I've got a question about the 510 on my hcigar Kayfun 3.1. The center pin extends out 1-1.5mm past the end of the 510. I know why, but..... I don't have a lathe to fix it
. Anyway, this is preventing it from sitting flush on most of my VV/VW devices, and I would also have to make a special center pin for all but 1 of my Mech MOD's. So, my questions... Is this normal for a hcigar 3.1? If so, does anyone know if an authentic is the same way and if not, could I solve this by buying the drip collector from Svoemesto to use on the hcigar.... compatible?
