Davide Mini Glassomizer coil rebuilds too airy, help please?

[tchavei]

something must have changed... new wick material for example? Or even same material from a different back? Misslabeled ekowool 2mm with 2.5mm would explain the diference but I can't remember right now what you're using as wick material

 

[tchavei]

Just saw you're using cotton... thats kinda fincky for me to use (can't precisely know how much or how compressed each wick should be so it would be hard for me to replicate the results)... Try something else? Like I said... ekowool, silica wick? At least you know the exact spec of it and so you can reproduce the build over and over again?

PS: my 29 AWG Kanthal A1 coils made around a 2.5mm precision screwdriver (8/7 turns) Gives me 1.75Ohms (varies between 1.7 and 1.8 depending on juice)... you say you use 28 gauge? 12/11 turns should give you well over 2 Ohms I believe?

Just as an update to all of you out here, I've just made a new coil to try out. Clocked at 1.6 ohms, I made a small change that seems to have impacted the draw - I positioned the centre pin positive ridges (?) to be perpendicular with the coil. Could that be the simple solution? I know that in an effort to make the perfect coils I was aligning them parallel with the coil, could that coincidentally have made the whole thing airy? I never paid much attention to them!

What do you think, guys?

Cheers!

I'm using cotton.

How would you do silica on a micro/nano coil? I only have the 3 mm silica. And cotton.

11/12 micro/nano coil usually gives me 1.5 ohms - now, since the label fell off my Kanthal spool I can't remember if I bought 28 or 29g, I was thinking it was 28g, maybe I'm wrong? Hehe

well, I don't know your atty but on a mPT3, putting the coil at 45 degrees toward the wicking slots makes a tremendous (worse) difference as when the coil is perfectly aligned with the slots (has to do with the wicks jamming between the slots and the coild at an angle)... Just try it out and report back

Whats your inner diameter? Can't you fit a 1mm silica wick? 1mm ekwool is actually a hair bigger than 1mm so you can't match 1mm i.d. with 1mm ekowool (should be rather: 1.5mm i.d. = 1mm eko, 2.5mm i.d. = 2mm eko and so on).

Oops, just found it

I don't have ekowool, though.

it was just an example... cant you remove some strands from that 3mm silica wick and use that? With some tweezersm you should be able to skeeze some in there no? Just to eliminate the cotton as a problem...

btw, in some stores 29 awg is sold as 0.30mm and in others 28 awg is 0.30mm... thats another reason I prefer metric. Anyway, my wire is marked as 29 awg / 0.30mm

If I remember well the store I bought had a few 28g with different metric, I chose the 0.3mm. Thanks.

Have you seen my comment about the centre pin parallel / perpendicular to coil? Do you think it could make a difference? Cheers

 

[tchavei]

In all honesty, I don't know your system but since the airway usually has to pass through the coil (so that the vapor is carried out) it seems quite logical to me that any coil configuration or positioning will have a great influence not only to vapor production but also in providing a more o less clear path for the air to flow. In my pro tank for example, when the coil is placed at 45 degrees, the added restriction will increase the draw one needs to pull the vapor out. Why don't you try the "old" configuration and see?

Thanks for all your input, guys! I will give it a try with different back to basics setup and report back.
