On 28 November I showed you a picture of work in progress. A 3D jigsaw puzzle.
The puzzle is now ready. It is a steam locomotive model, the drive not coming from steam of course, but from a spiral spring.
The spring is in the cabin, the driving axle is the second from the back. What looks like a chimney is rotating when the loco drives.
Everything is wood, except the axles and the spring (iron), and the small yellow things on the axles that keep the wheels in place.
