Well described, Andy.

This was what I was going to do with my big Warren Truss tube (the square
cross section tube you've seen on my large mounting)- build a rig like that
for my Perkin Elmer flats, so I could test other amateurs' Cass. systems.

I gave up, though, and gave the tube to Art Bianconi. I'm all used up; never
feel good anymore, thanks to my doctors, who have me stuffing my face every
day with toxic chemicals. Have to take care of my terminally ill wife. But I
did have a rig just about like you described in mind. Thanks for your faith
in my ideas.

Dave
