I've got a peice of glass that would make a great ash catcher. It has 24/40 male and female ends. I thought it would match up to 18 mm glass but it doesn't. Ideas?
That is the question. They are soo close to 18. I thought that in a Bong 14mm really meant 14.4. That's almost exactly 24/40. But it's very close to fitting 18mm glass.That’s cool, can you rig it up to a bong?
