Macro coils can they touch without a short

[morningdew]

So, I build both micro and macro coils.

Micros of course all coils compressed and touching.

With macros, I just wrap a micro coil on the coilmaster and then spread it as even as I can by hand.

With my macros, the odd coil does touch another.

Of course I make sure that the coils do not touch any of the rda cap, posts, inside well etc.

Don't appear to have any issue with the macros shorting, but have just read a fair amount saying coils must not touch, have I been missing something here.

For info. I only use regulated mods with short circuit protection etc.

nvm...nevermind?

as in nevermind you stopped posting or i ought to not mind i.e. not a problem with coils touching?

I posted something, but figured it was not what you are looking for, so i edited it.

I'm confused by your question.
If you are using kanthal or SS (in power mode rather than TC) your coils irrespective of internal diameter can be either touching or spaced, it's a matter of preference.
A touching coil will quickly form a layer of oxide that insulates each wrap from the next preventing a short. Gently pulse heating it and tapping or strumming the coil will expedite this process.

Micro vs macro is about coil id. Contact vs spaced is OK regardless of coil id

Ok let's see if I can get the question across better. Forget micro and macro - Seems to be confusing the issue as different folk use it to mean different things.

If I build a spaced cool, say 7 wraps, if a few of the wraps touch one of the other wraps, will this cause a short?

Reading around the web, there's a lot of mention that wraps mustn't a. Overlap and b. Touch another wrap.

I have been building with some wraps touching and others spaced, best I can do when spacing the coil that comes off the Coilmaster.

My builds don't seem to be shorting, however what I have read suggests they ought to, hence I am concerned that I may be missing something!

Thanks I think you have actually answered the question.

For info. My understanding was

Micro is a touching coil
Macro is a spaced coil

Coil id is simply coil inner diameter, micro and macro have nothing to do with the id of a coil.

I don't think that your understanding jibes with terminology used by others, and I think that you're beginning to see that. Here's a thread that you might want to review (with contributions from the person who "invented" the micro coil): Nano coil vs Micro coil, is there a standard definition?

what you read about wraps must not touch was probably refering to using nickel or titanium

It used to be "common knowledge" that wraps shouldn't touch, but that was before people started wrapping contact coils and even tensioned contact coils(where tension is applied to bring them even more in contact). So, touching is okay. It's probably best not to have overlapping coils, but not really an issue with shorting, more an issue with a hot spot from the heat of two wraps intersecting, but that's just a guess from me.

Macro micro and nano are/were terms used to roughly group coils (spaced or contact) of a given internal diameter. Once you get a feel for what size works for you they become irrelevant, so don't put too much value on them.
Me, 2.5mm is my nominal size. I occasionally use 2mm for small RTAs and some times 3 or 3.5mm for big nasty cloud blasting builds.

As stated, ID is, as most everything else, personal preference... A lower ID will heat up faster, so produce more vapor in shorter amount of time because of lesser amount of juice/wick cooling the wraps down. The benefit of higher ID is to have more cotton/juice to hold up better as resovoir for hotter builds as the capillary action might not happen fast enough to avoid drying out and burning the wick... I really like 2mm, for the responsiveness, but its pushing it for my hot builds, so I generally use 2.5mm...

Originally, the inventor of micro-coils defined it's spec to be a contact-coil of 1.4 to 1.6mm and so everything above could be considered macro or regular/normal coil, but in more general broad terms and also mostly used, micro-coils is also considered as 2mm ID and sometimes 2.5mm, and macro-coils usually are 3mm and above, but it depends who you ask

This is the reason, me and many others, just prefer stating contact-coils(or spaced-coils) of whatever ID used, instead of micro/macro-coils...

Got it. Thank you people.

Back to my 3mm id, spaced and contact coils

Being a net vapour the larger Id would seem to help prevent gunking, as does spacing the coil.

Coils can touch and they can also have shorts if they do touch. Dry fire them when they are pressed together, while they are heated up, rub something on top of them, usually takes care of shorts. Just make sure you are not rubbing metal on them while button is pressed.
