Twisted coil jumping ohms

I'm a new coil builder. I do everything by hand, including twisting my wire.

Tonight I spent an hour trying different coils and configurations on my voopoo drag and peerless rda.

I built a 3mm id, 24ga ni80 coil with 6 wraps. First reading was 0.17ohms whilst pulsing and eliminating hotspots. Wicked it and it hit like a champ. 5 mins later it read at 0.27ohms and now it's on 0.3ohms and I can taste cotton.
Can anybody suggest why a coil will jump around like this? Keen to learn
Thanks in advance

May be contact screws not tight. Usually when my ohms jump I have a leg not tight enough

It's settled on 0.29ohms.
The one connection was loose.
Heats up evenly from the middle, but thinking of running a second coil next time

Bro you need to twist that wire way more until it's even. Try this... I twist by hand as well.. also n80 will jump and settle higher than when it was installed. That is normal. Do yourself a favor and twist the shit out of it.

I have started using kanthal again on twisted builds. I never do 2, I think 28g quad reigns supreme. Better taste

Do you twist all four strands at once or twice two sets then twist the sets? If you can understand my giberish

Dude it's not gibberish. Your curious and that's what got me into building. If you twist 2 sets then twist together tightly that is called hive, if your twist two sets then back twist that makes chain wire. To do quad twisted you have to twist all 4 wires at the same time together.

Here's a quad and two hive wire

No problem. You just need to figure out your sweet spot and that feeling when it's right about to head but before it bunched up

There really no wrong way to twist wire..... but yah more small wire is better than a single wire to get like power outputs.... experiment 4x twisted then try twisting pairs then doing a pair and aiding th 3rd and 4th with opposite direction of twist for each added strand... ect... steam-engine.org will even do calculations foe you. Just note error us greater for each strand of wire.

No, but there are better ways to go about it.
