Well......There's my problem I guess.

I was afraid that anymore than that would brake the wire. 3lbs doesn't sound like much, but I thought it was quite a bit hanging from that tiny wire.

If I was using dead weight, I'd find the breaking point of that gauge wire and then remove a pound or two.

Yeah, I don't think 3lbs is enough weight if your going to use dead weight. I believe another poster had tried 20lbs (kept breaking wire) and settled on 10lbs.
I know I'm pulling with more force than 3lbs for sure.

I just tried 10 lbs...snapped my 28g Kanthal A1 before the first wrap.

These are the tensioned coils. Again, I torched them clean and tossed them in my reusable coil bag.

This is the basic jig I used. My mandrel (screwdriver) chucked into my power drill. The coil clamped to the mandrel with a needle nose vise grip. 2 large vise grips clamped to the spool hanging from the mandrel. Then, of course, I slowly turned the power driver to wind the coil.

That's the weight of the vise grips I used for tension. Approx. 3 lbs......Maybe that's not enough?

Jef I didn't see ya post on the tensioned next thread or I would have made time to get to ya. Does sound like you didn't get to adhesion. That's the point the turns get closest together. You know with a micro when you get turns close you'll gunk. Like a loose post connection. That's what super_x found as he got to the contact coil. It's like a continuous short, a close contact coil. Torching them and squeezing 'em gets 'em tight enough to oxidize together and get stable. Then you see some serious output and they run cleaner.

Problem is there's still gaps in 'em that can reduce the output. We def want the best output but not at the expense of dry heat. Winding them with tension gets the wires as close together as they can fit. You have to apply just the right amount of tension. Too much and you can over-stretch the wire and you get hot like the short again. So there's no way around it, we each have to learn where the middle of that lane is.

Here's what you get when you do…as good as oxidation as you can possibly have. That means the closer to the natural resistance capacity of that particular wire. Man, don't get any better than that. You're not underusing the wire; and, you're not over-stressing it. That's what doesn't waste your juice or amps and likely best matches the load capacity of the wick that fits in it.

So let's have at it Jeff. I'm a big tobacco lover, vape high vg or 100% and I've got over 60 of these things all running tension with every kind of juice. Some I've had running six months, like this one…

This is what she was doin' at 5 mos before a rewick mid-Dec.

Come the 6 mo anniv, short of time but I couldn't bear to take it down.

What we're talkin' about here is the most efficient electrical delivery. It's the most efficient electrical/combustion we seek in an engine and for the same reasons.

So bro step up. Invest a little time in this and you're gonna be able to apply this to anything and everything, simple or complex like the above. But you gotta find that zone where resistance is optimal.

My suggestion is start simply using the drill as a winder and hand hold to get a feel for the wrap. It's harder on a drill than a pin vise or screwdriver but it can be done. You're lookin' for the point that the wire starts to pull in on itself. We affectionately call it "sticky". But not much further than that. Once you get there which might take you a few tries pulse it at low voltage and repeatedly. Don't fry it in the white zone. You want it to oxidize in steps like laying on multiple layers of paint. It builds denser and harder that way.

I'd keep the diameter someplace reasonable. Not huge, makes it harder and more practice. Say 3/32" to 7/64", not over 3mm to start.

And that's it. It really isn't more complicated than that. Just takes a little bit of patience. But it will prove about one of the most dependable productive winds you're likely to do at whatever resistance or wind style you choose.

Don't hesitate to tap me on the shoulder if you need help. Glad to do it bro. Look me up or super_x on that thread you were at.

Good luck and take care.

:)

7 lbs worked.....I just made 2 tensioned coils. 1 as a contact coil, the other as a spaced coil (just for experimentation)... I will try them out for a day or so and see how it goes.

You just spent all that time and energy to construct a tensioned coil, and you're not "chomping at the bit" to try it?? I'd have that contact coil running already for sure!

Hell I made probably 20+ coils today to experiment and get the technique down even better. I did 30AWG twisteds, 28AWG twisted, 24AWG duals for my MutX, and a whole bunch of others that ended up in the round file. I had a few issues, like making identical coils only to realize I was winding the wrong direction for my posts to not push the coil out of shape, hot legs, etc. But I'm learning fast and thoroughly enjoying the vape that a tensioned coil provides me!

Many great ppl here more than willing to help out and critique when needed! Stick around!

Hmmmm... that's a great theme for the TMC thread: "Stick Around"!

Lol @Darryl Licht

I'm vaping one right now. 7 wrap 28 G 2.4mm, tensioned 7lbs. 1.3 ohm

Not bad.....I am noticing more flavor....cooler vape....big clouds

I'm gonna use it for a day and let it really break-in before I get too excited :)

After a week of hard use my twisted coil was still pretty with no build up. I changed it simply because I got my Temco shipment and wanted to play!
Here's my latest build: 28AWG, T2, 8/8, 2.25mm, TP=0, LL=9mm, t.m.c.=0.7Ω

I'm loving the vape on it right now!
The last of my "The Milkman" eliquid is going up in smoke (I mean vapor). It's an incredible flavor, if you like vanilla milkshakes and strawberry pop tarts!

Welcome to the wonderful world of tensioned flavor and density!

A little late to the party on this one. Just got the Sub-tank Mini late last week and put the first build in it yesterday. I must say that I was rather surprised and impressed that an atty as inexpensive as this is sure does produce an excellent vape.

Dual twisted 30g nickel, 7 wraps, 3mm ID, inverted coil, wicked with KGD.

Not sure why I put the coil in upside down. Saw the stock coil like that and for whatever reason, ended up doing it like that. It isn't affecting the vape in any adverse way.

kstm1.jpg


I took a 3/8" piece of KGD, removed the backing on both sides, folded it in half and gently rolled it up. Then just cut it right where the threads for the barrel are and fluffed the ends up.

kstm2.jpg


Placed the barrel over the coil and wick (it kind of folded the wick down) and tightened it. I didn't touch the cotton. Didn't try to stuff it down or move it away from the juice channel. Just placed the barrel over it and screwed it down.

kstm3.jpg


My settings. Resistance is actually reading 0.10Ω this morning.

kstm4.jpg


Absolutely loving this tank. Super easy build. Easy fill. Wicks great. Adjust AF on the fly. Produces great flavor and decent clouds. What more could one ask for?

Why does one person need 8 of the same mods?

Color coordinate with your outfits?

I like different juices in different atties and don't like having to switch atties all the time. Not only that, but I am a Vapor Flask collector. I own every Flask made except for a V1.

@ $300 a pop, that's an expensive collection!

... and unscrewing an atty is so challenging! LOL! :D
