I'm enjoying this journey. Looking forward to see how you handle the roof.

It's only make-believe

Carl,

Outstanding workmanship on another classic Railroad-Line build.

I glued the depot walls together, installed corner braces, and a "stiffener" in the center. I completed the trusses for both buildings. Each end required a special 3-sided truss to support the hip roof. A fussy affair to get the proper angles. The bottom chords of the main trusses were made long enough to provide a base for the 4 ft. wide flat soffits to come.



The soffits are 3 x 8 strip wood, "sistered" to each other on edge, instead of sheet goods. This way, I could get the look I want, and manipulate dimensions as much as I like and trim later. LED lights will be attached underneath here. Hmm, not sure about the soffit being yellow, probably should match the trim white. Comments?



With the soffits attached and before the roof trusses are installed, I can get the lighting started. Attached copper tape for voltage busses and the resistor bridge for 8 lights...7 around the outside and 1 inside.



I use pre-wired warm white LED's which were mounted on plastic lampshades, then drilled thru the soffit and glued them up tight to the boards. To make sure these are aimed down properly, I keep them lit up one at a time, using masking tape to keeps the wires and light from moving in any off-kilter directions...and allow the glue set up in the proper position till it dries hard.



LEDS can be way too bright for models. To find the appropriate resistor that will dim down the brightness safely, I use a commercial "resistor substitution box", where you can switch in the amount of resistance in steps. This allows me to choose the proper value, and will differ depending on the power supply voltage. You could build your own too.
Of course, I actually do this brightness testing in a completely darkened room, or at night.



I soldered all the resistors in place and can now install the roof brackets. These were burned onto a .022" self-adhesive sheet by RSM, and I simply joined two units together to make a scale 4" thick bracket. I'll fill in the tiny seam with modeling paste and re-paint.



I glued down all 8 trusses in place. I can't apply any roofing until I get the lighting finished inside the office, and carry wires over to it from the depot power busses.



I soldered the power wires to the DC power jack, which was mounted just below the resistor bridge, inside the depot. A small 5 volt supply is ready for the 16 lights....



Till next time...moving back over to the two story office..
