How about steel channel? Years back I came across some ARA racks
mounted on what looks like a 2" wide upside-down U channel, cut to odd
shapes like it had to fit into a corner on one end. Black over sprayed
in dark blue in places. Shock mounts fastened to it with special
hardware that wouldn't shake loose. It's not large or thick, but the
rust says it's not aluminum. Fairly thin, probably weighs about the
same.

And while we're on the topic of aircraft mounts, what exactly did
those early ATC slides fasten to? Knobs on front with little
tongue-type catches behind, looks like they're supposed to dog into
something? It's sitting on the kitchen table, Mike - in all its black
wrinkle glory. Weird (to me) DY-17 dynamotor has no opening on the
ends, only slots around the edges. The spokes are there where the
openings are on others, but solid metal instead of the screen.
