Caveman:

I doubt I'll live long enough or have enough cash to find/afford one of those!

I'm going to make this one out of wood. Probably plywood, but my choices of species are pretty limited if I go that route (but it'll save me a lot of work over solid stock).

If I use epoxy as a consolidant with thin wood, can I call it a "cellulose composite tube?"

Of course I can!
