Sorry to bring back an old thread but it seems I have managed to pick another one of these up along with the matching nonpowered unit at York this past October. With my fairly recent foray into 3D printing I thought I'd try a fresh approach to setting up proper fixed pilots. After looking at several photos and a drawing or two I figured out that the MTH swinging pilot is slightly stylized and quite a bit too narrow. I used my lowly Tinkercadding skills to build one up and printed it using my Creality FDM printer to test the fit-up and to see if I was onto something. The idea was to eventually resin print it so I can get more detailing 'molded' in. Here's a shot of the final FMD test print and the potential final resin one:
The general idea is to have it mounted to the sheet metal frame so that the shell can be removed without undoing the pilots. I also tried to fashion the pilots in the general spirit of the MTH model, using style and detail queues from the original part.
At some point I may 3D print replacement plugs for the dynamic brake assemblies.
