Hey there GC. I'm currently working (or wanting to start working) on a glass bottle bong. I wanna make something fairly permanent and reusable. I have 2 glass bottles, one is a cool Mexican soda bottle for the main part of the bong, and one is a little aged shot bottle from a bottle of bourbon than I want to turn into an ash catcher. What I'm wondering, is where can I get glass tubes and such to make the stems, especially one sturdy enough to hold up the ash catcher/bowl? We have one shitty little gift store/headshop in town, and they only sell cheap-o $20 bongs, and rolling papers and stuff. Nothing of quality or individual bong parts. Also, where would one find those little rubber grommets to seal off the holes? I also plan on running down to the hardware store to get some diamond drill bits sometime this week. I'll post pictures when it's done!
