Another piece of old 2 x 2 Ntrak module leg was installed on the outer edge of the "Winnemucca" section on the top, this is grey in the photo.
Helix Progress post I had mentioned that there seemed to be a bit of a twist occurring in the helix sections causing there to be a slight difference in the spacing in some places. I was able to solve this by making 4 spacing strips that hold the outer edge at a spacing the 2-/14 inches between levels. One of these was mounted on the outer edge between each all thread rod.
This photo shows the connections for the inner or WP tracks. The connections for the outer or SP tracks are on the opposite side of the helix.
While this marks the completion of this lower helix, there will eventually be another helix stacked on top of this one that will connect the other end of the layout to a return loop and siding that will be above Wesso after the layout goes all the way around the room.
