Maybe someday the progress you, Mark, and Randy are making will get me motivated to get some work done on my layout. In the meantime, I'll just sit on my butt and critique the work of others. ![Smile]()
Those swivel plates look like a lazy susan base. Are you sure they will operate long term in the vertical orientation with the weight of the layout? Many things (like early hard drives) are only engineered to operate reliably in one plane. Run of the mill ball bearings only work in a single plane. The bearings in these brackets (if there are any) are likely placed so they don't support any weight when mounted vertically.
