Brent, the elbows are 4 inch PVC, schedule 40, thinwall. The openings were about 1/16 of an inch to big for the port tube. I "stabalized" the tube in the fitting by wrapping one wrap of electrical tape around the tube. I then used hot glue to glue them together, in case I need to "unglue" them in the future if I need to make any adjustments to the length.
James, The Shiva tubes are spoken for.
thxgoon, the piano is doing ok so far. But the emu eggs on top had to be moved! The last time I experimented with test tones I broke some of the wifes crystal glasses. No more "mistakes"!
