Has anyone had problems with the bottom screw unscrewing itself? I find after locking/unlocking several times a day that the fire button sticks out more and more because said screw mysteriously unscrews itself.
Been playing around with the multitude of tubes and rings and I think I found one that works. Can't be 100% as I can't try it properly as my wife doesn't now I'm back "smoking" ...
Thanks for the help. Just need to build a coil for my TOBH.
