Here is my first attempt at building a benchwork foundation for the first section of the City Point layout. Main motivation is light weight while maintaining maximum rigidity in order to allow for portability. My last layout used an L-Girder design. While the L-Girder design was very suitable for a stationary layout, because of space considerations, I need to make this layout movable. A L-girder design would be hard to make portable.
It is made of plywood underlayment. It is cut into 3 & 1/2″ strips and notched to interlock on 16″ intervals.
While it is light, I’m hoping that when fastened to the bottom of the plywood layout that it becomes rigid enough that I don’t have problems with damage to the track work and scenery during moves.
