Alexander Mundy's Magic Twisted Ribbon

[gdeal]

No, not a surprise. And it was very cool of you to make something up for the mechanically challenged (←jk), the variably capable (← and there too). The only reason I even compared, was that DrMA was having trouble getting a decent vape out of the stuff, and I/we had no idea how close one could get to begin with. Now, I might have a better perspective, to say . . .. "oh, that is/isn't what it should be like" . .. . . or "that's not the wire, that's your build". . . . 'n like that.

All good. Just didnt want people to think.."oh I dont have sub-ohm hardware, so I guess I cant experience the magic." Two wires is like an appetizer, three wires is the seven course meal.

So what's the verdict on the 2 vs 3 wire MM twist? It sounds like they're close, with some minor differences around the flavor depth.

I think most people will find that head to head, the three wire outshines the two wire significantly; Taste, vapor density, volume potential and eveness of flavor.

But it depends upon how your like your vape or want to vape.

For example, I have a two wire in a Taifun GT that vapes beautifully. Is it a fog monster? Not even close, but with the internal atty configuration of the posts/airtube and chamber dimensions it has worked better than any round wire set-up in the same atty. The small chamber and airflow dymamics just plays better with a narrower coil that you can get with a two wire. The three wire micro coil felt like it was getting a bit choked off and vaped much hotter. This atty is more for longer draws and a longer vape session.

On the other hand, I have a Trident Dripper, that is killer with a three wire at .5 ohms with a ~1.8mm air hole. The flavor is off the charts along with vapor density and volume. But I dont sit down with it for a long vape, it more like a couple of hits and I am done. (done as in completely satisfied...with that inner voice saying just walk away for now.)

I would put this in the you gotta try it and see what works best for you bucket IMO

By the way I'm still try to get to time with the diamond bit tools to try a fully embedded MM wire coil like the one you did earlier in ceramic.

The spiral channel is difficult to dig with a cutoff wheel. I used the tool shown below:


It's about 1mm diameter, cylindrical router tool.

Cool idea I can't wait to try it.

thanks Terry this baby is soo tasty

that baby's got teeth already.

so, I have been playing around with MM for a few days now and I am having trouble dialing in a good vape, and I know you guys can steer me in the right direction.

First, the flavor is unreal with this stuff! I love it.

I seem to get a lot of popping, and not a lot of vapor. I know vapor production is a little less than a standard micro but I am getting much less. My first set up was 5 wraps around a 1.4mm piano wire, measured out to 1ohm. The vapor production was actually pretty good with this set up but it took too long to heat up, and as soon as it got to temp there would be 1 loud "POP".

I got a peach tea flavor and figured I would want the vape a little hotter so I took 1 wrap off, so I now had a 4 wrap which measured out to .8ohm. Flavor and warmth of the vape were spot on, but now this thing pop's like Tommy Gun from a 1950's gangster movie, making it very hard to vape. The TH is also too much for me now. On the first coil I dry burned and lightly squezed, and the second I left a little gap between coils. Is the popping from not compressing? Do I not have enough wick? Did I not interlock the 3 sections tight enough? What could help me get a nice warm consistent vape with no popping, and low TH? I take 3-5sec drags.

I have found some juices pop more than others.
Also occasionally I have a coil that pops and after a dry burn, squeeze, and new wick no pop.
I know pdib prefers not squeezed so I don't think that should be a problem.
I am sure he will chime in about that.
I like a 6 turn on 1.2mm form for .8 ohms, but pdib likes a lower resistance less wrap larger id so it is "to each his own" there.

Can you scan the wire on a scanner at 1200dpi?
Something catches my eye but the resolution of those pics doesn't let me put my finger on it.
Maybe nothing, but I can't tell.

 

[pdib]

SeaNap, Your resistance is higher than what I'm getting. If I do a 3/4 wrap on 1.5mm, I'm under .5Ω. You should pro'ly be around .6Ω, if your "4" wrap looks like 4 on the posts side of the coil and 5 on the airhole side. I can't see it so good either. If you don't have good macro gear, or a 1200 dpi box, you could always send a nip to Mundy (or me, but he's the expert) for "consultation".

