I remember Linda Rice's Lockheed had a really cool backlit panel
overlay.
The panel itself was heavy aluminum sheet, but then they added a
plastic
overlay that had an opaque cover. Legends and labeling was done by
engraving the opaque layer.

On the back side of the there were little cavities carved for grain
of rice (well duh!) light bulbs.

The effect was quite stunning.

So does anybody know where to find this kind of plastic for the
overlay?


Thanks,

I use white plexiglass. Paint the face and edges black and have it
engraved or engrave it then use a roller to paint the face and sides.

Ok, so other than good intentions and great karma, what kept the paint
out of the lettering?

If you paint it before engraving you won't have that problem. Using a
roller to paint after you engrave means very little, if any paint gets
into the lettering. I used a rubber roller like engravers use. I prefer
the paint first method, but sometimes you need to repaint after adding
engraving or damaged paint.

I might mention painting the back of the plastic prevents light leaks.

For the truly patient/crazy you can route grooves in the back for
wiring. The number of lights required depends on the size of the panel
and embedded wiring means you only have 2 wires hanging out the back.

Military/commercial lighted panels have a little coaxial connector on
the back that presses into a socket when you mount the panel. If you
ever see one of this type of panel you'll notice a little plus sign on
the front. The connector is directly behind it. Should lighting fail you
can press there to see if the connection is bad. Older panels had light
assemblies that screwed through the panel from the front.

Thanks, Dan.
That's a possibility.
