This isn't very close to what you want to do, and I actually considered not posting it.
Really I'm open to reading about most ideas. I'm not super happy with my current setup but the actual outcome is pretty open still.
This could definitely be an option, I didn't even know the plastic carriers existed so that's possibly useful.. Your point about moving the CMS and circular saw blades (no RAS but same idea) to the same location is also very worthy of thought.
I'm even re-considering the "wall" theory.. I don't have a wall nearby but there is an overhead "loft" that I could easily put a drop down hanger from so that could be a possibility.. I'll have to check clearances and see how the cabinetry winds up looking. Most of the parts landed a couple days ago so I've been staring at it briefly in-between fall yard chores which are kind of taking precedence at the moment heh.
