I suppose we now may consider Bernhard a fairly advanced modeler whose work safely falls into the "adequate" category. -- Russ

This more or less completes the production of the individual parts for this assembly. The next steps are to prime and paint all the parts. That's a pretty time-consuming process with this small airbrush. And it's actually a shame that this means the beautiful brass finish will disappear.

And here you can see the proud master with his creation (at Christmas 2025).

During my research trip last fall, I happened to find the original drawings of the rack-and-pinion gears for the trolly's drive system in Bowling Green. I had the rack-and-pinion gears 3D-printed in nylon.

And finally, I soldered the railings to both girders.

Then I worked on the drive system for the trucks. First, the support on which the drive motor and brake are mounted.

Then, just to test it out, I installed all the drive shafts.

To mount the rails on the main girders, I mill some track gauges.

The upward-curved ends of the rails are reinforced with cast (3D-printed) supports.

The front ends of the trolly's rails are bent upward to prevent the trolly from rolling off the main girders. To bend the rails, I'm building a bending jig with profiled bending rollers.
