I have been waiting for the arrival of some materials for the Wesso section before I could proceed with it any further so I decided to get started building the bench work for the Carlin section.
This section is 91 inches long and meets the next section to it's right between wall brackets. When both sections are both ready to be installed, they will be bolted together.
This section will have removable bottom plates with LED lights mounted on them to light up the staging yard and the display case.
This photo shows the difference in elevation between leaving the lower helix at Winnemucca on the west end of the layout and the east end of Carlin. The climb around the entire room will be gradual. Most of it will be in the canyon at the opposite end of the room.
