Today I was in Phoenix and was in Capital Metals. They have about a
dozen mill end aluminum tubes. They are 6061 T6 aluminum, are close to
6" O.D., and are about 40" long. The light weight of aluminum and the
toughness of 6061 T6 would make them excellent tubes for refractors.

p.s. I forgot to mention, they are 1/2" wall thickness. This would make
for a good rugged OTA, rivaling and surpassing TMB's. :-)
