While not adding to your solution I saw this posting and had to put in
a plug for my simplification.

I made a simplification to Joe's beam and want to let others know.

Instead of paying for those hose clamps, I simply use a short piece
of the tubing to hold the tape. It takes a little Dremel grinding to
remove the step inside, but makes a nice, clean design with the hair-
pin match inside.

Looks good.

I always wonder from where you people get the PVC tubes.
My local construction markets don't.


Since you have it, can you try to make the center elements movable,
this should work with the PVC tubes also.
