The marquee, the sign at the top of the monitor, is built from two strips of plexiglass. The artwork is sandwiched between them. A light source lights the marquee from behind.
The light source behind the marquee should be bright and cool. Traditional light bulbs are too hot to install behind plexiglass. They would melt the marquee and could even cause a fire.
A florescent light strip or a couple of LED lights are a better option. They keep the heat down.
Tie the light strip into the power system of the arcade cabinet.
Securing the Artwork
Cut two identical plexiglass panels that just fit into the marquee's opening. The panels must touch the blocks once they are installed.
Attach the artwork to the inner panel. Remove all air bubbles and cover the artwork with the second panel. The blocks will hold the sandwich in place.
Securing the Plexiglass
The plexiglass is held in place by frame of 1/4" blocks. There is an inner frame, and an outer frame.
The inner frame keeps the glass from falling into the cabinet. It is glued into place.
The outer frame keeps the glass from falling outward. It is pinned into place to allow the artwork to be updated or repaired, if necessary.
Rip the thin 1/4" blocks from larger stock. Use a guide block to position the inner frame. Attach it with glue. If you have a pin nail, pin the frame in place. Otherwise use clamps.
The outer frame should be pinned in place, if possible. If you don't have a pin nailer, use hot glue or super glue. Not a lot is needed to hold the marquee in place.
The marquee is an important component of the arcade cabinet. It is a focal point and for many defines what the arcade is all about.
