Before I can go any further with the building, I need to create the interior details. These will determine the locations of smokejacks, etc. I'm starting with the largest and most important item, the generator. This will be a "good enough" model -- something that will look good when seen through the windows -- rather than a precise scale model. I'm basing it on this diesel generator I photographed at the Diamond Tunnel mine in Eureka, NV:

I began by building up the "core" shape of the engine, using layers of 6mm and 3mm Sintra:

A piece of 6mm Sintra was added at one end:

I decided that the rectangular openings on the sides were a bit too small, so I cut a little off the top and one end to make the openings larger. The rounded top of the engine was made using a section cut from a 1" styrene tube:

Then the sides were laminated with .020" styrene sheet. The styrene wrinkled slightly in a few places when the glue dried, so I filled in those spots with Squadron white putty and sanded it smooth:

Next I added the arched extension at one end of the top of the engine. I also cut and sanded the top of the engine so that one side has a flat, angled surface, as on the prototype:

The next step is adding the various shapes that protrude from the "core". I began with the piece seen in these two photos:

And that's where it stands for now. More later!
