Merlin by Augvape and Roxy

[LilWhiteClouder]

I have to rebuild my Merlin today my notch coil I've had for over a week is starting to taste like junk. I was thinking about trying a hand wrapped dual coil. How well does that work? Also Does it fit with the air flow resistor in?

Same happened to me with the notch coil provided. after about a week it tasted terrible and the build up was too much for me to use it again. Been using hand builts ever since with pleasing results. My last coil build was on there for a little less than a month (with a few rewicks of course).
I have yet to use the AF restrictor, so I am not sure if it sticks out above the normal air intake. And I really don't know how much headroom is at the top there above the top coil. But, if you use smaller IDs (~2mm) you shouldn't have a problem sticking dualies in there.
The top coil (below) is 3.5mm and the bottom is 2mm. I wanted to make sure the airflow made it to the top coil. I think it will flow nicely around the bottom coil, though, no matter if they are both the same size.

I just tore mine down to wash it for some new juice/rayon and try a pre-coiled hive wire I have that is lower ohms than the clapton I have been using. Fitting a dual coil setup like that looks a bit tedious. You have more patience than I do that's for sure.

The hardest part was getting them to fire evenly. I had to remove a wrap from the top coil after the first attempt. I swear it vapes like an rda now.

I keep mine totally covered.

Thanks, that's what makes more sense to me. I've heard that you can't use too much cotton, so I'll take another look at what I did. It'll be wick and o-rings first. If that doesn't work I'll have to follow the reseating instructions below. argh!

To reseat the deck:

1. Place the merlin deck upside down in a 13/16" spark plug socket or similar. This should be supporting the deck by the juice flow ring.

2. Place an additional socket over the 510 connector. This would be any size large enough to not touch the 510 connector

3. Tap the top socket several times with a hammer. Try to tap it dead center so any pressure will be evenly distributed across the entire deck.

If you are experiencing leaks, it's more than likely due to wicking. Make sure your wicks completely cover the tops of the juice wells and that it is not touching the portion of the deck that contains the air hole.

Thanks a bunch. After reading through this twice, I realized it's not as hard as I thought and I have socket sets, possibly even two spark plug sockets. Of course, I'll make sure it's not the wicking or worn out o-rings first. Thanks again, you guys are the best!

The few RTA's I did before this all needed wick up above the bottom of the juice wells so I had leaking issues with this at first when I wicked it like I did others. Once I watched a few youtube videos and asked/read in this thread I realized I needed to use more wick all the way to the bottom of the wells and no major issues since then except when I forgot to close the juice flow control before refilling.

Where is it leaking from? The bottom of the glass tank, or the air slots. If it's not the way the wick is setup, It could be that the o rings are getting worn out. You said it was used. If you don't have spare o rings. I made a thread a long time ago on here and it works for me.

If the o rings look worn like they are too big and don't have the elasticity they should. Take off all the o rings and drop them in boiling water for like 5 to 10 minutes. Then move them into ice cold water for another 5 minutes dry them and use them. This should allow the rubber to expand and then contract so that they shrink back to the normal size.

The seller sent a pack of o-rings and a spare glass tank. I'll have to check if all the o-rings are present, but that is great advice you gave me, just in case. I was hoping it was leaking from the glass tank, then I could just change out the ring but no, out of the AFC holes. I suppose it wouldn't hurt to put fresh o-rings on, anyway. I'll go over everything again and see what I come up with. Thanks so much, you guys covered all the bases for me

I used to do the o ring trick on my kayfun all the time. Had it for like 2 years and never replaced an o ring.

But if it's leaking out of the AFC then there are still a few things it could be. It could be getting too much juice in the wick and leaking into the air intake. But if there is a not sealed o ring it would cause air to leak into the tank causing the juice to flow into the deck and ultimately causing it to flood. The o rings have to keep the juice in and the air out.

When you build it and first fill it after you take a couple draws, do you notice air bubbles rising from the Juice holes even when you are not drawing on it? If so It's probably an o ring. If not then it's probably over saturated wick.

ThanksI did push the tails down but maybe there's not enough coverage at the top of the JFC holes. Just to be clear, when you refer to juice wells on the Merlin are you referring to the two oval shaped wells on the deck, right below the JFC holes?

Fluff out your wicks so that the tops of the open wells on the deck are totally covered.

Hmm, I'll have to pay attention to that detail. All I know is that when I first filled and vaped it, I was blown away. Loved it. After taking several pulls with no incident, I put it aside. I saw it hemorrhaging several minutes later.

Yes, thx, I did do that.

Yes, it the spot where the wick is supposed to site like in this picture.

Here are the 2 videos I watched:

@muth, what is your juice ratio for pg/vg?

Okay, I use cotton. So just do the same thing with cotton? Someone said make sure the oval wells are completely covered. My coil is a fatty and so is my wick. So, is it okay if some of the tails are spread out beyond the top of the wells? I've made sure that the air hole is not obstructed by the wick.

I used max vg. I usually use 70 vg and above.

I would just stuff the ends of the cotton into the wells. I normally use like a flat blade screwdriver for this. If there is too much cotton to fill the holes, then I would trim that extra cotton by the coil. I've had to do this with silica wick. If I have like 3 strands of silica and only 2 strands can fill the wells, I will cut the extra strand as it exits both sides of the coil.

Thx, I did watch the first one already. Maybe I need to plug those wells better, IDK. I'm starting to think the o-rings might be worn. This is all very helpful and I thank you. Loved that chimney coil. And he did mention that he got leaks when he didn't plug the wells enough.

70vg here.
