First Benchwork Framing

Now that the Wall brackets are all up. I started working on the what the depth of my layout would be. I originally thought 18", as I had a couple of sections from the old layout already at 18" depth and could use them as is. During the mock-up and laying some test tracks for the foreground and back mainlines it seem to close so I am going to use 21" depth. We will see how this goes, so here a couple of photos of the frame work for the 21" depth
