I've been working on the concrete signal cabinet base. The Showcase Miniatures cabinet has a metal extension below the base plate that I could either try to cut off (no) or build in to the concrete base which is the option I decided to go with. I first rounded a corner on a piece of .010 x .060 Evergreen Scale Model styrene strip. Then I cut and built a box around the signal cabinet base to hide the extension with the rounded corner to the outer top to replicate the angle on the prototype concrete. 

 


The base is rounded so I used styrene rod to fill in the corners and then cut the overhang off.

  
 
 
Below is the cabinet in the base. I have yet to sand it to shape.

 

This is the base sanded and shaped to the final contour of the concrete base. It's just slightly oversized. I could sand more, but risk the metal base of the cabinet bulging the styrene out when I put everything together. 

 

The image below shows the concrete base pieces. I created a few more layers for the signal only base to match the base with cabinet's height. I loaned out my Dremel tool so I haven't had an opportunity to shape the concrete cabinet base to the correct contour and then glue everything together. Next step will be making it look like concrete. Then I'll paint my signals.

Sides of the depot assembled.

Merry Chirstmas! Work continues on the Mopac's Blue Rapid, KS, depot. I've assembled the depot exterior walls and completed the asbestos siding on the ends. All windows are glued in. The bay window piece isn't glued in yet as I want to finish the interior to include the floor and walls. I received another order of styrene from Evergreen so I can work on the exterior corner trim pieces. I still need to install the interior trim around the windows/door and the wainscoting. I'm waiting for temperatures to warm up to allow me to airbrush.   South side of the depot Interior view looking west - awaiting floor, interior walls, and finishing North side of the depot - minus the bay window

Work continues on the Blue Rapids depot build

 Continuation of the Blue Rapids, KS, Missouri Pacific build in O scale (Proto:48). I went back and examined the south side of the prototype depot and it appears that there were a series of windows above the freight room door. Using the entry door as a guide, I scratch built the windows and sill. I've noticed that there are three different style of doors used on the freight room. I'm not sure what was used on the south side and made an educated guess to have it look similar to the north side door. The bay window build proved to be challenging especially trying to laminate three sheets of .020 styrene. I made an educated guess at the size and angle of the bay. I still need to laminate one more sheet for the interior of the depot to the bay.  Test fitting the bay to the depot. I still need to paint the north wall and then I'll attach the bay window. I haven't decided on when to install the asbestos siding. I think I may do it prior to installing the bay. There is a wood t...
