I had to update the control panel to mark the semaphores and uncouplers, so built a new one using Perspex (3 mm face, rest 5 mm). Salvaged the electrics from the old one.
Much lighter and stronger than the old wooden one (shown below). I found working with Perspex a little harder than wood, but on the plus side, the face is EXACTLY 3 mm thick - the Cobalt Alpha Central illuminated switches are very intolerant of over/under thick material, and I had to route the "3 mm" ply on the old panel to get it to work.
