Hi all. I had a guy on another (non-train) forum tell me about this. For tunnel liners, wrinkle heavy aluminum foil and spread it back out flat. Use cheap black, grey, dark brown spray paint to color it and then shape it for use as tunnel liner material. When finished, it looks like blasted rock. I’m thinking about going back with some more grey. The first trys came out a little dark. What do ya’ll think of the color?
Here’s a close up. There’s a couple of spots that need touch up but you get the idea.
And a shot of another tunnel with a GP30 for effect…
Aluminum foil can also be used to make molds for casting rock faces, tunnel entrances, etc. Crinkile it up, make the mold shape and pour in some of your favorite plaster compound, and ther you are. I made some rock tunnel portals this way, by making the foil into a “U” shape then pouring in the plaster.
Cool! Thanks. I’m making two tunnels right now and was wondering what to do for the liner.Good tip on the rock casting too. I just made two portals out of card board glued together with a hot glue gun and I’m coating them with newspaper dipped in plaster.
The other way sounds way easier.
That is a great idea and easy method. I have several more to do and I will try it.
Don’t laugh, but on my first layout in the late 60’s I had a mountain that I built using a 12 gauge wire frame and covered with crumpled Aluminum foil. When it was painted, it wasn’t half bad.
What else could I have done in Bangkok, Thailand.[:D]
