@natural farmer I've looked at ideas for a less fragile stem. Ideas have been bouncing around in my head as people want strength but also the ability to reclaim.
A full wood stem wouldn't allow easy reclaim so I suggested a glass or stainless liner.
I am also toying with the idea of having the ability to pre-fill some glass 'bullets' and have them fit into a different mouth piece which could be fitted with a 510 drip tip of the users choice.
So the glass goes in one end of the wooden dowel, again this could be sleeved or metal if preferred, and the drip tip in the other.
It's now when I wish I had the abilities of
@thekarmawhore to turn the 3 images into one.
The glass could be an extra short 18mm joint instead.
I also posted about the possibility of using a modified one of these
which would just need prettying up a bit with a wooden mouthpiece.
@DieHard found that his Mom's long finger nails stopped her being able to press in the button so as long as you keep yours trimmed you shouldn't have a problem with a recessed button.
