Redid my twisted 28g for the second time -- omitted the twists at the top and wrapped the coils in the opposite direction to shorten the total length and make rewicking easier. Most surprising is that the resistance is almost the same as my previous build, this time at 0.43Ω. I'll try to lower the center point of the coils another couple of millimeters next time to get them closer to the airflow hole, but it's still a fantastic, flavorful vape.
edit: If any of you are into rebuilding and don't have a pair of ceramic tweezers yet, order one right now. It makes tightening up wraps on builds like this one soooo much easier.
I'm just now noticing that the long center post screw is a little loose and leans a little to one side, but doesn't seem to affect anything. Any cause for concern there?
Look through the air hole. It might be favoring air flow on one side. Other than that I don't see it affecting anything. Can you straighten it? Looks like that plastic nut ought to drop down in the hole (mine doesn't look like that).
Yep, it appears his insulator has come unseated, it should sit down inside the cutout and only protrude a 1/4 of a mm or so.
I would attempt to properly install it/the center post, you should likely even be able to save the build if you're careful (unhook top leads, lower post, the reattach/clip top leads), otherwise it could shift over on you and cause a hard short at some point.
