Question about rebuilding coil

[onezerosix]

So, my coil was not doing anything so I took it apart. From the looks of it, if I have the right type of wire, I can rebuild this. So, my question to the wise ones of the forum. What's the pros & cons of rebuilding?

Cheap cheap cheap
Pretty easy, too. I just started vaping (this is my forest post, actually) and started rebuilding almost at the same time.
Pretty fun if you like to tinker. More variance in your vapor output from what I understand

I won't pretend to be entirely too knowledgeable, though. I'm sure the more experienced users can enlighten you about the real pros and cons

Very cheap and fun!

There are good tutorials on you tube showing how to rebuild protank heads. I recommend a micro coil with 28 gauge Kanthal and cotton wick. That way you can just replace the wick when the flavor drops off without changing the coil again. It's cheap and fun, just keep the resistance up over 1 ohm and you'll be fine.

A lot cheaper!!! Why spend $8 or $9 on a 5 pack of coils when you can get a bunch of cheap cotton balls and 100 ft of kanthal for $8 that should last.....forever?

I use 30g. How does gauging effect tire outcome? I just had a friend teach me and left me with some starter stuff

Good question. The resistance per foot is lower with larger wire, and I've heard that the vapor production is higher with larger wire as well (maybe only because of the lower resistance?). I like 28 because it make a good strong micro coil, but I imagine 30 is plenty strong enough.

For a protank build, 30 might be a little better because the space is small and if you want to get a 2 ohm coil you won't need as many wraps. I've only tried it with 28, I think my coil came out to 1.4 ohms.

~8 wraps with 30 micro coil and I'm at 1.8 ohms

i do 4 over 3 under with 32g on 2mm wick and get 1.7ohm each time heck did 8 coils yesterday all hit 1.6 to 1.7 and vapes like a dream maybe its because the coils are nicely spaced and not crowded on the wick.

Why rebuild?

As other have said, its far cheaper than buying really crappy, useless, worthless, stock coils.

Also, a rebuilt is not crappy, useless or worthless .

Rebuilt coils have far superior flavor, much cleaner vapor and resistance for resistance they produce much more vapor as well.

My favored build:
1/16th inch internal diameter, on either a precision screwdriver or drill bit.
30 gauge wire
8 wrap contact coil (aka micro coil)
1 strand of peaches n cream ekru cotton yarn through the center

This build comes out to 1.8 ohms, and never leaks.

PS. With the frequency that I post that build setup.. I really need to write a guide/blog post about them.

Over and under? You lost me.

 

[Nataani]

if you count the number of 'lines'.

The top side of the coil will have one more line than the bottom, where the leads exit from.

I must be sleepy, because even that took a minute to understand. Wow

i may have to head to local vape shop & if they carry rebuild material. i love DIY stuff

Honestly, from what I understand kanthal wire is best bought online.

I use organic cotton balls from CVS, if you have one of those near

Which resistance & gauge be good to go for?

Hey Rob, what wick do you use and who do you buy it from? Thanks!

30ga works very well for builds on the PT heads. Do not buy wire from your B&M, unless you like to get pooched! My local is charging $1.79 per foot! Here is a link...7 bucks with free shipping. Wind 8 wraps on a 1/16 bit touching, and stuff with cotton. Good luck!

28 gauge is the best in general. Works well for protank heads and advanced rebuildables like Kayfuns or RDA's.

I always shoot for a 1.8ohm resistance. Any mod works fine there, and it is easy to replicate. 10/11 wraps on 5/64ths ID.

Actually IMO and this is just IMO, 30 gauge is a better all-rounder than 28.

Two major reasons for that...
1) I have compared the common 10/9 wrap of 28 to the 8/7 wrap of 30 on protanks. The 30 gauge produces much better flavor, with the same amount of vapor.
2) Triple twisted 28 gauge is a pain to work with, you will have issues getting it through the posts of some RDAs. Triple twisted 30 gauge on the other hand is just small enough to work with, allowing you the flexibility to build some very nice sub ohm coils for RDAs.
