Diorama Base and Wall Construction
I created a diorama base for this structure from some left-over plywood and Masonite board. The first photo shows the local loading and unloading side of the structure.



The next photo shows the track side of the structure.



I decided to try something different as the method for assembling the walls of this structure. The DPM corners on their kits always looked wrong to me. What I did was sand the outside corners of the wall sections at a 45-degree angle (making miter cuts, effectively). The close-up in the next photo shows the result. I did this using a disk sander.

Update: After seeing a furniture-making-shop model at nationally-known Master Model Railroader Gil Freitag's layout recently, I decided to expand my project to become a bigger complex of buildings. The new diorama base measures a scale 150 feet by 210 feet. It's been cut to fit the shape of its spot on the layout.
