My third generation board then, the frame is as before but the top is a sandwich of stiff card and foamboard. This is the first time i have done a layout board like this so it will remain to be seen if it works out, but it should be robust enough. Hopefully! As you can see below the new board literally goes on top of the Knell Lane one. I want to keep that and maybe reuse it in a couple of years time. I simply have no where to safely store it, apart from where it is now. And no the new board is not lying on top of the track, i put some spacers on the frame of the board to avoid that!
