Yes thanks Tom. I did check that file only to come up with more questions.
Thanks for the tip. I was still wondering if these tubes can be produced
successfully by taking a piece of lets say 18mm and filling one end with
glass chips. After its as full as possible, sealing on another electrode on.
the trodes would be straight out. After that, connect the tube via a long
tubulation to the pump and with the tube in a kiln. Bring the kiln up to
about 300c and let it st for two days or so. After it cools off, back fill
with 8mm or so of NEON. Heat the tubulation from the kiln to the seal point
a little then seal the unit off. In the groups opinion, would you think this
would work? Tell me, why to you think that Larry Albrights tubes are made
out of pyrex and why does he double 90 degree the electrode back. (No ASCII
drawing here.. for Kenny)
I am thinking about trying it but not sure if I want to go through the
expense of the set up of the kiln.
