I have been a member here since 2009. I started vaping in 2008. Finally found the good stuff with more advanced atomizers than a Vivi Nova (nothing wrong with those, I used them for all these years).
Thanks for the words of encouragement everyone. Found a 3 mm screw the right length, a friend dremel'd the head to size, all is well with my Kayfun again. Now to get a couple of spares . . .
