066. Crane CarThe fifth car in the train shown on the construction set's box art is labelled a crane car. It's not a bad model, but it promises more play value than it can deliver.
If you look at the illustration carefully, you'll see a knob sticking out of the cab. The implication is that it will turn the dowel, and thus raise or lower the hook at the end of the string.
Well, that knob is actually a wooden collar, and it doesn't grip the dowel very tightly. The "hook" appears to be four fiberboard washers around a small dowel. All of that is extremely light-weight. I think only a single strand of sewing thread would be thin enough to actually stay within the guides of the crane arm and move up and down.
If the crank worked. Which it doesn't. And how would you secure the thread to the dowel and washer assembly?
I'm using florist wire as a string/thread substitute for this project. I substituted a wooden collar for the washers, and secured it by bending the end of the wire after threading it through.
For a static shot, I think it worked just fine.
