Sliding Foamcore Doors (and Windows)

 One thing that I was really determined to accomplish in the model was to make sure my doors and windows were actually operational. I wanted my sliding doors to actually slide, so I had done some research beforehand on how they may work. Some of them mechanisms were more difficult to implement in my model because it is smaller to work with, however I found out that using grooves in the foamcore may work. 

My research on grooves of sliding doors consists of  the
use of Google images

Trial run with tape, do these walls work?
(Apparently not, had to cut down on some
measurements)
