8 wraps each, so that there's a bit more of a delay for them to ramp up.
Interesting stuff Fred
.I'd hoped that Ange would chip in here - she understands the scientific side a lot better than me. The idea of using larger massed coils (more wraps) for a new experiment seems a good one.
I'm thinking I might send an email to Steam Engine and see if they can explain the correlation between heat capacity and ramp-up in layman's terms. Will post something if they get back to me.
I knew you'll like it Charlieman. It's one hellova tank...for sureHitting the hay here.
@Fredman1 Built the Kumo and it's a fantastic RTA. I'll post pics and review in the morning
Can't wait to try the Cabeo.

I'll do that. That would give a much better indication.
Ah..Congratulations on your win Ange
That's would be interesting to hear their response mate.Interesting stuff Fred

Good morning shinies
Here's the "finally built" Kumo sitting on a Mixx.... fantastic RTA.
Similar to the Brunhilde in that it is basically and RDA sitting on top of a tank. But the wicking system is truly innovative. It has a disc on the bottom of the 'chimney' which sits just shy of the bottom of the tank. The liquid is transported up and onto the cotton. So simple but soo efficient...you'll like this one T and it looks so much better than the Brunhilde....a real winner and so well machined. Aspire and Steampipes have knocked it out of the park with this one. So many spares and accessories too.
Have a good day everyone

Glad you like it mate. This is the wicking system of the future...i'm sure.Good morning shinies

Next challenge for the designers will be to make a bottom airflow with this wicking system
Where do you like the airflow?
I'm like it with 3 holes...but only 3/4s open

I need to have it wide open and then it's perfect!!Glad you like it mate. This is the wicking system of the future...i'm sure.

I had a little bit of an issue while wicking. I deliberately wicked it quite loosely as I've had some issues with dry hits on the Brunhilde. I had the same at first with the Kumo until I really made sure the wick was 'stuffed' down on the deck. Now it's wicking really well but the airflow is a tad tighter. I've tried clearing the wick around the coil but no dice....any tips??
Hi T, I have not used Kanthal in a long time but only SS. I might just try some Ni80. It is certainly easier to find than SS.
Its all those beautiful pics! The Gods are watching! They told Innokin.Seriously??!! I had to go and check as I didn't remember entering any comps
But I've won an Innokin Kroma 217 kit!! I am so stoked
Morning shinies
That is so stunning I can't wait to see your thoughts and review on the BF
After a crazy day at work it was nice to come home to something shiny.
That is so stunning
I can't wait to see your thoughts and review on the BF
The only thing you can do is to make sure the legs are well spread so there's no obstruction for the air to flow.
Yeah I also cut a bit on the long side... so the cotton lays well on the deck. I haven't yet had a hint of a dry hit though.
I've just received an SMS from Aus. Post and my Kool Kumo is on the delivery van and it's Komin' today
Now my Brunhilde's can see what all the fuss is about
