Finally got 100 feet of kanthal 26g. Went ahead and did 2 micro coils at .6 ohms. Out of this world flavor and vapor. Damn, delicious.
Two weird things that I noticed today. I don't know if they started happening today or not because I don't usually pay attention to that (which would require me firing the REO without the door looking at the positive pin). One, sparks. I noticed that when I released the firing pin, usually I'd see a little spark in there. The second, one of my springs kind of collapsed. By "kind of" I mean it was completely different from when I first caused a short on my first REO. This time it didn't just collapse as usual, in fact the only way I noticed was because the firing pin was going lower than usual, but the REO never stopped firing, and the battery was cool. It never got hot, red, never smelled burnt (like the first time where I actually smelled the strong burnt odor). The spring was cool to the touch, it just had semi-collapsed. I tested my coils for shorts and everything was fine. One funny thing though, ever since doing .6 ohms, both units get a bit warm, and ofc the RM2 gets burning hot. Then again this is pretty much my first time venturing into real sub-ohms (my previous coils were, the lowest, 0.8 and I ditched it. I was rolling with 1.0-1.2 ohm microcoils)
The sparks were solved by adding a good amount of noalox on the firing pin. The spring, well, I pulled it back up but put it aside anyways and replaced it with one of the spares. It is curious because my first short the spring totally collapsed, got hot and smelled burnt, and I couldn't fire it unless I pulled up the spring. This time, it was firing all the time, it just collapsed a little to the point that I could fit the battery without pushing it, but it wasn't so collapsed that the battery would fall. They haven't collapsed at all again.
What do you guys think?
Edit: Forgot to say sparks only happen when using the RM2s. Tried a couple of cartos and didn't happen. Interesting, I'll have to take a deeper look at my coils, but odd since they passed all the tests for shorts.
Edit2: Relooked my coils. Nothing wrong. Tested them again on multimeter. Nothing wrong either.
Edit3

p): Sparks issue is solved completely. Filed the firing pin and readded noalox. The spring issue, I'm still puzzled. Obviously there's nothing shorting, and if the coil itself had a short I would have collapsed the spring again. Yet it's firing perfectly fine and since the spring only collapsed a little, it must have been a small short. Actually thinking back I was using my multimeter a lot, so maybe somewhere in that craziness it did a small short. But I'm 100% positive the coil wasn't, since it has been firing all along. I need to be more careful with my multimeter I guess.
