Super glue and glass pipe?

Sorry, I guess filing isn't the right term here. You can use black emery to smooth, not file, the sharp edges. Black emery is a polishing compound and is available at any home improvement store. There's also another technique which involves heating up a very thin line on the glass and then cooling fast enough to where it becomes very brittle and hitting it gently. This is done by tying tying an alcohol drenched thread around the piece you want to take off and lighting it. Then you quickly put the piece under cold water and gently strike it with something like a piece of wood.
...yea, black emery would most def be the easier way to go.
Hope this helps.

you are correct, and this is the best solution i have seen if the guy wants a quality product when he is done. i first saw this method of breaking glass the other day in a youtube video. and the emery will smooth out the edges. i figure you smooth the edges, if you dont like what you got break it then smooth the edges again, if all that fails then you chuck the piece and say you gave it your best shot.
