Kayfun Lite General Questions

[thatrandy]

Im thinking of buying the kayfun lite (clone) from fasttech.
I have a few general questions

1- when building my coil, I want to be around 1.4-1.8ohms, what gage wire should I use?
2- what size drill bit should I use?
3-will a regular needle bottle (like https://www.fasttech.com/products/3099/10002091/1425400-e-liquid-refiller-bottle-for-electronic-cigarette this?)

I love mine. I use 28G KA1 and build between .9 and 1.5 ohms. And yes, that will work, but ALMOST any slender tip bottle will fit in the hole. No need to go with a needle tip. They are a PITA to fill a 5ml tank with. Takes forever and you have to let go and let it suck back some air a couple of times. Which brand of clone are you thinking?

 

[Hans Wermhat]

I build at 2mm, 6 to 8 wraps.

1: 28 gauge kanthal a1 ; or 30 gauge
2: 2 to 3 mm
3: yep those should be fine; those are 10mm; i bought a 10 pack of those, but I never use them; i use the 50mm version.

This is very useful - Coil wrapping | Steam Engine | free vaping calculators

Love mine too, filling with a dropper is a big pain. I pour a touch of juice into tupperware, suck up with a oral medicine blunt syringe from cvs and fill away. Much easier.

An ohm meter can be acquired for $10 or less and is a smart investment.

Have you considered Kayfun V4? I never used Kafun lite because it is fillet though tiny hole with screw. I do not like idea of such complicated multi-step filling:
1. Unscrew a tank from a mod.
2. Find a screwdriver.
3. Unscrew a screw.
4. Fill using needle-nosed bottle (painfully slow).
5. Screw a screw back.
6. Screw a tank to a mod.
I should say I cannot compare kayfuns lite and V4 on performance and ease of wicking.

 

[Hans Wermhat]

The V4 is a dual coil with about 732 parts. Not really a good option for a beginner. OP is asking all the right ?'s so I'm assuming a basic knowledge of coil building and safety? Right?

1. 28g kanthal A1
2. 2.4-2.5mm is what I used (3/32" bit)
3.. it fills quickly with a plastic tip bottle or you can use the metal needle tips.

 

[roxynoodle]

I would call the v4 a single coil atty. You can build it dual, but should probably put the subohm kit on it.

Slender Tip Bottle - One Stop DIY Shop Store, LLC
I use this type of bottle. Works faster than a needle tip.

A 9/8 wrap at 2mm using 28ga Kanthal A1 should put you in the 1.5ish range.

I’ve been building with 28 ga wire around 2.5 mil pin w/ 8-1/2 wraps = 1.5 ohms.

When filling I never use the screw in the bottom. I cover the air vent on the bottom with a finger, unscrew the top, almost fill, catch a couple of threads to reassemble, turn it upside down & open the vent, & take a couple of hits while it is still upside down.

Easy & toolless. You’ll love that Kayfun.

No, it is single coil.

 

[Hans Wermhat]

If single coil, then why the extra screws? Not bein a "richard", just askin. Knowledge is power.

 

[Hans Wermhat]

Ad how do you keep it from flooding with the juice holes on both sides of the deck? I been thinkin bout gettin one, so askin lots of questions.

 

[Alien Traveler]

Extra screws are just extra screws (you may consider them as spares or, if you wish, you can mount two coils). Holes on both sides provide juice to a (single) wick. No flooding because of (I believe) vacuum in a tank, only capillary action. I do not have leaks and I always store my mod (and tank) in horizontal position.

And you can to put a new coil without emptying tank. Just unscrew tank (when it is upside down), unscrew chimney and you can do your work. I even do not take it from a mod usually.

I get what you're saying, but im trying to stay within a certain budget, especially for my first RTA
