Got my polished Russian 91 and an I-Taste SVD the other day. Did a 2mm coil with the silicon wick and 30 ga wire they send which wound up at about 2.1 ohms. Tasted like crap. Did another one around 1.5 mm with cotton at about 1.9 ohms. Tastes much better. Question is can I disassemble the contraption without draining the tank? It's not a big deal to blow the juice out into a bottle and take the whole thing apart but I see no way to change coil/wick without taking it down all the way. When I unscrew the base it's kind of random what will come apart with it. If just base came off it would be ok but sometimes the chimney comes with it or the chimney ring and out goes the juice. Is there a secret or do you just wait until you have an empty tank to do maintenance?
