O scale Scratchbuilt Coal Tipple made from Styrofoam Sheet

Nice job.  What did u use for the windows?

Windows are made from strip wood frames.  Looking for a source of O scale laser cut wood windows.  I have used Grandt line plastic windows for other smaller projects.

Thanks, they came out great.  Was there anything special you did to finish off the ends of the styro board?

Really nice.  The windows look very good by the way, so whatever you are doing will be hard to beat..

 Yes Styrofoam board is very fragile.  I always apply a coat of carpenters glue to all edges.  I also use a very sharp razor knife and a steel straight edge to score the foamcore board when cutting. Do not apply a lot of pressure.  Several light strokes is best.

I also use wood strip to reinforce the corners and edges of the building walls.

Wow, really great job. Hats off. I gave up with this material. Every time I would try to paint it, it would warp like a potato chip. How do you seal if from the moisture?

I first reinforce with wood strips.  Then I paint both sides and edges to prevent warping. Once both sides are painted the "warp" in the foam board disappears.
