In this video lesson with Martin Tarnrot, learn how to model wooden planks for your model railroad layout. These wood planks can be adapted for any scale from N and upwards and are a good match for layouts set in the early days of lumber and saw mills. Martin uses one sixteenth of an inch thick balsa sheets for his wooden planks. He cuts the sheets into segments of 45 millimeters, making severals scores before cutting all the way through to avoid cracking the wood.

Martin has created a balsa slicer tool to make creating the wooden planks easier, speeding up production. The balsa slicer is made up of a base of a four millimeter plywood with a balsa spacer and a razor blade held in place with thread. Cutting is not only fast, but also uniform with this tool. The next step is to give the planks an old gray color by dipping them into a color mix of burnt umber, white, black acrylic paint and water to thin it down. The result is a warm gray tone.

To make the horizontal and vertical beams in the plank, Martin uses two millimeter thick pieces of balsa wood. After slicing them to two millimeter widths, he paints them with the same gray color. He lets them dry overnight and then begins on the assembly. Assembly starts by arranging the planks flat along a ruler and then gluing the horizontal beams in place with wood glue. Martin goes on to demonstrate how he weathers the planks for the final result.
