A couple of more old pics: The first shows the Roebling suspension bridge from further away. I wanted to see if I could make a functional suspension bridge, and the prototype fit in my theme of relatively light mining trains. Unfortunately, it is high maintenance as the T y P has been permanently banished to the garage by the majority stock holder (wife). With the difference in temp and humidity, the bridge is constantly buckling or pulling apart. Underneath the workbench the main cables are held by turnbuckles, while all of the smaller vertical stays have teeny weeny .090 nuts that are adjustable for finer tuning: These can be seen in the second pic. If I do keep the bridge i need to find a better way to attach the .090 nuts to the main wires and fix the approaches as I didnt account for the upward pull of the cables and there is a considerable hyump at each end.
