Curiously, after my last string of posts, the uneven wick drying has continued. I've tried everything. In my full mech peko, I replaced the 510 jack and vented screw (Threaded into the delrin this time!!!), steel wooled all three solder tabs and brass parts, scrubbed the threaded rod with a wire brush, cleaned most parts that don't come in contact with
juice with contact cleaner and hit all contacts with deoxit gold (I know it says it's for gold contacts, but it can't hurt right?) everything has been re-assembled tight and right. I even changed out the atomizer (and thus, the flavor) to my 3rd derringer which was brand spankin' new. I eventually soldered one of the small nuts onto the positive solder tab so it would be easier to disassemble/reassemble and in theory remove one possible (albeit small) variable.
The coils have been changed numerous times. I make them all the same way using the artists' coil jig with a custom arm. I've been using the same coil builds for more than six months. They are carefully "broken in" and they are as centered and even as I can possibly make them. They light up evenly when dry burned. They produce an even amount of vapor when the top cap and afc are removed. The vapor production is as good as my little tensioned, 6/7 wrap, 5/64" ID, 29 gauge, ~ 1.3R (0.6 - 0.7R total) coils can put out. Six coil changes have produced the same result, each time on the same side of the RDA. I know its not the RDA, because after I couldn't fix the first one, I removed and thoroughly cleaned it, then installed the brand-new Derringer 3.1. the problem continues...
One wick still gets dry before the other.
SO.... I throw on some SMXdrifter (Russ) on youtube and watch some random video about some random topic. He brings up air hole positioning. He notes that when a dual coil RDA is installed, and the air holes (and thus the coils) are positioned so that the are facing the sides of the mod (as mine were), it causes liquid to pool into one side of the well based on how you hold your mod when you vape. Strangely, the coil that is pointing downward is the coil that has been staying saturated. He suggested canting the RDA so that the holes are horizontal when you are actually
vaping. When he was having the same issue as I am, he reported that this solved it. So I re-install my Derringer so that it is canted. seems to be slightly better, but only a few sessions will really tell.
I'll keep you guys posted. I'm planning on doing some wire-modding (I finally found a wire mod/switch spring combo I like) to this one, based on the fact that my backup peko with wires does not have this issue. I can't think of anything else I can do to alleviate the situation.
Has anyone else experienced anything like this with their peko?
