Hi John,
about the turbine tube.........
while i was putting stuff in our recycle bin one day, I spotted some hair spray cans( my daughter is a hair stylist)..........anyhow, Redken brand hair spray, and prob'ly others, come in a tall narrow aluminum can. the ones I found are 2" diameter, about 9" long and pretty rigid even with the ends cut off. being aluminum, they prob'ly polish up nice. I know they make bigger ones too.......
Just a thought,
Bob the Fool :blink:
