My Porky Pig sign from Miller Engineering arrived a couple days ago. So I decided to make a drive-in using the sign. My focus is on having a display that will be versatile enough to be able to change the sign easily. Here are some pictures of my progress.
Using a 10-1/2" X 7-1/2" piece of 1/4" plywood I cut a 4" hole with a hole saw.
I had to come up with something that I could just slide the sign into and it would stay in place. 
Next I needed something to hold the battery pack. I also made some side supports so it would stand up.
Just glued a little facing on the battery holder.
Next is a place to hold the circuit board / switch.
Glued a facing on the circuit board holder.
As you can see, everything is easily removal to change out the signs and easy access to the on/off switch.
Now to figure out how to keep the sign centered and get the screen painted. This should be a lot of fun to have on a layout.
All wood is just scrap material from my wood bin. Any suggestions on how to improve on this project are welcome.
