base. Refer to figure 9 for the sizes of styrene I used for this sign. Be sure to design the support to meet the dimensions of your particular sign! I ran a bead of super glue around the joint between the sign support and flat base. This increases strength and also made a slight fillet (rounding). The base was spray painted flat black and allowed to dry (figure 7).

Figure 6: The bits of styrene I used to build the hollow sign support. Figure 7: The sign support after I spray painted it black. Figure 8: The sign support with very fine river rocks glued in place.
I used very fine river gravel to create the stone veneer. I removed the larger rocks and glued individual stones to the front and two sides of the support using Pacer 560 Canopy Glue. You can’t see the back of the sign, so I didn’t bother to put any stone there. Installing the stones took about 10 minutes. I also put some stones on the top ledge but made sure the opening for the animated sign plug was clear. Then I let everything dry. Any type of stone available locally could be used – as long as they are small enough (figure 8).

I prepared the scenery surface for the sign by cutting a slot in the Masonite. First I had to remove some plaster and scrape the surface clean. I marked the plug location and the outline of the sign support on the scenery base.

Then I drilled a series of 11/32“ holes (figure 5) in the Masonite. I used a small saw to connect the holes making a slot and cleaned the slot’s edges to be sure the sign controller receptacle fit through easily. I glued the sign
