The Control Panel is simple. It use SPDT center-off switches to control six blocks across the layout. It is 1/4 inch plywood with triangular 2x4 used to provide angle. I simply drew the plan on using a pencil grid (erased) and a sharpee. I need to do a little touch up because my pre-painting drill guide lines are showing through, but it works well and for now it will remain as it is.
