Title: GWR Saint Class Loco
Post by: 753 on Jun 03 2022 14:00
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 of this parish 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.

He's at it again! There's just no stopping him, great choice of loco though! Another masterpiece in the making.

I'm delighted to be involved in this project. Adopting modern manufacturing technologies (in this case, 3D printing in hard plastics) can have a big impact on the hobby. For wheel centres we are no longer limited to what is commercially available. If it can be drawn, it can be made and at a sensible price.

Thanks for the comments
Further progress on the Saint, the cylinder / smokebox saddle is a muti part fabrication to emulate the full size practice, the crossheads are a five part fabrication.

Progress on the Saint, the smokebox, boiler barrel, and firebox are made separate modules. The firebox and barrel bolt together while the barrel plugs into the smokebox. Fitting the firebox and barrel over the splashers take a lot of fettling.

Making good progress, Mike.
Unlike mine, which is on the back burner .... too many other distractions at present.
Regards,
John.

The Saint is complete, progress over the last couple of months has been slow due to my wife's illness and then we both had Covid.
I now have G3 examples of engines designed by the GWR's four most influential CME's Gooch, Armstrong, Dean and Churchward.
So, Lady Macbeth is done, as its my birthday tomorrow what better present could you wish for but a G3 Saint.
