A Step by Step Pictorial - how to wick the Aromamizer RDTAs and avoid leaking issues

The most common issue on vaping forums concerns leaking and this is almost always down to incorrect wicking. This pictorial is relevant to all the Aromamizer RDTAs that use the Velocity style 2-post deck ... if you get the wicking right you should encounter zero dry hits and zero leaking, even when you leave the atty on its side.

I've chosen to build a 23mm Supreme deck, with a spaced coil build of 3.2mm ID, so that the best view is given of the wicking.

The wicking material I've is Muji organic cotton ... the outer layers are removed and the fluffy core of the pad is cut into strips

The chosen strip is then rolled gently (don't compact the fibres) between thumb and forefinger to get a nice even sausage shape, then pinched hard at one end so that it feeds easily through the coil. 

The tension on the wick through the coil can best be described as slightly resistant; not stuffed in so hard that it must be tugged, and not too loose either. The cotton will swell once juiced up and we mustn't choke the flow of juice.

Use the outside of the base cap as a guide for trimming the wick tails to length. The sharper your snips the better as you want the wick tails to remain nice and fluffy.

Use your tweezers or a prodder (for example, an unwound paper clip in this instance) to gently fold the wick tail onto the deck. No pressure is applied here, no compacting, the wick tails should simply rest over the juice hole.

Repeat the step with the other tail. Your relaxed wick tails should meet in the middle or even slightly overlap. We want to completely cover the deck with our wicking and certainly never leave a juice hole even partly exposed.

Once both tails are on the deck, use your prodder to open the space beneath the coil so that the airflow is not obstructed.

Wick both coils in exactly the same way. 

Now you're ready to juice up.

Once juiced, use the prodder to gently "dress the wicks", to get all the cotton fibres saturated and shaped. Ensure that all the wicking is within the deck because you don't want your wick tails compressed against the side of the chamber once the deck is installed ... this can lead to juice running off the wicks towards the airhole. 

Now that both wicks are juiced up and shaped, it's time to install the deck into your Aromamizer and enjoy the vape.

In summary then ... a. think fluffy clouds of wick, nicely relaxed and never compacted ... b. ensure the deck is covered by your wick tails, don't leave any of the deck exposed, especially not the juice holes ... c. keep all the wicking within the circumference of the deck, don't allow the wicks to be squeezed once installed or the juice will be forced out onto the chamber walls. 


The next pictorial shows how to wick vertical coils, these are stainless claptons of 3.0mm ID. Normally, I use slightly more wicking with claptons than a straight wire, so expect a little more resistance through the coil.

Prepare the wicks in exactly the same way as in the above post for horizontal coils. Insert the wick from the top down and pull the wicking through using tweezers until you have cleared at least the section which was squeezed. Then trim flush with the outside of the base cap.

Fluff up the tails until you have a lovely cloud of fibres.

Using tweezers, pull the top tail of the wick up slightly until the bottom tail is resting on the lip of the deck, then gently push your fluffy cloud onto the deck.The tail should be just touching the deck and juice holes at this point.

Now trim the top tail flush with the top of the posts, and pull down the bottom wick until the top tail is flush with the top wrap of your coil ... I have seen this described as the buzzsaw trim.

Pulling the wick down just a millimeter or two will see your bottom tail now resting fully on the deck and giving complete coverage ... no deck should be visible, just your wick tail. This is important!

Repeat the process for the other coil, not forgetting the important step of fluffing out that bottom wick tail.

Now juice her up and give your build a test fire. Watch as the top of your wicks resaturate after firing each time.

Time to install the deck into the chamber.

One potential problem which I often see is that the top tails are left too long, high above the posts. This can cause problems ... firstly, the airflow to the chimney maybe obstructed. Secondly, the top tails can contact the top of the chamber and wick off the condensation. Often this causes the top tails to darken, then the coils themselves can darken early and give a bade taste. What you are vaping there is juice that has already been vaporized once or twice. so my advice is keep the top tail no higher than the top of the posts.
