Landforms Around the Trestle

The plaster cloth is cold to the touch, so it is not dry yet.

To install the trestle (the last step to finish the track-work) I needed to actually start the scenery by creating the landforms around the trestle. In addition to the creek bed directly under the trestle, I am creating the landforms in the vicinity--hills on either side of the creek and a cut through the hill for the track.

A number of techniques are possibilities for creating 3-D landforms: pink foam insulation board, screen and plaster, geodesic foam scenery, paver sand à la Paul Scoles, rosin paper, or glue shell. I have chosen to use cardboard web and plater cloth, largely because I have a bunch of cardboard around the house--Ikea packaging and the seemingly endless stash of boxes from the move across the country. While it has fallen somewhat out of favor, I will describe the process of this old-school technique.

The first step is to cut 1 inch strips of cardboard using a utility knife and a metal straight edge. Then, the framework for the landform is created by weaving the strips into the desired location. The ends can be attached with a staple gun or hot glue gun. To attach the strips to each other as they are woven together, either an office stapler, hot glue gun, or white glue and clothespins can be used. I used the office stapler and hot glue gun to save time; I also burnt my finger with oozing hot glue.

After the cardboard webbing is satisfactory, the next step is to protect any surrounding parts of the layout from the application of the hardshell. While using plaster cloth is a lot less messy than paper towels dipped in plaster, the potential is still there for plaster drips to cause an unsightly glob where you least want it. I covered the track and cork with blue tape and the backdrop with wax paper. This photo shows the webbing complete and the rest of the layout protected, ready for the application of the plaster cloth.

I had a roll of Woodland Scenics plaster cloth on hand. I picked up a budget kitchen scissors at the dollar store for, wait for it, a dollar, and it has become the dedicated plaster gauze cutter. I cut the pieces at 4-6 inches, and piled up a bunch of them before starting. The application is fairly straight forward. Picking up a rectangle by two corners, it is dipped into water just long enough to wet the surface, held above the bowl or paint tray to drip excess water off, and then it is applied to the cardboard web.


I overlapped the pieces by about a third, and then, smoothed out the plaster with my finger at the overlap to adhere the two pieces together. I also used my finger to smooth the plaster cloth down as it joins the plywood. After the plaster dries, I will double check the trestle in location. I may add a final layer of Sculptamold over the hardshell and a rock casting at the vertical face of the cut seen in this photo.
