Hi Alan, 

I think this was already suggested by Gregory Hunter (if my memory serves me 
correctly), but with all the talk about fiberglass coated Al duct, I think it 
might be possible to fill the thing with some sort of fibergalss resin that 
would work just as well. Basically, one could find an inner tube with the 
right ratio of diameters (outer :cross section) and find some way of filling 
it with the resin until the proper size is reached. Then you could just shape 
it as it dries, getting rid of all the imperfections and forming it into a 
nice donut shape in the process. Then when it dries, cut off the inner tube 
and sand it down, then add some more coats of resin then coat the thing with 
Al tape. I'm not sure how expensive fiberglass resin is, but if it isn't 
cheap, you could always use it on a small toroid with maybe a wheelbarrow 
tire inner tube or something along those lines. An advantage of this would be 
that one could fill the ! tu! be to nearly whatever size they want, without 
overfilling it and making it burst, which would probably be quite messy... I 
haven't tried this yet, so it might not even work, but it probably should. 
Any suggestions? 

Just a thought,
