My confusion was that if modules mounted within a rack are designed to
be some whole number of units high minus 1/32" then to not take up 1U of
space the support would need to be no thicker than this. But, I think
the resolution is that while the front bezel is nU-1/32, the height of
the rest of the unit (top to bottom cover) is less than this and leaves
space for thicker supports.
"Stuff fits." I can send you pictures if you want. ;) These problems were solved decades before either of us was born. (and I've got twenty years on you)
Did you make your own supports from angle irons, Dave? It sounds like
getting 1.5 in sq angle irons 1/8" thick and then drilling custom holes
for mounting to the rack could work well here. I expect the trick is
drilling the holes at just the vertical height so that the modules sit
on the angle iron but the flanges still mount to the front panel.
No, I'm too much of a perfectionist (read: snob) (and have too little free time) to do that. I get proper rack rails, usually Navepoint these days.
At the museum, though, we occasionally receive equipment with angle iron stock, and sometimes even [puke] WOOD, used as rack shelves.
Use the right tool for the job.
Or, maybe slotted angles are good enough and customizing an angle iron
without slots isn't necessary.
It's possible to overthink these things. Just sayin'.
