The Control Panel.

I built a 12" x 18" x 30" box from 1 x 12s and 1/8" plywood. The vertical member is in the center, supporting the sides. Eventually I'll add doors. On one side I put the power supplies and relays for block detection, the backside will be space for storing the cables and other supplies. As you can see the entire top is the control panel. I started making the control panel from Plexiglas but it shattered from drilling and attaching components. A piece of Formica attached to the bottom with spray contact cement resolved this problem and made a nice looking panel. I even think the shattered Plexiglas adds to the character.
