Hi guys,
Thank you so much for the compliments. They make it all worthwhile. And thanks Pete - I should have mentioned it is 1:29 scale. Can't wait to run a mixed train!
I worked last night and a little this evening wrapping things up. The truss rods have been painted green per Grande standards. The ends of the letterboards have been trimmed using a circle template (anyone else remember circle templates?) The roof end beams were cut from 1/16" basswood and attached to the roof.
For the roofing on this project I tried something different. I am using 220 grit sandpaper from Auto Body Now. It comes in a 2 3/4" wide roll, 20 yards long and is self-adhesive. I posted a link to a pic of the prototype from the Denver Public Library at the beginning of this thread, but even zoomed in all the way I am unable to see how the roofing was laid down. I began cutting strips and attaching them:

Bad idea. I sent a pic to my son. As he is wont to do when dad goes astray, he offered a gentle correction. He sent along the pic below of a narrow gauge coach that clearly shows how roofing was applied on the ends:

I cut approximately three million more strips of sandpaper and coated the rest of the roof. I can tell you that cutting sandpaper eats #11 X-Acto blades up in a hurry! Here's how the roof looked when completely covered:

I then spray painted the whole roof black. Next I added the roof vents and smokejacks, all from Ozark Miniatures. The sandpaper adhesive is not as fierce as I had hoped, and this evening I will be adding tiny drops of glue to the undersides of the roofing in spots:

I am still waiting for some marker lights from Shapeways, but once I add those this project will be complete. On to the next!
Cheers,
Matt
