BTW .. an interesting side note for when the Surgical Grade SS caps come along.
I have
'another tank' that is made out of the SG SS and I've noticed an interesting trait of them. It turns out that if I
vape a
tank low and go to re-fill it (I use the bottom method just like the vid that Chief posted) the carto pushes down just fine to re-fill but when I go to push it back into the bottom cap it will not go in until either the carto or the bottom cap (I don't know which, maybe both) has cooled down a bit. Seems to be a bit of heat expansion going on, this never happens with the Delrin Phiniac caps.
Now this is
not an issue, it only takes a couple of minutes to cool down and then it pops right back in! But the first time it happened, I was all like "what da ...." and pushing and pushing and turning and turning and cussing and swearing!
It wasn't until the 2nd or 3rd time was when it finally hit me what was going on, lol.
