Here's another thought for rails - I may even try this as an experiment. Cut
a 1 piece rail (I voted for 26U) out of 3/4 x 3/4 aluminum. Instead of
drilling and tapping the rail (aluminum is too soft), drill larger holes and
use the SKB style clip-ins wherever you need threads. This will also build
in some slop if you have alignment problems.
I've been planning a IIIC style setup, but I have to admit Ken's pic is
awesome - especially if he populates it with 9 MOTM-300s as illustrated!
