Koh Gen Do Problems ):

[OhmzRaw]

I bought a bag of KGD organic cotton to re-wick my back up device. I am using it to wick a top coil device and I'm not having much of a success. I'm getting a lot of vape but hardly any flavor/taste. I am using 100% VG juice and still no luck so i tried a 50/50 PG/VG mix and i get a slight taste. I don't get any burnt taste or anything, I just don't get a full on flavor, its like its not giving the full taste of the flavor. My coil is 32 Gauge at 2.0 Ohms. This is a regulated device so I can't drop the ohms.

The coil I'm working on is similar to the one in the PIC below.

That's a pretty small wick area to be using cotton.

You might have better luck using silica.

 

[OhmzRaw]

So cotton won't work in this?

 

[Hans Wermhat]

I've seen that device before. A co-worker had it. It sucked. It didn't have any flavor of cloud production with the pre-built coils either I bet.

 

[OhmzRaw]

Mine isn't exactly the same device... the coil is similar but the device is different.

How many puffs have you taken? Cotton usually has a little break-in period and you'll need to take 5-10 puffs before it starts producing flavor right.

Also, with Japanese cotton like Koh Gen Do there is an outer skin-like layer on both sides of the sheet. You'll want to very carefully peel that skin-like layer off each side before cutting your wick. It won't hurt you if you vape it, but it reduces the wicking efficiency and can dull the flavor.

I'm totally unfamiliar with that atomizer. What is it called? Who recommended it to you?

I'm not saying that cotton definitely won't work, but from the way it looks, the wick area appears to be extremely small for cotton. Most clearomizers using that size of coil use silica string.

I'd have to agree with Bad'.

In your application - the resistance, small wicking pathways, small coil surface area, unknown wick density and in-coil compression (which in this application can be highly sensitive)... all add up to likely a better performance with silica.
As an alternative, running a higher PG percentage might help a bit, if you continue to use cotton.

Hello OhmzRaw. Welcome to the forum. When you say a "top coil device" do you mean its a 'top feeder' as in the juice travels upto the coil at the top of the tank? If so you will need silica wick not cotton.

Also 100% VG juice is very very thick so is harder to get to wick efficently.

 

[OhmzRaw]

Yeah, the flavor travels upto the coil.

 

[OhmzRaw]

I will give silica a shot. How many mm should the silica be?

 

[opticruby]

This is your problem. You see cotton wick is to soft for the juice to travel up.

What diameter is your coil?

I would say you want around 3 or 4 strands of silica through your coil and cut them just above the bottom of your tank.

 

[OhmzRaw]

I'm doing 7 wraps around a 24 gauge needle. So diameter should be about 1.3mm

 

[Baditude]

The same diameter as the coil.

Seriously, I would keep the cotton and get a different back up device.

 

[OhmzRaw]

I have the ego one, Evic VT (Coming next week) Kbox and subtank nano... At the moment I'm using Native wicks. Is KGD better than native wicks.

Can i use KGD on the Ego one?

 

[opticruby]

As baditiude said same size as the coil. How I used to do it when I used silica was to wrap the wire round the wick, I'd fold the eick in half wrap the kanthal round and then cut the loop on the one side so it opened up. Then I'd have the coil in the middle and 2 strands of wick hanging out either side.

I have seen it done but dont know how hard it will be as I havent done it myself.

A lot of people on the forum talk about big top the range devices but I think it dosent matter what you vape on the main thing is your vaping so if top feeder tanks are what you like even for a backup device stick with it and keep trying with that silica, you'll get the hang of it.
