Kayfun Moe Svesto?

[GrandPapa]

Hi,
Picked up some new equipment a Kay fun lit (i believe) as mentioned in the title, and a Dripping atty, and a Stingray 18650 mod.
Now I am trying to figure out a # of things.
My KayFune leaks through the airhole!! Some help there appreciated...
and wht relationship th # of turns on Kanthal 32 gauge wire produces in the OHMs relationship. I have been to the ohm calculator site
and watched videos, but can't quite figure out the relationship to # of turns to ohms produced.
JIm
p.s. I am an old fart with a hearing problem so some of the audio is not that good.

That'll be a Svoemesto Kayfun, assuming you got an original and not a Moe Svesto copy...

Leaking of the kayfun is almost always caused by a lack of vacuum in the chamber. Remove everything and re-assemble, paying particular attention to the O-rings making sure they are seated correctly.

The amount of cotton you are using can also cause some leaking. It's a little tricky getting this right - make sure you don't push the cotton down into the juice channels when you are wicking your coil. Watching videos and experimenting is often the only way to get this part right.

As for the 32 gauge kanthal and the resistance, it really depends on the diameter of the item you are using to wrap them around and how close your wraps are together.
32 Gauge has a resistance of around .86 ohms per inch, so it's quite easy to calculate from there.

Did u top fill the kayfun or fill it through the hole on the bottom? Also for the ohms per wrap for a coil check out vapors tool box. It is an app for your droid or iphone. This will tell you how many wraps you would require with the gauge wire you are using. You can adjust the diameter of the wraps plus the quality of wraps depending on what ohm you want. To figure out exact ohms per each individual wrap would require some more math. Basically each Guage of wire has an ohm per inch rating.you can find charts online. Depending on the exact length of wire it takes to complete each wrap.(the circumference of what you are wrapping around).

Quantity not quality^

A lot of people use this coil calculator.

I would advise an ohm reader to double check your finished coil though.

Welcome to my Nightmare. This is a recent thread because I had the same problem. It's not long but it is VERY informative.

You need an Ohms meter for that. Even if you use the calculator it's more of a guide - only the ohms meter can tell if your build is sound or if you're gonna have a problem when you put it on your battery.

Good luck!

Hi Pyang,
I have been there some of the # they ask for I don't know for sure....I have no idea how to find them out....What I want to know (in simple terms) is does the # of wraps of X gauge wire increase or decrease the "ohms' resistance? I am an old man that has been outta school for a long time LOL

Here's a simple way to understand coils/ohms relationship. The more wire the current has to go through, the more resistance there is. Lower gauge (smaller number) is thicker wire, therefore more resistance than a higher gauge (thinner wire) for the same length of wire. Coil diameter only affects in terms of physical placement of a coil for a given number of winds and size. For example, winding 11 winds of 28g Kanthal with an inner diameter of 3/32" (smaller coil) would give 2.0 ohm while the same Kanthal, wound to a diameter of 3/16" (larger coil) would require only 6 winds to achieve the same 2.0 ohm.

It's always about how long the total wire is; bigger/smaller coils, more/less winds is just a way to get the length to fit how and where you want!

Completely second this. The theory is all well and good, but confirmation is king! Following a gourmet recipe does not mean hat you end up with a gourmet meal!

Hi Iamthevoice,
Great that is what I am after...I can get my head around that..many Thanks!!
And thanks for the link Avid...to the Kay fun leak thingy..

Couldn't have said it more simple myself.

Just to add (if you didn't already know) easy way to get that "almost perfect" inner diameter it to wrap your coils around screw drivers/drill bits. I prefer drillbits, ie. That where the 3/16, 3/32 comes in. They refer to the drillbut sizes.

You're very welcome! And may you not have to try all those things! lol

Thicker wire (smaller gauge) has less resistance then thinner wire (larger gauge).
