Strange...Coils move - it's a fact

[super_X_drifter]

Just wanted to share that the TH on my vape was very harsh this morning.

Upon removing the top of the RBA I observed that the coil had risen a couple of mm!

Not sure how this phenomenon occurs but I checked another nearly identical setup and it had risen overnight like 3mm.

So I pushed em back down to about 1 mm above the deck and the TH is back to minimal, the way I like it.

So it's either:

1. My kids (they're all under 12) got into my gear and raised the coils.

2. My wife who knows nothing about vaping got into my gear and raised my coils.

3. Some freak broke in last night and raised my coils and didn't touch anything else.

4. It's a naturally occurring incident.

My money's on #4 so just wanted to throw it out there to watch your coils

Mine are both 29 ga Kanthal A1 micro coils with very short rolled cotton wicks like this:

#5 you squonk too hard, FORCING the coil up
#6 GHOSTS!!!!
#7 expansion and contraction from heat

#5 no because juice feed is in post eccentric to coil (but wick could possibly have "flotation" effect?)

I'm thinking #7

#8 It's the REO... It's ...... you selfishly took some time away from it!!!

#9 You have angered the mesh gods.

Don't worry.

Chinese company will build you atty with integrasted heat resistant webcam, so you can keep eye on coil all time.

Then you snap picture and call coil-cops ...

Interesting!

I have noticed this too SXD.
On of my kayfuns did this. I used twisted 30ga to wrap the coil and it is always lower to the deck than when I wick it.
Not a lot, but maybe moves from 1.5mm-2mm down to about 1 mm.
On some of my rdas, I have noticed it as well.
I'm not sure if it has anything to do with thinner gauge wire. Possibly the coil being under tension while attaching the post screws.
Not sure.
But there could be some memory left in the kanthal and it is returning to it's home position, if that makes any sense.
It's like cold setting steel. It'll hold it's shape, then return back over time. I deal with this in bikes all the time. Bicycles, that is.

Aren't #7 and #4 the same?

I built a side by side microcoil in my protank and vaped nicely on it for a few days with great results, woke up one morning and had the most unexpected nastiest metallic vape one could have. After my coughing and gagging spree I opened er up and found both coils were against each other like fighting for center spot..little DIY and seperated them, now I take smaller recon hits before I take a vape. Yes the coil does move around and I'm not going to take a ugly hit like that again.

I've also noticed this. I like my coil low as well. The twisted 28 I've been diggin seems to be the worst at raising itself.

The other issue is my screws backing out of my cyclone and giving me a mediocre vape. Grrrr didn't notice right away and thought I was having battery issues. I replaced the stock screws with Phillips head screws because I lose things like hex keys lol. Wondering if the hex screws do better at that job?

I don't know. I despise those hex screws . I replaced all mine with Phillips

The screws don't auto loosen as easy with 29 ga

my money is on the tension of the screws forcing down on the wire, thus kind of pushing the coil slightly upwards. whats you think?

That could be it too.

Have you ever noticed when you torch a length of wire to anneal it, sometimes it will curl a little? This is just residual stress in the grain structure relieving itself, so in way you could call it "memory". Did you torch the coil legs to anneal them? The coil wraps get annealed when you dry fire it for the first time, but the legs don't get hot enough (luckily, as we know this is bad). So the stress relief happens over an extended time period. I could see the coil raising itself again if you simply bend it back to where it should be because this adds more residual stress. I've also seen that you guys are winding your coils directly off the spool recently and using tension alone to keep the wraps tight and in place. Not sure if you are also taking an annealing step. I'm still winding coils by hand like a noob, but I always anneal the entire segment of wire and have never noticed a coil moving around after it has been mounted.

At any rate... interesting topic

10. You sucked on it too hard that first hit in the morning - thus raising the coil?

JK LOL

Long tome no see. Tried any AO (white wicks) on the REO yet?

 

[Rickajho]

OOOoooooOOooOOOoooOo... Call CoilBusters?

Just curious: For you guys who have this happening are you annealing the wire before you build? Or no?

 

[BobC]

The coil isn't moving, your eye is twiching

actually I have. for the most part though I haven't really vaped much ceramic but did try a piece of ao that gdeal had sent me some time back. I guess I had been vaping micros and hemp for quite a while the ceramic seemed a bit light on TH. the flavor, as you know is freaking awesome but just didn't have the kick. anyways I still have one genny still set up with a ceramic wick and vape it a little, but for the most part I vape my reo/ aqua/ kayfuns with hemp fibers.
