This is a two sided sign.
Each layer is 1" thick which makes the body of the sign 2" thick when done.
The pieces on the router are back side up (or inside up).
The groves either side of the router spindle dust shield (The yellow box) are made to accept the steel structural frame that will give the sign some strength and also provide attachment points for hanging.
This shape is 1/4" oversized, I will cut the final shape and engrave the text on the router after the glue dries.
By doing it this way I don't have to clean up the messy glue joint that the gorilla glue leaves.
