Thanks Eric for the interesting website.I too like the sliding door concept but the problem is those door storage racks on either side of the hangar adds a lot of width to the overall size of the diorama.
I will contact the museum and see what they think.
A certain amount of space will have to be left around the diorama so that it doesnt looked cramped in a plexiglass box.The storage racks in the picture look good as they are not too massive and are of open structure.
Now I will try to get some info on how the rails for the sliding doors were made.If need be I will travel to an old RCAF airfield and see what I can find.
Cheers! John.
