After several false starts I made my control panel for the South side. I started with a 1/4" ply but it was warped. It's only an 8 X 12 piece. Anyway I was going to use a piece of 1/2 ply; but the toggles are too short. So I gave up my idea of a wood / paper/ plexiglass sandwich and used a recycled lamenated sign. I'll have to etch the diagrahm on there. Now I don't like that screwhead on the switch control so I stopped work until I find better screws.
