I've made a start on the girders of the river over-bridge at the Cavendish end of the station. This bridge is still there but one of the girders has been removed. There are two distinct bridges, one with very conventional plate girders which supports the running lines and another bridge with really odd cast girders which supported the original coal siding, removed by the time I'm modelling.
One of the difficulties that I'm facing is that, as is inevitable, I've had to compress the overall length of the station slightly. This means that the bridge is actually slightly shorter than it ought to be. So I'm trying to compromise and make something that looks right, rather than a slavish millimetre accurate model.
I've drawn up the girders in CAD and printed them out on my new Anycubic Photon resin 3D printer.
I'm really happy with the way the girders came out, the rivet detail is crisp and I think pretty convincing.
Taking a look at the girders and the difference between two difference types of girder is very obvious. I can see from the photographs that I need to do a little bit more filing to do to remove the last of the facets from the layers of printing.
I think I may end up reprinting the main girder with the walkway and mounts for the handrail.
Still, happy with the progress.
