Well, I've seen pipe organs made of various materials over the years.
I intend to build an organ for outdoor performance that will be
transported by truck.  Since environmental conditions can be quite hot
and humid here in the South, I'm considering aluminum, plastic or glass
tubes for pipes.  What do you guys think?

Thanks,
