Thanks Eddy,
i like the big tube idea, I just don't think it's easy to terminate at the ends, with something to take the linear brg blocks and to get down onto the screws. Composite sounds good, but it's heading away from mass, and I hadn't appreciated the value of mass, though composite is good for damping.
