Hi all, I am trying to design a fiddle yard to connect to my small switching layout. It will be build out of 9mm strong plywood. The traverse table will be movable because of build in drawer slides. (yellow bars in the pictures). I am still figuring out how to build a locking mechanism for the traverse table. Any suggestion would be welcome. I am not sure whether to use real code 40 rail on pcb ties or just aluminum strips.
