          the thin end of the shim. I simply shove them into the foam and
        
        
          allow their wider heads to wrap around the tip of the shim. If
        
        
          you have a more traditional sub-roadbed such as plywood, you
        
        
          could try small hinges attached to the end of the shim.
        
        
          With the shim securely hinged, I turned to the lock itself. Small
        
        
          padlocks, while more prototypical in appearance and action,
        
        
          wouldn’t work in this setup because they would have required
        
        
          access underneath the layout. In addition, I preferred to main-
        
        
          tain the clean look of my layout’s fascia and not have padlocks
        
        
          hanging everywhere. Ideally, each of the locks would be set
        
        
          into the fascia directly under the switch it controlled.
        
        
          An online search for a solution turned up cam locks. Available
        
        
          from a variety of manufacturers, they’re used primarily to lock
