Thought that I would up load some pic's of my baseboards that are constructed out of 6mm play skins sandwich together over small lengths of softwood to make a very strong but extremely light construction. They measure 1000mm x 580mm x 150mm (4 in total) and the inside skin is 50mm lower so the 5omm deep insulation board (baseboard top) to sit into.
The legs are constructed from length of pine and ply wood construction. They simply flat pack and open out into a solid A frame that's very ridged and doesn't flex.
The idea is if and when I exhibit the layout its very light and easy to handle and all folds up nicely for transport.
At the mo. I have just layer foam board sheet's on top as I didn't have the insulation board at the time and laid out the track plane. today I got the insulation boards, cut them to size and have fitted them to each board but I forgot to take some pic's. Fine I've got a layout going.
