I call it..."My Mod" !!Warning...graphic intense!!

Thanks guys...still learning myself though. Like I tell my kids when they freak out about a big or complex jobs...break it down in to small parts...figure out each component and then put it all together. Well it sounded good anyway!!

Going to try to make a VV in one of these...I'm want to mold a pocket on the back side with a cover over it to mount the booster and a digital pot...with the adjusting buttons flush mounted. Just have to figure out how to mold the damn thing from scratch without the pockets breaking thru to each other. Also want to have rubber grips molded in on the rounded ends...but that will take some doing considering the front cover will be held on by bar magnets in the center web. The VV would be something like this...even though I dont have the drawing finished either....

Awesome job, Nico!

One thing, what about the V shape on that coil? I know you've explained it before, but...

 

[nicotime]

Oops...forgot that part didnt I...thanks Sci. I wound it that way because I wanted the coils ends to come out level without moving one post up or down....I know I'm .... about stuff like that but it makes a very neat coil....and in doing so when testing them I found that that "reversing" loop in the center makes the coil hotter in the middle..I guess from the tight loop. I started with a "U" shape around a .040" drill..then laid it perpendicular to a 3/32 bit and wound around that..winding both sides of the wire at the same time.

This is a video of how I wind the coil...its scaled up using regular coated copper wire and a plastic tube so you can see it better.

 

[Sci]

Thanks! I can't help but thinking that could be an easy way to make a DC also.

But is that a good thing?

You mean by using the center loop say as a negative connection with two positives at each end of the coil?

But is that a good thing?

I tend to think so Willy...on a dry burn like in the closeup pic on page two...you can see the coil is hotter in the center most coils...but on a wet coil it cools the coil that touches the wick but will still get red hot near the posts connections since its not cooled there...so I would rather have the heat focused in the center. I have yet to burn a coil in half yet...but I dont do hi volts either..so maybe once I get a VV booster in this thing and crank it up that may change. Does it have to be wound that way..na...any way would be fine...I just like it for the way it sits in the post neatly. I mean its not a drastic difference anyway..just something I kept noticing. It may just be me entertaining myself and dreaming that I know jack!

Have you seen where the IAtty folks are actually twisting two pieces of resistance wire together, then making the coil?

Some folks on the UK forum are doing it with their Bullis.

His vids are quite rambling it's lined up where he starts.

Huh...wonder what the purpose of that...all that to make a stronger coil? Its hard to make out what he is doing.

A while back I was playing around with wrapping a 40ga wire around a 32ga like a guitar string and then winding it into a coil around SS mesh...theory being that it would keep it from shorting to the mesh due to the current taking the path of least resistance thru the 32ga....but all I ended up with the resistance being all over the scale.

Maybe thats their idea of a dual coil...but I think they would start seeing hot spots in the coils after it gets some gunk on it....dunno.

This one shows it better once you see the link above. It's not English, but it should be clear I think.

It seems the point is to extend the resistance wire with normal wire so that there are normal wire "leads" for connections and the nichrome/Kanthal is only touching the wick.

Wow I explained that poorly!

I see...for a no solder connection right? I thought he was twisting two nichrome wires together.

I'll take my solid mechanical contact...even before when I ran the nichrome down a brass tube and crimped it it would get a hotspot at the connection due to the resistance. IMO...if its not soldered or mechanically biting in to the wire... liquid will get in between and form carbon from the heat cascading the high resistance problem.

He is in the first vid, two pieces of resistance wire tightly twisted together, then formed into the coil.

I wasn't referring to how he attaches non-resistance wires on each end of the coil.

Some foreign guy talking about the technique:

For me, the best result gives the twisted coil ​​wrapped around folded 4 times silica rope.

and twisted coil with fiberglass wick on top, as Imeo does

Like this:

Can you see any benefit to that rather than say going to 28ga wire Willy ? Of course I dont know what he is going after either...making a stronger coil...altering resistance..more surface area...or what. Have to give it a try I guess...did it say what gauge he is using?

 

[WillyB]

They don't talk gauge. It's 0.13.

 

[nicotime]

Dont see much difference...here is two 36ga twisted together to make a 2.8 ohm coil...acts just like a single wire coil. I wonder how long it would last or if it would self clean due to wire creep?

 

[WillyB]

You've vaped it?

 

[nicotime]

No...maybe I'll trim it down and throw it in the next cleaning....I run mine at 1.7-8 ohms. I just dont see any advantage to it over a single coil of higher gauge..unless you dont have a variety of sizes around.

 

[WillyB]

Well sometimes there is more to it than meets the eye. The proof is in the pudding.

There have just been too folks raving about it, the latest on the UK forums, claiming all sorts of vapor improvement etc.

I know you like to tinker.

 

[nicotime]

Oh yeah...I agree....I will be giving it a try for sure. I thought I saw on his video or somewhere where he was putting wick over top of the coil also...that I know increases vapor...I was doing that way back with the CE2 crap...bringing one of the strands of wick back up over the coil...helped with the leaking issues too. I still have about 12 boxes of those things I dont know what to do with..I dont even use 510 connectors anymore!

 

[WillyB]

With the whole new crop of rebuildables we'll see lots of different approaches. In Mr GG's vid I think there is no wick in the twisted coil, only on top.

 

[nicotime]

I caught that too..seems like a waste of heat unless the coil is flat or you have some kind of reflectors in it like radiant heating systems do.

Yeah you never know whats gonna come thru that door! lol
