OK friends... I have builded a cartomizer like the l3oertjie's design, but with all SS components, and only one solder, the needle to the wall of the fitting. The another needle is attached to the central post with two plastics clamps, and that works excellent, the central post is a SS capillary tube with 3.5mm OD, and fits perfectly and firmly into the original gasket of the fitting.
After I finished the assembles, I have tested the conductivity and is PERFECT on both poles.
I have used a fitting of an ego mega carto, and an aluminum sleeve that fits in the fitting, this alum tube is temporal, I will use a SS tube when all works, If I can do it works.
Next, I made the coil, I used 80/20 Nichrome wire 36G, and some strands of Silica Rope that Bubo mailed to me (Thanks Bubo, you are great) and also I have some Fiberglass Rope that I could find in local market (this is marked that supports 550º Celsius)
I have made coils of 2, 2.5, 3, and 3.5 Ohms and more, playing with lengths of the wire, 4 loops, 6 loops, etc.
I have made the wick of 1mm diameter, 1.5, 2, 2x1, etc, with both materials. But always I get a awful burn taste, even with the coil with liquid arround everything, not with the coil dry.
Besides, I think that the liquid evaporates too quickly even with a 4 Ohms coil.
I have washed the rope with hot water, and with ethilic alcohol, and nothing... the burn taste remains.
What can I do ??????
In what part I am failing ??????
