A wooden trolley car that runs

[ezdays]

Well, here we are again, these are really interesting, challenging and fun, and I know I'm hooked. I may have to see a shrink to shed my addiction. So, I have one more of these wooden "puzzles", (or really, models). This one is a trolley car that has a spring-wound drive motor. It also has tracks, and a catenary system with overhead (wooden) wires for use as a static display. I already have the steam engine on a floating shelf I built next to my rolling stock display case, and so that's my plan, to build another shelf for the trolley.

This one has some 370 parts, but will take more time because of the drive engine and the fact that parts used aren't in sequence. In some kits, you use parts from sheet A before you go to sheet B, but this one starts off with parts from sheet H, then E, then G, and so on, mainly because each sheet is a different thickness plus assembly starts off with the gear train. Learning from the steam loco built, I will double and triple check the gears as they are installed. One loose gear or broken shaft negates all efforts to run this thing.

Anyway, this is what I'm trying to build, and the instructions are in a book rather than a large sheet. There are only 10 steps to building this, but.... I counted over 170 sub-steps, so I'm thinking 20 or 25 hours to build just as long as there are no real issues.
