Me and my buddy made this(i got the idea, he did the work, i have no glass working experience and no dremel experience). Well if you look in the pictures, the hole is the standard size of most high end bongs, if I'm correct, its 9mm. But the downstem uses a(again, if I'm correct)14.5mm, the size one higher than standard. Well, as you can see, it doesn't go very "down". Any suggestions on how to help that? And the original seal was JB weld, the weak kind, and the downstem was actually not capable of pulling out. Any other sealing suggestions? and getting another bottle is possible, if it's past the point of fixing. The blank spots used to say "VOSS", it was the brand of water that came in the bottle. We took the label off and are going to put our own logo on it. This bong's name is "Vossta", for obvious reasons. Thanks for looking!
