From my hero Dr. Stong. Score around the tube and then tie a cotton
string around the score. Soak the string in lighter fluid. Stand the
tube on end and light the string. The part above the string will heat
more than that below and the tube will crack cleanly at the score.
(Assuming you hold your mouth right and the moon is in the propper
phase. ) :-)

Gang,
Got a piece of glass tubing (similar to Pyrex) which is .490 ID,
625OD and I need to cut a piece about 11/16 long. File won't touch
it, glass cutter won't do it, have been trying to score the outside
with a thin "cutoff wheel", which scores it, but the stuff won't "snap
off" as expected... just shatters, even past the score mark. Am I
going to have to cut completely through with the cutoff wheel to do
this?
Ken.
