Coil raising itself

[patrao_n]

So lately my coils start to climb. I build it close to the deck. After a couple hours its raised to the point the whole coil is above the air hole. So I push it back down. And in a couple hours its raised again. I have checked and double checked my screws. They are tight. My wire isn't melted. The build is a .7 and I am using the new contacts. Anyone else experience this? Any ideas of why its happening? I assume its the heat making the legs curl. I just haven't seen this happen before. It had only happened since the new contacts were put in.

Yes I experienced that. It was when I didn't anneal the Kanthal before wrapping the coil. It would happen overnight.

I've since went back to annealing by unfurling about 5" from the spool of Kanthal, torching it, them attaching the free end to the coiling gizmo and winding the coil.

They haven't moved since.

Are you using super thin wire? Like 30G or 32G? If so, are you using high VG juice? The only thing that I could think of is that maybe the juice is pushing the coil up when you squonk, especially if you are using high gauge wire and exploding up through the squonk hole.

Edit: I assumed you knew how to build coils properly. Always anneal. If you already do, my comment may still hold some clout.

What attie are you using? Rm2?

 

[patrao_n]

Atty is rm2. Wire is 26 gauge kanthal a1. And I will go back to the way you are doing it super. Thanks for the info. I didn't even think of that. It just so happens that I also switched from annealing before to just firing the mod and pinching.

If you anneal, I am sure you have seen the wire change shape as it gets red hot. I think this happens to the coils once installed as well, flexing the legs and lifting the coil.

Also it can happen on nano coils, they like to move when they get hot. I always anneal my kanthal so I cannot say it have ever had that problem, I think zmauls is spot on.

 

[patrao_n]

Yeah my coils are wrapped with the inner diameter of .0625" using 26 gauge wire. I will be going back to annealing before wrapping.

Isn't the majority of Kanthal we use already annealed at the factory before we get our hands on it? All of my spools (Temco 24, 26, 28, 30) say "annealed" on their labels. Are they doing a cruddy job or does the annealing process lose it's effect over time?

 

[patrao_n]

I think its annealed, just not enough for our purpose.

Not annealed for a very very long time but never experience coil raising.

26g btw.
