  5. Kayfun Replacement O-rings and Screws!

    So I know I originally intended to only blog about random builds that I've figuring out, but it just dawned on me that there are SO many important information out there in ECF, except that they are buried in MASSIVE threads. so I figured I'm gonna start compiling and categorizing these information; mostly just because it'll be useful for my own reference, and well, it would turn out to be useful for some folks.

    First thing! If anyone is looking for:
    1) a source of replacement o-rings
    2) replacement deck screws with flat bottoms (many clones have crappy post screws that are rounded at the bottom, making it real hard to capture your leads)

    and like me, refuse to pay the ridiculous mark up for normally dirt-cheap and accessible parts, you're in luck.

    O RINGS:

    (Btw, the information in this post is courtesy of the very kind ECF-er, Akdare)

    1) Fill screw oring (the super tiny ones): 2mm inner diameter x 1mm wide
    2) Chimney (sits in the top cap, where the top chimney section slides through): 5mm inner diameter x 1.5 mm wide
    3) Base and other sections: 18mm inner diameter x 1mm wide

    1) Fill Screw oring:
    2) Chimney oring:
    3) Base and other sections orings:


    1) What: Those tiny screws for capturing the leads on the deck. Critical dimension: M1.6x0.35mm

    1) (If this is no longer listed, look for the seller Zoro Tools, and find the Cheese A2 SS 3mm Slotted screws. I've found the 3mm to be absolutely perfect)

    2) (this is a philips head instead of slotted)

    There are definitely other sources, but these are the 2 places I've personally bought from and tested them. The main thing about these screws is the fact that the bottom of the screw head is flat, allowing for super easy captures.

    2) What: Fill hole screws! (information courtesy of Paul.K)
    a. Kayfun Lite: M2.5 Countersunk, length = 4mm
    b. KFL+ : M2.5 Pan head, length = 4mm
    b2. From MaxUT: For the KFL+, apparently the M2.5 x 0.45 x 5 screw also works (Havent verified this myself)

    Where: No clue for a. and b. I personally haven't bought these replacements before so i can't help. If you know of a source, please let me know!

    For b2, it can be found here:

    Thanks Kiwi!
  6. Is Everything We Know About Nicotine Wrong?

    Dr. Kelly Neff
    1 October, 2014 at 18:06

    Because of its size, more than 10000 characters, I am putting a link in for the whole article on ECF. It created thoughts and that is what reading is all about.

    I do thank the original poster for finding the article.
  7. Yes, there are that many flavors containing diacetyl...and there are just as many that contain acetyl proprionyl & acetoin (other "butter" flavors), especially since diacetyl has been limited or removed from many 'vaping flavors'. Acetyl proprionyl has been shown to be just as dangerous as diacetyl. Acetoin is bad news, too (especially when combined with certain chemicals).

    Most don't seem to realize that it takes several hundred individual chemicals to create just one 'simple' flavor (like strawberry). Read more about 'flavor chemistry' here (a great overview, including info on 'natural flavors'): Food Labs Use An Average of 2000 Chemicals To Create 500 'Natural Flavors' You Would Never Suspect Are Artificial

    When we make a juice involving 4-5 flavors, we're actually chemists mixing THOUSANDS of (unknown mostly) chemicals. For example, when we mix coffee + chocolate + cream + other + vg + pg + nic...this is not the mere handful chemicals most imagine (vs the thousands found in burning tobacco plus the hundreds possible additives). An e-juice containing several compound flavors is also THOUSANDS of chemicals (plus all the chemicals that are formed by the chemical interactions & the heat).

    Of course, every natural plant & food also contains several hundred chemicals (even thousands), but there's a major difference between 'white chemical powder isolates & synthetics' and those found in natural foods where the levels, synergy & interactions have proven to be safe for ingestion throughout time.

    When health is a concern, we suggest doing everything possible to lessen the level of chemicals. Knowledge is the key. Learn the tips n' tricks to keep the 'flavors' to a minimum:

    --use VG diluted with distilled water & saline solution rather than PG (or minimize the PG). PG is more dehydrating and has a musty flavor that can only be covered by using more chemicals. .9% sterile saline solution seriously ENHANCES flavors (which equals less chemicals needed), and it's very safe, hydrating & soothing to vape. Some say distilled water also enhances flavor a bit.

