The river wheel is fixed with rocks in a stream, so that water can run over the full width. Powerful enough to drive the Basket Cable Car or Hammer Mill.
The rhythm of the hammering can be adjusted. Like the large and ancient examples in the blacksmith’s workshop the hammer mill can be driven by the small waterwheel, the small turbine, the riverwheel or the sail windmill.
Water fills the trough until it is too heavy and tips over, emptying out the water and causing the bell to ring. Refilling commences immediately. The water seesaw bobs and bobs and bobs and can also be operated with sand, gravel or balls.
