I've been hooked on my SXK Crossbow since I got it. Not the very easiest to work with, but a great vape once you get it down.
I've had minor teething issues with both my new SXK RBA's...
The
Crossbow, the airflow was way too tight, I discovered the air hole through the side of the 510 thread wasn't lined up with the hole through the plastic insulator inside, I ran a 1mm drill bit into the hole by hand and it cut a sliver of plastic out of the insulator so the hole was clear all the way through, the air flow is good now..
I checked my spare crossbow (which I haven't used yet) , it appeared ok, the insulator was lined up... The screw up through the bottom wasn't tight though, I inserted the drill bit in the hole while I tightened the screw so the insulator stayed lined up..
If anyone else has an issue with tight airflow and you don't have a small drill bit to run through the hole, you could probably line up the holes by loosening the pin/screw, then poke a paperclip through the hole and wiggle it around to line up the insulator, then re-tighten the screw..
And the
Insider V2, that was all going well until I gave it a clean and rebuilt it with a 1.2ohm SS316L coil, soon after the draw got tight and then I got a "check atomizer" error, when I pulled it apart I discovered the airflow insert had dislodged and it was resting against the coil, it had shorted the positive coil leg and caused it to burn out... The airflow inserts seem to stay in place if there's a bit of juice on them but because I had cleaned it and it was basically dry it had come out...
Looking at photos of my first nichrome build from when I pulled it out I've just realized the wick was probably keeping the insert in place , it was quite a narrow 3mm ID coil so the wick was touching the insert, the spaced 2.5mm ID 9 turn SS coils I wound were significantly wider, about the same width as the airflow insert, so the wick probably wasn't touching the insert which is why it came out so easily:
Since I'm unlikely to change inserts, next time I pull it apart I might give the insert a light squeeze with side cutters so they leave a bit of a scar on it so it's a tight fit in the hole and cant come out accidentally in future... If I don't get too heavy handed with the side cutters I should still be able to get a small screwdriver under the edge to pry it out if I do need to change it...