    --minimize or eliminate "additives" that are known to diminish flavor in a juice -- those are EM, vinegar, lemon juice/citric acid, and sucralose. We've been DIYing for almost a year, and have only used sucralose once or twice; we've used EM very sparingly. The one time we used more than a few drops of sucralose, 3-4 days later the juice was 'dead' (it really had lost 30-50% of it's flavor. Look at recipes - anytime one sees 1-3% sweetener or EM, invariably one sees high flavor percentages. One of us has a major sweet tooth - yet we've never needed added sweetener.

    --Vape Wizard, Magic Mask (FA) and Smooth (TFA) are chemical blends designed to 'take off rough edges' and smooth/enhance vapor. They do this not by changing or adding flavor/chemicals, but by a designer chemical cocktail that actually alters the actions of our taste buds/receptors temporarily. Like diacetyl, these chemicals are "approved as safe" for eating. Who knows what they'll alter 'temporarily' when mainlined into our bloodstream via inhalation.

    Back to diacetyl/similar; from here: CDC - NIOSH Update - Diacetyl and 2,3-pentanedione: NIOSH Seeks Comment On Draft Criteria Document

    For Diacetyl, a recommended exposure limit (REL) of 5 parts per billion (ppb) as an eight-hour, time-weighted average, (TWA) during a 40-hour work week. To further protect against effects of short-term exposures, NIOSH recommends in the draft document a short-term exposure limit (STEL) for diacetyl of 25 ppb for a 15-minute time period.

    How much is 5 - 25 parts per billion? It's 0000005% - 0000025%

    What's the percentage of diacetyl in that 100mls of juice? .00012%

    Using this "ppb calculator" Parts Per Billion Conversion Chart (Fractions and Percent Converter, Percentages And Parts), we find one must enter 1200 ppb to equal .00012%

    So, vaping that particular flavoring at 2% means we'd be vaping 1200 parts per billion, when the 'safe zone' for short term exposure/inhalation is 25 parts per billion.

    Yes, we DO have reason to avoid these chemicals. Even if they're 50 or 75% less than the example, we'd still be in the 300-600 ppb zone. Of course, the raspberry flavor starts at .00009% diacetyl, and that works out to WAY less than 1ppb (around .012 ppb, if I calculated quickly correctly).

  8. Why Is The FDA Shielding Smokers From The Good News About E-Cigarettes?


    By Gilbert Ross, M.D.

    Any clear-thinking health professional would agree that cigarette smoking is without question the most devastating and preventable public health risk that we need to address in this country. And now, four-plus years after the Food and Drug Administration (FDA) was given legal authority over tobacco products, the regulatory agency faces arguably its most important public health decision in its history. The time has come to confront their responsibility to smokers trying to quit and their families.

    The worldwide death-toll of cigarette smoking is reliably predicted to hit one billion this century. Despite this depressing fact, the measures implemented by the FDA thus far, ostensibly to reduce the toll of smoking, have been almost entirely lip service, without making any real impact. A relatively new method of helping addicted smokers quit has been adopted by millions of smokers – many of whom are now ex-smokers — over the past few years. I refer of course to electronic cigarettes (e-cigarettes). Concurrent with the dramatic spike in sales of this device comes word of historic declines in the sale of real cigarettes.

    E-cigarettes work by delivering a potent “hit” of nicotine in water vapor, with flavorings and propellants of no significant health concerns — neither to the “vaper” (as they call themselves), nor to bystanders. Most of them resemble cigarettes — which is both their blessing, and their curse.

    Astoundingly, this nascent public-health miracle has been met with something between derision and hysteria by anti-tobacco groups worldwide: globally, the WHO, health-oriented NGOs, the British regulator MHRA, and many nations are sparing no effort to discourage smokers from trying them, employing misleading (even false) alerts and dire website warnings, phony surveys, and exaggerated concerns about youth being led astray. Unfortunately, and embarrassingly for science-based public health policy, our FDA and CDC have been willingly complicit in this widespread disinformation campaign. Meanwhile they purposely ignore studies that indicate the benefit of e-cigarettes for helping smokers quit. I ask, “How could this be?”