 

[SeaNap]

Sorry about the low res, thats all i've got to work with. I'm positive that its just a bad coil. I will twist up some more magic tonight, I think my problem is when reverse twisting the 3 strands, in Mundy's video I counted 17 reverse revolutions. When I do that it doesnt look like all y'alls, so I had been twisting it more (almost double). I may be over twisting, or I may not have enough tension to interlock them. Trial n error is the best medicine, just wondering if y'all ran in to excessive popping before.

My ohms are a little off, but I did have some long legs and my meter doesn't do hundredths so I could have been around .75ohm ish. I've got a couple thousand dollar portable Fluke O-scope and you would think that the accuracy of the resistance meter would be better than just .1

Thanks for the advice!

So I just wanted to report back in on a set up that I have going for the last two weeks with daily use. (Initially posted here:http://www.e-cigarette-forum.com/fo...ndys-magic-twisted-ribbon-7.html#post11113992

This coil is still going strong, I havent even changed the wick yet. So while I know your guys change your coils by the hour, I am going for longevity. As long as its vaping the way it is...its not going anywhere. Too many other toys in the vape chest are keeping me busy.

Great stuff Mr Mundy. This wire is the standard bearer for vape optimization.

Its .... ugly at this point, but still vaping great (and yes, taste has not diminished yet). The hemp fiber is kickin azz.

Yowza!!!!!!!!!!!!!!!!!!!!!!

 

[SeaNap]

gD, Thats great to know that this stuff can last and still keep being a flavor machiene!

UPDATE:
So the coil that was popping, I totally didn't reverse spin long enough and the 3 strands never fully interlocked

Working fantastic now!

Gotta call it when you see it and give appropriate props.....

Glad you got it worked out.
I was wondering if the folds had opened up or not but couldn't really tell by the pics.
I suspect the folds were still semi closed and the popping was coming from inside the little cylinders because not enough juice was getting there and the temps inside them were excessive.
BTW, a really cheap way to do macro (at least enough for these purposes) is to hold an eye loop or 2 stacked over the phone or IPad camera lens.
That is how I do all mine, think I paid under 5 bucks for a set of elcheapos at harbor freight.
If I need real detail of wire I scan on a flatbed scanner at max resolution then crop that to a reasonable file size.

Nice to see it is still cooking and working good for you gdeal.
One of these days I will be able to get a second Reo and not have to change wick so often.
I get bored with the same flavor in my daily mod.

 

[pdib]

Farking vape heaven. (@.3Ω) Flavor is shooting out of my ears.









btw: I've noticed the Mundleberry Wire is very easy to shape with just one light torching, it really holds it's form and is quite malleable like 'at. I find I just approximate the shape I want, torch it, and then it just does what I want and stays there.

 

[gdeal]

Whoa...pdib. I dont think I ever had a coil pic talk to me. If you listen real close..you can hear its saying "feed me".

About how long are your button presses? Also whats you airhole sizing/configuration for that setup?

 

[DrMA]

Very nice, pdib! However, I have reservations about the safety of going so low on resistance. That thing is but a hair away from a dead short...

 

[pdib]

Yes, well, with the amp rating on my batteries, I'm not pushing the envelope or stressing them. I'll usually run a new set of batteries through multiple charge cycles before deciding (guessing) that they seem solid and aren't somehow substandard and trust them re: specifications. According to manufacturers specs, and these tests Test of Samsung INR18650-20R 2000mAh (Green) I should be able to run these at 0.185Ω and still be within recommended range. Good point tho, DrMA.

It does have a bit of heat up time. Not once you're vaping; but when you come back to it and start vaping again. This is mostly why I'm at .3Ω. I think if I put one more wrap on each coil, I would find the heat up time to be not worth it. Given that the build takes about 1 sec. to rev up, the button press is normal . . . . 5-6 sec. The air holes are factory, 1.2mm This size is ideal because, given that the airflow is doubled, I can have a big effect on the vape with small variations in my rate of draw. I can draw lightly and little, for TH; or draw pretty hard for a pretty harmless vape.

It is a limited window for duals and heat up time with the Magic, tho. I had René41 in there for my first build on it. And, performance wise, it was perfect. Flavor wise, tho, it weren't no Mundlebloomers. I think I'll hit it with a 26g Nichrome, just to round out the comparison. Also, I might add a wrap but tighten down the ID a bit. This one was about .060" (#53 drill bit). Maybe something like a 1.2mm like Lexi likes . . . ..
