Let's talk hardware

Not talking resistance, General. I was referring to thickness (size) of the wire.

I know. I see/feel a noticeable difference.

Here's what my digital caliper says:

Kanthal 32 ga. = 0.20mm (.008")
Kanthal 30 ga. = 0.27mm (.011")

EDIT: For the record...30 gauge has 82% more area than 32 gauge (cross section). I'm guessing (but could be wrong) that resistance is proportional.

Hmm.. I guess I'll have to wait until I unwrap before I can tell the difference..

Thank you for the technical details.

Do you think you might have been sent the wrong gauge?

Look up the spec for those two gauges Dust. Maybe I'll see what I can find too. I've seen it a million times but can't remember.

I looked up a chart (wouldn't copy/paste right) and my measured thicknesses are per the guide.

Question. I normally use cotton (peaches and cream) which never has an aftertaste and today I used an actual cotton ball. Does the after taste go away? I Dont boil or clean. Just used 1/4 the cotton ball to make my wick. There is a definite aftertaste and I can deal with it as long as it'll go away.

I don't know MP. I'm leery of using any store bought cotton products like cotton balls, cotton bandages, yarn, etc. I know most of these are supposedly safe but I still wonder. I buy real cotton wick and I boil it for 15 minutes and let it dry. I feel safe with that.

 

[MrPicC]

The yarn is stupendous bronze. The cotton ball I'll give till tomorrow afternoon to settle down. It's definitely better after an hour of chainvaping but not where I want my flavor right now.

I don't know why I even attempted it, but my first micro oil was a fail. Tried to rush through it while Chloe was doing something and it fell apart on me. Will attempt again at a more leisurely pace.

I just did a very tight 5/6 wrap almost touching with 28 gauge. Came out to 1 ohm and perfect as far as firing. My coil from this morning i ruined pulling the wick out. It was complete nastiness. I honestly think I've been using that coil for weeks and weeks.

Chloe and coils don't mix.

I think I'd rather have Chloe crawling all over me than make a coil anyway.

Ok, getting a little frustrated here. Waited until little miss was asleep, and sat down and put the coil below together. Pulses well, fires well, wanna take a guess at what it ohm'd out? 3 OHMS!!

How is that possible? What am I doing wrong here? I wrapped it around a micro screwdriver that is around 2mm in size. Or did I not receive 30g Kanthal?

General does your 30g coil look like that?

 

[MrPicC]

That coil looks awesome. That gauge has to be wrong though for such a high ohms right?
How many wrap dusty?

I know right?! It's a 9/10 wrap of 30g. Pretty sure.. Let me see if I can zoom in on the coil and count it better.

 

[Dusty_D]

Yup, 9/10 it is..

 

[jwhorner6]

A 10/11 wrap of 28 around a 2mm gives me 1.5 ohms

Either use less wraps or wrap it around something a little thinner

Yeah, I think I'm going to need to go thinner.

Dust....looks right to me...best I can tell from a photo. Do you have a caliper to measure that wire? At 3 ohms it would seem you got 32 or 34 ga. Yes, I had 10 wraps of 30ga. Your coils look squeezed together and all.

 

[tntmux]

30awg=0.25mm
32awg=0.20mm
I am also going to try this micro coil, but I have to buy some cotton 1st.

Digital calipers next on the pick-up list. It seems like it's a requirement if I'm going to continue doing this stuff.

I did sign up for the Microcoils thread: http://www.e-cigarette-forum.com/forum/rebuildable-atomizer-systems/416271-micro-coils-increase-vapor-flavor-th.html where I found our usual suspects from the Natural Tobacco thread (Jerms, Johni, etc..) and the concensus was that I used too large a wrapping element to build my first coil.

The coil itself is good, and amounts to the right ohms for it's size. I just have to use a smaller screwdriver or drill bit to wrap the coils.

I've got 1/16 and 5/64 drill bits at my disposal and will attempt to coil on those instead.

Yeah, the beauty of micros is that you can go with a low gauge and get a resistance that is a lot higher that any traditional coil with the same wire. A 2 ohm 28g micro should give a better vape than a 2 ohm 32g.