    The possible explanations are not pretty: willful ignorance, dogma based on experiences garnered in the 20th century, or greed.

    I accuse those responsible for impeding truthful communication about the real risks of e-cigarettes of collaborating in a “cigarette-protection campaign,” whose effects will be to discourage smokers from quitting, leading to more dead smokers. Consider this: those who stand in the way of acceptance of e-cigarettes are acting from motivations that are far removed from public health. The nonprofit groups in the forefront of anti-e-cigarette activism are also heavily funded by pharmaceutical companies in the business of selling near-useless cessation drugs — a fact which they conveniently neglect to disclose. If tobacco companies carried on the same way, they would be hauled into court by the FDA in a heartbeat. Meanwhile, the net result of the official campaigns: cigarette markets protected, worthless cessation aids promoted. Who profits? Not addicted smokers.

    Despite the pervasive anti-smoking campaigns, a handful of marginally successful cessation drugs and the “denormalization” measures, the addictive drumbeat goes on. In our country alone, cigarettes exact an annual sacrifice of about 450,000 prematurely dead. Another 8 1/2 million people and their families suffer lingering ills thanks to smoking. And still, near twenty percent of our population continues to smoke, with little change over the century’s first decade.

    Quitting cigarettes is extraordinarily difficult — most smokers want to quit, but of the millions who try each year, less than one in ten succeed for long. This abysmal result is improved only minimally by the currently available FDA-approved therapies. Despite these undeniable facts, the officials at our CDC and the FDA continue to tell smokers to stick with the “approved” products, and warn them against e-cigarettes — based on hypothetical fears, while perversely ignoring the body count.

    Time is running out for the FDA. The law requires them to decide how to regulate novel tobacco products (a 2011 Federal court ruled that e-cigarettes are tobacco products, thanks to the nicotine they deliver). If the regulators flout all the science and squeeze e-cigarettes into the same framework as cigarettes, millions of ex-smokers will revert to toxic deadly cigarettes, or they’ll find them on the Internet (the black market) — and many more will die with a cigarette in hand. One thing is certain: this genie will not go gently back into the bottle.

    But if the FDA’s Zeller decides to interpret the law flexibly — there are provisions in the law to allow it — and exempt e-cigarettes from such stringent regulation, while enforcing sound manufacturing practices, valid product labeling and a ban on sales to minors, a revolution in public health may transpire. Listen, to everyone’s surprise, the European parliament did just that! Those of us devoted to public health now have reason to hope that our FDA will hear the lesson from the EU, and flout the hysterics and rent-seekers whose messages would lead to more needless smoking-related death.

  9. Results of Incorrect Use

    As we can see, incorrect use doesn't work and has issues: little or no nicotine will be delivered; coughing or irritation to the throat or lungs may result. An e-cigarette (especially a mini ecig) is not used like a tobacco cigarette for multiple reasons. Tobacco smoke contains materials that are engineered to have an anaesthetic effect on the throat and lungs, but e-cigarette mist does not have these compounds.

    There are probably more clinical studies carried out and published where the researchers didn't know how to use an ecig than studies performed correctly with advice from an expert. We can easily see this in results that include reports such as '"zero or little nicotine was delivered" or "the lungs were affected". It is a little worrying to see such results since it brings into question the results of other studies: if clinical researchers are not competent to obtain correct results (by asking for advice from experts), could other results they obtain also be wildly inaccurate?

    The sub-optimal results many researchers have obtained resulted from the assumption that EVs and cigarettes work in a similar way and are used in a similar way. Don't make the same mistake or you will also get poor results.

    They are different
    Always use your ecig in a different way to a cigarette (apart from them both going in the mouth). If you find yourself doing something - anything - the same, it's probably wrong and almost certainly suboptimal.

    Expert users
    Experienced users, using a variety of different hardware and refills, use different approaches. Some use a direct lung inhale, sometimes where this is combined with a large air hole in an RBA. Because there is no one-size-fits-all solution in vaping, there are a multitude of different inhalation techniques. Read this thread for a description of some of them:

    Lung Inhale vs Mouth Inhale
    The posts in that thread are a clear indication that smokers, and vapers, use a wide variety of inhalation methods. The advice above is designed to allow newcomers with less than optimal set-ups to get the best results.

