RE: How many wraps
~8 wraps round a 3mm will give you 1.8 in your 28g as a single coil.

Spas and I were referring to dual coils before..

RE: How many wraps
Thanks gently - that sounds more like it - it is going to be very simple coils at first - my double twisted and quadruple coils can wait until tomorrow[Image: smile.gif].

RE: How many wraps
Funny thing is, all this trepidation will dissolve and evaporate once you get a few coils under your belt. You'll be a 'simple' style coils maker pro in no time.

I have nothing technically helpful to add to the thread since the masters already covered it, so I threw in a little rah-rah pep talk. I hereby name you The Conservatory Coiler.

Hi TW - Three lessons learned already. 1) Never drip juice straight down onto the RDA - this is what I did and some of the juice seeped through the centre pin and into the mod - stupidity in the first degree. 2) Never put lots of juice into the well of the RDA when vaping at low power - the wick gets too wet to work properly and you get little vapour. 3) Never put a lot of wicking into the coil when vaping at low power - you get the same result as 2. That is just one afternnon - a learning curve - more like a hairpin bend[Image: huh.gif]. Enjoy your day and keep up the humour[Image: smile.gif].

RE: How many wraps
I always drip straight into my RDA. The 13 Heavens has no center pin leaking problem. Plus, since I use the widest chuff cap, I don't have to remove it to drip. Wouldn't do so well for MTL to have a wide chuff cap though.

Yes, overfilling the juice well is an annoying little happenstance. I still do it occasionally and it irritates the heck out of me. Having to deal with that gurgling for 10 draws in a row kills me.

RE: How many wraps
The Kuro Koiler is great - no problems at all - so I am going to experiment. I need a reliable and reasonably priced ohm meter - any suggestions please.

RE: How many wraps
3mm ID is too big for low power vaping,  You'll have to take really long pulls to get anything decent out of it - and from your "too much juice in the well" comment, I'd say you're there.  2.5mm is even pushing it.  I'd go 1.5-2 for 28 awg over 1 ohm per coil.

Remind one liberal per day, that laws affect only the law-abiding.

RE: How many wraps
You'll need to hike the power up a bit to get the best from the larger diameter coil, it shouldn't impact overly on the vape temp, flavour etc.
Whats happening is the volume of juice is overwhelming the coil, having a cooling effect, its boiling rather than vaporising the juice. Trouble is if you reduce the diameter you'll need more wraps, risking dry hitting..  the balance between resistance and power altemetly comes down to the coil. Like AJ said, lower resistance will work better for 28g.

RE: How many wraps
Thanks for all your help and advice guys. I do not think that going below 1.2 ohms for MTL is going to be practical but we will see. The Kuro Koiler is not supposed to be all that good with wire above 28 gauge but we will see with that too[Image: smile.gif]. I think that under 1.2 ohms there will be too much vapour for MTL meaning it will be very short puffs and a lot of waste of vapour and juice not to mention the power but again we will see. I am going to have an interesting time over the next couple of weeks investigating all this and I will let you know the outcome. Don is kindly sending me some different gauges of wire to try - the folk on this forum are awesome with their help, advice and encouragement - thanks again to all of you.

(14-02-2016 08:50 PM)Spasmod Wrote:  28g 25 Jig (assuming you mean 2.5mm inner diameter) you'll need approx 11 wraps.

28g 30 Jig 10 wraps

I wouldn't be tempted to go below 2.5 due to potential wicking issues but if you do, below are the numbers

28g 20 Jig 14 wraps

28g 15 Jig 18 wraps

There's also the problem of actually fitting the coils in the atty... they do get wide rather quickly which makes it impossible to work with them unless you have a Velocity Styled deck Smile

There's a simple and very easy to use coil calculator here - http://coiltoy.ermeso.com/

What a cool tool! OH.. wait a minute.. it doesn't do SS.. Darn!
