I recently bought a realy cool bubbler...i smoked a bowl out of it when i got home...the carb is so small that when you try and clear the peice, it pulls hits off the cherried bowl...and doesn't clear it until you cover the cherry, put it out, and then clear it. I tryed to wrap some sandpaper around a pencil...but it doesn't stay on there very well...and its extremely slow lol. KAV
10 minutes...my thumb can't take it... ill try it with a torch though...or one of those candle lighters.
Use a Dremel with a diamond bit, pretty much the only practical way to do it without harming your piece.
