Welp,
There's always this stuff that I wrote about awhile back:
http://www.piko.de/e/plastruct/s-plastruct.htm There's lots of various shapes and sizes. Experimenting with this stuff in
my 19" rack brought up the same problems/concerns as have been mentioned...
Using the "H" columns tends to lock adjacent modules together, the slop in
between the modules is consumed, etc...
Very soon I'll be going to check out some wood places to figure out what
type of wood to use for my cabinet. I'm starting the think this Plastruct
stuff may be just the ticket after all, as long as I use wood screws to
secure the modules in the case. This will allow the modules to be correctly
spaced for the Plastruct dividers.
