I would feel much safer with the tube there!!!! 
Fascinating...just thinking out loud here...if you removed the insulating washer that goes between the top of the pos disc and the underside of the base and replaced it with solid insulating disc (with a hole drilled in one edge for the pos con screw to go through) then just drilled through the hole works with a 1/16" bit, would you even need the tube?, juice would have no where to go except up into the wick well?...you know, that's worth chucking the whole assembled base unit up in the lathe and trying...nothing some epoxy and some wire and solder couldn't reverse if it didn't work?
About the only issue you may have is a need to finger the air hole when you squonked to draw your juice up...
Only problem with this concept is that the juice would be in contact with the brass center pin and plate.

I never got around to trying my G-Tank-US with type B eGo tank cartridges. Well, I have some ordered and I'm wondering if I should cut my SS wick flush with the spiky protrusion on the middle piece? Currently, my wick extends a few millimeters beyond it and it's working fabulously. I'm thinking if I leave it as is and try to puncture the silicone on the tank cartridge that way, I'm going to monkey up my wick and coil.
What say you folks?
Dirq, 1.1 ohms is really low, I would add some wraps to spread the heat over a longer wire. This should help with the exposed leg from the post to the wick. If that part glows, then it is actually burning the juice which is why it tastes awful. It sounds like you are close though.
When all assembled you should be able to hold the button down for a reasonable lenght of time and see no glow through the air inlet. Also are you quenching with liquid between torchings? It may also not be oxidized fully and hence the low readings.
Ok, when I get home Im going to rewrap it with 36g kanthal and torch it a couple more times. Yes I am quenching it with liquid after each time I light it on fire.
Each time I have an issue I get a really good response such as yours that helps me understand things a bit better. I get a bright orange glow looking through the air inlet almost immediately. So off I go to try again lol. One of these days Im gonna have that "aha" moment.
I just wrapped a new one on the same wick using the 36g (before I checked to board saying not too) and went for many extra wraps and it came out to 6.2 ohm. So now if I could get somewhere in the middle Ill be good. Ill go back to the 32 and maybe 8 wraps?
the pos screw on my gtus is very hard to screw and unscrew, any ideas on how to make it ez to screw and unscrew? it has become suck a pain that i dont use it much now and i really like it
