Finally got the RSST wicked and coiled. Decided to use this for experimenting on, and went with a SS rope wick wrapped at the top with some 400 mesh, about 5 wraps to try and act as a sort of juice store to see if i can avoid dry hits, and ran it just through the wick opening to try and avoid leaks. Seems to be working as its def. not leaking at all. The rope is 2mm 7X7. Its fairly tight-ish in the wick hole now, but not too tight, still slides in there. Used 26 guage kanthal but wanted to try a lower ohm coil in it, so ended up at 0.49. 3/4 wraps and wrapped on the wick. Running it on my RA with a fresh battery. Drilled out the air hole to 2mm, (meant to drill it out to 1.6mm, but picked up the wrong drill bit!) as it was just too tight for me at 1mm, and its now vaping like a champ. Lots of vapor and excellent taste, and not a dry hit in sight, and the filler hole plug is inserted in there. If I get some dry hits on it, I will just take that out as that should help, but like i said, so far, not a trace of one. I think you can just about see the rope wick in the image:- Very simple build that should last a month or two before i need to look at it again..very pleased with my bargain basement RSST, and think I will get another one just in case. Edited to say that the 2mm air hole is actually very good. not too airy, but enough air to produce great vapor. Happy with it.