    Definitely to be avoided J
    Try not to apply a lighter to the end of your e-cigarette.
    Don't try to flick ash off the end, you'll look stupid.
    Do not throw your ecig out of the car window after finishing with it.

    General Notes
    This information is derived from multiple expert sources including clinical trials and lab tests that we know were executed correctly, such as by Dr Laugesen [2]; and expert vapers' experiences with multiple hardware and liquid types.

    There is a wide variation between the effects of e-cigarette use for different individuals, and in some cases this has been demonstrated first here at ECF. For example, we can show that there is a factor 10 difference in individual tolerance to nicotine: some cannot over-vape 6mg (0.6%) strength liquid; some must use 60mg (6%) strength in order to avoid relapse to smoking. Because of this it is impossible to state what any given individual's response to a specific item of hardware, or e-liquid type or strength - and especially a combination of the two - will be. The differing effects on individuals are multiplied by equipment variations and then multiplied again by refill variants. Therefore, only the individual's own experience is valid, since the variables are impossible to calculate. There is no one-size-fits-all in vaping.

    Because of this, no hard and fast rules can be stated. The above advice is a general guide, and best used as a starting point for individual testing and trial. It is specifically written for beginners and those not familiar with optimal e-cigarette use; it is especially applicable to mini ecig use. Experts find their own way of utilizing their hardware-refill combo. With larger and more powerful equipment and/or strong refills, the inhalation method is less critical for deriving full benefit with minimum negatives.

  10. Inhaling Notes

    E-Cigarette vapor is not drawn directly into the lungs, as many smokers do with a tobacco cigarette. The lungs do not 'suck' on the ecig; a direct inhale is not used. Instead, the vapor is first drawn into the mouth, using the cheeks to create a vacuum, then inhaled if desired.

    The vapor doesn't have to be inhaled though, and an ecig can be used like a cigar, with the vapor only taken into the mouth. Nicotine will still be delivered as the water-based vapor is absorbed in the mouth (and nose).

    First the vapor is drawn into the mouth (not the lungs), then held there for a second or two. Then, it can be inhaled if desired. The vapor is then expelled through the mouth or nose.

    The vapor is drawn very slowly and gently into the mouth. A hard pull, as is normal with a cigarette, cannot be used since:

    - The heater coil doesn't work properly unless air is drawn across it gently for several seconds. There will be little or no nicotine in the vapor if a short hard pull is used.

    - A hard draw may pull liquid into the mouth.

    E-Cigarette vapor is a water-based mist and not smoke. This has two main consequences:

    - The droplet size in vapor is much larger than the particles in smoke, and therefore it does not penetrate as deeply into the lungs. Vapor aerosol is ten times the particulate size in smoke (10 microns vs 1 micron). Vapor cannot go anywhere near as deep, and this means that nicotine is not available so easily from the lungs, and is obtained more slowly.

    - It is likely that just as much nicotine is absorbed by the mucous membranes in the mouth and nose as within the lungs. In fact for maximum nicotine delivery, all three need to be employed: mouth, lungs, nose - otherwise all the nicotine in the vapor will not be extracted.

    Indeed it is not necessary to inhale, when using an e-cigarette, to obtain nicotine: holding the vapor in the mouth will suffice for some people (especially with high-strength liquid), and expelling some through the nose as well, after a very shallow inhale, will add to the nic delivery. Persons with serious lung diseases caused by smoking, such as emphysema, can take advantage of this - since inhaling anything further, even mist, is absolutely not advised.

    Nicotine delivery via cigarette smoke is unusually rapid - it reaches the brain in around 8 seconds, which is at least three times faster than injecting nicotine, which takes up to 30 seconds to reach the brain. This is part of the grip cigarettes have, since this ultra-fast delivery becomes associated with the act of smoking.

    Nevertheless, a properly set up e-cigarette, with a sufficiently strong liquid for the equipment and user, used correctly after advice from an expert, will deliver nicotine within 30 seconds. After a period of adapting to the new delivery method, this has proven acceptable to smokers switching to the ecig. Experienced vapers learn how to optimize this extraction process and that includes the speed of delivery.

