Hey can anyone help me with my home made glass bong? I already made a 5/8 hole into the bottle. But I new help on the bong parts. I don't know what size of downstem to get for it. 14mm or 18mm?
Did you get the hole at an angle downward? I can't get it to work on my Belvedere bottle or Grey Goose bottle
I figured he's of age if he's wondering what size downstem to get. Sort of implied there dont ya think? I'd say 14 because theres more variety of choices there, as far as length, diffuser's and bowls to fit the stem
