    Attack of the (Kayfun v4) Clones!

    WOW! I was so taken with this build that I had to show my wife. She watched the whole build part and then when the camera went "back up" and showed the dude, she said something like "he's not my type, at all". Type or not, this is a really sensible build! Diacetyl is a diketone. Meaning it has...

    To the top of it ? How is your air-control set? Are you getting ANY seeping, as in slightly wetting fingers or mod? Are you getting ANY bona fide leak events, where more than a single kleenex must be used? For me it's much MUCH less likely to leak if I only fill to leave a gap below the...

    FWIW, when I hear of thick residues, with commercial juices, my worry is that 1) they flavor for profit, with no regard for the fact we know nothing of the inhalation toxicity of food flavorings. And it's a matter of amounts. It's one thing to be inhaling 1% acetone, and another to be inhaling...

    Yup #25's a ..... to manhandle. Like wrestling lawyers in an oil spill. And it always wants to go back on cross-threaded. How do you guys prevent over-filling? Is pulling out when the liquid reaches the top ledge of #26 practical? Or the bottom of #32? I saw a picture of a V4 on a French...

    If you referred to the part by its number - one of the wonders of the V4 - we could properly commiserate. ;-) As to the washing, what rinse would it be rinseth werewith ? Glycerin? If we use water it has to be dried. If we use ethanol, it must be evaporated. So why not use the juice that it...

    Attack of the (Kayfun v4) Clones!

    Maybe I was lucky, but I built my Kraken clone before I built my first KF V4, while I was new to the whole rebuildable thing. The rolled SS 400 mesh wicks were about 2 mm in diameter, so there was a little "play" in the 2.5 mm deck holes (which BTW are threaded on my Klaken crone). The coils...

    Of course it depends what kind of vaper you are, since personally I don't vape above 30 watts, I don't care about such small differences in conductivity. I don't know if the effect of brass is significant on the 510 positive pin itself, and maybe just solid SS would be easier to make? But IMHO...

    Now both the silver and the black are vaping great. And so is my older son's silver. I can't be sure what I did differently on the one dry build, but I think that I had packed the wick too tight in the wells. The silver unit has a 5/64" drill bit wind 28 G 1.4Ohms, and the black a 7/64" 28 G...

    Attack of the (Kayfun v4) Clones!

    After my "skinny wick" problem, I got another build that's not quite wicking well on my new black Tobeco. Granted, the deck surface isn't quite as cleanly machined as on the plain stainless one, but nothing that would explain it. Let's see how the next build goes. There are SO many variables...

    No wonder it won't play. You need some finger-holes. Don't be shy. Just drill right across the body, battery and all ;-)

    Dry hit? Wicking problem? I thought ... They're always saying "less is better". Not always so. Too skinny a wick here. So we got glycerin overheating. At 280 °C VG breaks down to Acrolein, foul & toxic. Doh.

    Glad I waited for the black FourNines clone for the black Tobeco KF V4. It's a stunning and very compact rig. In fact I'm puzzled at how much smaller the FourNines is than any other mod. Same battery, same atty, much shorter !? Very small flush magnetic switch, pinless 510 head. Smart...

    Attack of the (Kayfun v4) Clones!

    Yeah that anticloning re: the logos shouldn't go too far! Those Germans design a mean machine. And I'd rather fly in a Boeing 747 than a Poing. Got an allegedly Tobeco spare parts kit. $15 shipped. Sorry assed pinch of penny parts in a baggie. The #16 was no better than the stock ones. Nice to...

    Attack of the (Kayfun v4) Clones!

    Yass! And the Lemo looks good sort of half tone. Thinking of mixing & matching parts from a black and a SS. That just MIGHT require buying more ... I'm sitting here eating lunch and running out of liquid. I just realized I went through most of a KF V4 tank - what is that, 3 ml? AND most of a...

    There was a lot of interesting material about coil effects when the Genesis atomizer was first proposed, the guy who invented it was tabulating vapor droplet size with different tightness of coil over weave of mesh, and resulting throat hit vs flavor. I've forgotten it all now, worth looking up...

    Black Vampire Tobeco KF V4 is waiting, lovely & sepulchral in her box. Those vapeomg guys in LasVegas are fast. After all the ritual washing, alcohol soak, threads & toothpaste, she seems to be all there. I coiled her up, 28g 7/64" 1.4 ohm, but I don't want to offend the Tobeco gods, so I'm...

    "Above"? Well, no, there are 4 independent parts below the glass/metal tank ring that can all "spin" for different purposes. You need to do some more reading, Youtubing or Googling before launching, or you could strip/damage your unit (not to speak of your remaining coil jig parts) ;-) This...

    I may sound like a brok-brok-brok-broken record, but why are y'all bothering ordering from China, when local US vendors consolidate enough qty to offer about the same price on e-bay with shipping included, no customs anxiety and delivery within a week? And even in cases where they add a...

    1) Removing the air adjust screw B13 on a Tobeco seems to have brought on leaking. Put it back in and it's fine again. Is this a known thing? 2) @Marc411 can you explain specifically in what you now prefer the EHPro - now that the various issues have been corrected by your vendor ? I see...

    Attack of the (Kayfun v4) Clones!

    I'm running my BigDripper clone with a single 1.5 ohm coil, and I can get great flavor and clouds with it even on my old ProVari 1!. I run it hotter with mechanical mods, but it's all good. It's probably true that you'll want more power in time, but there's no reason to wind sub-ohm coils...
