Finally the windmill. Scratch built using my imagination, styrene, brass, steel, aluminium, rubber, slot car gears and even a carbon fibre shaft. I also built a gearbox so it runs at a reasonable pace at 4.5v, independent of the track power supply. This is another piece salvaged from the old track, it used to be connected to a small solar cell, thus it would randomly start running when the sun came out.
That brings it up to date. Still a tonne to do but that’s ok, it’s part of the fun
