Tensioned Micro Coils. The next step.

[etherealink]

Just a quick look at the coils from last night after modifying my pin vise set up with a longer rod and making some adjustments.

And here is the best fly reel I found for the price at Cabella's, the Wind River reel:

if I was going to spend that I'd get this:

ALS 0 1 2 1 BB CNC Anodized Aluminum Cmpact 1 1 Trout Fly Fishing Reel 40mm C905 | eBay

really compact

The cool thing about those WR2 reels is all the holes around the flange - they make trapping the wire when not in use a breeze.

Mine was cheaper in the store - like $20.

I hear yah, looks like that's a nice thing for sure but it's over twice the size... 40mm spool VS over 90mm. can't help it man, I'm all about compact as possible

Dead Weight Experiment with the Coil Gizmo



After work this afternoon I got a chance to mess around with the gizmo for the first time. For $3 I picked up the pieces at the local hardware to make a way to attach wire to a few of my 2 1/2 # plates from my workout room downstairs. I cut my piece of wire just long enough that it doesn't touch the floor when with one end secured in the thumbscrew hack and the other twisted through the eyebolt. I get the first 1/2 turn while holding onto the weight plates then once it's all still I let the full weight pull and wind the wraps. Works like a charm.



Technically it's a mini coil not a micro coil as I wound it on a .078" diameter mandrel I fabricated from music wire I also sourced at the friendly True Value. The weight was 7 1/2 pounds and I can totally see the adhesion introduced to the coil from the tension when I handle the coil. Mounting the coil was a piece of cake on the Subank mini's deck without putting any strain on the legs at all. That's what concerns me the most is keeping the integrity of the coil's form and adhesion undisturbed while mounting into the device. In order to realize all the potential of the tensioned coil it has to fit into the atomizer without any stress pulling at the coil from the legs.



It's 27 gauge Kanthal wicked with Japanese cotton and I've been vaping on it while writing this post. It is for sure as good as the twisted build I had in the atomizer.

A hanging weight is the most consistent you can get. A reel can only hope to simulate that, but does the job pretty well I think

7.5lbs makes sense, I'm thinking anywhere from 5-15 at both ends of the range, some nickels may need a little less than 5lbs too, Renne 41 prolly needs around 25 pounds

 

[turbocad6]

I'm also finding that even if a coil is made perfect it's almost impossible to mount it and maintain that perfect contact on the first and last wrap. Was always an issue even with formed wrapping but then it wasn't a big deal because wasn't shooting for perfect and was good enough. I suppose this is good enough too but I'm thinking a tool needs to be made to keep a tensioned coil under tension until its mounted. I built the solution in my Head already just need to eventually actually build a pair

I see it too. It's like pliers that are normally closed (you squeeze them to open them) with a female receiver on one side for the coil and male on the other so when you unsqueeze the pliers the coil is held in perfect shape until you mount it then you squeeze them and it releases.

Is that what your thinking too bro?

 

[turbocad6]

yeah, or maybe even like a locking forceps type design to be smaller and lighter. could be like a spring clamp type thing too. I got a few different ones built in my head now

That's awesome. I'm going to check ace hardware to get all the parts to put on the coil gizmo and definitely going to rig up some weights and do this. Great job!
I've only got some 10lb free weights my wife uses but hopefully can find a way to attach wire to it. Maybe some type of hose clamp, maybe the screw would catch the wire too.

 

[turbocad6]

here's a tension coil I mounted with really short legs, the 2 outer coils are pulled out a bit on the bottom. when this coil lights up the coils all light up at the same time except the 2 outer which lag behind a just a bit

does it make a difference? would clamping the coil tightly while mounting it even help much?

Two for you, one for me ?

 

[rowsley]

What about a small bolt and nut/ washers into the coil tightened up to keep it stabile so you have both hands free? I'm just throwing ideas.

 

[turbocad6]

would be too tedious and time consuming, plus the threads could distort and catch a coil going in or out. I'm picturing something that just clamps in place and then releases to remove it. small and light enough you don't have to even hold it ideally

 

[rowsley]

I gotcha.

Last idea lol

I'm headed for bed. Hope you guys figure something out. Good luck

 

[rowsley]

I just rigged up a 10lb dumbbell. Hopefully this will work. Basically used larger version of what's on gizmo. Hose clamp and a vinyl coated clip. To hold it all together.

my only other concern was did you have to beef up the gizmo or can it handle the weight? Thanks

 

[TheBigE]

That looks good rowsley. 10# may be too much. You'll just have to try. The gizmo gives just enough clearance to let the wire hang straight down without touching the table edge. just let the weight down easy as you start the first wrap. With the 7 1/2 pounds the gizmo held fast on its own. Just keep the coil close to the gizmo because it bends the rod easy.

That kind'a dead weight is likely overkill row. Hell, I can't even lift it.

Look the point of minimal adhesion is what you want. It's a measure of tightness, not the max that can be applied without breaking the wire. Not sure why the convo's headed down this road. The wire has a res rating and that's what were shooting to optimize to. Let's get to first base for starters.

Over-tightening wire stimply strains it beyond it's capacity, ups resistance. As power is applied this stored energy acts as a multiplier significantly increasing the heat of the coil beyond line resistance. Yep, you'll get a super hot coil…post to post. With a thermal output in all likelihood higher than the wick's geometry can handle.

Being able to enhance the thermal uniformity of a wind is an incredibly potent tool for matching the output of the wire to the capacity of the wicking media for a given power range.

Pushing a wire beyond it's rated heat resistance by strain may produce a great deal of vapor diffusion but it's optimal transition phase efficiency we're after…max vapor. A t.m.c. is a benchmark for the optimal vaporization zone that can be created by the three above factors.

We're not gonna get to the dense chain of plumes with the trick set up plugs we'd run at the track. We may leave a lot of rubber at the lights tho.

Good luck all…and watch those spaces.

 

[rowsley]

Lol Yeah 10lbs was way overkill broke 26g every time. I'm gonna try a 5lb now since that's all I have to work with.

If you can find some way to dampen that weight, mediate the force, that is very helpful. It's a lot of weight for the gizmo. It's a lot more weight than one might think as you have to consider the downward force of air pressure/sq. in. on it's surface as well to calc the total force applied. And too much will mess up your vape. Reals.

Good luck.
