This part of the model as detailed by Bob Jones in his instructions is very delicate and complex and consists of approx 200 parts some of which are tiny.
The start of chassis construction, due to the large size and flex of the main frames i added a third spacer to keep the frames rigid. PCB spacers are ready for fitting.
PCB spacers now fitted and you can also see the cylinder plates and slidebar brackets in place but not fixed.
Wheels fitted for show and yes they do run all in contact with the rails. The gearbox has also been assembled.
