I've been pondering this new build for some time. It seems like the best cure for over-think is to cut some wood. Again, the model won't be very specifically prototype because the lumber I use is just stuff from the art supply store that costs $0.29 per strip. I am once again using a scaled computer print out as my reference. Since the lumber doesn't exactly match anything I am just fudging the sizes.
This little Baggage car should be pretty awesome despite my Crap Building techniques.
The Primary rule for Crap Building is: Does it feel good to make something with your hands? If so, just keep building.
