Attack of the (Kayfun v4) Clones!

[FOG clouds]

I've developed a preference for spaced coils for a couple of reasons. First and foremost, they seem to deliver better flavor for the kinds of liquids I prefer. And secondly, time between re-wickings is increased for me.

The downside is that they usually need a little more wattage to come up to temperature as fast as a microcoil.

Current build in my Tobeco is 26ga kanthal, 2.4mm, 8 spaced wraps for 1Ω. I have the 4S kit installed for better airflow and enjoying this one at 22-24 Watts.

i'd have to agree with this. I also think spaced coils wick better. way less chance of a dry hit

Thanks everyone.I had seen a good deal on the Tobeco so I just wanted to check 1st. So Tobeco it is.

I know...

My question is, actually, what are the disadvantages of using spaced coils? I'm a low wattage vaper, MTL, and I've been vaping long enough to remember that we all started with non-touching coils, hand wrapped around a length of silica rope (often with a sewing needle threaded through it for stability ) or a screwdriver. What exactly was wrong with that method? We used higher resistance wire, smaller coil IDs, and we were happy.

I don't even remember why I switched to microcoils. Probably because everybody was doing it.

Given your preferences, it sounds to me like a spaced coil is right in your wheelhouse.

I used a couple microcoils when I first started vaping, IIRC that was how they did it on the video I happened to watch. I soon had switched to a spaced coil mainly because it required less steps and was easier/quicker- and when you are switching between 6 or more attys, saving a few minutes per atty adds up. Now, if I could detect a better vape from a microcoil I might still make them, but for how I vape I cannot say a MC does anything better than a spaced coil.

Good luck, Ant, and keep us posted.

BTW, the Tobeco comes with no spare parts whatsoever--not even one lousy o-ring, so I suggest you get some--you'll need them, sooner or later. This is the best deal, but it will take months to arrive at your doorstep.

What kind of wick are you using? The nice thing about micros is that they are much easier to wick with cotton because they are so sturdy.

 

[cobalt327]

I use rayon exclusively. No problems wicking- even when using 34 gauge Kanthal in Kanger PT2 heads.

BTW, FT also has a repair kit w/O-rings, it doesn't include #'s 9, 11 and 20. SKU: 2095702.

Or... these cheeseheads from ebay shipping 3.79 to canada.

OT but the solution was presented in this thread.

Well I finally got around to fixing the center post on my Origen Genesis V2 today, I didn't want to tear out my old repair as it was working flawlessly.

So using the screws from Grendel6.5's excellent eBay find and just my Dremel.
I managed to shorten the screw to the proper height, turn down the head so it had a better tolerance in the 510 connector. Drilled a 1.2mm hole through the screw for wire trapping. It turned out quite well if I do say so myself.

The new post:

New coils, reclaimed wicks and vaping like a charm!

Sorry for the poor picture as the HTC like to focus on what it wants to the odd time.

Now back to your regularly scheduled Kayfun discussions!

Have a question for the experts here (or anyone that isn't as inept as myself) , every time i refill i get some leakage out the air holes , what am i doing wrong ?

I am filling through the proper top section and i am not overfilling.

Thanks folks.

I suppose you are sure the JC is fully closed...
And that #38 has flats on the threading...

Other than that, try replacing #16 with 12 x 1.5

 

[cobalt327]

Note- the 12 in "12 x 1.5" above is the O-ring ID. FT sells them under SKU: 1536607. You can also order them from:

• 1.5mm X 12mm Metric Buna-N 70 O-ring (JIS S12.5) [N1.50X012] : The O-Ring Store LLC, We make getting O-Rings easy!
• Metric Buna O-rings 12 x 1.5mm Price for 50 pcs - Orings and More

I wouldn't trust the FT o-rings. I got mine from the 2nd link (Orings and More). They ship fast and shipping is reasonable.

 

[cobalt327]

I have the FT O-rings and I see nothing obviously wrong w/them. For the uber low price I wouldn't expect certified Buna but in a pinch they work.

ETA- FWIW there are quite a few folks on the FT forum who are using them successfully.

YMMV and that's okay.

Buna is synthetic rubber like used in tires, Nitrile is a branded name for buna. The o-rings listed above from FT are described as being silicone.
The metric silicone o-rings from O-rings and More are 75 duro (mostly). I find the China silicone o-rings overly soft. Just saying.

Guyyyssss I have to post something. I'm the dummy who stripped out the threads on my juice control. I FIXED IT... teflon tape yep rated up to 500 degrees, and I figure no direct contact with juice or coil, so that oughta be sufficient. I'm gonna run it thru at least 10 ml at 15 watts first (i never took this tank over 13 honestly) and make sure it doesn't melt discolor etc before I vape it...will update!

 

[ricks]

If I ever strip my juice control threads, I would just epoxy or silicon it together and fill it by taking the tank off. Just my 2 cents.

Actually, I'd just purchase another atty from that 9.95 place I got my spare from...

 

[mamabear15]

Lol rick that's step 2 if this method doesn't work. I figured the only way to find out is to try, and it would be ideal to still be able to open/close! And the link you posted to the 9.95 place was an overstock clearance, according to them...they don't sell for that price normally personally, I won't buy again something that's already broken once...but I will try to fix it! Yep, I'm cheap. Lol

I actually have these O-rings in front of me- all 50 of them. I can attest they are not "overly soft". In fact they feel and look to be exactly the same material as what comes on the Tobeco KFv4 clone from the factory. If I sent two of them to someone and didn't specify which was which, there'd be exactly a 50-50 chance of discerning one from the other.

But if there is anything to take away from this is- again- many people are using the FT O-rings w/o issue. So sometimes a cigar IS just that.

 

[Katya]

Good to know, Cobalt--I never ordered any o-rings from FT, so I have no idea how good or bad they may be...