    6. Lastly, an 'inhale' on an ecig (which as we have seen above is nothing of the sort, it's more of a 'suck') is much, much longer than with a cigarette. On average, there is only somewhere between 10% and 50% of the nicotine in ecig vapor compared to cigarette smoke, so more vapor needs to be taken in, and for a longer time session - probably about 12 minutes as against the 5 minutes a cigarette lasts. Also, the atomizer simply doesn't work if a 2-second inhale is used, since for at least the first second it is warming up and does absolutely nothing.

    With a small ecig we draw into the mouth for between 4 seconds and 8 seconds (yes, 8 seconds), depending on how efficient the device is, how strong the liquid refill is, and how expert the user is; the average draw length is 4 or 5 seconds. This would be used with a mini ecig, for example. As you can see, a slow and gentle 'suck' of 5 seconds bears no relation at all to the sharp, hard lung inhale of 1 or 2 seconds often used with a cigarette.

    With a larger and more efficient ecig we might use a 3 or 4 second draw. We don't use a direct lung inhale or a 2-second draw with small ecigs, except by personal preference, for occasional variation. Neither works: a lung inhale doesn't get enough nicotine and causes soreness and coughing, and a 2-second cigarette-style draw is basically a placebo operation as the atomizer won't be doing much.

    Please note that expert users, using larger and more powerful hardware, use a variety of inhalation methods.

  11. New Vaper Notes

    Virtually all newcomers to electronic cigarettes are smokers [1], so it is natural for them to try to use an e-cigarette in the same way as a tobacco cigarette, especially as the first model chosen may be a replica of a cigarette.

    Unfortunately this doesn't work well, as the two things may look similar but are functionally very different. One is a paper tube where the smoke from burning chopped-up vegetable matter is inhaled; the other is a steel tube producing a water-based vapor from a liquid that is vaporized by a battery and heater element - essentially, a low-temperature steam. One contains tobacco that is set on fire at high temperature; the other has no tobacco and generates mist using a battery. There aren't really any valid comparisons between the two.

    The most accurate term for an 'e-cigarette' is probably an EV, electronic (or electric) vaporiser. The vast majority of EVs do not look anything like a cigarette, although the sales figures are opposite to this: minis that look like cigarettes do have huge sales volume as they are by far the most popular with smokers trying out the concept. In addition there is no functional similarity between an EV and a tobacco cigarette. It is probably best to think of the terms 'electronic cigarette' and 'e-cigarette' as marketing terms since most EVs don't look anything like a cigarette and none work anything like a cigarette. However, hardly any smokers would switch if the name EV or something similar like PV or vaporiser was used exclusively - so 'e-cigarette' works very well indeed to get smokers interested. This tends to obscure the fact that the two things are different and are used differently. Mini ecigs, especially, need a different technique in order to derive maximum benefit with minimum problems.

    If an ecig is used like a cigarette, it doesn't work, and there might be other issues too, such as a sore throat or lungs. This is generally applicable to a new ecig user with a mini ecig although it may not apply in other circumstances (expert users, with better hardware, make their own rules - this info is mainly for newcomers using minis).

    An ecig doesn't contain any tobacco, there is no combustion, there is no ignition, there is no smoke; the process involves generation of low-temperature 'steam' from within a saturated atmosphere in an electrical device - not the burning of dry plant material. Multiple clinical trials have demonstrated that if an ecig is used in the same way as a tobacco cigarette, by beginners using a mini ecig, either zero or very little nicotine can be measured in the user's bloodstream.

    So now that we know it must be used differently, the question is: how? The short answer is that the only similarity is that both are placed in the mouth. After that, everything else is different, when talking specifically about optimal use for new users using low-power hardware.
  12. Just to start getting back into my vaping hobby. I am soon to return from AFG and will have room to play with my stuff. One thing that I want to start is rebuilding my own.

    Here in AFG, my space is rather limited for having a hobby. Anyway, I just ordered new juices so that they will be there when I get back.

    I wish all happy vaping!

  13. Am overseas with the military. Seems rare to get on. Happy vaping!
  14. This is a link to an editorial response that gives the clarifying facts. A good read
  15. Just a good one to watch.
