Kankool frame installation – Part III(a) …
Whilst recently carrying out final adjustments to the wire-in-tube controls to turnouts 7, 9 and 12 at Kankool, I discovered a minor problem with the control of turnouts 7. On the prototype, lever 7 controlled two turnouts, both labelled ‘7’. See the diagram below. These two turnouts operated off the same single rodding run, as they were required to operate in tandem.
My original thought was that I would be able to simulate this in model form by operating both turnouts from the one control wire from the frame. This was done by passing the control wire from the frame through turnout 7 on the loop first, then terminate at turnout 7 on the main. This seemed like a good idea in theory, but when it came to adjusting the throw of each turnout, I couldn’t get both to operate successfully in tandem.
So I decided to terminate the existing control wire at turnout 7 on the loop and run a separate control wire from the frame to turnout 7 on the main and to connect it to lever 7. See the result below.
Two of the brass ferrules were soldered together to enable both control wires to terminate on the one lever.
I was now able to adjust each turnout independently from each other.
