Progress on the Princess Coronation build continues with some test 3d prints for some of the details. These are only testing out ideas at this stage.

Above we see the bogie bearing pads and bracket, cylinder fronts, Ejector and brakes.

I admit that i had quite a wow! moment when I first saw the ejector.  We are exploring the idea of 3d prints for the brake shoes as it allows you to position them closer to the wheels without risking a short. Where the front one squeezes in between the front driving wheel and the rear bogie wheel seems particularly advantageous.

Image
Pony truck axlebox and springs along with some of the under cab pipework.  One of the small AWS cylinders can be seen on the footplate

Image
More AWS bits - this time on the firemans side.  The roof is still a loose fit at this stage.

State of play so far.
