Very cool displays gents....love them all. Yep that is what i was thinking of for the bottom of my show cases to mount wheels on them. I plan to use plywood for a base for my large diorama project....not too sure if I can make the large plexiglass cover myself I know they use a special glue that is transparent once dry and it holds very well. My diorama will be of a 60s Gas station with service bay,etc. Ill have to see if I can find one of those MRC gas station kits for a starting point.
