The 3D printers are working overtime and it won't be long now until I have the inside walls printed.
I have been joining the wall sections as they were printed. Once I have all of them printed I will use Tap-cons to attach them to the concrete. I will add a small gap between
each section to allow for movement and help to avoid any buckling in the wall sections.
Here is a look at the only re-entry point for any car that gets over the inside wall and needs to get back on the track.
