Back to the timber tunnel project:
Here is the tunnel and the piece of Woodland Scenics Shaper Sheet material. I thought I would try it to produce an removable access panel. The Material is a bendable heavy foil backing with a fabric (the white to the left of the tunnel) bonded to the foil. This is then coated with thinned plaster. Woodland Scenics sell a special plaster for this that has a longer working time, so you can coat the whole sheet before it starts to set up.
The plaster has not yet been added in these photos, but you can see that it still holds it’s shape pretty well, and will get much stiffer and stronger once the plaster and other scenic material has been applied.
Here you can see the track that the panel will cover, giving access to an area of a long tunnel in case of derailment. Edges of the panel will have bushes, small rock areas etc to hide the edges of the panel. I will enter a post in the near future when I complete this section with scenery, ballast and cliff faces.
