Well guys, I found some thick ass copper tubing (bout 1/2"-3/4"), and some left over heavy duty plastic tubing (aslo 1/2"-3/4") from a commercial spray paint gun. I was thinking about using the plastic tubing as the stationary stem (using hot glue or epoxy to attach it to the glass), while soldering the copper tubing to my big socket wrench bowl, and using that as the sliding piece. Sound feasible(sp)?
