I'm thinking about building a new tube for my homebuilt 8" Dob this
winter. Earlier this year I saw a web page on the Black Knight
Telescopes site that had some tips for building a tube using Sonotube
with laminate wrapped around the exterior for added stiffness.
Unfortunately this particular web site is no longer in existence.

Does anyone else know where I might find information on using such a
technique to build a tube?

Thanks.
