re: Foreward Phaser Control.
Shaw, something was bugging me about the floorplan of the Phaser Control room you're using. I pulled out the book Inside Star Trek, which has the same plan, and then I looked at Balance of Terror and, sure enough, the set plans don't jibe with the set as constucted...albeit the way you dropped it in, where the moved the door ended up it would actually meet your corridor.
I figured out the differences...not perfect, but it gets the idea across:
Thing is, if you try to make the sets as built accurate in your ship, the wall seen outside the door in the set would end up smack in the middle of the corridor you have roughed out.
Of course, to make matters worse, Spock runs down a curved corridor and then OUT along a radial one to get to the room...which wouldn't fit into that deck space at all.
Hope that helps
