GWR Saint Class Loco

[Mikemill]

Thanks for the kind remarks and many likes.

Interesting discussion about the cylinder offset, 2.5in in G3 scale = 0.110in hardly noticeable in a large scale model.

Is it not possible that the man frames carrying the cylinders got moved around from loco to loco. I was thinking that a set of frames requiring extra attention during stripping for maintenance might 'miss' the slot for the loco from which they were removed and would end up on another Saint.

Larry,

I don’t think that would happen, as frames & rods would have to be kept together as a set, and were certainly stamped with the loco number. I’m aware of locos changing identity, but I think the frames are the loco. Unlike wheels, boilers, brasses, etc, which were certainly interchangeable, and I’d guess interchanged, to minimise stock sitting around costing, not earning, money.

Perhaps we should open second/separate thread discussing the subject of 2 1/2" rather than drifting totally OT ...
and messing up @Mikemill 's thread about his beautiful model??

GWR Saint Class 29xx. Designed by Churchward these elegant engines deserve to be represented in G3.

The chassis have Nylon 3D printed driver wheels, Nick Bains helped to convert my 2D CAD drawings into .stl files for the printer. The axles run in low profile ball bearings mounted in sprung axle boxes.

The motor/gearbox is rated at 400rpm and drives a 3 to 1 bevel gear set to give a very slow through to elegant speed.

Hi Mike - your locomotive looks fantastic! I am building a Saint in N Gauge - she will be "Lady of the Lake". I have 3d printed the body and cylinders but the right size of driving wheels are not available in N Gauge (13.7mm 20 spoke - though I can get 14mm metal rims). You mentioned nylon 3D printed driving wheels; would you be willing to share the STL files for these so that I could re-scale them and print them?
