Model of Frame Casting for Model Die Casting (Roundhouse) 0-6-0 modified to accept NWSL 28:1 gear box and Greenway 51" drivers with bronze bearings. It is shown in Illustration 1 if the attached URL. It is for an HO scale locomotive, but is built to actual dimensions to avoid the limitations of Sketchup. It should be scaled down 87 times to use it in HO scale.
I built it to model a new cylinder saddle and possibly side rods matching a Union Pacific S-4 switcher to be 3D printed by a 3D printing service. This is simply a reference component and for practice in using the tool.
FWIW, this is my first model in Sketchup. Feedback is always welcome.
