Microcoils

[drstevo]

Guys,

How does one build a microcoil? I've tried with varying results. I really cannot get the coils so tightly packed together and this is after I flame them! I don't have a drill but but wrap them on a rivet that hasn't been punched obviously... they are reading around 1.1 ohms with about 6 wraps... I've read that around 10 wraps should be 1.5-2.0 ohms. That's what I am looking for. When I try it, I get crazy Ohm readings ranging from 5 Ohms to around 3.5 Ohms... any advice would be greatly appreciated.

I have watched youtube videos and still cant seem to get the coils as tight together so they actually stay together.


Kind regards,
Steve

First of all @drstevo what sort of final resitance are you looking to obtain? Also what wire are you using and are you looking at a single coil or using them in a dual setup?

Steve what Kanthal are you using. extra thin such as 0.20mm ( 32 awg ) is to thin and springy.
i use .32 mm ( 28 AWG ) .. flame the wire first with butane burner then wrap around a micro screwdriver ( or whatever you have handy, toothpick is a good one, a nail, rivet as you have or for tiny micro coils a blunt syringe needle ( from filling bottle) .
i do around 12-15 wraps and get around 1.8-2.1 ohms giving me a dual coil build around 0.9 -1.1 ohms

pics below to show you the results.. but after ive wrapped them i finger squeeze them first, then slide them off the item ive wrapped around and then using some tweezers ( or long nosed pliars carefully squeeze and flame them for a good 30 seconds or so keeping the pressure on. I use helping hands tool with magnifying glass so i can see up close too any overlaps or problems as im squeezing and flaming the coils
then once done slide it back on rivet/screwdriver/whatever your using. and fix the coil in place on dripper.
then pulse fire adjust and using pliars or tweezers give a few extra squuzes ( BETWEEN PULSES NOT DURING) .

end results is below

normally take around 10-15 minutes from start to finish for dual coils

Read this...http://www.planetofthevapes.co.uk/f...icrocoil-and-cotton-guide?highlight=microcoil

Then make sure you have .30mm kanthal and that what you use to wrap on is about 1.5 to 2.5 mm in dia

most important tool for microcoiling - tweezers!
This set-up blew my head off but I'm glad I tried it.

I have both .32 and .25 kanthal. Tried both ... im looking arounf 1.4 -1.6. I think my couls are just like standard as they dont bunch together even after torching ...
Im on the booze tonight so will check in in the morning lol thanks for your replies as always!

Hi All, a little help needed!!!!

Just got some .35mm Kanthal and it feels like fencing wire compared to the stuff I've been using. Is it too thick????
I've built a 10 wrap MC coming in at 1.2 ohms, which is where I want to be (maybe a wee bit low for me).

I just want to understand how this will effect my battery. I'm assuming it'll draw a lot more amps to heat the thicker wire??? ergo draining the charge quicker??

Is this stressing the battery more than a 1.2 ohm build using .2mm wire??? if so where is the edge/danger zone???

It takes a good 2 seconds to glow compared with my previous builds using .2mm

I'm sitting here looking at it, waiting to wick it up.... but I just want to be sure I'm not likely to overstress the battery or suffer some other ill affect of Electrickery!!!!

Thanks muchly

your not drawing any more amps so it wont stress the battery that way. only thing it will do is drain the battery slightly quicker simply because your powering it for longer to get the coils up to temperature. .35 may be a little thick, anything between .25 and .32 probably better. i use .32 and really should get some .28 as the .32 can be a little thick when dual coiling to get through post holes and can take a little longer to heat up over my original .20 ( which is to thin to make micro coils as is it is to springy and tends to overlap.

Thanks, I must say it's so much easier to work with. Once I gone through the 10 meter spool I'll maybe get some slightly thinner stuff!!!! Now to vape it!!!!!
Thanks again.
