If one reads the archive: I suggested PVC using stainless steel
nipples to "isolate" the "heat". I suspect the combo of your heat
dissipation and the SS insulation would be a permanent "fix".
Everyone on the list nixed my idea and gave sources for metal pipe,
or wrote nothing.
bc semi-vindicated, and thinks Josh should "join" tap-l.

My PVC Ruben's tube didn't melt, because I put a 2 inch wide strip of
folded-over (a few times) tin foil along the axis with the holes. I
drilled the holes through the tin foil. It conducted the heat away
nicely. Occasionally I would have to redrill to clear out a few of
the
individual holes that melted a bit, but it wasn't bad. However,
the tube
will eventually bow upwards, especially if you use it for extended
periods. It got to the point that I couldn't use it anymore after
20 uses.

bc suggest asking the tap-l people; they evidently all have one.
