What materials can I use for scratch building a "simulated/freelanced" ferry slip surface (I mean the boards directly underneath and perpendicular to the rails)? Matches, craft sticks, square dowels, etc.? I need something about the same thickness as HO cork + ties. The ferry slip will be only 3" long. Also, how can I keep the track in gauge after removing the ties (code 100)? The ferry slip is shown at the bottom right inside corner. The radius will be a little tighter than shown (flex track) to get a 3" straight on the ferry slip.
