    Default Ithaka: best build?

    Hey!

    Since there's a huge Ithaka thread with all the information that you just can't find ^^, I figured I'd ask in a seperate post.

    Whats your favorite build?
    I got mine yesterday, rebuilt it twice, but so far I wasn't able to achieve the performance of a ProTank, so I'm guessing I'm doing something wrong.

    First built was a simple X-shaped dual coil at around .9ohms, using 2mm Ecowool and 0.2mm Kanthal D/0.2mm nickel (guess that's 32g - weird system). Had only around 3 pretty far spread wraps, tasted like nothingnothingnothingBURNT. That was my first build ever.
    Rebuilt it with the same stuff, only now I used more res wire and ended up with 1.4amps. I ended up with 5-6 coils each. I also put an uncoiled string of ecowool in between the two coils - I ended up cutting most of the excess wool while screwing the thing together.
    It's a bit better now, but I ended up with less vapor and a bit of a weird taste, but that might be the coils needing some more burning in...
    I also have some 3mm Ecowool, and I'd try that next. Possibly not in an X-shape, but I dont think that's my main problem here..

    Any ideas? Pictures/Vids would be awesome, I think I just suck at building coils.
    Also, what's the deal with micro coils? Would that work on an Ithaka? Why use cotton instead of seperated silica wicks?

    Thanks

    My First guess, after me and the guys experienced with Ekowool, is just it doesn't wick fast enough. I say experiment with silica, or if all you have is Ekowool, use the Krinkle method, where the wick is only on top of ceramic without coming inside the channels. 2mm might have blocked the channels and the delivery of juice. With duals you need juice flowing more freely.

    I would highly recommend 2,5mm Wolf Silika: https://www.vapor-freak.de/zubehoer/...-Silikatschnur

    It wicks like crazy and has a high resistance to heat.

    I started with simple crossed wick single coil build. This helped me get my head around all the adjustment capabilities the Ithaka provides. I have just now moved up to a double coil and getting it dialed in was easy. One thing I have learned is that the adjustable air feed can help a lot. Allowing more air though the coil keeps it cooler. With my current double coil setup I am opening up the air control when the battery is fresh and then slowly closing it as the voltage drops. Think of it as manual thermal management

    I keep it simple with a single coil now because of some issues I'm having but back before this started, my favorite and best Ithaka build was a double dual coil in an X. I forget the lengths but I think I did 2 wires that both had 2 parallell, 2.5" pieces of R wire in them. Wrapped them around 2 wicks, installed in an X, and it was great; resistance was around .9 and it lasted for weeks.

    My personal experience (as limited as it may be) is to have dual coils parallel, .5 ribbon Kanthal and 32Ga Nickel NR. 1.5 Ohm each (.75 Ohms total) wrapped around cotton yarn I got from Wally World. http://www.walmart.com/ip/Sugar-n-Cr...Cones/24629135 Trim slightly higher than the base o-ring so none of the "fluff" gets caught in your seal.

    Cotton wicks better than any of the silica or ekowool I have. The drawback is that you cant "dry burn" with the wicks in place. The solution was to configure the coils in parallel and treat them similar to Microcoils in that you can just leave the coils in, remove the cotton wick, dry burn without a wick in, and thread a new wick when the coils are clean.

    I typically use sweet fruity flavors so with traditional coils I needed to replace or dry burn every 3-4 tanks. The ribbon wire doesn't seem to gunk up as fast as traditional resistance wire, however some people have reported that ribbon wire has a sharper TH. Bishop calls them "Razer Edge Coils" (although my construction varies slightly) and they seem to produce a much hotter vape. (not warmer, HOTTER, as in you have to aim the airflow in your mouth or you will feel like you are burning the inside of your mouth. )

    So far I am on about 3 weeks with the same coils and 2 dry burns compared to 2 dry burns a week with a traditional setup. After dry burns, taste is off a little bit for about 1/4 tank then cleans right up. YMMV.

    So far for me: dual coils, 32g Kanthal 30g Nickel, .6-.7ohm with cotton hemp yarn wicks or silica (still need to try hemp twine)

    Currently vaping: JustGG #0240 with GG Ithaka

    The best build I've come up with for the Ithaka requires just a few things to pay attention to. First off if I may suggest forget ecowool, cotton etc (just MHO) use 2mm silica wick from Esmoke Guru or COV, best whicking I've tested (I know many of you may disagree but it's my personal opinion). Make two coils of about 1.6-1.7 ohms and make them of equal length. I use Nickel .20 for non-res and Nickel Chrome .20 for resistance wire.
    It's important to understand that dual coils require very good juice feeding because they run much hotter than any single coil. The trick to good juice feeding is not only the correct use of Ithaka's mouthpiece juice control. The coils MUST not be wound tight around the silica because this causes restricted juice feeding. I use a single piece of 2mm silica in each channel which provides for ample room in the silica channels of the ceramic housing for good juice feed. To ensure I don't wrap my coils tight I use a needle with the silica when I wrap my coils and apply only enough pressure to wrap the wire around the silica. Once wrapped I remove the needle and the result is a wrapped coil that doesn't restrict juice flow. Depending on the viscosity of your juice you could increase the thickness of your silica. I use 80% VG and 20% PG so my juice is very think and I need good flow in the channels hence I use 2mm silica. If you use thinner juice with high PG content base you could use 3mm silica.
    Once my coils are installed in the ceramic housing in the X configuration I space them out so they sit nice and equally in the center. I then prime them and the silica with juice before installing the mouthpiece.
    My juice requires the mouthpiece juice control at least 1/3 rd open
    Hope this helps
    Happy vaping

    PS As anything Ithaka requires some trial and error to find what works for you best but it's an incredible atty which once mastered simply cannot be matched.

    Capt Steve with that configuration do you use the basic feed too or close it off?

    I personally keep it off and just open the mouthpiece

    CaptSteve's build is very similar to mine although I use about 2.5mm wick because I vape 50/50 juice. I agree with all of his statements about the coil don't wrap to tight and make sure you don't put to much wick in the channels.
