Horwood Brothers Gas, Oil and Service - Rail Scale Miniatures.

[Ensign]

Hi Tom, everything your doing is looking wonderful!
When I built my Horwoods, I used a method that used 2 layers when it came to the roofing.
I had fully documented it in my RR Lines forum build, but we all know what sadly happened to all of that stuff.
I wish I still had my Horwoods diorama to show you what I mean, but I sold it to "Little Canada"
However I have since used the same technique on other structures I have built.
So for the first layer you can use styrene or cardstock whatever you choose.
This first layer ends up being the ceiling of the interior.
You can mount all of your LED's to the underside of this layer where you plan on having lighted interiors.
Then feeding all of the magnet wires for those LED's up through that first layer, and then running those wires to the LED distribution board, as shown below in this structure.

.

I then add the second layer in this case scribed wood flooring over top of the magnet wires.
In your case it will be the cardstock roofing panels provided in your kit that you have already cut out.
Instead of wooded flooring your upper panel will have the gravel roofing material.
On my Horwoods I glued the first panel with the LED's in place, and left the gravel roof panels loose to allow me access to the interior to allow me to do the final magnet wire hook ups to the distribution board/boards.









This method allowed me to place LED's where I wanted them to be for interior lighting.
Also allowed me to run all of the magnet wires over to the place that I had the distribution board placed.
I cut away the first layer leaving an opening where the distibution board was placed.
The second/top layer hides all of that stuff when you are finished, and it worked reall well for me on my Horwoods in the end.
